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 !   Previous video:    • Electronic Basics #13: Coils / Inductors (...   Constant Current Load video:    • Li-Ion Capacity Test || DIY constant curre...   Facebook:   / greatscottlab   Twitter:   / greatscottlab   Parts list, Schematic, PCB Layout is on instructables: http://www.instructables.com/id/DIY-L...

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. Music: 2011 Lookalike by Bartlebeats
