Clem introduces the "Blooper", USB Looper, a modern null-modem style tool for UART debugging, device emulation and file transfer without a network. See how it logs serial...
What if your alarm clock launched a rocket instead of playing a gentle tone? In this project, Milos turns the LEGO NASA Artemis SLS into a motorised, Arduino-powered...
In this project, Clem builds GimmeGPIO, a compact USB-to-GPIO board that brings Raspberry Pi–style GPIO to almost any computer. Using an ESP32-S2 and a Pi-compatible...
In this episode, Clem walks through his new electronics workbench and explains why he chose each part of the setup, from the adjustable desk and fume extraction to power...
In this project, Milos builds a mobile smart cabinet for his 3D printer, filament dryer, tools, and filament storage, combining workshop organisation with safety and...
Pat takes a practical look at Bluetooth 6.0 channel sounding using Nordic’s nRF54L15 DK, breaking down how RTT, phase-based ranging, and the new sounding packets behave...
Mark takes you through the full build of a DIY pulse induction metal detector and explains the principles behind how it detects metal. He covers the electronics design...
Clem Mayer (Mayer Makes) walks through a fully homemade programming and test rig designed for small-batch electronics production. Built around a Raspberry Pi and the...
Join Milos as he tackles a familiar problem: it’s the holiday season, there’s lots of delicious food and candy everywhere, and it’s too cold to go out much. To help with...
Clem rebuilds the 3D Chameleon MK4 3D printer colour changer from the ground up, replacing the legacy electronics with a modern ATtiny3226 controller, TMC2209 drivers...
Join Milos as he puts together an open source heart rate monitor built around an ECG front end and an ESP32 C3, then takes it out for a run to see how it performs next...
