How to Select Component Values for P-Channel MOSFET Reverse Polarity Protection
– The MOSFET approach gives you the protection of a diode, but with a much lower voltage drop. – Destroying a project by connecting the power supply the wrong way is a nightmare. Haven’t we all been there?… To add some extra protection to my own projects, I’ve made a small board and this guide…

A practical resource for professors and teachers in electronics engineering and STEM
Full documentation for the Transistor Multivibrator Experimentation Board v2 is now available. It ended up being around 30 pages and doesn’t just contain schematics. It explains how the circuits actually work, what happens during the switching cycles, and how component values affect the behaviour. It includes complete, tested circuits for: * Astable Multivibrator * Bistable…

Annual Build Your Own UFO Convention
What topics and speakers would interest you? Location: Tentatively, the Tabernas Desert (Spain)… pending extraterrestrial approval. We will definitely hold the convention at a remote campsite with no light pollution. If you have a telescope, binoculars, an SDR, thermal camera, Geiger counter, magnetometer, or any other gadget that might detect something… unusual, bring it. You…
