Mike of mikeselectricstuff shows his heavily modified old BBC Micro system in a 28-minute tour of 8-bit hardware archaeology.

Dave Jones of EEVblog investigates why a 4K BenQ monitor switches itself off, tracing it to static discharge from an office chair. He uses an oscilloscope to examine the static impulses.

Chuck Moore, inventor of Forth, presents GreenArrays' 144-core asynchronous chip at Strange Loop 2013. He explains how idle cores draw almost no power and how tight code minimizes energy use.

Andrew "bunnie" Huang examines how realistic hardware supply chain attacks are, from rogue insiders to nation states, in the wake of the Bloomberg Businessweek report. He explains how undocumented components could be hidden on boards and how hard they are to spot.

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.

The first part of Robert Baruch's series on building a 6800 CPU on an FPGA with nMigen, a Python-based hardware description language. It introduces the HDL while implementing a simpler 6800 core.

Urban Bruhin, LibrePCB's main author, introduces the open-source EDA tool at FOSDEM 2018. He explains why he started it and how its library concepts differ from KiCAD.

A Plogue developer shows the custom electronic test rigs built to measure the Sega Mega Drive/Genesis sound chip (YM2612) for the chipsynth MD emulation. It covers the years of testing and reverse engineering needed to reproduce the chip's quirks accurately.

Part two of EEVblog's visit to the NASA/CSIRO Canberra Deep Space Communication Complex, showing the control room and how operators contact Voyager 2. It includes live data and spectrum displays.

EEVblog interviews Richard Stephenson of NASA's Canberra Deep Space Communications Complex about how the 70m DSS-43 dish is used to contact Voyager 2. It covers the ground antenna and low-noise receiver side of deep space communication. This is a 2023 re-release of a 2017 video.

Dave Jones of EEVblog and Richard Stephenson tour the 70m DSS43 dish at the Canberra Deep Space Communication Complex and explain how NASA talks to Voyager 2. It covers the transmitters, receivers and tracking involved.

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 short demo of typing on the Modos Paper Monitor, an open e-ink monitor, using 4-level grayscale to show low latency.

A short video of the first TRON Smart House, built in 1989 as a demonstration of ubiquitous and ambient computing in the home. It comes from the uID Center, which promoted the TRON architecture.

A 35C3 talk presenting a proof-of-concept SPI bus hardware implant with capabilities like those alleged in the Bloomberg Supermicro story, plus countermeasures for detecting such modchips.

Peter Munch-Ellingsen explains at NimConf 2021 why he wrote his own keyboard firmware in Nim instead of using QMK or Arduino. He shows that the resulting firmware is very small.

A brief clip of a Nook Simple Touch e-ink reader running PlayStation 1 games through an emulator with a hacked fast refresh rate.

A demo of Deldo, an Emacs package that lets Emacs hooks trigger vibration events on computer-controllable sex toys. It is an absurd teledildonics project that is half performance art.

A demo of the Bad Apple music video played back at 60 FPS on an e-ink display, up from 2.4 FPS in an earlier attempt. It is part of the effort behind the open source Modos e-ink monitor.

A short project video in which Greg Raiz turns a 32-inch eInk display into a wireless digital newspaper showing daily front pages. It runs for months on battery, and the code is published on GitHub.

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.

A short demonstration of radioteletype (RTTY), a digital communication mode used in amateur radio, showing what the signal sounds like.

Dave Jones of EEVblog demonstrates that a frequency counter can detect gravity through the 2g tipover effect on quartz crystal oscillators. He shows the reading shift as the instrument's orientation changes.

Louis Rossmann argues that Apple's Independent Repair Program is a PR stunt that misleads the public and burdens independent repair shops. He discusses parts access restrictions and program limits.

Der8auer tours Hetzner's test lab and shows a custom AM5 server motherboard with the CPU socket rotated 90 degrees, built for rack airflow in their AX52 servers.

CuriousMarc inspects a newly arrived Teletype Model 19, an early military unit built around a Model 15 keyboard and printer, after an initial rough cleaning. It is the first part of a restoration series and touches on 5-bit Baudot code.

A Hitachi promotional cartoon in the style of Schoolhouse Rock explaining perpendicular magnetic recording for hard drives.

A four-minute Velocity 2011 talk in which Artur Bergman, then at Wikia, argues bluntly and with profanity that SSDs should replace spinning disks in servers.

Louis Rossmann reacts to lobbyist ads in the Massachusetts right-to-repair ballot fight that suggest repair access would enable domestic abuse and discrimination, and urges support for the campaign.

Marcin Jakubowski of Open Source Ecology presents his plan to open-source blueprints for 50 cheap, buildable farming tools, a "civilization starter kit". He argues that opening the means of production can enable self-sustaining lives.

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.
