    IH Breakout Board

    I have one of the first IH machines. Breakout board for servos fried. Apparently Bob Campbell who supplied the original boards is no longer active. Does anyone have a source for a replacement board?

    Re: IH Breakout Board

    which BOB do you have ?

    if you can post photos and a link to the data sheet
    I expect the closest alternative could be a BOB from the likes of CNC4PC
    and a couple of power supplies mounted on a chassis the size of Bob Campbell's BOB
    and made into a drop in replacement


    if you lived in the UK I could of looked at it to see if its repairable
    provided the PCB tracks and any programmed PIC or Atmel chip are OK

    PS

    I am thinking of something like CNC4PC's C11S and separate power supplies
