LM317T Voltage Regulator with Pass Transistor

Hi all. I decided to make this guide because I couldn't seem to find one already made on youtube. I made this guide really simple for a really simple kind of person. There is also a schematic at the end. And then another simpler schematic for beginners. This driver can be used for Red laser diodes and Blu-ray laser diodes. Good luck!
