I decided to wire up my own power supply after doing a quick search. My power is cap...

This is a really simple but very handy circuit which will provide both a positive and a negative voltage from a single rail power supply. This circuit was originally from a fairly ol...

I have made many 9V Power supplies. but this is the simplest. Check out my facebook fan page: ElectroPCBJared for other schematics and PCB layouts.
