This is my first post so please don't hate on it.
Anyways, I just bought 2 250mW and 2 20mW 650nm Red Laser Diodes. The 250mW only cost 8 dollars and the 20mW cost 3 dollars each. I also bought along with it 2 Aixiz kits with the driver circuit and everything. That is the good thing about living in China, despite the pollution and and traffic you can get 3 watt pre assembled lasers for aprox. 113$ I bet it would be great business illegally importing these to the US. XD
Anyway this is my first time doing DIY laser assembly so any tips anyone can give me will be great. I really don't want my diodes to die on me. I have a question; how do you calibrate the driver circuit to power the laser at 250mW, not too low or too high. As I said I really don't want to burn out the diodes.
Also I would like some tips and ideas on what to do with it. Ideas for science projects or burning stuff. For burning stuff I would like to know what 250mW can burn. Can it set a match on fire or pop a balloon? I would like to know the spectrum of burning for a 250mW Red Laser
One last thing, I wonder how much I can push the 250mW diode with it still have a decent lifespan? 300mW, 350mW, 500mW?
