Update
Guys,
Just thought you might want to see the prototype controler (only two channels)
The 10K pot and reversing switch is connected via the 6-pin header infront of the power transistors. I've also left room for a small heatsink, but in tests so far these don't get hot enough to warrant one !
The only problem is I'm still waiting on some 16F676's as I fried the only one i had in the breadboard... (got distracted by a phone call and connected the +12v to the PIC rather than the +5v !!! - it was glowing and had to cut short the call to pull the plug !!) - Tested the output stage and it works fine so can't see any reason for it not to work when the PIC's arrive.
