Dave Jones builds the Evil Mad Scientist discrete-component 555 timer kit, then tests it and explains the internal circuitry of the 555 at transistor level. He finishes with scope waveforms.

Rick Hartley gives a roughly two-hour live training on proper grounding in PCB design. He explains how energy actually flows in the space between conductors, and how that governs noise, EMI, return paths and signal reflections.

A WIRED Future Cities documentary on Shenzhen, covering its hardware-prototyping culture and shanzhai copycat manufacturing. It looks at how the city's ecosystem evolved and what the rest of the world can learn.

Rick Hartley's AltiumLive keynote on differential pairs in PC boards. He argues the rules from cables and twisted pairs do not carry over, and covers which pair geometry gives the best impedance control, the right spacing, routing practice and how much skew is acceptable.

Khalil Estell's CppCon 2024 talk argues C++ exceptions can reduce binary size in firmware. He digs into how exceptions work and how to shrink their code footprint on embedded platforms.

A roughly three-hour screen recording of designing a barebones STM32F4 board in KiCad, covering schematic, four-layer layout and routing, USB and a buck converter. It ends with ordering manufacture and assembly through JLCPCB.

A 100-minute tutorial from Phil's Lab on designing an STM32-based 'black pill' PCB in KiCad 6. It covers schematic capture, two-layer layout and routing, USB, and sending the board for manufacture and assembly.

A Ropecon 2019 talk by a lighting designer and a software engineer on how the Odysseus larp spaceship was built, using over ten IT systems, hundreds of lights and dozens of speakers. It covers the lessons learned.

Ang Cui and Jonathan Voris present firmware modification attacks on networked printers at 28c3, showing how HP printers can be compromised and used as footholds for malware inside sensitive networks.

A 105-minute technical deep dive from Noise In Space evaluating whether Starlink satellites could work as synthetic aperture radar. It covers SAR signal-to-noise, amplifiers, antennas, duplexing, phased array beamforming and simulations of V2 Mini and V3 satellites.

A Curry On talk by Lars Bak, known for V8 and Dart, on building a secure and robust IoT development platform. It discusses language and VM design choices for small devices.

An Autoline After Hours episode where Sandy Munro discusses his complete teardown of the BMW i3, along with automotive journalists. It covers the car's carbon fiber construction and manufacturing technology.

An Autoline After Hours episode with teardown expert Sandy Munro and a panel of auto journalists. It covers his Tesla Model 3 teardown, including the battery, drive modules, build quality and manufacturing automation.

Louis Rossmann argues that Apple designs and supports its products in ways that force planned obsolescence and obstruct independent repair. He draws on his experience repairing MacBooks and campaigns for right to repair.

A 37C3 talk on how a series of Polish electric trains stopped working after servicing by an independent company. The speakers explain how train control systems work and how they reverse-engineered the software lockouts.

A full-day recording of the University of Utah computer science department's 50th anniversary event with panels, keynotes and talks by alumni and pioneers. It includes Ivan Sutherland's presentation on single flux quantum electronics.

Engineer Sandy Munro joins an Autoline panel for a 100-minute deep dive on Tesla's design and manufacturing, including the Model 3 and its motors.
