[Afroman] contacted us to share his new video on the LM317. The humble LM317 adjustable voltage regulator is everywhere. From wifi routers, to high spec lab equipment. Given a noisy input and a ...

The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its ...

This project is made out of few junkbox parts and builds a useful constant current load for switch mode power supply, battery testing, and other applications. A dummy load is traditionally a big ...

This constant resistance dummy load has not yet been tested in the real world. [YS] was inspired to come up with the circuit after reading Wednesday’s Re:load dummy load post. That was a constant ...
