I love the LM317 for my lasers, but its kinda difficult to cope with the 5 volts and up rule so it works.
Is there any current regulating driver you can make to use 3 volts? Cause the aixiz modules and lots of pen lasers only use 3 volts and they still regulate the output.
Anyone know how those pen laser drivers work?
