Introduction: DIY Make Led Driver for Laser or Led Diode
Led driver made of two componets LM317 regulator and one resistor,value of resistor is calculated by formula R=1.25/current you get the resistance of resistor for example in video I use 1.5ohms 2resistor in parralel each one is 3 ohms.
Watch the video how to make your own led driver
