Hosts Elliot Williams and Al Williams review the week's top hacks, including a DIY scanning tunneling microscope built by Mech Panda that images atoms, and a deep dive into power optimization for the Raspberry Pi Zero by Manaworm. They also discuss a 32-IMU sensor array by Will Wong designed for high-precision dead reckoning, and a hardware hack by Treble that enables NVMe SSDs in a ThinkPad 13. The episode concludes with long-form articles on the history and dangers of spacewalks (EVA) and the industrial mining of lead.

Hosts Chris Gammell and Dave Jones discuss the recent Antares rocket explosion, the Hackaday Prize space trip controversy, and the passing of Tom Maglioli from Car Talk. They also cover U-beam's wireless charging technology, Dr. Greg Shaver's ultrasound chip startup, and DIY projects including a Tony Stark Halloween costume and reflow oven modifications.
The host of The Electromaker Show reviews several maker projects, including Matthias Wandel’s RP2040-based microwave current sensor and Alisdair Allan’s hack of an IKEA Vindriktning air quality monitor using a Raspberry Pi Pico W. The episode also highlights Arduino Nano projects like cardboard laser tag guns and a persistence-of-vision CD display, before covering new hardware such as the GGTag e-ink RFID device, the Raspberry Breadstick, and the Orange Pi Zero 3.
Ben Krasnow, a hardware engineer at Google Life Sciences and creator of the Applied Science YouTube channel, discusses his diverse projects ranging from scanning electron microscopes to liquid nitrogen generation. He details his time at Valve, including the development of the Lighthouse tracking system and unconventional input devices like tongue and butt controllers. Krasnow also shares insights on his cookie-making robot, the technical challenges of SEM imaging, and his approach to building educational content.
Mark Johnson, the anonymous creator of the open-source Raman Pi spectrometer, discusses building a low-cost Raman spectroscopy device using a Raspberry Pi, 3D printed parts, and off-the-shelf components. He details the technical challenges of aligning optics, selecting a linear CCD over the Raspberry Pi camera module, and managing the intense documentation and video production required for the Hackaday Prize. Johnson also shares his background in electronics surplus and his fascination with high-voltage hobbyist projects like fusors.
Dave Jones, host of the EEV blog, recounts his trip to Melbourne, where he visited Agilent's mobile calibration lab (the 'Voskow') and the Australian Synchrotron. Chris Gammell discusses the new Raspberry Pi camera module and the challenges of PCB bring-up, while both hosts critique the lack of practical context in traditional engineering education.
