Hello, this week my friend was cleaning out his workshop and I noticed he was throwing away several laser carriage. I asked if I could stay with them and he gave it to me but I found a problem, I do not know and he does not remember what each one is what, cd player, dvd player, cd burner, dvd burner ... In total there are 27 carriage, most with two diodes (The IR and the Red, I think), others just one.
How do I know which diode is from what? It has some detail on the circuit to help out? Or do I have to test all to know?
Out of curiosity I removed one of the diodes and used two AA alkaline to power on and it shines like a LED, using a 5mw laser lens I could adjust it to be infinite ... got about 7 meters (23 ft) but after reading a few topics I realized that I should never connect directly to a power source, but even he shine with the use of the lens, this means that the diode is dead? Or that I was lucky and he is only a DVD Player diode that does not shine more than that.
I'll make a "Laser driver - It Can Be done" but I could not find a 3.6v or 7.2v battery, what else could I use?Can I use a lower or higher voltage? This drive also works with the DVD Player diodes?
