I've been a lurker for awhile, and just started messing around with these myself. Here's my question. I'm wanting to power 7 5mw red laser diodes using a 5VDC 1Amp adapter I have laying around. What resistor do I need to use in front of each laser to feed them 35mA each, to keep from frying them? The diodes are cheapies I ordered from DX.
