Adjustable Constant Current LASER Diode/LED driver
I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable. Laser diodes are harmful and...
