Description
I ran quite a few workshops around 2008-10 – UK, Germany, Portugal, Spain, Norway, Netherlands..
Everyone got to build their own board-synth to introduce to electronics & soldering.
It was really like a Weevil but without the quasi-ringmod.
Here are some archive documents:
Main instruction documentaion
Supplement – schematic, BOM, etc
WOM Pro details

There is also a thread with many details/comments here at the MW forum.
