So I recently built a LM317 circuit. So I was watching a video and well calculated that to get the required output current I built this.
Well the output was expected to be around 50mA and before setting it up to the diode it ran as expected.
So what we did (we as in my friend and I) discharged the capacitor and hooked it up to the laser diode. We ran the diode on 5v and it was dim. Guessing that it was too weak to run on 5v we hooked it up to a 12v power supply and nothing happened. So we then checked the output after removing the laser diode and we were getting 30v out! we had no amps coming out and well I'm guessing that the laser got fried, but yeah. I don't know. Anyone want to help me out?
