schematics and PCBs (except ft232 USB board) are now in DipTrace format.
Off course you can modify the PCBs to your liking using free version of
DipTrace. Also check out this
version of PCB contributed by BlueDragon. It combines
MegaDrum32 Digital Board and AVR-CDC USB interface in one
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
Updated documentation section to include information about
installing USB drivers. Also added AVR-CDC firwmare in the downloads section.
MegaDrum Configuration guide with SysEx messages
section. I just added a preliminary version of MegaDrum Configuration
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.
I'm away on holiday for two weeks from tomorrow. I won't update
this site during this time (there is still a lot to add in the doc/faq section)
but I'll try to answer questions.
MegaDrum is made public.
