Clem shows how to reverse engineer a cheap breathalyser key-fob and re-purpose it into an Arduino-compatible sensor module. By dissecting the circuit, discovering the...
Mark takes on the challenge of building a fully functional FM superheterodyne radio without transistors or SDR, relying instead on vacuum tubes and a custom PCB design...
Miloš builds a custom Duolingo-inspired owl that sits on his monitor and reminds him to complete his Spanish lessons. Using an ESP32-C6, dual LCD displays for expressive...
Clem (aka mayermakes) builds a fully open-source, battery-powered desktop calculator from scratch, powered by an ATtiny3226 micro-controller for efficient 3V operation...
Join Mark as he builds a digital vocoder using a Teensy 4.0 and audio shield, demonstrating how audio spectrum data can be analysed and used to reconstruct sound in real...
Join us as we explore the harsh lessons learned from building a swarm of tiny robots powered by ATtiny416 microcontrollers, vibration motors, and 3V coin cells. What...
Mark builds a DEFCON-style status display using an ESP32 and addressable LEDs. Originally intended to track global alert levels, the project was reimagined as a personal...
Milos builds an open-source cardiograph signal measuring device using a Raspberry Pi Pico W. The project explores how blood pressure monitors work—both manual and automatic...
Clem builds a fully programmable lighting controller for scale models using an ESP32-S2 micro-controller. Designed to fit seamlessly into a Warhammer 40K Rhino tank,...
Milos scavenges parts from a broken robot vacuum to build a custom Wi-Fi controlled robot platform. By repurposing motors, encoders, and a swivel wheel, he creates the...
