Help | 1W + 445nm Laser Build

Hi,

Not long ago I have purchased a new 2W 445 m140 diode from DTR, and guidesman host and BenBoost 1.256 amp driver from cajunlasers.

The problem is the driver. I have read about the voltage spikes and I don't know what to do next ? ... Use the BenBoost ? ... or Buy a new 1.5 amp microboost from DTR ? ...

I have also saw the thread about the BenBoost but I can't wait till they test it again.

Please help me to decide

Thanks in advance ! ,
Eitan.

just use an LM317 regulator

The BenBoost "issue" has been resolved just stack more caps to get around 22uf capacitance or replace them with 22uf capacitors

Also I doubt the spike would kill an M-140 at 1.256Amps so I say your good to go on with your build enjoy :beer:

I'm not very electronical... I also have a benboost, would a 47uF electrolytic capacitor bridging the diode leads be okay?

Thanks man !!

No problem

It would definetly help but that's not the output cap, the output cap is the one on the top left of the PCB, but that cap on the output would help a lot :beer:
