Here is some final documentation of my building process.
Testing the circuit:
My first prototype was made of scrap 3/4 plywood. I used the CNC Router to do a test cut of my gears. The rest was thrown together with any available wood and screws.
Moving on from the prototype I designed a two level box to house my coils. The coils themselves remained in their packaging. I soldered the leads to wire and cut acrylic tubes to size and added rubber end stoppers to house the neodymium magnets.
After staining the wood to a walnut color and drilling holes for all my wire I gave my box a tolex covering:
The synthesizer circuit consists of 3 integrated circuits (IC) in series.
Using the CNC I cut my pedal, baseboard, and under pedal connectors from 1/2 inch plywood. I put sleeve bearings through all bores that house moving parts, and shaft collars to help keep moving parts in alignment.
Watch it go!
