James Houston's entry to Radiohead's Nude remix contest, performing the 6/8, 63bpm song on obsolete hardware such as hard drives, a dot matrix printer, a scanner and a ZX Spectrum.

DIY Perks shows how to modify devices that use older USB connectors so they charge and connect over USB Type-C. He solders in a USB-C connector board and works through cases such as dongle-dependent gadgets and a mouse receiver.

A demo of Quake's E1M1 rendered as vector graphics on a Hitachi oscilloscope. A laptop generates the audio signal that the scope draws.

Strange Parts spends four months, seven custom circuit boards and several disassembled iPhones adding a working headphone jack to an iPhone 7 in China. The build is documented in detail.

Microsoft's Tony Chen explains how the Xbox One was designed to resist physical attacks, including secure boot, encrypted memory, a security processor and a hypervisor. The goal was to make any hardware attack cost more than the price of many games.

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.

Christopher Domas presents research at DEF CON 26 showing a hidden alternate instruction set and undocumented hardware backdoor in some x86 processors, found on a third-party CPU. He uses it to ask how feasible wider hardware backdoors are.

A long Gamers Nexus investigation into how volatile US tariffs affect the computer hardware industry. It interviews manufacturers and sellers about costs, margins and why moving production to the US is hard.

Bill Dally of NVIDIA gives a Hot Chips 2023 keynote on the challenges of building hardware for deep learning. He traces how GPUs have been adapted for machine learning, especially training.

A roughly 3.5-hour Gamers Nexus investigation into rising PC component prices, driven largely by AI data-center demand for memory and other hardware. It draws on interviews with industry figures to argue that personal computing and ownership are being eroded.

A two-hour Oxide and Friends session answering questions after shipping the first Oxide rack. Topics include making hardware as a startup and why Oxide chose illumos.

Louis Rossmann, a Macbook repair shop owner, goes through a long list of Apple hardware engineering failures, from GPU defects to keyboards and repair practices.

2kliksphilip examines UserBenchmark, a hardware comparison site known for strongly biased, pro-Intel writing. The video explains the site's credibility problems and points viewers to better sources for CPU and GPU information.
