I am new to this forum and was searching for similar threads so if I am posting a common question I apologize in advance.
I am looking for a good 50mw green laser , not pointer. One that will connect direct to 3 volts.
One question that I have,
I purchased a few 50mw green lasers off eBay from china , just the cylinder gold frame ones, and attached heat sinks to them. I connected them to 3v and worked great, but they have all burnt out or something (showing the red light from the inside) I looked in using my phones Camara to see that so I didn't look right at it.
One of the lasers , the negative wire fell off and I resoldered it and it wasn't working, only the red light. Another wasn't working right off the bat, and another burnt out within days.
Also the resister on it seemed to be getting extremely hot after only like 8 seconds of play. So hot I can't touch it.
Am I doing something wrong?
Or did I make the wrong decision purchasing these ?
Are they low quality?
Or do I need a special power supply to plug them in to?
(I was using a computer power supply's 3v lead for one of them and just a universal plug switched to 3v for the other 2)
I am sorry if these are ridiculous questions, I'm just stuck in a rut right now, I don't want to fork out more money till I know what I'm doing
