[sdiy] EFM SBM

[Sean Ellis]

I built a huge cabinet with one of these at the core. Be very wary that the 
circuit layout was not great! I got hum in every module and it took a lot of 
work to get it working correctly. Make sure you re-run all the ground 
signals in a star pattern from each module to the power supply. After doing 
that I could start making music with it.

If you're curious I think I have some photos of the cabinet I built scanned 
but in a sad and tragic disaster I lost both all of my hard copies of every 
circuit I had done, and my entire collection of electronic schematics and 
layouts. Imagine losing 4 years worth of circuit designs and completely 
irreplaceable hard copies :-( I dont know if I can go back to DIY now, am 
just gutted.....
