So I have a 3.3v buck voltage regulator that is rated at 800ma. I am wondering if this is the appropriate setup as i have done a little digging online and tried the lm317 with different resistors setup one with a single resistor and another with 2 resistors. both times i tried this the beam was almost nonexistent. i was using dvrrw diodes that i scavenged from a couple old laptops. One of the diodes is still functional but i burnt out the others. So i bought the lpc diode from aliexpress and hooked it up with a 1uf ceramic cap on the ground and the input pins. I am using a lithium battery 3.7v to push the power and i noticed i was able to focus it enough to burn the leather on my couch by accident, but it stays cool and doesnt get hot at all. This is leading me to believe that it is under powered. I see its rated for 300mw, which I guess i dont have a full grasp on the driver build concept yet but am getting confused big time on how to maximize the lasers output but also not fry the damn thing. Any help would be much appreciated. Also I bought one of those freak blue lasers that look like a gatlin gun from amazon and noticed it burns paper if you hold it still for a little bit. I was able to focus the beam a little bit finer by disolving the thread locker that was on it and spinning the lense out a little further. There is a very long chamber of threads on this unit and the diode ais deep within this. I am curious if there is some kind of lense focusing ability left in this but dont know what to do. Thank you guys in advance. I have been geeking out on styro pyros videos.
