So I've been on this 2 year quest to build a blu ray laser into an altoids canister, and I did all my research and everything. My build so far is attached.
I'm using a dummy load as seen here all over the web: Laser Driver Set-up - OdicForce Lasers Online Shop
My driver is one of these (with voltage boost): 405nm 100 300mW Laser Diode Driver Reverse Protection | eBay
Now I've run into the problem of setting the current. I followed the instructions on the dummy load sites explicitly, and I'm finding that my driver gives me only 0.50mA, but testing over the resister as the instructions say, I get nothing: no voltage and no current. Here's the catch; the same driver that I just tested on the dummy load burned out a PHR803T diode on 1.5v at the same setting - probably 300mA. I know I saw another person on the forum with the same problem, but am I just an idiot, or does anyone know what my major malfunction is?
