Everything I had read thus far told me that I needed a circuit which supplied a constant current to the laser diode. It would have been easier if I could have just connected the laser diode to my DC power supply and adjusted the voltage, but that would have been too easy.
By the way, this is part 2 of a two part series on this project. If you missed part 1, you can review it here. Continue reading “Do-It-Yourself Blu-Ray Laser Pointer (Part 2)”
