The Weird Sound Generator has been a fun project and Music From Outer Space website has a wealth of information about Synth DIY. I ordered the PCB from MFOS, it arrived quickly and the project was easy to put together and worked as advertised. Thanks to Ray Wilson for being generous and sharing his considerable efforts with the rest of us!
Be careful with the soldering iron. I burned by thumb and index finger by grabbing the hot end.
I had about half the parts and ordered the other half from Jameco. The Jameco website and catalog are easy to use and the service was good.
The value-pro pots I got from Jameco are still really stiff after a fair bit of use. I got the 1M pots from the Ax-man surplus in St. Paul and they are smooth as silk. I got three one-hundred foot spools of wire from the Ax-man for $2, two of the spools were OK and the third was total crap as the core kept breaking during construction.
I decided to use a Lexan for the main panel instead of Aluminum as recommended. I could not find a good source for eighth inch Aluminum sheet. When I build my Sound Lab Mimi-Synth Plus I am defiantly going to use Aluminum. You can not cut Lexan with out special equipment and I had to ground all the pot bodies independently.
I did one slight modification: I cut a board trace and added an extra switch to turn off Voice B. The wires I used to connect the controls to the board are way too long for my case and are something of a tangled rats nest. Ray Wilson points out that the wires connecting the filter controls are susceptible to capacitive coupling. So I turn off Voice B and I can still hear a ghost of it on the output. Lesson learned: be neat about the panel wiring.
