Orders commonly take one  to three weeks to fill depending on how busy we are. You are more than welcome to contact us before ordering if you have <strong>any</strong> questions. Novaworldorders@gmail.com\r\n\r\nWe ship all orders USPS priority mail. Shipping in the US commonly takes 3 days. International shipping commonly takes 2 weeks but can take up to 3 if it gets stuck in customs.\r\n\r\n<hr />\r\n\r\n<h1>Double VS Single</h1>\r\nThe NovaDrone is available as a PCB, a kit and as an assembled unit.\r\n\r\nEach of these options is available as a single or double unit. The double unit is essentially two NovaDrones on a single <a href=\"http://casperelectronics.com/wp-content/uploads/NovaDrone/store/doublePCB.lone_.better.jpg\">illustrated PCB</a>. The double unit shares a single power input and single audio output. The audio signals can be separated by using both audio jacks.\r\n\r\n<hr />\r\n\r\n<h1>THE ADVENTURE KIT</h1>\r\nThe <strong>adventure kit</strong> is a collection of electrical components which work especially well with the adventure board (the circuit bending breadboard at the bottom of the PCB). This kit will allow you to explore a wide range of novice to advanced bends and hacks ranging from light controlled pitch to distortion and filter circuits.\r\n\r\n<hr />\r\n\r\n<h1>POWER SUPPLY</h1>\r\nWe are no longer selling power supplies. We may offer them again if we find a good distributor.\r\n\r\nYou can use any power supply that is rated 9-24VDC, negative ring and 2.5mm barrel. These are very common specs for a power supply and finding one in your location should be easy. Maybe you already have one! The input is diode and regulator protected so there\'s very little likelihood that the circuit will be damaged from plugging in the wrong power supply.\r\n\r\n<hr />\r\n<h2>WE ARE OUT OF THE OFFICE UNTIL MAY 25TH.

Orders commonly take one  to three weeks to fill depending on how busy we are. You are welcome to contact us before ordering if you have any questions. Novaworldorders@gmail.com\r\n\r\nWe ship all orders USPS priority mail. Shipping in the US commonly takes 3 days. International shipping commonly takes 2 weeks but can take up to 3 if it gets stuck in customs.\r\n\r\n<hr />\r\n\r\n<h1>Double VS Single</h1>\r\nThe NovaDrone is available as a PCB, a kit and as an assembled unit.\r\n\r\nEach of these options is available as a single or double unit. The double unit is essentially two NovaDrones on a single <a href=\"http://casperelectronics.com/wp-content/uploads/NovaDrone/store/doublePCB.lone_.better.jpg\">illustrated PCB</a>. The double unit shares a single power input and single audio output. The audio signals can be separated by using both audio jacks.\r\n\r\n<hr />\r\n\r\n<h1>THE ADVENTURE KIT</h1>\r\nThe <strong>adventure kit</strong> is a collection of electrical components which work especially well with the adventure board (the circuit bending breadboard at the bottom of the PCB). This kit will allow you to explore a wide range of novice to advanced bends and hacks ranging from light controlled pitch to distortion and filter circuits.\r\n\r\n<hr />\r\n\r\n<h1>POWER SUPPLY</h1>\r\nWe are no longer selling power supplies. We may offer them again if we find a good distributor.\r\n\r\nYou can use any power supply that is rated 9-24VDC, negative ring and 2.5mm barrel. These are very common specs for a power supply and finding one in your location should be easy. Maybe you already have one! The input is diode and regulator protected so there\'s very little likelihood that the circuit will be damaged from plugging in the wrong power supply.\r\n\r\n<hr />\r\n<h2>WE ARE OUT OF THE OFFICE UNTIL MAY 25TH.

These are very common specs for a power supply and finding one in your location should be easy. Maybe you already have one!

I am a musician, sculptor, inventor and teacher--though it is crucial to my work that I not employ any one of these roles to the exclusion of the others. My practice takes place at their intersection or sometimes creates intersections where there might not have been. The overlap itself fulfills a desire to challenge, entertain and inspire my audience. By blending mediums or practices thought to exist on their own, I hope to incite a perception of new possibility. Through all of my work, I strive to destabilize preconceptions of role and function as well as dissolve the barriers between producer and consumer. Particularly to this end, I employ the practice of electronics hacking and circuit bending of common technologies to illustrate that function need not be dictated to the end user.\r\n<a href=\"http://casperelectronics.com/images/finishedpieces/installations/Specter/the%20orb.jpg\"><img title=\"\" alt=\"\" src=\"http://casperelectronics.com/images/finishedpieces/installations/Specter/_the%20orb.jpg\" width=\"400\" height=\"266\" /></a>','Artists Statement',0,'','inherit','open','closed','','211-revision-v1','','','2013-12-14 14:47:02','2013-12-14 19:47:02','',211,'http://casperelectronics.com/2013/12/14/211-revision-v1/',0,'revision','',0),(2107,2,'2015-10-27 12:00:20','2015-10-27 17:00:20','<a href=\"http://casperelectronics.com/wp-content/uploads/template.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/template-460x524.jpg\" alt=\"Template\" width=\"460\" height=\"524\" class=\"alignnone size-large wp-image-2130\" /></a>The following videos will show you how to build a variety of simple musical circuits.

Low parts count, wide frequency range. Easy to tweak. \r\nAll that\'s needed is an inverter of some kind (in this case its a <a href=\"https://en.wikipedia.org/wiki/Schmitt_trigger\">Schmitt trigger</a>), a capacitor and a resistor.\r\nThe frequency of the oscillator is controlled by the capacitor and resistor. Basically the capacitor sets the range and the resistor changes the freq within that range.\r\nIMPORTANT NOTE:\r\nIn order to use the outputs of this oscillator it is necessary to buffer them. If the outputs are connected directly to a component or circuit that PULLS current from the OSC (like a speaker) there will be little or no current left within the circuit to make it oscillate. The role of the buffer is to look at the behavior of a circuit and reproduce that behavior without pulling any current away from the original circuit. The good news is that most audio equipment you would connect the OSC to has buffered inputs. Mixers, amplifiers, most guitar pedals etc. The \"triangle\" wave output is far more sensitive than the square wave, as well as offering substantially lower amplitude. If you want to use the triangle wave in a larger circuit it is very likely you will have to build an extra buffer as shown in the image below. \r\n \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-oscillator.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-oscillator-460x237.png\" alt=\"Basic Oscillator\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2114\" /></a>\r\n\r\nMORE OSCILLATORS\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/more-oscillators.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/more-oscillators-460x237.png\" alt=\"More Oscillators\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2117\" /></a>\r\n\r\nOSCILLATOR WITH RATE INDICATION LED\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/LFO_w_LED.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/LFO_w_LED.png\" alt=\"LFO W LED\" width=\"385\" height=\"199\" class=\"alignnone size-full wp-image-2118\" /></a>\r\n\r\nSIMPLE PITCH MODULATION\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/pitchmod.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/pitchmod-460x237.png\" alt=\"Pitchmod\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2119\" /></a>\r\n\r\nSYNCING OSCILLATORS\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/sync.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/sync-460x237.png\" alt=\"Sync\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2120\" /></a>\r\n','Video #1: Oscillators',0,'','publish','open','closed','','video-1-oscillators','','','2016-12-30 16:15:30','2016-12-30 21:15:30','',2107,'http://casperelectronics.com/?page_id=2109',0,'page','',0),(2122,2,'2015-10-29 11:31:42','2015-10-29 16:31:42','The following videos will show you how to build a variety of simple musical circuits.

Low parts count, wide frequency range. Easy to tweak. \r\nAll that\'s needed is an inverter of some kind (in this case its a Schmitt trigger), a capacitor and a resistor.\r\nThe frequency of the oscillator is controlled by the capacitor and resistor. Basically the capacitor sets the range and the resistor changes the freq within that range.\r\nIMPORTANT NOTE:\r\nIn order to use the outputs of this oscillator it is necessary to buffer them by some means. If the outputs are connected directly to a component or circuit that PULLS current from the OSC (like a speaker) there will be little or no current left within the circuit to make it oscillate. The role of the buffer is to look at the behavior of a circuit and reproduce that behavior without pulling any current away from the original circuit. The good news is that most audio equipment you would connect the OSC to has buffered inputs. Mixers, amplifiers, most guitar pedals all have buffered inputs. The \"triangle\" wave output is far more sensitive than the square wave, as well as offering substantially lower amplitude. If you want to use the triangle wave in a larger circuit it is very likely you will have to build an extra buffer as shown in the image below. \r\n \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-oscillator.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-oscillator-460x237.png\" alt=\"Basic Oscillator\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2114\" /></a>\r\n\r\nMORE OSCILLATORS\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/more-oscillators.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/more-oscillators-460x237.png\" alt=\"More Oscillators\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2117\" /></a>\r\n\r\nOSCILLATOR RATE INDICATION WITH LED\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/LFO_w_LED.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/LFO_w_LED.png\" alt=\"LFO W LED\" width=\"385\" height=\"199\" class=\"alignnone size-full wp-image-2118\" /></a>\r\n\r\nSIMPLE PITCH MODULATION\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/pitchmod.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/pitchmod-460x237.png\" alt=\"Pitchmod\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2119\" /></a>\r\n\r\nSYNCING OSCILLATORS\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/sync.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/sync-460x237.png\" alt=\"Sync\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2120\" /></a>\r\n','Video #1: Oscillators',0,'','inherit','open','closed','','2109-revision-v1','','','2015-10-29 14:02:10','2015-10-29 19:02:10','',2109,'http://casperelectronics.com/2015/10/29/2109-revision-v1/',0,'revision','',0),(2136,2,'2015-10-29 14:06:11','2015-10-29 19:06:11','','BASICosc',0,'','inherit','open','closed','','basicosc','','','2015-10-29 14:06:11','2015-10-29 19:06:11','',2109,'http://casperelectronics.com/wp-content/uploads/BASICosc.jpg',0,'attachment','image/jpeg',0),(2160,2,'2016-01-15 10:19:12','2016-01-15 15:19:12','<iframe width=\"450\" height=\"240\" src=\"https://www.youtube.com/embed/FaoJaLmZaL4\" frameborder=\"0\" allowfullscreen></iframe>\r\nPart 2 <a href=\" Permalink: http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-2-sequencers/ ‎Edit\">HERE</a>\r\ntable of contents:\r\n\r\n\r\nBASIC OSCILLATOR:\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/BASICosc.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/BASICosc-460x427.jpg\" alt=\"BASICosc\" width=\"460\" height=\"427\" class=\"alignnone size-large wp-image-2136\" /></a>\r\nThis is one of the simplest oscillators you can build.

Now its time to sequence those oscillators to make melodies and complex patterns. The video above covers several kinds of sequencers in detail. Below I have provided schematics and build diagrams for the examples in the video. I tried to make the diagrams as complete as possible but there is still much more to explore.

Low parts count, wide frequency range. Easy to tweak. \r\nAll that\'s needed is an inverter of some kind (in this case its a <a href=\"https://en.wikipedia.org/wiki/Schmitt_trigger\">Schmitt trigger</a>), a capacitor and a resistor.\r\nThe frequency of the oscillator is controlled by the capacitor and resistor. Basically the capacitor sets the range and the resistor changes the freq within that range.\r\nIMPORTANT NOTE:\r\nIn order to use the outputs of this oscillator it is necessary to buffer them. If the outputs are connected directly to a component or circuit that PULLS current from the OSC (like a speaker) there will be little or no current left within the circuit to make it oscillate. The role of the buffer is to look at the behavior of a circuit and reproduce that behavior without pulling any current away from the original circuit. The good news is that most audio equipment you would connect the OSC to has buffered inputs. Mixers, amplifiers, most guitar pedals etc. The \"triangle\" wave output is far more sensitive than the square wave, as well as offering substantially lower amplitude. If you want to use the triangle wave in a larger circuit it is very likely you will have to build an extra buffer as shown in the image below. \r\n \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-oscillator.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-oscillator-460x237.png\" alt=\"Basic Oscillator\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2114\" /></a>\r\n\r\nMORE OSCILLATORS\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/more-oscillators.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/more-oscillators-460x237.png\" alt=\"More Oscillators\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2117\" /></a>\r\n\r\nOSCILLATOR WITH RATE INDICATION LED\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/LFO_w_LED.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/LFO_w_LED.png\" alt=\"LFO W LED\" width=\"385\" height=\"199\" class=\"alignnone size-full wp-image-2118\" /></a>\r\n\r\nSIMPLE PITCH MODULATION\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/pitchmod.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/pitchmod-460x237.png\" alt=\"Pitchmod\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2119\" /></a>\r\n\r\nSYNCING OSCILLATORS\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/sync.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/sync-460x237.png\" alt=\"Sync\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2120\" /></a>\r\n','Video #1: Oscillators',0,'','inherit','open','closed','','2109-revision-v1','','','2016-01-18 07:20:35','2016-01-18 12:20:35','',2109,'http://casperelectronics.com/2016/01/18/2109-revision-v1/',0,'revision','',0),(2159,2,'2016-01-15 10:05:26','2016-01-15 15:05:26','<iframe width=\"450\" height=\"240\" src=\"https://www.youtube.com/embed/t7JYOIYqMEY\" frameborder=\"0\" allowfullscreen></iframe>\r\nIn the <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-1-oscillators/ \">first tutorial</a> I covered basic oscillators theory and construction.

Low parts count, wide frequency range.

It\'s dirty and clicky and generally crappy but I\'ve found it to be a surprisingly endearing circuit to play with. Just after filming the tutorial I realized it could also be used as an equally crappy but totally effective low pass voltage controlled filter! An unexpected feature from a cheap lil\' voice recording chip :)  I\'ve put info on that <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-3-lofi-sampler/voice-recorder-based-voltage-controlled-filter/\">here</a>.\r\n\r\n\r\nFor this project you will need:\r\n\r\n-<a href=\"https://www.ee.iitb.ac.in/uma/~wel/wel12/Components%20Records/digital%20ic%20datasheet/cd40106.pdf\">CD40106</a> Schmitt trigger IC\r\n-<a href=\"http://www.intersil.com/content/dam/Intersil/documents/cd40/cd4020bms-24bms-40bms.pdf\">CD4040</a> Binary counter/clock divider IC\r\n-<a href=\"http://www.tuxgraphics.org/npa/outdoor-doorbell/ISD1800_datasheet.pdf\">ISD1820</a> Voice recording IC. These may be hard to find in shops, but a quick ebay search will give you lots of options. \r\n-1k, 10k, 47k, 100k, 470k, 1M resistors\r\n-100k potentiometers\r\n-0.1uF, 1uF, 10uF capacitors\r\n-a breadboard or two\r\n-a 5volt power supply or 9volt battery with a 5volt regulator like the L78L05\r\n-lots of jumper wires\r\n-alligator clips and some kind of metal objects to clip to in order to make a touch panel for controlling the pitch of the sample. \r\n\r\n\r\n<strong>BUILDING A BASIC SAMPLER</strong>\r\nFirst we\'ll start with the most basic sampler circuit. This is taken almost directly from the <a href=\"http://www.tuxgraphics.org/npa/outdoor-doorbell/ISD1800_datasheet.pdf\">ISD1820 data sheet</a>. I\'ve added:\r\n-extended range on the pitch control \r\n-line in \r\n-stereo headphone output \r\n\r\n\r\n             <em>basic ISD1820 circuit</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler-460x326.png\" alt=\"Simple Sampler\" width=\"460\" height=\"326\" class=\"alignnone size-large wp-image-2216\" /></a>\r\n\r\n<strong>ISD1820</strong>\r\nFirst a note about the ISD1820. This is not a \"good\" sampler chip... The sound quality is bad, there\'s a moment of silence when the sample loops and, most annoyingly, it clicks when the sample starts. These things can\'t really be avoided. But despite all this I have found it to be genuinely fun to play with and depending on what you are recording, it can actually be a pretty useful little sampler. Furthermore, this is as cheap and simple as DIY samplers get. I would say this is about as simple as audio circuits in general get, which counts for something. And I\'m happy to find that the chip is quite flexible allowing wide pitch control range and modulation options (touch control, CV control, light sensors, potentiometers), and some interesting amplitude control options.  \r\n\r\n<strong>\r\nCircuit details:</strong>\r\nNOTE ABOUT BUTTONS! all buttons in this circuit connect a pin on the isd1820 to +5 volts. This is also called setting the pin high. This can be achieved with the button as shown but also with various voltage generators, sequencers, gate dividers etc. \r\n\r\n<strong>PITCH CONTROL-</strong> There are several ways to adjust the pitch of this chip. In this schematic I show one of the simplest methods that requires minimal parts and gives you a very wide pitch sweep. R14 determines the low range of the pitch and using 470k gives you about as low a pitch as possible. If you want a higher base pitch, increase this value. \r\n<strong>RECORD BUTTON-</strong> The chip will record as long as the record input pin is high and until the buffer is full. The length of the recording buffer is dependent on the pitch setting and is rated between 8 and 20 seconds under \"normal\" settings. At lower pitch the recording time is much longer but the quality is also much lower. \r\nThe record feature starts to malfunction at high and low pitch settings! It\'s best to do your recording at a middle pitch setting. \r\nC5 on the record button helps \"debounce\" the signal and minimizes false triggers. \r\n \r\n<strong>PLAY BUTTONS-</strong>  \"play gate\" and \"play trig\" are two different inputs to play the sample. \"play gate\" will play the sample as long as the input to that pin is high (5 volts) \"play trig\" will run the sample for its duration as soon as it receives 5 volts at the pin, regardless of how long the pulse is. Both are useful but I primarily use the \"play trig\" input. \r\n<strong>REC/SAMPLE END LED-</strong> This light is on while the chip is in record mode. It ALSO will flash briefly at the end of playing back a sample. \r\nR8 determines the brightness of the LED.  \r\n<strong>LOOP SWITCH-</strong> The loop switch connects the output of the LED pin to the \"play trig\" input. That means that at the end of the sample the light will flash. This pulse will also retrigger the sample...making a loop. \r\n<strong> FEED THROUGH SWITCH-</STRONG> Setting this pin high passes the input signal to the output but along the way it goes through the chip and is filtered. The Filter cut is determined by the pitch setting. Therefore with a wide pitch range you are able to achieve a nice low pass filter. I go over this in more detail <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-3-lofi-sampler/voice-recorder-based-voltage-controlled-filter/\">here</a>\r\n\r\n<strong>MIC-</strong> You can use any ol electret mic for this circuit. \r\nR4,R5,C3 & C4 power and decouple the mic input so it works. \r\n<strong>SIGNAL IN-</strong> R1,R2, R3, R9 and C1 buffer and attenuate an external signal. It\'s necessary to dramatically lower most signals to avoid strong clipping. Use lower value resistors on the input for quieter signals (computer, etc) and higher value for louder ones (modular synth, etc). \r\n<strong>HEADPHONE OUT-</strong> C10, R6 and R7 make up an output buffer and dual mono signal splitter. This allow you to connect the mono signal from the ISD1820 to a stereo headphone jack. This can also be done by simply connecting the signal to the left and right lugs of the jack. The problem with this is that plugging a <strong>mono</strong> cable into a stereo jack shorts the left output to ground. So if the signal is connected directly to left and right it will work with headphones but if you plug in a mono jack it will short out the audio signal and you will get no output. The two resistors solve this issue. \r\nBUT adding these means you can\'t add the speaker in series with the jack (common configuration that lets you use the jack as a speaker switch). To do this you can use the schematic below. The downside of this is that you will only get the signal in the right ear of your headphones. \r\n\r\n\r\n            <em>mono output with in-line speaker</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/speaker.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/speaker-460x237.png\" alt=\"Speaker\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2201\" /></a>\r\n\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-inV2-1.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-inV2-1-460x358.png\" alt=\"Basic Sampler W Line InV2\" width=\"460\" height=\"358\" class=\"alignnone size-large wp-image-2296\" /></a>\r\n\r\n\r\n\r\n<strong>ADDING MORE PITCH CONTROL</strong>\r\n\r\n The ROSC in pin is intended to be connected to ground through a resistor to set the pitch. <a href=\"http://casperelectronics.com/wp-content/uploads/ROSCchart.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/ROSCchart-200x79.jpg\" alt=\"ROSCchart\" width=\"200\" height=\"79\" class=\"alignnone size-medium wp-image-2210\" /></a>\r\nThat resistor can be easily be replaced or used in parallel with touch and/or light sensors to control the pitch.  \r\nIt\'s possible to provide a very wide pitch sweep by connecting ROSC to a voltage divider between +&- as shown in the drawing below.\r\n\r\n<em>pitch control potentiometer</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/pitch-control.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/pitch-control-460x237.png\" alt=\"Pitch Control\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2207\" /></a>\r\n\r\nA CV input jack can be added as shown in the picture below. This allows you to interface with modular synthesizers and other electronics. \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/CVcontrol.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/CVcontrol-460x237.png\" alt=\"CVcontrol\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2219\" /></a>\r\n\r\n<strong>MODULAR SAMPLER</strong>\r\nAdd jacks to interface your sampler with a modular synth!\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Modular-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Modular-Sampler-460x216.png\" alt=\"Modular Sampler\" width=\"460\" height=\"216\" class=\"alignnone size-large wp-image-2220\" /></a>\r\n\r\n<strong>SYNTH/SAMPLER</strong>\r\nThis is the basic sampler circuit above with some extra tricks to allow touch controlled modulation and a built tone generator to record and tweak. One of the coolest things about this version is the touch interface. Each pad is connected to a clock output from a divider. By touching the pitch base (the long strip below the touch pads) and any of the clock pads you can make very interesting rhythmic sequences. The divider can be synced to external gear, but I wanted to keep the circuit simple so there is no buffering. It will work with some (most) devices but not all.  \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Sampler_With_synth.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Sampler_With_synth-460x204.png\" alt=\"Sampler With Synth\" width=\"460\" height=\"204\" class=\"alignnone size-large wp-image-2222\" /></a>','Video #3: LoFi Sampler',0,'','publish','open','closed','','video-3-lofi-sampler','','','2016-12-30 16:14:37','2016-12-30 21:14:37','',2107,'http://casperelectronics.com/?page_id=2177',0,'page','',0),(2178,2,'2016-06-14 05:35:30','2016-06-14 10:35:30','','Video #3: LoFi Sampler',0,'','inherit','open','closed','','2177-revision-v1','','','2016-06-14 05:35:30','2016-06-14 10:35:30','',2177,'http://casperelectronics.com/2016/06/14/2177-revision-v1/',0,'revision','',0),(2180,2,'2016-06-14 07:30:12','2016-06-14 12:30:12','<iframe width=\"450\" height=\"240\" src=\"https://www.youtube.com/embed/ECSYLTB_sbw\" frameborder=\"0\" allowfullscreen></iframe>\r\nThis is part three of a three part series on DIY synth building. \r\nPart 1: Oscillators\r\nPart 2: Sequencers\r\nPart 3: Samplers','Video #3: LoFi Sampler',0,'','inherit','open','closed','','2177-revision-v1','','','2016-06-14 07:30:12','2016-06-14 12:30:12','',2177,'http://casperelectronics.com/2016/06/14/2177-revision-v1/',0,'revision','',0),(2182,2,'2016-06-22 05:42:25','2016-06-22 10:42:25','<iframe width=\"450\" height=\"240\" src=\"https://www.youtube.com/embed/ECSYLTB_sbw\" frameborder=\"0\" allowfullscreen></iframe>\r\nThis is part three of a three part series on DIY synth building. \r\nPart 1: <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-1-oscillators/\">Oscillators</a>\r\nPart 2: <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-2-sequencers/\">Sequencers</a>\r\nPart 3: Samplers','Video #3: LoFi Sampler',0,'','inherit','open','closed','','2177-revision-v1','','','2016-06-22 05:42:25','2016-06-22 10:42:25','',2177,'http://casperelectronics.com/2016/06/22/2177-revision-v1/',0,'revision','',0),(2183,2,'2016-06-22 06:23:28','2016-06-22 11:23:28','<iframe width=\"450\" height=\"240\" src=\"https://www.youtube.com/embed/FaoJaLmZaL4\" frameborder=\"0\" allowfullscreen></iframe>\r\nThis is part 1 of a 3 part series. \r\nIn <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-2-sequencers/\">part 2</a> i talk about sequencers\r\n<a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-3-lofi-sampler/\">Part 3</a> combines the first 2 lessons to make a more complex sampler circuit.\r\n\r\nBASIC OSCILLATOR:\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/BASICosc.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/BASICosc-460x427.jpg\" alt=\"BASICosc\" width=\"460\" height=\"427\" class=\"alignnone size-large wp-image-2136\" /></a>\r\nThis is one of the simplest oscillators you can build.

This is taken almost directly from the <a href=\"http://www.tuxgraphics.org/npa/outdoor-doorbell/ISD1800_datasheet.pdf\">ISD1820 data sheet</a>. I\'ve added:\n-extended range on the pitch control \n-line in \n-stereo headphone output \n\n\n             <em>basic ISD1820 circuit</em>\n<a href=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler-460x326.png\" alt=\"Simple Sampler\" width=\"460\" height=\"326\" class=\"alignnone size-large wp-image-2216\" /></a>\n\n<strong>ISD1820</strong>\nFirst a note about the ISD1820. This is not a \"good\" sampler chip... The sound quality is bad, there\'s a moment of silence when the sample loops and, most annoyingly, it clicks when the sample starts. These things can\'t really be avoided. But despite all this I have found it to be genuinely fun to play with and depending on what you are recording, it can actually be a pretty useful little sampler. Furthermore, this is as cheap and simple as DIY samplers get. I would say this is about as simple as audio circuits in general get, which counts for something. And I\'m happy to find that the chip is quite flexible allowing wide pitch control range and modulation options (touch control, CV control, light sensors, potentiometers), and some interesting amplitude control options.  \n\n<strong>\nCircuit details:</strong>\nNOTE ABOUT BUTTONS! all buttons in this circuit connect a pin on the isd1820 to +5 volts. This is also called setting the pin high. This can be achieved with the button as shown but also with various voltage generators, sequencers, gate dividers etc. \n\n<strong>PITCH CONTROL-</strong> There are several ways to adjust the pitch of this chip. In this schematic I show one of the simplest methods that requires minimal parts and gives you a very wide pitch sweep. R14 determines the low range of the pitch and using 470k gives you about as low a pitch as possible. If you want a higher base pitch, increase this value. \n<strong>RECORD BUTTON-</strong> The chip will record as long as the record input pin is high and until the buffer is full. The length of the recording buffer is dependent on the pitch setting and is rated between 8 and 20 seconds under \"normal\" settings. At lower pitch the recording time is much longer but the quality is also much lower. \nThe record feature starts to malfunction at high and low pitch settings! It\'s best to do your recording at a middle pitch setting. \nC5 on the record button helps \"debounce\" the signal and minimizes false triggers. \n \n<strong>PLAY BUTTONS-</strong>  \"play gate\" and \"play trig\" are two different inputs to play the sample. \"play gate\" will play the sample as long as the input to that pin is high (5 volts) \"play trig\" will run the sample for its duration as soon as it receives 5 volts at the pin, regardless of how long the pulse is. Both are useful but I primarily use the \"play trig\" input. \n<strong>REC/SAMPLE END LED-</strong> This light is on while the chip is in record mode. It ALSO will flash briefly at the end of playing back a sample. \nR8 determines the brightness of the LED.  \n<strong>LOOP SWITCH-</strong> The loop switch connects the output of the LED pin to the \"play trig\" input. That means that at the end of the sample the light will flash. This pulse will also retrigger the sample...making a loop. \n<strong> FEED THROUGH SWITCH-</STRONG> Setting this pin high passes the input signal to the output but along the way it goes through the chip and is filtered. The Filter cut is determined by the pitch setting. Therefore with a wide pitch range you are able to achieve a nice low pass filter. I go over this in more detail <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/video-3-lofi-sampler/voice-recorder-based-voltage-controlled-filter/\">here</a>\n\n<strong>MIC-</strong> You can use any ol electret mic for this circuit. \nR4,R5,C3 & C4 power and decouple the mic input so it works. \n<strong>SIGNAL IN-</strong> R1,R2, R3, R9 and C1 buffer and attenuate an external signal. It\'s necessary to dramatically lower most signals to avoid strong clipping. Use lower value resistors on the input for quieter signals (computer, etc) and higher value for louder ones (modular synth, etc). \n<strong>HEADPHONE OUT-</strong> C10, R6 and R7 make up an output buffer and dual mono signal splitter. This allow you to connect the mono signal from the ISD1820 to a stereo headphone jack. This can also be done by simply connecting the signal to the left and right lugs of the jack. The problem with this is that plugging a <strong>mono</strong> cable into a stereo jack shorts the left output to ground. So if the signal is connected directly to left and right it will work with headphones but if you plug in a mono jack it will short out the audio signal and you will get no output. The two resistors solve this issue. \nBUT adding these means you can\'t add the speaker in series with the jack (common configuration that lets you use the jack as a speaker switch). To do this you can use the schematic below. The downside of this is that you will only get the signal in the right ear of your headphones. \n\n\n            <em>mono output with in-line speaker</em>\n<a href=\"http://casperelectronics.com/wp-content/uploads/speaker.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/speaker-460x237.png\" alt=\"Speaker\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2201\" /></a>\n\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-inV2-1.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-inV2-1-460x358.png\" alt=\"Basic Sampler W Line InV2\" width=\"460\" height=\"358\" class=\"alignnone size-large wp-image-2296\" /></a>\n\n\n\n<strong>ADDING MORE PITCH CONTROL</strong>\n\n The ROSC in pin is intended to be connected to ground through a resistor to set the pitch. <a href=\"http://casperelectronics.com/wp-content/uploads/ROSCchart.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/ROSCchart-200x79.jpg\" alt=\"ROSCchart\" width=\"200\" height=\"79\" class=\"alignnone size-medium wp-image-2210\" /></a>\nThat resistor can be easily be replaced or used in parallel with touch and/or light sensors to control the pitch.  \nIt\'s possible to provide a very wide pitch sweep by connecting ROSC to a voltage divider between +&- as shown in the drawing below.\n\n<em>pitch control potentiometer</em>\n<a href=\"http://casperelectronics.com/wp-content/uploads/pitch-control.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/pitch-control-460x237.png\" alt=\"Pitch Control\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2207\" /></a>\n\nA CV input jack can be added as shown in the picture below. This allows you to interface with modular synthesizers and other electronics. \n<a href=\"http://casperelectronics.com/wp-content/uploads/CVcontrol.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/CVcontrol-460x237.png\" alt=\"CVcontrol\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2219\" /></a>\n\n<strong>MODULAR SAMPLER</strong>\nAdd jacks to interface your sampler with a modular synth!\n<a href=\"http://casperelectronics.com/wp-content/uploads/Modular-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Modular-Sampler-460x216.png\" alt=\"Modular Sampler\" width=\"460\" height=\"216\" class=\"alignnone size-large wp-image-2220\" /></a>\n\n<strong>SYNTH/SAMPLER</strong>\nThis is the basic sampler circuit above with some extra tricks to allow touch controlled modulation and a built tone generator to record and tweak. One of the coolest things about this version is the touch interface. Each pad is connected to a clock output from a divider. By touching the pitch base (the long strip below the touch pads) and any of the clock pads you can make very interesting rhythmic sequences. The divider can be synced to external gear, but I wanted to keep the circuit simple so there is no buffering. It will work with some (most) devices but not all.  \n<a href=\"http://casperelectronics.com/wp-content/uploads/Sampler_With_synth.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Sampler_With_synth-460x204.png\" alt=\"Sampler With Synth\" width=\"460\" height=\"204\" class=\"alignnone size-large wp-image-2222\" /></a>','Video #3: LoFi Sampler',0,'','inherit','closed','closed','','2177-autosave-v1','','','2016-12-29 11:01:52','2016-12-29 16:01:52','',2177,'http://casperelectronics.com/2016/07/15/2177-autosave-v1/',0,'revision','',0),(2216,2,'2016-07-17 18:07:03','2016-07-17 23:07:03','','Simple Sampler',0,'','inherit','open','closed','','simple-sampler','','','2016-07-17 18:07:03','2016-07-17 23:07:03','',2177,'http://casperelectronics.com/wp-content/uploads/Simple-Sampler.png',0,'attachment','image/png',0),(2198,2,'2016-07-15 08:08:18','2016-07-15 13:08:18','','Basic Sampler W Line In',0,'','inherit','open','closed','','basic-sampler-w-line-in','','','2016-07-15 08:08:18','2016-07-15 13:08:18','',2177,'http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in.jpg',0,'attachment','image/jpeg',0),(2199,2,'2016-07-15 08:59:55','2016-07-15 13:59:55','<iframe width=\"450\" height=\"240\" src=\"https://www.youtube.com/embed/ECSYLTB_sbw\" frameborder=\"0\" allowfullscreen></iframe>\r\nThis is part three of a three part series on DIY synth building.

And I\'m happy to find that the chip is quite flexible allowing wide pitch control range and modulation options (touch control, CV control, light sensors, potentiometers), and some interesting amplitude control options.  \r\n\r\n<strong>\r\nCircuit details:</strong>\r\n<strong>PITCH CONTROL-</strong> There are several ways to adjust the pitch of this chip. In this schematic I show one of the simplest methods that requires minimal parts and gives you a very wide pitch sweep. R14 determines the low range of the pitch and using 470k gives you about as low a pitch as possible. If you want a higher base pitch, increase this value. \r\n<strong>RECORD BUTTON-</strong> Pressing this button will record as long as the button is pressed/until the buffer is full. The length of the recording buffer depends on the overall pitch. At lower pitch the recording time is much longer but the quality is also much lower. C5 on the record button helps \"debounce\" the signal and minimizes false triggers. The record input can become quite finicky once you start adjusting the pitch above and below \"normal\" settings. The debouncing cap won\'t fix it but it will help. \r\n<strong>PLAY BUTTONS-</strong> \"play gate\" and \"play trig\" are two different inputs to play the sample. \"play gate\" will play the sample as long as the input to that pin is high (5 volts) \"play trig\" will run the sample for its duration as soon as it receives 5 volts at the pin, regardless of how long the pulse is. Both are useful but I primarily use the \"play trig\" input. \r\n<strong>REC/SAMPLE END LED-</strong> This light is on while the chip is in record mode. It ALSO will flash briefly at the end of playing back a sample. R8 determines the brightness of the LED.  \r\n<strong>LOOP SWITCH-</strong> The loop switch connects the output of the LED pin to the \"play trig\" input. That means that at the end of the sample the light will flash. This pulse will also retrigger the sample...making a looper. \r\n<strong> FEED THROUGH SWITCH-</STRONG> Setting this pin high passes the input signal to the output but along the way it goes through the ISD1820 IC and is filtered. The Filter cut is determined by the pitch setting. Therefore with a wide pitch range you are able to achieve a nice low pass filter. I go over this in more detail <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/voice-recorder-based-voltage-controlled-filter/\">here</a>\r\n\r\n<strong>MIC-</strong> You can use any ol electret mic for this circuit. R4,R5,C3 & C4 power and decouple the mic input so it works. \r\n<strong>SIGNAL IN-</strong> R1,R2, R3 and C1 buffer and attenuate an external signal. Its necessary to dramatically lower most signals to avoid strong clipping. Use lower value resistors on the input for quieter signals (computer, etc) and higher value for louder ones (modular synth, etc). \r\n<strong>HEADPHONE OUT-</strong> C10, R6 and R7 make up an output buffer and dual mono signal splitter. This allow you to connect the mono signal from the ISD1820 to a stereo headphone jack. This can also be done by simply connecting the signal to the left and right lugs of the jack. The problem with this is that plugging a <strong>mono</strong> cable into a stereo jack shorts the left output to ground. So if the signal is connected directly to left and right it will work with headphones but if you plug in a mono jack it will short out the audio signal and you will get no output. The two resistors solve this issue. \r\nBUT adding these means you can\'t add the speaker in series with the jack (common configuration that lets you use the jack as a speaker switch). To do this you can use the schematic below. The downside of this is that you will only get the signal in the right ear of your headphones. \r\n\r\n\r\n            <em>mono output with in-line speaker</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/speaker.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/speaker-460x237.png\" alt=\"Speaker\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2201\" /></a>\r\n\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in-460x540.jpg\" alt=\"Basic Sampler W Line In\" width=\"460\" height=\"540\" class=\"alignnone size-large wp-image-2198\" /></a>\r\n\r\nADDING MORE PITCH CONTROL\r\n\r\nOne of the best things about this chip is how easy it is to modulate the pitch.

An unexpected feature from a cheap lil\' voice recording chip :)  I\'ve put info on that <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/voice-recorder-based-voltage-controlled-filter/\">here</a>.\r\n\r\n\r\nFor this project you will need:\r\n\r\n-<a href=\"https://www.ee.iitb.ac.in/uma/~wel/wel12/Components%20Records/digital%20ic%20datasheet/cd40106.pdf\">CD40106</a> Schmitt trigger IC\r\n-<a href=\"http://www.intersil.com/content/dam/Intersil/documents/cd40/cd4020bms-24bms-40bms.pdf\">CD4040</a> Binary counter/clock divider IC\r\n-<a href=\"http://www.tuxgraphics.org/npa/outdoor-doorbell/ISD1800_datasheet.pdf\">ISD1820</a> Voice recording IC.

I\'ve added:\r\n-extended range on the pitch control \r\n-line in \r\n-stereo headphone output \r\n\r\n\r\n             <em>basic ISD1820 circuit</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler-460x326.png\" alt=\"Simple Sampler\" width=\"460\" height=\"326\" class=\"alignnone size-large wp-image-2200\" /></a>\r\n\r\n<strong>ISD1820</strong>\r\nFirst a note about the ISD1820. This is not a \"good\" sampler chip... The sound quality is bad, there\'s a moment of silence when the sample loops and, most annoyingly, it clicks when the sample starts. These things can\'t really be avoided (with the exception of the clicking which can be addressed with some fancy/maybe not worth it/ footwork). But despite all this I have found it to be genuinely fun to play with and depending on what you are recording, it can actually be a pretty useful little sampler. Furthermore, this is as cheap and simple as DIY samplers get. I would say this is about as simple as audio circuits in general get, which counts for something. And I\'m happy to find that the chip is quite flexible allowing wide pitch control range and modulation options (touch control, CV control, light sensors, potentiometers), and some interesting amplitude control options.  \r\n\r\n<strong>\r\nCircuit details:</strong>\r\n<strong>PITCH CONTROL-</strong> There are several ways to adjust the pitch of this chip. In this schematic I show one of the simplest methods that requires minimal parts and gives you a very wide pitch sweep. R14 determines the low range of the pitch and using 470k gives you about as low a pitch as possible. If you want a higher base pitch, increase this value. \r\n<strong>RECORD BUTTON-</strong> Pressing this button will record as long as the button is pressed/until the buffer is full. The length of the recording buffer depends on the overall pitch. At lower pitch the recording time is much longer but the quality is also much lower. C5 on the record button helps \"debounce\" the signal and minimizes false triggers. The record input can become quite finicky once you start adjusting the pitch above and below \"normal\" settings. The debouncing cap won\'t fix it but it will help. \r\n<strong>PLAY BUTTONS-</strong> \"play gate\" and \"play trig\" are two different inputs to play the sample. \"play gate\" will play the sample as long as the input to that pin is high (5 volts) \"play trig\" will run the sample for its duration as soon as it receives 5 volts at the pin, regardless of how long the pulse is. Both are useful but I primarily use the \"play trig\" input. \r\n<strong>REC/SAMPLE END LED-</strong> This light is on while the chip is in record mode. It ALSO will flash briefly at the end of playing back a sample. R8 determines the brightness of the LED.  \r\n<strong>LOOP SWITCH-</strong> The loop switch connects the output of the LED pin to the \"play trig\" input.

I\'ve added:\r\n-extended range on the pitch control \r\n-line in \r\n-stereo headphone output \r\n\r\n\r\n             <em>basic ISD1820 circuit</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler-460x326.png\" alt=\"Simple Sampler\" width=\"460\" height=\"326\" class=\"alignnone size-large wp-image-2200\" /></a>\r\n\r\n<strong>ISD1820</strong>\r\nFirst a note about the ISD1820. This is not a \"good\" sampler chip... The sound quality is bad, there\'s a moment of silence when the sample loops and, most annoyingly, it clicks when the sample starts. These things can\'t really be avoided (with the exception of the clicking which can be addressed with some fancy/maybe not worth it/ footwork). But despite all this I have found it to be genuinely fun to play with and depending on what you are recording, it can actually be a pretty useful little sampler. Furthermore, this is as cheap and simple as DIY samplers get. I would say this is about as simple as audio circuits in general get, which counts for something. And I\'m happy to find that the chip is quite flexible allowing wide pitch control range and modulation options (touch control, CV control, light sensors, potentiometers), and some interesting amplitude control options.  \r\n\r\n<strong>\r\nCircuit details:</strong>\r\n<strong>PITCH CONTROL-</strong> There are several ways to adjust the pitch of this chip. In this schematic I show one of the simplest methods that requires minimal parts and gives you a very wide pitch sweep. R14 determines the low range of the pitch and using 470k gives you about as low a pitch as possible. If you want a higher base pitch, increase this value. \r\n<strong>RECORD BUTTON-</strong> Pressing this button will record as long as the button is pressed/until the buffer is full. The length of the recording buffer is between around one second and over a minute depending on the pitch setting (The chip is rated at \"regular\" pitch settings to be between 8 and 20 seconds). At lower pitch the recording time is much longer but the quality is also much lower. C5 on the record button helps \"debounce\" the signal and minimizes false triggers. The record input can become quite finicky once you start adjusting the pitch above and below \"normal\" settings. The debouncing cap won\'t fix it but it will help. \r\n<strong>PLAY BUTTONS-</strong> \"play gate\" and \"play trig\" are two different inputs to play the sample. \"play gate\" will play the sample as long as the input to that pin is high (5 volts) \"play trig\" will run the sample for its duration as soon as it receives 5 volts at the pin, regardless of how long the pulse is. Both are useful but I primarily use the \"play trig\" input. \r\n<strong>REC/SAMPLE END LED-</strong> This light is on while the chip is in record mode. It ALSO will flash briefly at the end of playing back a sample. R8 determines the brightness of the LED.  \r\n<strong>LOOP SWITCH-</strong> The loop switch connects the output of the LED pin to the \"play trig\" input. That means that at the end of the sample the light will flash.

This is not a \"good\" sampler chip... The sound quality is bad, there\'s a moment of silence when the sample loops and, most annoyingly, it clicks when the sample starts. These things can\'t really be avoided (with the exception of the clicking which can be addressed with some fancy/maybe not worth it/ footwork). But despite all this I have found it to be genuinely fun to play with and depending on what you are recording, it can actually be a pretty useful little sampler. Furthermore, this is as cheap and simple as DIY samplers get. I would say this is about as simple as audio circuits in general get, which counts for something. And I\'m happy to find that the chip is quite flexible allowing wide pitch control range and modulation options (touch control, CV control, light sensors, potentiometers), and some interesting amplitude control options.  \r\n\r\n<strong>\r\nCircuit details:</strong>\r\n<strong>PITCH CONTROL-</strong> There are several ways to adjust the pitch of this chip. In this schematic I show one of the simplest methods that requires minimal parts and gives you a very wide pitch sweep. R14 determines the low range of the pitch and using 470k gives you about as low a pitch as possible. If you want a higher base pitch, increase this value. \r\n<strong>RECORD BUTTON-</strong> Pressing this button will record as long as the button is pressed/until the buffer is full. The length of the recording buffer is dependent on the pitch setting and is rated between 8 and 20 seconds under \"normal\" settings. At lower pitch the recording time is much longer but the quality is also much lower. C5 on the record button helps \"debounce\" the signal and minimizes false triggers. The record input can become quite finicky once you start adjusting the pitch above and below \"normal\" settings. The debouncing cap won\'t fix it but it will help. \r\n<strong>PLAY BUTTONS-</strong> \"play gate\" and \"play trig\" are two different inputs to play the sample. \"play gate\" will play the sample as long as the input to that pin is high (5 volts) \"play trig\" will run the sample for its duration as soon as it receives 5 volts at the pin, regardless of how long the pulse is. Both are useful but I primarily use the \"play trig\" input. \r\n<strong>REC/SAMPLE END LED-</strong> This light is on while the chip is in record mode. It ALSO will flash briefly at the end of playing back a sample. R8 determines the brightness of the LED.  \r\n<strong>LOOP SWITCH-</strong> The loop switch connects the output of the LED pin to the \"play trig\" input. That means that at the end of the sample the light will flash. This pulse will also retrigger the sample...making a looper. \r\n<strong> FEED THROUGH SWITCH-</STRONG> Setting this pin high passes the input signal to the output but along the way it goes through the ISD1820 IC and is filtered. The Filter cut is determined by the pitch setting. Therefore with a wide pitch range you are able to achieve a nice low pass filter.

R4,R5,C3 & C4 power and decouple the mic input so it works. \r\n<strong>SIGNAL IN-</strong> R1,R2, R3 and C1 buffer and attenuate an external signal. Its necessary to dramatically lower most signals to avoid strong clipping. Use lower value resistors on the input for quieter signals (computer, etc) and higher value for louder ones (modular synth, etc). \r\n<strong>HEADPHONE OUT-</strong> C10, R6 and R7 make up an output buffer and dual mono signal splitter. This allow you to connect the mono signal from the ISD1820 to a stereo headphone jack. This can also be done by simply connecting the signal to the left and right lugs of the jack.

I\'ve added:\r\n-extended range on the pitch control \r\n-line in \r\n-stereo headphone output \r\n\r\n\r\n             <em>basic ISD1820 circuit</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploa<a href=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler-200x142.png\" alt=\"Simple Sampler\" width=\"200\" height=\"142\" class=\"alignnone size-medium wp-image-2216\" /></a>\r\n\r\n<strong>ISD1820</strong>\r\nFirst a note about the ISD1820. This is not a \"good\" sampler chip... The sound quality is bad, there\'s a moment of silence when the sample loops and, most annoyingly, it clicks when the sample starts. These things can\'t really be avoided. But despite all this I have found it to be genuinely fun to play with and depending on what you are recording, it can actually be a pretty useful little sampler. Furthermore, this is as cheap and simple as DIY samplers get. I would say this is about as simple as audio circuits in general get, which counts for something. And I\'m happy to find that the chip is quite flexible allowing wide pitch control range and modulation options (touch control, CV control, light sensors, potentiometers), and some interesting amplitude control options.  \r\n\r\n<strong>\r\nCircuit details:</strong>\r\nNOTE ABOUT BUTTONS! all buttons in this circuit connect a pin on the isd1820 to +5 volts. This is also called setting the pin high. This can be achieved with the button as shown but also with various voltage generators, sequencers, gate dividers etc. \r\n\r\n<strong>PITCH CONTROL-</strong> There are several ways to adjust the pitch of this chip. In this schematic I show one of the simplest methods that requires minimal parts and gives you a very wide pitch sweep. R14 determines the low range of the pitch and using 470k gives you about as low a pitch as possible. If you want a higher base pitch, increase this value. \r\n<strong>RECORD BUTTON-</strong> The chip will record as long as the record input pin is high and until the buffer is full. The length of the recording buffer is dependent on the pitch setting and is rated between 8 and 20 seconds under \"normal\" settings. At lower pitch the recording time is much longer but the quality is also much lower. \r\nThe record feature starts to malfunction at high and low pitch settings! It\'s best to do your recording at a middle pitch setting. \r\nC5 on the record button helps \"debounce\" the signal and minimizes false triggers. \r\n \r\n<strong>PLAY BUTTONS-</strong>  \"play gate\" and \"play trig\" are two different inputs to play the sample. \"play gate\" will play the sample as long as the input to that pin is high (5 volts) \"play trig\" will run the sample for its duration as soon as it receives 5 volts at the pin, regardless of how long the pulse is. Both are useful but I primarily use the \"play trig\" input. \r\n<strong>REC/SAMPLE END LED-</strong> This light is on while the chip is in record mode. It ALSO will flash briefly at the end of playing back a sample. \r\nR8 determines the brightness of the LED.  \r\n<strong>LOOP SWITCH-</strong> The loop switch connects the output of the LED pin to the \"play trig\" input. That means that at the end of the sample the light will flash. This pulse will also retrigger the sample...making a loop. \r\n<strong> FEED THROUGH SWITCH-</STRONG> Setting this pin high passes the input signal to the output but along the way it goes through the chip and is filtered. The Filter cut is determined by the pitch setting. Therefore with a wide pitch range you are able to achieve a nice low pass filter. I go over this in more detail <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/voice-recorder-based-voltage-controlled-filter/\">here</a>\r\n\r\n<strong>MIC-</strong> You can use any ol electret mic for this circuit. \r\nR4,R5,C3 & C4 power and decouple the mic input so it works. \r\n<strong>SIGNAL IN-</strong> R1,R2, R3 and C1 buffer and attenuate an external signal. It\'s necessary to dramatically lower most signals to avoid strong clipping. Use lower value resistors on the input for quieter signals (computer, etc) and higher value for louder ones (modular synth, etc). \r\n<strong>HEADPHONE OUT-</strong> C10, R6 and R7 make up an output buffer and dual mono signal splitter. This allow you to connect the mono signal from the ISD1820 to a stereo headphone jack. This can also be done by simply connecting the signal to the left and right lugs of the jack. The problem with this is that plugging a <strong>mono</strong> cable into a stereo jack shorts the left output to ground. So if the signal is connected directly to left and right it will work with headphones but if you plug in a mono jack it will short out the audio signal and you will get no output. The two resistors solve this issue. \r\nBUT adding these means you can\'t add the speaker in series with the jack (common configuration that lets you use the jack as a speaker switch). To do this you can use the schematic below. The downside of this is that you will only get the signal in the right ear of your headphones. \r\n\r\n\r\n            <em>mono output with in-line speaker</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/speaker.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/speaker-460x237.png\" alt=\"Speaker\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2201\" /></a>\r\n\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in-460x540.jpg\" alt=\"Basic Sampler W Line In\" width=\"460\" height=\"540\" class=\"alignnone size-large wp-image-2198\" /></a>\r\n\r\n\r\n\r\n<strong>ADDING MORE PITCH CONTROL</strong>\r\n\r\n The ROSC in pin is intended to be connected to ground through a resistor to set the pitch. <a href=\"http://casperelectronics.com/wp-content/uploads/ROSCchart.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/ROSCchart-200x79.jpg\" alt=\"ROSCchart\" width=\"200\" height=\"79\" class=\"alignnone size-medium wp-image-2210\" /></a>\r\nThat resistor can be easily be replaced or used in parallel with touch and/or light sensors to control the pitch.  \r\nIt\'s possible to provide a very wide pitch sweep by connecting ROSC to a voltage divider between +&- as shown in the drawing below.\r\n\r\n<em>pitch control potentiometer</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/pitch-control.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/pitch-control-460x237.png\" alt=\"Pitch Control\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2207\" /></a>\r\n','Video #3: LoFi Sampler',0,'','inherit','closed','closed','','2177-revision-v1','','','2016-07-17 18:07:58','2016-07-17 23:07:58','',2177,'http://casperelectronics.com/2016/07/17/2177-revision-v1/',0,'revision','',0),(2220,2,'2016-07-17 18:19:18','2016-07-17 23:19:18','','Modular Sampler',0,'','inherit','open','closed','','modular-sampler','','','2016-07-17 18:19:18','2016-07-17 23:19:18','',2177,'http://casperelectronics.com/wp-content/uploads/Modular-Sampler.png',0,'attachment','image/png',0),(2222,2,'2016-07-17 18:25:56','2016-07-17 23:25:56','','Sampler With Synth',0,'','inherit','open','closed','','sampler_with_synth','','','2016-07-17 18:25:56','2016-07-17 23:25:56','',2177,'http://casperelectronics.com/wp-content/uploads/Sampler_With_synth.png',0,'attachment','image/png',0),(2223,2,'2016-07-17 18:28:01','2016-07-17 23:28:01','<iframe width=\"450\" height=\"240\" src=\"https://www.youtube.com/embed/ECSYLTB_sbw\" frameborder=\"0\" allowfullscreen></iframe>\r\nThis is part three of a three part series on DIY synth building.

I\'ve added:\r\n-extended range on the pitch control \r\n-line in \r\n-stereo headphone output \r\n\r\n\r\n             <em>basic ISD1820 circuit</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Simple-Sampler-460x326.png\" alt=\"Simple Sampler\" width=\"460\" height=\"326\" class=\"alignnone size-large wp-image-2216\" /></a>\r\n\r\n<strong>ISD1820</strong>\r\nFirst a note about the ISD1820. This is not a \"good\" sampler chip... The sound quality is bad, there\'s a moment of silence when the sample loops and, most annoyingly, it clicks when the sample starts. These things can\'t really be avoided. But despite all this I have found it to be genuinely fun to play with and depending on what you are recording, it can actually be a pretty useful little sampler. Furthermore, this is as cheap and simple as DIY samplers get. I would say this is about as simple as audio circuits in general get, which counts for something. And I\'m happy to find that the chip is quite flexible allowing wide pitch control range and modulation options (touch control, CV control, light sensors, potentiometers), and some interesting amplitude control options.  \r\n\r\n<strong>\r\nCircuit details:</strong>\r\nNOTE ABOUT BUTTONS! all buttons in this circuit connect a pin on the isd1820 to +5 volts. This is also called setting the pin high. This can be achieved with the button as shown but also with various voltage generators, sequencers, gate dividers etc. \r\n\r\n<strong>PITCH CONTROL-</strong> There are several ways to adjust the pitch of this chip. In this schematic I show one of the simplest methods that requires minimal parts and gives you a very wide pitch sweep. R14 determines the low range of the pitch and using 470k gives you about as low a pitch as possible. If you want a higher base pitch, increase this value. \r\n<strong>RECORD BUTTON-</strong> The chip will record as long as the record input pin is high and until the buffer is full. The length of the recording buffer is dependent on the pitch setting and is rated between 8 and 20 seconds under \"normal\" settings. At lower pitch the recording time is much longer but the quality is also much lower. \r\nThe record feature starts to malfunction at high and low pitch settings! It\'s best to do your recording at a middle pitch setting. \r\nC5 on the record button helps \"debounce\" the signal and minimizes false triggers. \r\n \r\n<strong>PLAY BUTTONS-</strong>  \"play gate\" and \"play trig\" are two different inputs to play the sample. \"play gate\" will play the sample as long as the input to that pin is high (5 volts) \"play trig\" will run the sample for its duration as soon as it receives 5 volts at the pin, regardless of how long the pulse is. Both are useful but I primarily use the \"play trig\" input. \r\n<strong>REC/SAMPLE END LED-</strong> This light is on while the chip is in record mode. It ALSO will flash briefly at the end of playing back a sample. \r\nR8 determines the brightness of the LED.  \r\n<strong>LOOP SWITCH-</strong> The loop switch connects the output of the LED pin to the \"play trig\" input. That means that at the end of the sample the light will flash. This pulse will also retrigger the sample...making a loop. \r\n<strong> FEED THROUGH SWITCH-</STRONG> Setting this pin high passes the input signal to the output but along the way it goes through the chip and is filtered. The Filter cut is determined by the pitch setting. Therefore with a wide pitch range you are able to achieve a nice low pass filter. I go over this in more detail <a href=\"http://casperelectronics.com/finished-pieces/omsynth-minilab/omsynth-video-tutorials/voice-recorder-based-voltage-controlled-filter/\">here</a>\r\n\r\n<strong>MIC-</strong> You can use any ol electret mic for this circuit. \r\nR4,R5,C3 & C4 power and decouple the mic input so it works. \r\n<strong>SIGNAL IN-</strong> R1,R2, R3, R9 and C1 buffer and attenuate an external signal. It\'s necessary to dramatically lower most signals to avoid strong clipping. Use lower value resistors on the input for quieter signals (computer, etc) and higher value for louder ones (modular synth, etc). \r\n<strong>HEADPHONE OUT-</strong> C10, R6 and R7 make up an output buffer and dual mono signal splitter. This allow you to connect the mono signal from the ISD1820 to a stereo headphone jack. This can also be done by simply connecting the signal to the left and right lugs of the jack. The problem with this is that plugging a <strong>mono</strong> cable into a stereo jack shorts the left output to ground. So if the signal is connected directly to left and right it will work with headphones but if you plug in a mono jack it will short out the audio signal and you will get no output. The two resistors solve this issue. \r\nBUT adding these means you can\'t add the speaker in series with the jack (common configuration that lets you use the jack as a speaker switch). To do this you can use the schematic below. The downside of this is that you will only get the signal in the right ear of your headphones. \r\n\r\n\r\n            <em>mono output with in-line speaker</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/speaker.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/speaker-460x237.png\" alt=\"Speaker\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2201\" /></a>\r\n\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in-460x540.jpg\" alt=\"Basic Sampler W Line In\" width=\"460\" height=\"540\" class=\"alignnone size-large wp-image-2198\" /></a>\r\n\r\n\r\n\r\n<strong>ADDING MORE PITCH CONTROL</strong>\r\n\r\n The ROSC in pin is intended to be connected to ground through a resistor to set the pitch. <a href=\"http://casperelectronics.com/wp-content/uploads/ROSCchart.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/ROSCchart-200x79.jpg\" alt=\"ROSCchart\" width=\"200\" height=\"79\" class=\"alignnone size-medium wp-image-2210\" /></a>\r\nThat resistor can be easily be replaced or used in parallel with touch and/or light sensors to control the pitch.  \r\nIt\'s possible to provide a very wide pitch sweep by connecting ROSC to a voltage divider between +&- as shown in the drawing below.\r\n\r\n<em>pitch control potentiometer</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/pitch-control.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/pitch-control-460x237.png\" alt=\"Pitch Control\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2207\" /></a>\r\n\r\nA CV input jack can be added as shown in the picture below. This allows you to interface with modular synthesizers and other electronics. \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/CVcontrol.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/CVcontrol-460x237.png\" alt=\"CVcontrol\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2219\" /></a>\r\n\r\n<strong>MODULAR SAMPLER</strong>\r\nAdd jacks to interface your sampler with a modular synth!\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Modular-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Modular-Sampler-460x216.png\" alt=\"Modular Sampler\" width=\"460\" height=\"216\" class=\"alignnone size-large wp-image-2220\" /></a>\r\n\r\n<strong>SYNTH/SAMPLER</strong>\r\nThis is the basic sampler circuit above with some extra tricks to allow touch controlled modulation and a built tone generator to record and tweak. One of the coolest things about this version is the touch interface. Each pad is connected to a clock output from a divider. By touching the pitch base (the long strip below the touch pads) and any of the clock pads you can make very interesting rhythmic sequences. The divider can be synced to external gear, but I wanted to keep the circuit simple so there is no buffering. It will work with some (most) devices but not all.  \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Sampler_With_synth.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Sampler_With_synth-460x204.png\" alt=\"Sampler With Synth\" width=\"460\" height=\"204\" class=\"alignnone size-large wp-image-2222\" /></a>\r\n','Video #3: LoFi Sampler',0,'','inherit','closed','closed','','2177-revision-v1','','','2016-07-17 18:29:30','2016-07-17 23:29:30','',2177,'http://casperelectronics.com/2016/07/17/2177-revision-v1/',0,'revision','',0),(2227,2,'2016-07-25 06:58:55','2016-07-25 11:58:55','','VCF',0,'','inherit','open','closed','','vcf','','','2016-07-25 06:58:55','2016-07-25 11:58:55','',2187,'http://casperelectronics.com/wp-content/uploads/VCF.png',0,'attachment','image/png',0),(2228,2,'2016-07-25 07:20:33','2016-07-25 12:20:33','The ISD1820 voice recording IC is a simple, relatively low quality voice recorder.

The downside of this is that you will only get the signal in the right ear of your headphones. \r\n\r\n\r\n            <em>mono output with in-line speaker</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/speaker.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/speaker-460x237.png\" alt=\"Speaker\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2201\" /></a>\r\n\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/basic-sampler-w-line-in-460x540.jpg\" alt=\"Basic Sampler W Line In\" width=\"460\" height=\"540\" class=\"alignnone size-large wp-image-2198\" /></a>\r\n\r\n\r\n\r\n<strong>ADDING MORE PITCH CONTROL</strong>\r\n\r\n The ROSC in pin is intended to be connected to ground through a resistor to set the pitch. <a href=\"http://casperelectronics.com/wp-content/uploads/ROSCchart.jpg\"><img src=\"http://casperelectronics.com/wp-content/uploads/ROSCchart-200x79.jpg\" alt=\"ROSCchart\" width=\"200\" height=\"79\" class=\"alignnone size-medium wp-image-2210\" /></a>\r\nThat resistor can be easily be replaced or used in parallel with touch and/or light sensors to control the pitch.  \r\nIt\'s possible to provide a very wide pitch sweep by connecting ROSC to a voltage divider between +&- as shown in the drawing below.\r\n\r\n<em>pitch control potentiometer</em>\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/pitch-control.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/pitch-control-460x237.png\" alt=\"Pitch Control\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2207\" /></a>\r\n\r\nA CV input jack can be added as shown in the picture below. This allows you to interface with modular synthesizers and other electronics. \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/CVcontrol.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/CVcontrol-460x237.png\" alt=\"CVcontrol\" width=\"460\" height=\"237\" class=\"alignnone size-large wp-image-2219\" /></a>\r\n\r\n<strong>MODULAR SAMPLER</strong>\r\nAdd jacks to interface your sampler with a modular synth!\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Modular-Sampler.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Modular-Sampler-460x216.png\" alt=\"Modular Sampler\" width=\"460\" height=\"216\" class=\"alignnone size-large wp-image-2220\" /></a>\r\n\r\n<strong>SYNTH/SAMPLER</strong>\r\nThis is the basic sampler circuit above with some extra tricks to allow touch controlled modulation and a built tone generator to record and tweak. One of the coolest things about this version is the touch interface. Each pad is connected to a clock output from a divider. By touching the pitch base (the long strip below the touch pads) and any of the clock pads you can make very interesting rhythmic sequences. The divider can be synced to external gear, but I wanted to keep the circuit simple so there is no buffering. It will work with some (most) devices but not all.  \r\n<a href=\"http://casperelectronics.com/wp-content/uploads/Sampler_With_synth.png\"><img src=\"http://casperelectronics.com/wp-content/uploads/Sampler_With_synth-460x204.png\" alt=\"Sampler With Synth\" width=\"460\" height=\"204\" class=\"alignnone size-large wp-image-2222\" /></a>','Video #3: LoFi Sampler',0,'','inherit','closed','closed','','2177-revision-v1','','','2016-07-25 14:56:21','2016-07-25 19:56:21','',2177,'http://casperelectronics.com/2016/07/25/2177-revision-v1/',0,'revision','',0),(2234,2,'2016-07-25 15:00:16','2016-07-25 20:00:16','This is the final part in a 3 part series I made with the support of <a href=\"http://wiki.ljudmila.org/Naslovnica\">Ljudmila</a>, <a href=\"http://www.projekt-atol.si\">Projekt ATOL</a>, and <a href=\"http://www.changingweathers.net\">Changing weathers</a> in Ljubljana Slovenia in the summer of 2015.

This can be a pattern of light, movement, electricity, even life cycles of organisms. The <a href=\"http://en.wikipedia.org/wiki/Oscillation\">wikipedia entry</a> gives dozens of examples of different kinds of oscillation.\r\n\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/casper/spacer1.jpg\"><img class=\"alignnone size-full wp-image-1302\" title=\"spacer\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/casper/spacer1.jpg\" width=\"460\" height=\"10\" /></a>\r\n\r\n<address> </address><address><em><span style=\"color: #33cccc;\">Figure 1. triangle oscillator</span></em></address>\r\n<ul>\r\n	<li><address><strong>The red line in fig 1 represents a voltage which goes up and down over a period of time. This is an oscillator.</strong></address></li>\r\n</ul>\r\nWhat we are most interested in is the oscillation (or modulating amplitude) of electricity. All of the electrically produced sound we hear is a repeating pattern of fluctuating electrical current.\r\nWhen this is applied to a speaker, the current activates a coil in the speaker which pushes the cone of the speaker away from or towards a fixed magnet. This action vibrates the air in front of the speaker which in turn vibrates the air in front of that and so on until those vibrations hit our ear drums and are perceived as sound. The sounds we hear around us are all incredibly complex patterns of air pressure modulation.\r\n<div>\r\n\r\nThere are three basic factors that make up all oscillators: <a name=\"frequency\"></a><strong>frequency</strong>, <strong>amplitude</strong> and <strong>wave shape</strong>. In musical terms we would call these <strong>pitch</strong>, <strong>volume</strong> and <strong>timbre</strong>. I will also talk a fair amount about <strong>phase </strong>which is relevant when working with multiple oscillators and plays an important role in creating drones.\r\n\r\n<hr />\r\n\r\n<ul>\r\n	<li>\r\n<h3><span style=\"color: #3366ff;\"><strong>Frequency</strong></span></h3>\r\n</li>\r\n</ul>\r\nOne complete sweep up and down is called a <strong>cycle</strong>. The number of cycles per second is your <strong>Frequency</strong> or <strong>Pitch</strong>.\r\n<strong>Frequency</strong> is commonly measured in <strong>Hertz</strong>, which is the number of cycles per second.\r\n<a name=\"amplitude\"></a><strong>Pitch</strong> is another term for frequency which is used <span style=\"text-decoration: underline;\">only</span> when referring to the frequency of an audio signal.\r\nFigure 1 shows a triangle wave with a cycle length of .5 seconds. The frequency of this wave would be determined by seeing how many cycles will occur in 1 second. In this case there are 2 complete cycles in 1 second. That means the wave has a frequency of 2 Hertz. This is well below the hearing range. Humans can hear oscillators between 20Hz and 20,000 Hz.\r\n\r\n<hr />\r\n\r\n<ul>\r\n	<li>\r\n<h3><span style=\"color: #3366ff;\"><strong>Amplitude</strong></span></h3>\r\n</li>\r\n</ul>\r\nAmplitude refers to the magnitude of voltage change across one cycle of an oscillation.\r\n<a name=\"waveshape\"></a>This in turn impacts the volume of the signal if it is sent to a speaker.\r\nThe image above shows a triangle wave with a positive peak of +5 volts and a negative peak of -5 volts. The amplitude is determined by figuring the absolute difference between these peaks. In this case that difference is 10 volts. This is commonly referred to as 10 Vpk-pk (10 volts peak to peak). There are many different ways to measure amplitude (pk-pk, RMS, Vp, etc…) but we’ll just be talking about Vpk-pk.\r\n\r\n<hr />\r\n\r\n<ul>\r\n	<li>\r\n<h3><span style=\"color: #3366ff;\"><strong>Wave shape</strong></span><a href=\"http://casperelectronics.com/wp-content/uploads/waveshapes.png\"><img class=\"alignright\" title=\"Waveshapes\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/waveshapes-200x160.png\" width=\"292\" height=\"233\" /></a></h3>\r\n</li>\r\n</ul>\r\nThe wave shape is the pattern of amplitude modulation over the course of a cycle. The waveforms in fig 2 are Sine, ramp, triangle and square.Sine, triangle and square are symmetrical waves. That means the positive and negative portions of each cycle are of the same duration. Many musical synthesizers offer other wave forms which are asymmetrical versions of these common waves such as ramp, saw and pulse waves.\r\n<p style=\"text-align: right;\"><span style=\"color: #33cccc;\"> Figure 2. Waveshapes </span></p>\r\nThe importance and impact of wave shape depends on its application. Many audio effects such as <strong>tremolo</strong> or <strong>phaser</strong> use low frequency oscillators (LFOs) to modulate certain parameters of the sound. It is commonly more desirable to use a sine or triangle wave for many of these effects such as the tremolo which\r\n<a name=\"review\"></a>fades the volume in and out. Using a square wave for this would create dramatic shifts in volume which can be unpleasant.\r\nMany natural sounds are synthesized using overlapping wave forms like those shown above. For instance a flute can be synthesized using several octaves of a sine wave. A horn on the other hand will use more square waves and maybe a triangle or saw wave. More advanced wave and synthesis theory sites the sine wave as the basis of all wave forms. It is shown how even square waves can be created by combining several sine waves.\r\n\r\n<hr />\r\n\r\n<ul>\r\n	<li>\r\n<h3><strong>Review</strong></h3>\r\n</li>\r\n</ul>\r\nThe basic components of an oscillator are:\r\n<h3><a name=\"1.2\"></a></h3>\r\n<ul>\r\n	<li><strong>Frequency</strong>.

Phase refers to a particular position in a <span style=\"text-decoration: underline;\">single cycle</span> of a wave (such as the positive or negative peak) and is measured in degrees. It is most commonly used to describe the relationship between multiple waves.\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/phasedegrees.jpg\"><img class=\"alignnone size-large wp-image-1643\" title=\"Phasedegrees\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/phasedegrees-460x236.jpg\" width=\"460\" height=\"236\" /></a>\r\n\r\n<span style=\"color: #33cccc;\">Figure 3. Phase</span>\r\nFig. 3 shows two sine waves (red &amp; blue) of identical amplitude and frequency. The green oscillator is the mix or <em>average</em> of the red and blue oscillators.\r\nPhase is measured in degrees with 360 degrees being one complete cycle. 180 degrees is exactly ½ of a cycle.\r\nIn fig. 3 the phase of the blue oscillator is offset at 45 degree increments from the red oscillator from left to right. With each step you’ll notice that the waves get farther apart and that the amplitude of the green (average) oscillator decreases.\r\n\r\nThis may seem confusing at first but it’s really quite simple. The green oscillator is the average of the red and blue oscillators.\r\nLet’s say the red and blue oscillators sweep from -5 to +5VDC (10Vp-p). Now look at the right most illustration of the 2 waves out of phase by 180 degrees. When the blue wave is at its positive peak (90 degrees) of +5 volts, the red wave is at it’s negative peak (270 degrees) of -5 volts.\r\nWhat is the average of -5 and +5? Zero. They are always going to be the opposites of each other so the average will always be zero. Now look at the 90 degree image. When Blue is at +5 volts/90 degrees, red is at 0 volts/zero degrees. The average of +5 and zero is 2.5 volts which means the green wave sweeps from +2.5 to -2.5 and is 5 Vpk-pk.\r\n\r\nThe important thing to take away from the info above is that the amplitude of an oscillator created by mixing two similar oscillators is <em>relative to the difference in phase</em> of the two source waves.\r\n\r\nIn fig. 3 the oscillators have identical frequencies. This means that the phase relationship once established will remain the same and the resulting averaged amplitude of the two waves will also remain the same.\r\n<strong>Q: What will happen if the frequencies of your two waves are NOT identical? </strong>\r\nWe established above that the amplitude of the averaged waveform is relative to the phase difference of the two wave forms, therefore as the phase difference of two waves increases and decreases so too will the averaged waveforms’ amplitude. What we have here is <strong>phase controlled amplitude modulation</strong> and the rate of phase modulation is controlled by the frequency difference between your two oscillators.\r\n\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/phaseModulation.jpg\"><img class=\"alignnone size-large wp-image-1644\" title=\"PhaseModulation\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/phaseModulation-460x202.jpg\" width=\"460\" height=\"202\" /></a><a href=\"http://casperelectronics.com/wp-content/uploads/phase_modulation2.jpg\"><img class=\"alignnone size-large wp-image-1645\" title=\"Phase Modulation2\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/phase_modulation2-460x220.jpg\" width=\"460\" height=\"220\" /></a><a name=\"sec2\"></a><span style=\"color: #33cccc;\">Figure 4. Phase controlled amplitude</span>\r\n<h3><a name=\"2.1\"></a></h3>\r\nIn fig. 4 the blue oscillator has a frequency of 10 Hz, the red is 11Hz. That means that it takes the red wave 1/10<sup>th</sup> of a second longer to complete a cycle than the blue wave. You can see that with each cycle the red wave lags a little bit further behind the blue wave which increases the phase difference between the two. As a result, the amplitude of the averaged wave (green) decreases as the phase offset approaches 180 degrees and then increases as it continues past 180 to 360 degrees.\r\n\r\n<hr />\r\n\r\n&nbsp;\r\n<h2 style=\"text-align: left;\"><span style=\"color: #3366ff;\"><strong>SECTION 2.

These are shown in fig. 5 and fig. 6.\r\n\r\n<a name=\"feedbackloops\"></a> They are very similar to one another but have been calibrated for different purposes.\r\n<strong>Osc 1</strong> is an audio frequency oscillator. It has a coarse and fine tune adjustment and only operates at audible frequencies.\r\n<strong>Osc 2</strong> is calibrated as a low frequency oscillator (LFO) with cycles as long as 2 minutes. It has a range switch and a single adjustment knob.\r\nOscillator 1 and 2 combine to make a square wave oscillator with a frequency controlled by oscillator 1 and pulse width modulation controlled by oscillator 2.\r\n\r\n<hr />\r\n\r\n<ul>\r\n	<li>\r\n<h3><span style=\"color: #3366ff;\"><strong style=\"color: #3366ff;\">Feedback loops</strong></span></h3>\r\n</li>\r\n</ul>\r\nThe oscillator circuit is a feedback loop between two op amps that are configured as a <strong>schmitt trigger</strong> and an <strong>inverting integrator</strong>.\r\nBasically an <em>integrator</em> turns square waves into triangle waves.\r\nA <em>Schmitt trigger</em> is a kind of comparator that turns modulating signals (like triangle waves) into square waves.\r\nThe key elements of the relationship between these two circuits is that they form a loop (Schmitt &gt; integrator &gt;Schmitt&gt;integrator&gt; etc…) and that the integrator is also an <strong>inverter</strong>. This creates a continuous cycle of modulation:\r\n1) Schmitt output goes HI.\r\n2) Integrator inverts Schmitt signal and outputs slope going down (LOW).\r\n3) When slope is near zero volts, Schmitt trigger is thrown and its’ output goes LOW.\r\n4) Integrator inverts and generates upward slope (HI).\r\n5) When integrator slope reaches peak, Schmitt trigger is thrown and output goes HI.\r\n<a name=\"rctimeconstant\"></a>6) etc……\r\nThis is an overly simplified explanation but enough for our purposes. Do more research on these valuable circuits once you are familiar with some of the basics of op-amps.\r\n\r\n<hr />\r\n\r\n<ul>\r\n	<li>\r\n<h3><span style=\"color: #3366ff;\"><strong>RC (resistor capacitor)time constant</strong></span></h3>\r\n</li>\r\n</ul>\r\nIn both oscillators (fig. 5 and 6) the primary element which defines frequency is the <strong>RC time constant</strong>. This relationship is a core component of most oscillators and is worth reading up on.\r\n\r\nThe RC time constant is a period of time defined by the relationship between a resistor and a capacitor.\r\nThe equation for this is simply <strong>t =</strong> <strong>R*C</strong>. In the case of the oscillators above it would be <strong>t=R1*C1</strong>.\r\nUnfortunately calculating the frequency of an oscillator is more complicated than just calculating your RC constant.\r\nIn many oscillators (including this one) there is a schmitt trigger component which watches the rising or sinking voltage from the integrator. The Schmitt trigger activates when the slope reaches predefined upper and lower limits. In order to determine the frequency of an oscillator we need to know what our upper and lower limits are and then calculate how long it takes our wave (the output of the integrator) to travel from one limit to the other.\r\nThese limits are determined by the relationship of 2 resistors in the schmitt stage. In fig 5 and 6 these are R2 and R3.\r\nThe equation for determining the duration of one cycle is\r\n(1/4R1C1)*(R3/R4)\r\nIn Oscillator 2 <strong>R</strong><strong>1</strong> is a 500k potentiometer in series with a 4.7k resistor between pins 8 and 13 of the two op amps. <strong>C</strong><strong>1</strong> is one of the three capacitors between pins 13 and 14 of the rightmost op amp. One of these caps is selected using a three way switch on the NovaDrone circuit board. This controls the frequency range of the LFO.\r\nLet’s say the pot is all the way up (full resistance) and the middle cap has been selected. The equations for RC and subsequently the frequency is:\r\n<strong>R1=504,700 Ohms</strong>\r\n<a name=\"howitworks\"></a><strong>C1= .000022 Farads</strong>\r\n<strong>R2 = 8,300 Ohms</strong>\r\n<strong>R3 = 10,000 Ohms</strong>\r\n<strong>Frequency in Hz = (1 / 4*R</strong><strong>1C</strong><strong>1) * (R</strong><strong>3/R</strong><strong>2)</strong>\r\n\r\n<hr />\r\n\r\n<ul>\r\n	<li>\r\n<h3><span style=\"color: #3366ff;\"><strong>How it works</strong></span></h3>\r\n</li>\r\n</ul>\r\nResistors limit the flow of current and capacitors store charge. Current flows through the resistor and is stored in the capacitor. The resistor controls how much current flows into the capacitor per second. Therefore the size of capacitor and the amount of resistance will determine how long it takes to fill the capacitor. A common analogy is to think about current flow as water, the resistor as a spigot\r\n<h3><a name=\"2.2\"></a></h3>\r\nand the capacitor as a cup. The more you open the spigot (reduce resistance), the more water (electrical current) will flow and the faster the cup will fill (capacitor will charge). The oscillator circuit is configured in a special way which causes the capacitor to continuously charge and discharge. It is looking for two states from the cap, fully charged or fully discharged. When the cap reaches either of these states, the whole circuit reverses polarity and the capacitors charge status begins moving toward the opposite state. The amount of time it takes to charge and discharge is your cycle duration.\r\n\r\n<hr />\r\n\r\n<h2 style=\"text-align: left;\"><span style=\"color: #3366ff;\"><strong>◊2.2 pulse width modulation (pwm)◊</strong></span></h2>\r\nPWM is exciting stuff….really! It is essentially a <strong>1 bit binary</strong> representation of an <strong>analog</strong> wave form.\r\nDigital wave forms only have 2 states, <strong>high</strong> and <strong>low</strong>. <strong>High</strong> is a voltage <em>at</em> or very close to the positive supply voltage. <strong>Low</strong> is a voltage <em>at</em> or very close to the negative supply voltage. It is basically just a square wave. Analog on the other hand is infinitely variable. Think about it like the difference between a light switch (digital) and a light dimmer (analog). PWM is a wave form that bridges the gap between these two formats. It can be used to make sound, control the brightness of an LED, control the speed of high torque motors and speak to microprocessors. It is also the language that a microprocessor will use to speak with the analog world.\r\nPulse Width (PW) refers to the relative durations of high and low voltage in a single <strong>cycle</strong> of a square wave.\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/pulsewidth.jpg\"><img class=\"alignnone size-large wp-image-1648\" title=\"Pulsewidth\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/pulsewidth-460x214.jpg\" width=\"460\" height=\"214\" /></a><span style=\"color: #33cccc;\">Figure 7. Pulse width</span>\r\nFig. 7 shows three square wave oscillators of the same amplitude and frequency but with differing <strong>pulse width</strong>. The red oscillator has a 10% pulse width. That means the wave goes high for 10 % of the duration of one cycle. The green wave is 50% and the purple wave is 90%. What is important to note is that pulse width has nothing to do with frequency and only refers to the relationship between the high and low swing of the wave.\r\n\r\n<hr />\r\n\r\n<ul>\r\n	<li>\r\n<h3><span style=\"color: #3366ff;\"><strong>The Comparator</strong></span></h3>\r\n</li>\r\n</ul>\r\nThe job of a comparator is simple. Two signals are fed into the “+â€ and “-“ inputs (labeled 10 and 9 in fig. 8 respectively). If the voltage at the “+â€ input is <em>higher</em> than the “-“ input the output of the comparator goes <strong>high</strong>.If the “+â€ input drops below the “-“ input the output goes <strong>low</strong>.\r\nIn the NovaDrone t<a href=\"http://casperelectronics.com/wp-content/uploads/comparator.jpg\"><img class=\"alignleft\" title=\"Comparator\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/comparator-200x76.jpg\" width=\"200\" height=\"76\" /></a>he triangle output of Osc 1 and Osc 2 combine through a simple comparator (fig. 8) to make a single square wave with a modulating pulse width. In this way, the comparator also functions as a pulse width modulation processor.\r\n\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/casper/spacer1.jpg\"><img class=\"alignnone size-full wp-image-1302\" title=\"spacer\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/casper/spacer1.jpg\" width=\"460\" height=\"10\" /></a>\r\n\r\n<span style=\"color: #33cccc;\">Figure 8.</span>\r\n\r\nFig. 9 below shows how two triangle waves are transformed through the comparator into a square wave with a modulating pulse width.\r\nThe blue triangle wave in fig. 9 is oscillator 1. The red triangle is osc 2. The green line is the combined PWM output.\r\nAny time the blue line (osc 1) is above the red line (osc 2), the green line (pwm) goes high. As the red line rises the percentage of each cycle that the blue line is above the red line decreases. This changing percentage is what makes our modulating pulse width effect.\r\n<a href=\"http://casperelectronics.com/wp-content/uploads/PWM3-copy.jpg\"><img class=\"alignnone size-large wp-image-1647\" title=\"PWM3 Copy\" alt=\"\" src=\"http://casperelectronics.com/wp-content/uploads/PWM3-copy-460x202.jpg\" width=\"460\" height=\"202\" /></a>\r\n\r\n<span style=\"color: #33cccc;\">\r\n</span>\r\n\r\n<a name=\"sec3\"></a>\r\n\r\n<span style=\"color: #33cccc;\">\r\n</span>\r\n\r\n<a name=\"mix\"></a><span style=\"color: #33cccc;\">Figure 9.

The amplitude is c\r\n\r\n<a name=\"led\"></a>\r\n\r\nalculated as RF/RI. In this case RF = 10,000 and RI = 100,000.

Failure to use a driver can result in something called a <strong>loading effect</strong> which basically means that the device being driven will affect the behavior of the rest of the circuit in bad ways, like the pitch changing when the lights turn on. The LED in the NovaDrone uses a lot of current relative to the rest of the circuit (90mA vs around 30mA for the rest of the circuit) therefore a driver is necessary. The key component of a driver is the <strong>transistor</strong>.

The double unit is essentially two NovaDrones on a single <a href=\"http://casperelectronics.com/wp-content/uploads/NovaDrone/store/doublePCB.lone_.better.jpg\">illustrated PCB</a>. The double unit shares a single power input and single audio output.

The input is diode and regulator protected so there\'s very little likelihood that the circuit will be damaged from plugging in the wrong power supply.\r\n\r\n\r\n<form target=\"paypal\" action=\"https://www.paypal.com/cgi-bin/webscr\" method=\"post\" >\r\n<input type=\"hidden\" name=\"cmd\" value=\"_s-xclick\">\r\n<input type=\"hidden\" name=\"encrypted\" value=\"-----BEGIN PKCS7-----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-----END PKCS7-----\r\n\">\r\n<input type=\"image\" src=\"https://www.paypalobjects.com/en_US/i/btn/btn_viewcart_SM.gif\" border=\"0\" name=\"submit\" alt=\"PayPal -
