<p>hi,</p>
<p>thanks ghostwizard for making such a fun kit! i couldn't help but stay up late the past few nights, soldering to my heart's content. the instructions were crystal clear and everything worked perfectly from the get go, with the exception of one cold solder joint that was a bit tricky to find. in the end, visual inspection proved to be a better diagnostic tool than my trusty multimeter.</p>
<p>i tried to build my own four-voice drone synthesizer about a year ago, but the end result didn't sound nearly this good. each oscillator worked well on its own but not all four at the same time. must have had something to do with the value of the capacitors i used for the mixer. so thanks for all of the prototyping and hard work in picking the perfect RC combinations! </p>
<p>i have two corrections to the materials list from http://casperelectronics.com/drone-lab-parts/</p>
<p>-- 3 of the 1N4001 diodes are needed, instead of 1.<br />
-- LM7809 voltage regulator is not listed in the diode section.</p>
<p>regarding the housing, i haven't yet figured out why we need 14 nuts. i use 7 for the corners, sides and center and 3 for the battery box. am i missing anything? also, what is the preferred positioning of the lock washers? between the vinyl spacer and pcb? </p>
<p>thanks again! i've been working off headphones and i can't wait to hear this thing at full blast on my monitors.</p>
<p>kind regards,<br />
