<p>Ok Casper, I will do it this weekend as soon as I finish my new synth breadboard system, a bit like your FX proto board. I need to post a pic it really turned out nice. It is one of those big powered breadboards with the two lcds to show voltage on positive and negative rails and the has a +5v then I added a long piece of L bent steel attached via Velcro to each side to match top height. Reason I used Velcro so was I can quick change the sides (sorta). Right now it has 10 1M pots, 10 10k pots (for my wave shaping 40106, 2 500k two 1k one of them log, a few other random pots, 10 push buttons, 10 toggles, 4 3.5mm jacks, 4 banana + 1 banana ground, 4 6.5 jacks (all jacks can be discreet or normalled to act as interfaces, it has 5 endless encoders, a small dip switch section with 2 8 switch dip switches to control sequencers, it had leds I got to add them back, 2 12 position rotary knobs, and then in front of the breadboard is a big etched copper contact plate with 41 contacts. I think thats it. I got to finish wiring some of the parts and come up with better harnesses for the pots so they stay out of way (right now I think I am going to make female pin headers to cable to male pin headers so i can remove them. I have then started making for the drone lab instructional pdfs (btw do you want it all in one pdf or a pdf per project?) these stackable breakout jacks for the main chips you remove chip from jack insert this breakout jack between and plug back in chip. This makes it where you do not have to do any soldering (well as little as possible) while messing with the bends/mods/whacko ideas. The only soldering I am having to do with this type of board is cutting the traces between the BO points and making a header in proto area to test different things.</p>
<p>The projects I was going to try to have done for the PDFs for you are the following (All Drone Lab specific):<br />
1. touch points for the drone lab.<br />
2. Adding patching jacks<br />
3. Adding CV control for (xyz)<br />
4. Using CMOS chips or op-amps whatever you have around to make multi waveform LFOs<br />
5. CMOS ring mod and ring mod cascades with the 4 drones<br />
6. CMOS sequencer for the new CVs you can have<br />
7. Fun with Vactrols<br />
8. Voltage starve with both pot and photoresistors<br />
9. Complex sounds part 1: CMOS cascaded 4093 with feedback<br />
10. Complex sounds part 2: modify mixer into phased mixer<br />
11. Complex sounds part 3: High quality distortion circuit + fuzz<br />
12. Input modifications: Tremelo, compressor/limiter, expander, gate and ducker, pitch tracker, envelope follower (all thee can be used with patches from internal oscillators also)<br />
13. Simple CMOS divider tricks: Oscillator sub harmonics, clock divider<br />
14. Complex sounds part 4: Turn the square waves for drones into complex waveforms (wavetable) with a single 4017 CMOS chips and 10 10k pots/sliders (sliders are cool for graphical waveform look)<br />
15. Complex sounds: (borrowing a idea from triwave)3 "colored" LFOs for each oscillator that has 4 depth knobs for each osc, a speed/pitch knob, symmetry knob and waveform knob. With this system I can also cross modulate each oscillator (without it sounding too noisy)</p>
<p>These sound quite difficult but all of them are silly easy as Casper suggested in the CMOS magic mod posting. Most of them require a single chip, sometimes they are a little more complex.</p>
<p>I have all the schematics for these 14 mod PDFs, I just need to take pictures of all of them breadboarded up so it makes a bit more sense, and I need to improve my writing skills a bit to put in step by step guides.</p>
<p>Hopefully I will get some done this weekend. Along with guides on how to "safely" get your Drone Lab prepared for this type of monkeying around.</p>
<p>Thanks<br />
