Hackaday editors Mike Szczys and Elliot Williams review several hardware hacks, including an acoustic camera by John Duffy, Ryan O, and Sarah Park that uses an FPGA for real-time sound localization, and a flightless pneumatic drone by Jose Manuel Hermano Barrero (Pateo) featuring 6 hand-machined aluminum engines. They also discuss a TEA laser build by Les that utilizes hex standoffs for precise alignment, a wind turbine by Fab with pitch adjustment, and a Spectra coexistence attack on Broadcom BCM4339 chips by Yiska Klassen and Francesco Gringoli. The episode concludes with a discussion on overhead wire-powered trucks and the virtual Hackaday Prize.

Hosts Chris Gammell and Dave Jones discuss a DIY drone crash video, the ADE 651 bomb detection scam, and rumors of Texas Instruments selling its OMAP processor line. They also cover Tektronix's new oscilloscope launch, a Kickstarter scam involving the Tech Sync Power System, and the future of personal robots like the Willow Garage PR2.
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.
Hosts Chris Gammell and Dave Jones field calls from listeners Stu, Vikas, and Ryan, discussing hobbyist electronics projects and budget test equipment. Vikas seeks advice on building an arbitrary waveform generator using a Raspberry Pi and a TI TLC5602 DAC, prompting a deep dive into DAC architecture, DMA, and analog filtering. Ryan, a high school student, asks for budget scope recommendations, leading to comparisons between the Analog Discovery and Rigol DS-1054Z. The hosts then analyze industry news, including the Microchip-Atmel acquisition, the Cast.AR Kickstarter delay, and Valve's automated Steam Controller manufacturing in Illinois.
The host reviews Red Pitaya's STEMlab 125-14 and MIKROE Click Add On Shield, describing the FPGA-based board as a versatile 'Swiss Army Knife' for engineers that can function as an oscilloscope, logic analyzer, or software-defined radio. Guy Dupont’s Autotuned Kazoo project is highlighted, featuring an ESP32-S3 and MEMS microphone to create a wireless MIDI controller and synthesizer using a sawtooth wave trick. Robin Mitchell’s Electromaker Educator segment demonstrates a voice-controlled Lego Planetarium upgrade using an Arduino Nano 33 IoT and stepper motors, while Wiznet’s announcement of the W55RP20 chip combining an Ethernet controller with an RP2040 is also noted.
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.
