@smurfboy266 the diodes are tiny! if you broke the pins it wont work. and usually the top pin is positive, the middle right pin is negative and the botton pin i cut off.

Components in my DIY burning laser assemblyby happyguy8226,073 views
what did you use for collimate the beam?
I've also built one, i pilot the laser diode with 300 mA, no problems found.
Sorry for bad english.

Well, in the video I used the outer lens of the DVD writer head. But you can find laser module, what you can use for collimator. This contains a little 650nm TO diode, that you can replace with your dvd writer diode.

i wanna know how voltage u use.. like 12v,3.6v,9v....
Cesarmtodoido 3 years ago
The laser diode must be drive by current generator, 16x writer diode needs about 200mA.
