Free Your Harley From The Dealer
Daniel Henzulea built a dealer-grade diagnostic tool for Harley-Davidson motorcycles using an ESP32. Harley bikes use a custom six-pin diagnostic port carrying a CAN bus instead of the standard OBD-II port. A CAN transceiver connects this port to an Xtensa-based ESP32, and the software exposes every function. What used to be closed source and prohibitively expensive is now open to all.

GTA.js, a reimplementation of the 1997 Grand Theft Auto engine in JavaScript and WebGL
Dự án GTA.js tái tạo lại engine của game Grand Theft Auto năm 1997 bằng JavaScript và WebGL, có thể chơi tại gtajs.wtf. Đây là bản reimplement chứ không phải emulator, nên một số vật lý và animation khác với bản gốc, nhưng engine nhiệm vụ chính xác dựa trên tài liệu mtd.doc. Tác giả sử dụng Gemini AI để triển khai hầu hết các tính năng, tham khảo tài liệu mở, ghi chú cộng đồng và trí nhớ cá nhân về game. Hiện tại game đã chơi được nhưng cảnh sát (cops) vẫn chưa được implement.
Lập trình viên nên đọc bài này để khám phá cách tái tạo lại engine game cổ bằng JavaScript và WebGL từ con số không.

Undervolting my Ryzen 7 5800X3D taught me that lower voltage doesn't have to mean lower performance
Turns out, it isn't just about lowering temperatures.

Saving A Vintage High-Voltage Power Supply From The Scrap Heap
A Fluke Model 407 high-voltage power supply gets rescued from the scrap heap and diagnosed on video. Mr Carlson powers it up safely using an isolated transformer and a current-limited variac, avoiding the risk of full power on old components. The vacuum-tube-and-circuit-board unit shows no visible damage but its output misbehaves. Using the original schematics, he traces the fault to a single faulty capacitor in the feedback loop that keeps output voltage constant.
