The idea for AddOhms #8 has been around for quite some time. I’m always trying to find ways to explain why current limiting resistors are necessary. So while working in the shop one day, I decided to play with some LEDs and a bench-power supply. Then I decided to record what happens.
In fact, I shot all the lab video used here one day. Then about 3 weeks later, I got around to writing the script for this tutorial. Since the two were disconnected, you’ll probably notice a couple of jump cuts in the live action footage.
