Hackaday editors Mike Szczys and Elliot Williams discuss the Open Source Hardware Association's recommendation to replace 'Master/Slave' terminology in SPI protocols with 'Controller/Peripheral' (COPI/CPOI). They then review several engineering hacks, including a variable-shape telescope mirror, a helicopter without a swashplate, and a vibratory wind generator. The episode concludes with a deep dive into repairing a MacBook GPU via micro-soldering, a heterodyne bat detector, and the discontinuation of the Segway.

Hosts Dave Jones and Chris Gamble discuss the open-source RC controller from Gizmo For You, highlighting its complex injection-molded cases and 8-layer PCB. They review Ken Lumbard's 'Reading Jim Williams' project, which curates and analyzes the application notes of legendary analog engineer Jim Williams. The hosts also cover rumors of a DARPA humanoid robot grand challenge and share experiences using CircuitLab for SPICE simulation.
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.
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 Dave Jones and Chris Gammell discuss a wide range of hardware topics, starting with Chris's preparation for Embedded World using FreeCAD and KeyCAD. They delve into Bluetooth Low Energy history and standards, then analyze the industry shift toward plug-in hybrids, citing Toyota's strategy. The conversation covers new silicon from Espressif, the TinyTapeOut project by Bitlooney, and Pete Bevilacqua's PowerMole Kickstarter, before concluding with a look at BeagleBoard.org's new Raspberry Pi-compatible board and a discussion on popular hobbyist components.
Matt Berggren, Senior Director of Product at Supply Frame and former Director of Product at Altium, discusses his vision for transforming electronics design through high-level abstraction and modular components. He details his Spartan 6 FPGA shield project, which allows Arduino-based cloud configuration of hardware, and explains the Wishbone bus standard as an open-source alternative to ARM's AHB/APB. Berggren also shares insights from his experience running grassroots electronics workshops, emphasizing the importance of substantive content over marketing to build trust in the maker community.
