Ya I'm kind of new to this place, i really didn't know it was 2 months old. Is there some thread you might know about where it tells you how to use LPF better. Thanks Bionic-Badger
Here's a link for a 3 element red glass lens. I don't know if it's better or worse than a g1/g2 lens. But i think its better than a acrylic lens for sure.

I'm considering in getting this diode for my laser I'm building.
405nm 300mW blu-ray laser diode 6x blu-ray diode sled | eBay
Do you think it will really putout 300mW at 320mA ? Has anyone tried one of these diodes ? Also whats a good way to find/test the mW power of this laser when its done...
Hi I just have these two qusetion about the lm317. First is the voltage drop and the voltage need by the regulator the same thing ? Also does the 317 use 2.5~3v for both constant current regulating and voltage regulating.
thanks you guys
Sorry this thread is not important anymore.
Questions...
Ok i think i'm getting this but i have just a few other questions. First is the voltage drop and the voltage need by the regulator the same thing ? Also does the 317 use 2.5~3v for both constant current regulating and voltage regulating.
thanks you guys
Wait i think i got this one if theres a 1.25v drop across the resistors and if the Vdrop is close 1.2 for the 317 than thats 2.5 and with the Vdrop is not perfect in every 317 thats 3v. :) i could be wrong.
So 1.2v is used by the 317 in voltage regulation mode and close to 3v for current mode Oceansoul ? I thought it was only 1.2 and not 3 for the 317, i did not think about that it is not being used for voltage regulation. Also so voltage drop and how much the 317 uses is the same thing.
OK i have been trying to figure this out for at lease 4 hours straight and its driving me nuts ! :banghead: How is it that for a red laser you need a power supply of 7.2 when the diode needs 3, 1.2 for long life between battery changes and the lm317's dropout voltage is 1.2. Thats only 5.4...
