HACKED!: Laser Diode from DVD Burner || Constant Current Source

UPDATE: It works! Here is a small video where I use another laser diode:    • Laser Diode from DVD Burner ignites a match !

In this episode of HACKED! 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.
