Got my G-1 lens SWEET :p . Now im just waiting for my 12x sled in the mail. Thanks Jayrob

Ya i build my first Red laser with info on your site. Glad that your back :D

Stupid Australian Laser Laws.... Damn you customs nice lol

Thanks :D I just sent him a message about the part number.

:anyone:

Hi Bionic-Badger is there some thread you might know about where it tells you how to use LPF better. Thanks

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. 635nm - 650nm Three Element Glass Red Laser Lenses for Aixiz Module | eBay

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.

O never thought about that ether Bemwv. Quote by Benmwv - Doesn't the lm317 drop ~2.5-3v plus the 1.25v over the resistors?

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...

You sure because they say that you don't even want to touch the lens of the diode b/c of how fragile it is ?

That sucks. :cryyy: thanks

Hi this is my first post on LPF and I have know about this place for awhile and am so happy that there is a site so full of great info and kind people. Sorry if I ask any noobish things but I think I did my research. I have a laser I built awhile ago and works just fine. It is a 658nm laser...
