Ian from Electromaker reviews a variety of maker projects, including Valima’s 3D-printed 'Minority Report' kitchen timer and a miniature billiards game by Electro-Japanese. He highlights TinyML applications, such as running heart arrhythmia detection on an Arduino Mega using the Newton platform, and discusses Framework’s initiative to provide old laptop mainboards to developers to foster reuse and reduce e-waste. The episode also covers new event-based vision sensors from Metavision and crowdfunding campaigns for SMD component counters and USB-to-TTL adapters.

Hosts Elecia White and Christopher White discuss the technical implications of the 2038 time bug, the utility of the 'single-file libraries' GitHub repository for embedded development, and Christopher's hands-on MIDI project using an STM32 NUCLEO-144 board. Elecia also shares her exploration of Tiny ML for PID controller tuning and her attempt to apply for a NASA NIAC grant using curved crease origami for sensor systems.
Editors Elliot Williams and Kristina Panos review a week of hacks, including Will Gallia’s massive 7-segment display art installation, Abraham Haskins’ floppy drive PC with custom cartridges, and Sound Workshop’s flexure-based expressive synthesizer. They also discuss Eli’s ESP32 and Raspberry Pi Pico W hack to restore high scores to an 80s pinball machine, and a Cornell study on repurposing old smartphones for low-carbon computing.
Hackaday editors Mike Szczys and Elliot Williams review a week of hardware hacks, including Max Kay's ultra-low power ESP32 handheld computer and a project running support vector machine classification on an ATtiny85. They discuss Nathan's massive basement UPS built from 96 scavenged lead-acid batteries and Maurice McKay's Z-wave retrofit of a Mocha Master coffee maker. The episode also covers 3D-printed press brake tools, the history of natural nuclear reactors, and the ubiquity of barcodes.
Chris Gammell and Dave Jones discuss the Hackaday community's campaign to buy the website and form a non-profit, contrasting fixed vs. flexible funding on Indiegogo. They critique a pseudoscientific 'thought phone' called the TARC and debate the economic impact of non-profit Arduino clones on the open-source hardware ecosystem. The hosts also review new Microchip microcontrollers, the LT3081 voltage regulator, and online CAD tools like Upverter.
Hackaday editors Mike Szczys and Elliot Williams review the 2019 Hackaday Prize finalists, highlighting projects like the Axiom 100kW motor controller and the Power One breadboard power supply. They discuss Ben Krasnow’s cryogenic drill bit treatment, non-planar 3D printing techniques, and an ESP8266-based water meter reader. The episode also covers Padauk microcontrollers, massive LED cubes, radiation monitoring projects, and a deep dive into the Ada programming language.
