Oh, those are to much money right now......

You have 6 LPM's!, how much would you sell one for?:)

Would the 808nm be better at etching white paper than a 445nm? :tinfoil:

Thanks for your concern, but in comparison to a visible laser do they burn better?:thanks:

I want to here some people opinions on 9mm 1W 808nm laser diodes. Are they as good or better or worse at burning when compared to say a 1W 445nm laser? :beer:

Here is what i have for a driver idea, i don not have room for a lm317. And i do not know of any tested working pre-made drivers that are this small, my space available for a driver is only 1/4 deep by 1/2 round! And in order to find out my resistor value i kneed to know the diode forward...

Heres the ones i got. It say 2.2v @ 55ma 405nm 20mw CW Violet Laser Diode DIY/Lab/Study 2pcs/pak | eBay

the forward voltage drop a crossed the - & + pins ins that high? :wtf:

Hello, i bought this 2 pack of cheap 20mW blu ray diodes, but i do not know what the forward voltage drop is, in order for me to build my driver as small as i want i kneed to be able to know the forward voltage drop of the diode. They are 55ma @ 2.2v working current/voltage. I don't kneed exact...

Damnnnnn......:yabbmad:

Well exactly how much do you want for yours?:evil:

Sorry man i had no clue :yabbem: But i understand that shit gets in the way of hobby's, been there done that! lol :evil: I got work all weekend so ill have no time for my hobby's ether.

I'm curious, were did Styropyro find this laser at? i have looked all ove the internet for a 100mW 473nm and cannot find one! :cryyy:

Hey have you took pictures on how to make the heatsink? :undecided:

Thanks, and yea my shoulder was done at the end of this project, same with my back! :crackup: I didnt, but i shoulda taken a pic of the pile of shavings on the floor. :tinfoil: And yes i had saftey glasses on the whole time. :beer:
