Ok, another question. I have a +9v DC power supply, and I'm using a 7805
to get +5v for the circuit. But I need -5v as well, and I can't seem to
find anything to create that. The 7905 needs a -ve input voltage, and I
don't have one to give it. A few people have suggested other
semiconductors, but the electronics places near me don't carry them. So
any suggestions?
