We often need some low value resistors, less than 1 Ohm. Mostly as current sensing resistors in power electronics projects. You can’t measure less then 1 Ohm with cheap multimeters. […]
LM317 constant current source circuit design
A constant current source source can supply a fixed current to a load regardless of input voltage or load change. LM317 constant current source is one of the simplest design. […]
LM317 regulator board PCB making
LM317 is the most used and easily available adjustable voltage regulator. Here I’ve designed a simple PCB for the regulator with surrounding diodes, capacitors, resistors, etc. In this board, the […]
DIY LED driver for 5Watt LEDs, 12V strips from 100-240 VAC
I got many requests to provide guide to build simple 230V to 1,3,5 Watt LED driver in response to my simple led driver diagram. So, below I’m writing an article […]
