Hey John, Thanks for the offer and I'll let you know. I just spent a load of cash on a backrest mold that came out wrong. If you know microchip and have worked with their ICD2 I would have you take a look at some code. I'm having trouble coding a dsPIC to control an h-bridge for a cold-plate design.
