Doepfer

Well if there is more interest I could consider to build some of them (after
I have included the 12V -> 5V solution), I guess it cost me some 40 Euro's
(components only), of which the 10 chassis parts (in/out connectors) are the
most expensive (I paid 1,5 Euro each).

but I can certainly make a short description of this building project an
include a schematic, it is really quite simple
in what format would this be preferred and at what location should I store
it ?

nb: I thought there was some sort of DIY section on the Yahoo A100 site, but
couldn't find it....anybody knows more ?
