Check (or cheques) have long been a standard way for moving money from one bank account to another. They’re essentially little more than a codified document that puts the necessary information in a standard format to ease processing by all parties involved in a given transaction. The check was once a routine, if tedious, way […]
Automotive headlights started out burning acetylene, before regular electric lightbulbs made them obsolete. In due time, halogen bulbs took over, before the industry began to explore even newer technologies like HID lamps for greater brightness. Laser headlights stood as the next leap forward, promising greater visibility and better light distribution. Only, the fairytale didn’t last. […]
We often think that if a piece of software had the level of documentation you usually see for hardware, you wouldn’t think much of it. Sure, there are exceptions. Some hardware is beautifully documented, and poorly documented software is everywhere. [Graham Sutherland’s] been reviewing schematics and put together some notes on what makes a clean […]
Around the globe, some classrooms are using fancy digital handheld devices to let people answer questions. One such example of this hardware is the Smart Response PE. These devices are largely useless outside the classroom, so [Ray Burne] decided to hack one for our 2025 One Hertz Challenge. The Smart Response PE device is similar […]
The Etch-A-Sketch has been a popular toy for decades. It can be fun to draw on, but you have to get things right the first time, because there’s no undo button. [Tekavou] decided to recreate this popular toy in digital form instead to give it more capabilities. The build relies on an Inkplate e-paper screen […]
Modern competitive games have a great deal of anti-cheat software working to make sure you can’t hack the games to get a competitive advantage. [Kamal Carter] decided to work around this by building a physical aimbot for popular FPS Valorant. The concept is straightforward enough. [Kamal] decided to hardmount an optical mouse to a frame, […]
Humanity pretty much has Pi figured out at this point. We’ve calculated it many times over and are confident about what it is down to many, many decimal places. However, if you fancy estimating it with some electronic assistance, you might find this project from [Roni Bandini] interesting. [Roni] programmed an Arduino Nano R4 to […]
In his regular browsing on AliExpress, [Ben Jeffrey] came across something he didn’t understand—a $5 fiber optic to RF cable TV adapter. It was excessively cheap, and even more mysteriously, this thing didn’t even need power. He had to know how it worked, so he bought one and got down to tinkering with it. Inside […]
When building a model rocket, it can be fun to get into the maths of it all—calculating the expected performance of your build, and then seeing how it measures up in the real world. To aid in that task, [Rotislav Persion] has created a simple web-based simulator for charting the potential performance of your own […]
When your GPU fan goes rogue with an unholy screech, you either shell out for a new one or you go full hacker mode. Well, [ashafq] did the latter. The result is a delightfully nerdy fan controller powered by an ATTiny85 and governed by a DS18B20 temperature sensor. We all know a silent workstation is […]
