DIY laser diode driver | Constant current source


GreatScottLab’s instructable on how to make your own constant current source and how to get a ‘burning’ laser diode:

In this project I will show you how I extracted a laser diode from a DVD Burner which should have the power to ignite a match. In order to power the diode correctly I will also demonstrate how I build a constant current source which delivers a precise and steady current to the load.

Check out the video after the break.
