[sdiy] Minimoog clone

[Bryce Lanham]

Hi David,

I've been working on a miniclone on and off for 5 years, delayed
mostly because of school, then college. I am actually in the process
of finishing at this very moment.

I went the more authentic route, laying boards out in Eagle following
pictures of the original layouts, with someone on-list giving me the
dimensions. Tracked down the original AMP Duo-Tyne connectors and
pins, actual honest-to-god E402's, and stumbled across a cache of
Allen-Bradley Type J potentiometers. I may have found a solution for
the unobtanium UID rocker switches; I'll know more by next weekend.

My site, which needs to be updated badly, is here:
http://brycelanham.com/mediawi​ki/index.php/Minimoog_Clone. I can put
the Eagle files up if you want. The parts info is more current on
Joe's site, I missed the 2n4058's at MCM and my supplier for rev-log
potentiometers is no longer around. Pictures are here:

I have the power supply board working on my desk, and am trying to
rebuild my oscillator board harness to check if that board still
works.

I have a CAD model of the mini, thanks to list member Tim Parkhurst,
but I'm not that good at using AutoCAD, and the model is missing all
of the inner front-panel mounting screw and potentiometer-stop holes.
Anyone have pictures of a Mini with its' front panel removed? I
finally gained access to a metal shear and break, and figured I might
as well go full-out and completely copy the original case.

The keyboard is also giving me a bit of trouble. I have an old organ I
could cannibalize, but I 'm also considering cannibilizing a cheap
midi keyboard and using a microcontroller to interface it to the
original keyboard circuitry.

Bryce
