PCBs for MegaDrum

I've now converted schematics for MegaDrum32 Digital
Board and Analogue Board. The rest of the schematics will be converted
later. The whole purpose of this conversion was to create PCBs for
MegaDrum. On the Schematics page you can now
download PCBs in DipTrace format. This is my first attempt at
PCBs and the may not look ideal. But now you can download schematics in
editable format and can create your own versions of

Changes to Analogue board

I have just come back from my holiday so I'm
resuming my work on the project. First, I was advised to add 100 Ohm resistors
on the 4051 inputs to protect it from static electricity. I've updated the
Analogue Board schematics accordingly. I should mention that my test Analogue
Board is running fine without those resistors but to be on a safe side I'd
recommend to use them when you build your Analogue Board.
