How One Line of TF2 Code Ruined This Simple Feature

https://invidious.privacyredirect.com/watch?v=-G9lwzYqsg4

Ever encountered a minor annoying bug in a video game? How about one dating back to 2018? Usually, you have no hope of fixing it, but this time is different. [Joey Cheerio] shows the first-time programmer approach to (with great difficulty) fixing a bouncy ball prop turning invisible when shot in Team Fortress 2.

It starts with a band-aid solution that hides the problem: just turn off jiggle physics! While that works, it also affects many other models in the game, and doesn’t tackle the root cause. Time to investigate. Because this ball often goes overlooked, [Joey Cheerio] didn’t even realize...

The electromechanical angle computer inside the B-52 bomber's star tracker

Before GPS, how did aircraft navigate? One important technique was celestial navigation: navigating from the positions of the stars, planets, or the sun. While celestial navigation is accurate, cannot be jammed, and doesn't require any broadcast infrastructure, it is a difficult and time-consuming process to perform manually. In the early 1960s, an automated system was developed for the B-52 bomber to automatically track stars and compute navigation information. Digital computers weren't suitable at the time, so the star tracking system performed trigonometric calculations with an electromechanical analog computer called the Angle Computer.1

Pironman 5 Pro Max Review – A Raspberry Pi 5 Tower PC case with integrated video and audio capabilities, optional UPS kit

SunFounder has sent us a sample of the Pironman 5 Pro Max tower PC case for Raspberry Pi 5 for review alongside a PiPower 5 UPS board. The “Pro Max” builds upon the Pironman 5 Max we reviewed last year, but adds a 4.3-inch capacitive touchscreen display, a 5MP camera module, two speakers, a USB microphone, and a 3.5mm audio jack. The PiPower 5 is a UPS HAT designed for Raspberry Pi Zero/Model B single board computers, and not directly compatible with the Pironman cases, but we’ll still try to use it. I’ll start this review with an unboxing of...

Boardcon Tiny1126B is a smaller and lighter Rockchip RV1126B system-on-module, yet with more I/Os

Boardcon Tiny1126B shrinks the company’s MINI1126B-P Rockchip RV1126B system-on-module (SoM) from 38x30mm to 34x30mm, targeting even more compact AI vision systems such as smart cameras, smart door locks, inspection cameras, cleaning/logistics robots, DMS (Driver Monitoring Systems), BSD (Blind Spot Detection) solutions, and smart displays. Despite its smaller size, the Tiny1126B features two 0.4mm pitch 100-pin connectors, instead of two 0.5mm pitch 80-pin connectors for its predecessors, offering even more I/Os. It’s notably gaining a USB 3.0 DRD (Dual-Role Device) interface, an extra SDMMC interface, one additional SPI and I2C interfaces, Fast Ethernet, and more. The rest of the specifications, including...

WiQwiic-32 – A compact USB-C IoT board with eight Qwiic connectors (Crowdfunding)

Hack The Board’s WiQwiic-32 is a small USB-C IoT development board based on an ESP32-S3-WROOM-1 Wi-Fi and Bluetooth module, and equipped with a 1.14-inch LCD and eight Qwiic ports for easy prototyping with compatible modules. It also features a microphone and a buzzer for audio interaction, four buttons, two RGB LEDs, and a power LED.  There aren’t any through-holes for GPIO pins, so expansion is only possible through the Qwiic connectors, although you can always add a Qwiic to header converter module if you ever need breadboard-compatible GPIO headers. WiQwiic-32 specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3...

Лабораторный откачной пост своими руками. Часть 1. Каркас, нагревательная печь

Речь об установке для вакуумной обработки самодельных ламп в любительской лаборатории-мастерской. Выделение впитанных в материалы электровакуумных приборов (стекло, металлы, слюда) газов при нагреве и понижении давления в колбе прибора [1], заставляет принимать меры для их обезгаживания, среди прочих мероприятий, это и внешний нагрев электровакуумного прибора (ЭВП) во время откачки. Здесь — отчёт о сборке каркаса откачного поста и такой нагревательной технологической электропечи — лёгкой, мобильной, точной, удобной, экономной. Из простых доступных материалов и компонентов, своими руками. Печи, пригодной и для снятия внутренних напряжений в стекле (отжига) [2] после изготовления деталей на горелке [3], печи, годящейся для горячей формовки стекла (моллирования), изготовления стеклянных витражей в...

П-171Д. Оживляем телефонный аппарат спецсвязи СССР

Приветствую всех!

С первого взгляда может показаться, что это самый обычный дисковый телефон, какие некогда стояли практически в каждом доме или офисе. Несмотря на это, внутри он устроен совершенно иначе.

Итак, в сегодняшней статье посмотрим на один из самых крутых дисковых телефонов советской эпохи. Заодно разберёмся, что у него внутри, чем он так примечателен и как подключить его к обычной телефонной сети. Как водится, будет много интересного.
