Hi,
I'm relatively new to building lasers, but I've been messing around with an M140 diode for a while now, and decided to incorporate it into another project.
The idea was to have a driver connected to a standard latching switch, that when pressed would power the diode. Before soldering all...
Hello, I'm pretty new to building laser circuits (and relatively new to electronics in general), and I was wondering if anyone can tell me what to do with the "case pin" (third pin that isn't positive or negative) on a laser diode? I've already built 2 circuits, both of which worked (with...
