I'm planning to build it in an stainless steel "sanwu pocket" style host with a 12mm axis module and want to overdrive it to 250mw instead of its 185mw raiting ,my question is , do these diodes run hot? I would assume not since is an single mode Same question for the 405nm bdr-206 ,I will run...

I tried the driver without the resistors and if you use it with a good li ion battery the capps will fry(250ma before it died) if you use it with 2 AA batteries it works just fine outputs something like 180ma with out any resistors .My driver came with a 2k ohms resistor wich outputs about...

And what current does it output at 6-7v? On AliExpress says it outputs 0.95A at 6V wich is way too much ,or does the driver give the necessary voltage to the diode and you can fully regulate the current between 0 and 2A? Planning on using this driver on some other builds And can I use a single...

I know it's late again but ,I build the laser and it works but I think the small round driver overheats ,it is at full power for 10-15s and then it gets dim and starts pulsating, and is wired because the sharp 488nm is not powerfull diode How did you wired that driver?

I can't share link ,but search for 520nm laser diode driver(it's a round driver coin like size) or zonah on AliExpress he is the seller ,

Hello I know it's late to reply, but I have found the same driver on AliExpress and the seller says thet the default current is 120ma, did you remove any resistors to reach 280ma? I want to build a laser with sharp 488nm diode

Found chip code , LM358

It has 3r3 chip on it witch I know is pretty good I can't share links because I don't have 20 posts yet but in the descripsion says one li ion battery

The driver imput is 3.7V ,but I don't know the max amps imput or it dosen't matter?

I want to build a blue 1.6W 445nm laser(OSRAM PLTB450B) with a boost driver . I have some high discharge li-ion witch puts out 20A(samsung 25r) will this fry/kill everything?

What housing is best for laser pointer ? Can I use a cheap flashlight as housing? And what batteries to use for sharp gh0637aa2g?

Thanks ,you saved me a lot of time

Went on ebay and found a bdr-209 405nm diode with heatsink and housing. The diode max current is 500mA , but the driver has a potentiometer that goes from 0-800mA ,is this a big problem? Can I leave the potentiometer in the middle setting?

I looked on sanwu lasers at the new rangers series and can't decide witch one to by(the green option is 60 dollars more expensive),all I know is that the 405nm has a far more better divergence than the green one(I think that they are using an dpss diode) but the green one is far more vizible to...
