I was looking through my bits and pieces for an LM7808 and not suprisingly I don't have one. 5 Volt, yes but no 8 Volt. I did however come accross an LM317 variable regulator. I also managed to find a 500 ohm and a 2700 ohm resistor to set the Vout to 8 Vdc. Has anybody here gone this route?
Thanks,
Rick

Just a quick update, The above circuit measures 8.1 VDC at the arduino with 12 VDC "jump starter / power pack" type of input.
Thanks for the info Rick,it presents an option I had not explored.
