[sdiy] Single buss keyboard controller PCBs available

[Ray Wilson]

That's not an amateur question at all. You could probably put the current 
source to the bottom of the buss and the ground to the top and then use some 
op amps to invert and offset the resulting control voltage so that it would 
be right side up again. I have not tried that but it seems plausible. If I 
were you I would breadboard the whole schmeer before buying any boards 
though :-)

Cheers

Ray
