hey, im a 15 year old from chicago. i might be young (and therefore, inevitably noobish), but i do understand basic laser stuff from looking around on the forums. like building a driver, using diodes and heatsinks right, etc. im really interested in lasers. i have 5 and 50 mW greenies from DX, but theyre both around 40mW. im currently building a phr-803t and lpc-815 with lengths of pipe (i might be cheap but its working really well- the body helps with the heatsinking). if all goes as well as it has been, im looking at a minimalistic lpc-815 build for around $26. so yeah, thats what im into, building cheap powerful lasers. hi :D

COOL! what laser power meter did you use to find this out??

Don't forget to read the Newcomers Section and the Forum Rules...
I'm curious as to the LPM question in post #3 as well...
Enjoy your stay...:cool:

thanks guys!

i actually did not use an LPM, im just estimating. theyre about the same power, can both burn things but not light matches. based on non-true 50mWs having the possibility of a little under-spec and 5mW trues ALWAYS being overspec, im just throwing out a number. it could be 50mW. 30mW seems a little low to me though. anyway, i just got my diodes from modwerx :san:

You may have been lucky, I have a 67mW LEDshoppe 50mW laser that has trouble poping balloons, so depending on your beam size you may have lasers >50mW!

haha well i guess ledshoppe is pretty unpredictable. i bought a "50mW" laser from them that could not burn ANYTHING. just a little brighter than a normal red pointer. anyway, both my diodes worked perfectly. i wired an lpc-815 up with 3 10-ohm resistors and a 16V 100uF cap i found, using 3 AA batteries. it worked awesomely, and for the price of $30 a few of my friends want some :yh: this laser hobby is working out MUCH better than my high-voltage and/or aquarium hobbies... thanks for all the support!
