UPDATE: It works! Here is a small video where I use another laser diode: https://youtu.be/DSwHNE-rjv4 Previous video: https://youtu.be/XCnI6ZOYKes Constant Current Load video: https://youtu.be/8uBcywBUTkw Facebook: https://www.facebook.com/greatscottlab Twitter: https://twitter.com/GreatScottLab Parts list, Schematic, PCB Layout is on instructables: http://www.instructables.com/id/DIY-Laser-Diode-Driver-Constant-Current-Source/ Facebook: https://www.facebook.com/greatscottlab Twitter: https://twitter.com/GreatScottLab Support me for more videos: https://www.patreon.com/GreatScott?ty=h Parts list (affiliate links): Aliexpress: 1x Laser Module: https://s.click.aliexpress.com/e/_dZlipG7 1x MCP602: https://s.click.aliexpress.com/e/_d7gXXAP 1x 3.3Ω / 5W Resistor: https://s.click.aliexpress.com/e/_dVdbbC3 1x Vero Board: https://s.click.aliexpress.com/e/_dWvCu9h 1x 1kΩ Resistor: https://s.click.aliexpress.com/e/_dYW3fCj 1x IRLZ44N N Channel MOSFET: https://s.click.aliexpress.com/e/_dSubBCb 2x Screw Terminal: https://s.click.aliexpress.com/e/_d8g2zdz 1x 500kΩ Potentiometer: https://s.click.aliexpress.com/e/_BfhVhtCx 1x Thermal Paste: https://s.click.aliexpress.com/e/_dViWRGj 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
