Remote access devices like IP KVMs are usually built around powerful single-board computers such as the Raspberry Pi. But ...

The ESP32 keeps finding new jobs in my house.

Since the launch of the first commercial Raspberry Pi — the then $35 Model B — single-board computers (SBCs) have drastically changed what can be considered a computer. With Raspberry Pi serving as ...

This C library reads rotation data and switch presses from rotary encoders. It supports mechanical encoders like KY-040 (HW-040), or EC11. It uses GPIO_IRQ interrupts for automatic event detection - ...

Exoskeleton suits have long carried a reputation for being bulky, heavy, and prohibitively expensive. For years, full-body systems capable of lifting loads or delivering lifelike VR sensations came ...

Abstract: Autonomous navigation in GPS-denied environments, such as tunnels, forests, and urban canyons, requires robust localization and obstacle avoidance without reliance on satellite signals. This ...

In a nutshell: Canadian hardware maker Ploopy is now accepting pre-orders for its latest input device. The Ploopy Knob is a 3D-printed, open-source rotary encoder featuring a high-precision sensor ...

Built a compact curve tracer with the Raspberry Pi Pico, ILI9341 touchscreen, and a custom power board — supports bipolar transistors (npn/pnp), diodes, JFETs, and MOSFETs. Here’s a preview of the ...

The core project design is attributed to Dale Whinham and his awesome mt32-pi project. Repo link: https://github.com/dwhinham/mt32-pi This PCB I designed is a ...
