Hey guys, I really know nothing about these 2 crystals or how they work. All I know is that they can turn an 808nm beam to 535nm which is what I need for a product I am designing. I am wondering if anyone knows of any sources where I would be able to obtain these crystals in bulk and possibly...

so just hook up the ammeter between the first diode and +ve and turn the dial on the driver until I get 2.3a on the ammeter? because i dont have any 1ohm diodes. I have a pot but the lowest resistance I can set it to is 4ohms

Hey guys. I feel like an idiot for posting this because i'm sure it has been posted a million times. I can't seem to find instructions on how to make a testload for my driver. I have a 9mm 445nm diode and the blitzbuck v3.1 driver. The driver is adjustable and I want to set it to 2.3a please...

oh the irony. lol

Hey guys, I am hoping to use this LED to make a really powerful IR remote. So I need to power it with 1.7v @ 2a. Does anyone know of a good driver to accomplish this? Also, I will be using a PICAXE microprocessor to control it. I am wondering if I should have the transistor pulsing the led on...

do you have a suggestion as to how I should power it? How many ma and v should I power it with? Also, wondering how I should arrange the circuit with the driver and microprossessor. Should I just put a transistor in series with laser diode to turn it on and off the output of the driver? or...

I was thinking of not even using the lens. I might have confused you with the title "long range". I simply want to use a laser diode without a lense as it is more powerfull than an IR led

Hey guys, I am wanting to make a long range remote for my tesla coil. I have tried radio frequency transmitter/receivers but of course the tesla coil interfiers with them so while I would be able to turn the coil on, it wouldnt turn off... So I guess my only other option is IR. I have made an...

hi, i made a typical M140 445nm 2w handheld laser powered by a mohgasm 1.8a driver. for some reason the burning power of the laser seems to be weakening. I know its not the batteries, because I have been using a steady power supply from time to time, and i notice a difference. It could also be...

Hey, I need to charge my cr123a batteries any way possible really quickly because i am leaving for vacation soon and want to use my laser. Unfotunatly my old charger fried. I tried making one before but one of the batteries ended up exploding (literally), so ive come to you guys first this...

Hey, I dont know much about batteries, so i need some help. I have a laser housing which can hold two cr123a batteries (or the lr123a batteries that im using). Unfortunately they only supply a max of 4v (8v together) and i need atleast 9v for my laser to run at 100%. Are there any other...

when do you think you'll stop selling assembled drivers? I think i'll need like 20 or something soon, but I'm not 100% sure and i need a week or two to find out. It would be alot better if they were assembled.

i better order a crap load of them then, I plan on making a whole bunch of lasers and selling them over the summer

I made a 2w 445nm laser... what class is it? i need a really fancy, but accurate name for my laser. i think its class 4 laser.. so something like "high intensity class 4 laser" thanks :)

a very strange thing happened today. Moh, my batteries finally came, and that was the reason i wasnt getting full power. The driver heated up alot like expected. But then, after about 10 seconds after i would turn it on each time, the laser would flash like a strobe light. Maybe 5 flashes per...

yeah those are what im using. two in series. and the power sucks. it can barely burn stuff and the driver barely gets warm after long use.

i bought this diode off of DTR (1.5-2w 445nm) is it broken??? It barely burns anything. powered with the mohgasm 1.8a driver and 2 cr123a's (6v)

nope it was $15 Laser Heat Sink module,fits 445nm 2w diode and more | eBay

results: 2w 445nm laser test - YouTube and it will soon be all cosy in a really cool flashlight :)

and it worked nicely :)
