I can't find anywhere the voltage you need for an LPC 826 diode, however I do know that it is 250mW. Does that mean that depending on the current I supply, I need to adjusts voltage so it does not go over 250mW? So say I want to give it 250mA of current, would I supply 1V? Thanks

Thanks, I'll try that now. If I use a 10ohm resistor will it have a higher or lower mA output?

Sorry, should be better now.

First off, I followed these two YouTube videos to make my laser: How To Build A Burning Red Laser Driver Circuit - YouTube Homemade 250mW Burning Red Laser - YouTube I made it to (what I think) is exactly how he made it (except for the casing). On the second link at 2:22 you can see the results...
