Now you can add the power supply of your choice and you should have a working device! I hope you think the result was worth the effort.
I showed a completed disk to some friends just before Christmas, holding it at the top of their tree. They asked if I could make one that looks like...
One of the points of designing this device was to make it "hackable." I've provided the source code so that you can both learn how these things are p...
Here is the design documentation. I've included the schematic as a high-res image and the complete set of Gerber files in a ZIP package.
