Power supply

[Derek Jewett]

I have been working on something simular to what you're doing... and so far
all I have thought of is using an LM317 voltage regulator that regulates
the voltage, and using a 7805 regulator to split off a  +5v supply... But
you still need a -5v supply along with ground to make it work..
