Hackaday editors Mike Szczys and Elliot Williams discuss the NASA Perseverance Mars landing and the closure of Fry's Electronics before diving into a series of hardware hacks. They cover using an FTDI USB-to-serial cable to output audio via pulse density modulation, Ben Krasnow's experiment measuring human calorie consumption through bomb calorimetry of feces, and Mirage C's magnetic bearing solution for correcting ball screw wobble in 3D printers. The episode also details hacking non-dimmable LED fixtures to support dimming, building high-voltage doorknob capacitors for TEA lasers, and the safety and performance trade-offs of cheap blue diode laser cutters.

Hosts Christopher and Elecia White discuss their recent experiences judging the Hackaday Prize, highlighting finalists like the Ramen Spectrometer and Chip Whisperer, and review the rapid success of Darma Kickstarter campaign. They also cover the logistics challenges faced by Light Up and the upcoming Peep camera project, while critiquing the technical accuracy of the TV show Scorpion versus the novel The Martian.
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.
Micah Elizabeth Scott, an artist and engineer known for projects like FadeCandy and the Eclipse installation, discusses her transition from making art to creating tools for other creators, specifically the Wiggleport platform. She explains how Wiggleport aims to solve synchronization challenges for multi-channel audio and sensor data, drawing inspiration from her work on the Bela project and her own 'Eclipse' art piece. Scott also details her video content strategy, including her 'Coaster Melt' series and her Patreon model, which focuses on empowering viewers through open access and inspiration rather than exclusive content.
Elecia White and Christopher White discuss the Embedded.fm Patreon book club's study of 'Data-Driven Science and Engineering' by Steven L. Brunton and J. Nathan Kutz, focusing on linear algebra, spectral methods, and the Datasaurus dozen. Christopher White details his Dogbotic 'Do-It-Yourself Rhythm Widgets' course, where he builds an analog drum machine using CMOS logic ICs, op-amps, and piezo triggers on breadboards. The hosts also explore the 'I Saved a PNG Image To A Bird' video, discussing AudioMoth ultrasonic recorders and BirdNET-Pi for field audio analysis.
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.
