This circuit is not new but is rarely used or talked about. So here is a linear VR using BJTs only

Built with Arduino UNO R4 Wi-Fi + RTC + IR Sensors + Buzzer - because Mom said "Put that book back where it belongs!")

ATmega2560 based SBC with VGA, PS/2 and SD cards - meant to run FORTH now and serve as graphic card later.

Simple Audio Spectrum Analyzer with multiple adjustable display, speed, and sensitivity modes for a customizable audio visualization experi

The 8-key macro pad with LCD isn’t just another macro pad— it's a visual, scriptable, dynamic control deck you build and own.

Smart RFID Lock using Arduino UNO R4 - keyless, portable, and automatic servo lock any space. Secure simple and smart!

custom(izable) circuit for sending some megabytes over differential pairs.

By implementing a custom micro-coded CPU that executes it directly (up to 100MHz)

It is a board that lets the Einstein computer emulate the Spectrum. Design by Tony Brewer.

My idea is to build a small solar panel using 24 power transistors in a TO3 package.

* No magic here. But I show that LEDs light up from tiny currents induced by electric fields around us, with no further electronics needed.
