SparkFun RedBoard Plus Development Board
SparkFun RedBoard Plus Development Board is an Arduino-compatible board that is similar to an Arduino Uno with many extra perks. This DEV-1858 development board utilizes a handy Qwiic Connect System that means no soldering or shields are required to connect it to the rest of the...

Buck converter PCB design replaces TO-220 regulators
Linear voltage regulators are used to maintaining a steady output voltage. They are step-down converters where the input voltage is always higher than the output voltage. The output voltage can be adjusted by external resistors. 78xx series is a very popular linear voltage regulator...

Tiny Isolated Dimmer with Linearly Corrected Output
Dimmers provide a way to reduce the power of resistive elements like heaters and light features by changing the waveform of the voltage applied to them. There are different approaches to the development/implementation of dimmers and there are a lot of how-to guides and projects based on...

Low voltage power supply
Dilshan Jayakody has build a low voltage power supply that is able to provide four outputs: 1.5V, 1.8V, 2.5V and 3.3V. This power supply can be used to power low voltage mcus, CPLDs and analog ICs. He writes: In this post we introduce simple and flexible, regulated low voltage...

Dekatron as Internet speed indicator
spritesmods.com has build a interner speed indicator based on a Dekatron tube, the result is great. As most electronic engineers and hobbyists do, I have a great respect for the earlier ways of controlling electrons, before it was found out that silicon could be used to miniaturize...
