I have dismantled an old DVDRW drive and taken a 4-pin laser diode from it.
After connecting it to two 2A batteries (red with positive, and blue with negative), the light beam is diverging, and the brightness is even dimmer than another laser diode that I got from a presentation pen.
Also, the it became hot within a few seconds that I can even smell the smell of the solder melting. Is there something that I should modify in the circuit to make it work properly?
(Sorry if I am asking in the wrong place)
