  • I found a short between the input and ground pins of the 7805 chip on the backside of the circuit board. I cut the short between the pins, and saw a significant improvement in the resistance measurements. I replaced the 7805 and all appears to be fine (at least the green power LED light operates) with the 9 VDC adapter input.

  • My PicAxe Development board arrived today. When attempting to power the board, the supply voltage drops from 5 Volts to about 0.3 Volts. This happened when using the 3 “AA” battery set and using a 9 Volt regulated power supply. Measuring the resistance across the 5 Volt input pins on the board shows a resistance of 0.2 ohms with nothing connected to the board.
    Any suggestions?

No public wish lists :(
