Re: Blue Destroyer ( 2 W 445nm )
Here's my solution to 12V and 1.8A:

You will need to solder a 0.50 Ohm resistor on top of the 0.20 Ohm sense resistor. That will give you around 1.75A. I've built several...
Since you are new to lasers, and since this is a thread dedicated to 12X 405nm diodes, never mind the vice - get a suitable pair of safety glasses/goggles.
Also, I wouldn't recommend using thermal glue for that purpose.
It could, and may very well be, more than one thing.
If you want to try and find out, then start my measuring the sense resistor - it should be 0.2 Ohms. If you can't measure the resistance for one reason or another then try to measure the voltage across the sense resistor while the circuit is...
Re: The "Blue Ninja" - 445nm DIY Creation
rhd, I use that driver in all of my 445 and 405 builds. I made my own boost and/or buck drivers until I found this one for $1.99. I've used at least 6 or 7 of these and have yet to have one fail.
I modify the sense resistor to output from 300mA up...
Re: SF-BW512L 12x BR sled GB *CLOSED* *NOW TAKING PAYMENTS*
And I don't like other people paying for my hobby :shhh:. Especially since you've done the leg-work.
Count me in for an equal portion of the losses. If I'm the only one, then it's $25 each ;).
I'm not sure from your post if you've verified that the diode current is 1A, with the 10440s and the pot to max. If you did, then do you have sufficient heat sinking? And if 1A only gives you 630mW from a cold start with sufficient heat sinking, then it might just be a low efficiency diode...

qumefox, I tried to pay but I got this message from PayPal:

Not sure what to do....?
Re: FS: Optotronics 150mw Pen
HiGrade, it's not your place to tell others how seriously they should take this forum - remember, some member's livelihood (in whole or in part) comes from this forum. For myself, I have a passion for lasers that has to compete for time against my...
