If I was smart enough I would buy a TON more and make a bunch of laser modules just to play with and sell to my friends. And just to think, each one of those babies could all turn into lasers worth a lot more than what we payed for them!

Okay, I have a quick question though. When you add a capacitor to the circuit, it gives the diode a slow "start up" so to speak, right? Well I've been using 6.3 volt 100uf capacitors, and I want to play around with pumping high ammounts of current through one of the diodes (like VaThInK on CPF does) with a heatsinked peliter to cool the module. So my question is, can I use a high capacitance capacitor (like 1000uf or more) to give a very slow ramp up to full current at around 500-800mA. I will probably use the AixiZ wall wart supply (supposedly regulated at 3.2 Volts @ 500mA) but if any of you guys know of a good power supply I'm open to suggestions. Unfortunately I can't afford a benchtop DC Power Supply so that's out of the question for now.
Thinking it over, it would probably be better to use a potentiometer, but I don't really want to have to fool with having to slowly turn the current up.
It sucks having a limited electronics knowledge. :'(
