Introduction: DIY Make Led Driver for Laser or Led Diode

About: My name is marjancho and I love electronics,makeing gadgets,hack and pranks.

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

Nice one


Resistors in parallel don't add up. Only series resistors add together. right now you are using an equivalent resistance of .75 ohms.

Yeah I realized that later. The way I read it and the way it was pictured threw me off. I had a fail moment but he is indeed correct.

Great video, I found it very helpful thank you.
