GreatScottLab’s instructable on how to make your own constant current source and how to get a ‘burning’ laser diode: In this project I will show you how I extracted a laser diode from a DVD Burner which should have the power to ignite a match. In order to power the diode correctly I will also […]

Simple LED driver/constant-current source 20 mA
Another Instructable by Jan Henrik, a constant-current source which gives 20mA at the output. He writes: It is a circuit, which limits the current to 20mA, what allows us to drive any normal led, without calculating a resistor, you can just plug the led in and see it emitting light… Also this allows us to test […]
