i recently bought a 304 100mw green from sanwu and it was the longer one of the 3. note the 304 actually is a 303 but binned by sanwu (at least thats what i think i got. mine is marked with YT-303. dont have an LPM to test)

Thanks all! this laser sure is bright!! Compared to a NUBM07E its about the same if not a little brighter maybe. I also find the color more pleasing vs a 532nm.

Last week my long awaited NDG7475 diode arrived from DTR. I also had ordered a heatsink for a C2 host from Eudaimonium. The quality was really really nice. The C2 i ordered was originally black but i de-anodized it. This makes the host a lot more attractive in my opinion. I had to drill out...

Thanks! sure do. Ill send you the money when i get some money on my paypal!

yeah i tried to make my own 17mm blank board by stripping a 105c Led driver. but the problem is at the inside of the pill. there is e thick lip at the inside of the pill for the 17mm board to rest on. this makes it that the nanoboost just fits. its literally scraping the sides at all 4 corners...

I did it has been a long time since i build a laser from scratch. But i guess its part off the hobby :) Yeah i saw them but the price is pretty steep and shippingcosts to belgium doubles the price. Those als also buck drivers and i wanted to be able to use this laser with just one 18650.

I just need to get this of my chest. scroll down for TL;DR So my first of 2 shipments from DTR arrived today. It was the 209 x16 405nm diode in 20mm module with a nano boost driver. I was going to put it inside a Convoy s2+ host. but this whole build just went so wrong. Murphys law struck...

Im looking for a NUBM07E or NDB7675 handheld laser from someone in the EU. Can someone help me out with this? Thanks in advance!! Dentillozie

sucks to hear that! arent the lpc-836 and lpc-840 almost the same? i think is read some thread about the 840 not being much more performant then the 836.

Thanks! It was a great build to do. I had some real fun doing this one.

My 660nm laser broke down so i decided to rebuild it into a more powerfull 638nm laser. https://youtu.be/J5Hvonmgfoc link: https://youtu.be/J5Hvonmgfoc Diode used was a Oclaro 700mw @ 1.14A. I dont have a LMP but im guessing it puts out about 900mW I hope you like the video! Thanks for...

Okay thanks man :)

thanks man! tell me master, whats my next quest :p p.s.: i did the payment for the red laser, i don't know if u saw it already. :)

hello guys i know a c6 build is nothing new but i just wanted to share my pride. this is my first real build (made a dvd burner laser in the past without driver, still held up for a year or so) let's talk about specs: host: aurora cree c6. battery: 2x 18350 1200mah ultrafire driver: 1.25A...

nice build man congrats!!

awesome build :) i love the look of that host

Depents on the current you want it to be driven, most dvd burner diodes are driven at 250mA. 1.25v / 0.25A = 5 ohm. The best way to get this is by taking 2 times a 10ohm resistor in parallel. This wil give you 5ohm. Make sure you got a proper heatsink to cool your diode :) Good luck

here are some macro pictures of a red laser diode from a DVD burner (the diode was LED thats why i decaned it) hope u liked it, i know the quality ist that great but it was the best i could do :) -DenTilloZie

what current do u suggest?

thanks man! i think im going to do the same as you, it will make the cost of my project alot lower if i use the DX driver :p if you dont screw the pill all the way dont you have problems with the heatsink?
