Hello LPF!
I am currently working on building my first laser. I know everything I need and what to. I'm using a PHR 803t, and another PHR 805. Aixis housing of course. Using a 9V power supply and purchasing a dummy load to set my current to 100-110mA. Only problem I am having is I cannot find a Rkstr adjustable driver anywhere that is in stock! Any suggestions to help find a site or another driver that works?

Thanks LPF!

Modwerx has a few Groove 2 drivers in stock. It's a linear driver like the rkcstr but only has a 1.2V dropout. :beer:

It will work great and no, it does;t come with wires but the guy who owns/runs that site is a LPF member and very nice. If you ask, I'm sure for a few extra dollars he will solder some lead wires on the driver for you.

The PHR diodes need ~6V and the driver needs 1.2V. With a 9V power supply that leaves you with ~1.8V left over which the driver will dissipate as heat. It should work fine with your set-up.
