This is my first laser build which turned out to be complete success :)
Tutorial: How to build a laser

- Laser Diode - 300mW 650nm
- Laser Driver - Mohgasm 378mA
- Case - custom made out of old flashlight
- Heatsink - custom made out of copper pipes, not sure if its enough for longer periods of usage
- Power - currently using universal adapter 3 - 12 volts, never set it higher than 6v

I finally found matches after i made this video and indeed it CAN easily light matches, about 100-200ms time and lights the match from about 10 - 20cm when focused.
