Previously, we looked at resistor voltage dividers. Sometimes I get questions about using these instead of regulators. In this video, I show why that doesn’t work. In fact, I go one step further and show that Zener regulators do not work either.

Video Switching regulators make use of the energy storage properties of capacitors and inductors. A transistor, or switch, controls the charging and discharging. This method makes for an efficient regulator but can be difficult to design. Show Notes Here are links to the products mentioned in AddOhms #18: LM3671 Buck Controller from Texas Instruments LM3671 Breakout board from Adafruit PowerBoost 1000 (boost converter) from Adafruit VERTER (buck-boost converter) from Adafruit These are articles related to…

https://youtu.be/81zNcctopBI What was the first electronic component you played with? It was probably a LED. They’re fun to blink in patterns or learn to fade. Most projects (and products) use them for useful indicators. LEDs add magic to every electronics project. Often not understand is what else you need to make that LED work correctly. Learn what current limiting resistors do for LEDs and watch what happens when you don’t use one. The most common…
