Episode 691: How Accurate...
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...
In this episode, Milos upgrades his open-source PlatypusBot into Perry the PlatypusBot, transforming a simple Arduino-based rover into a full ROS2-powered robotics platform...
Clem Mayer builds a real working communicator inspired by classic sci-fi, a handheld badge that actually makes phone calls. Powered by an ESP32-S3 and a SIM800L GSM module...
Mark combines two of his past builds, the Larson Scanner and the Vocoder, into a single 3D printed “Cylon Pumpkin” for Halloween 2025. The project features a reusable...
In this episode, Milos transforms a $10 flea-market air fryer into a fully functional smart filament dryer using the Arduino Uno R4 WiFi. By connecting it to the Arduino...
Join Natasha as she builds a custom LED matrix display from scratch, exploring the challenges of driving a large number of LEDs efficiently while keeping the design compact...
Mark builds a motion-activated “haunted painting” using an ESP32, a MAX98357 I²S audio board, and a PIR motion sensor to make a framed photo whisper or talk when someone...
Can you run Linux on an ESP 32? Yes! W hile a normal ESP 32 can’t run L inux (yet ) , one specific variant can. The ESP32-S3-N8R8 is now able to boot a L inux port for...
Clem (MakerMakes) takes inspiration from Tom Morello of Rage Against the Machine to build Dröne, a DIY body-controlled synth that recreates Morello’s famous “cable tip...
Mark builds a mint tin emergency radio using an Arduino Nano, a TEA5767 FM receiver module, a custom PCB, and a coin cell–powered microcontroller-controlled supply. The...
Andy takes a 1987 Sony Watchman portable CRT TV and transforms it into a working retro arcade system—without modifying the TV itself. Using a Raspberry Pi Pico, custom...
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...
