Advanced .NET·29wBuild a Raspberry Pi kiosk with Avalonia UI and DotNetBrowser!
A guide demonstrates how to build a kiosk application on Raspberry Pi using Avalonia UI framework and DotNetBrowser. The approach runs outside the desktop environment, offering developers more flexibility than traditional lockdown browsers while combining native app capabilities with web development simplicity.
80 LEVEL·27wDeveloper Runs Minecraft On Smart Lightbulb
A developer successfully ran a Minecraft server on a smart lightbulb's BL602 microcontroller by creating Ucraft, an extremely compact server implementation. The binary is only 46-90 KB depending on authentication, with heap usage reaching 20-70 KB for up to 10 players. The project demonstrates creative resource optimization for embedded systems and is available on GitHub with build instructions.
Hacker News·29wzserge/grayskull: A tiny, dependency-free computer vision library in C for embedded systems, drones, and robotics.
Grayskull is a minimalist computer vision library for microcontrollers and resource-constrained devices. Written in pure C99 as a single header file under 1000 lines, it requires no dependencies or dynamic memory allocation. The library provides grayscale image operations including filtering (blur, Sobel edges), thresholding (Otsu, adaptive), morphology (erosion, dilation), connected components, perspective warping, FAST/ORB feature detection for object tracking, and LBP cascades for face/vehicle detection. It includes PGM file I/O and uses integer-based operations optimized for embedded systems.
All Things Open·29w12 everyday technologies powered by Linux
Linux powers a vast array of everyday technologies beyond servers and desktops. It runs NASA's space systems, Android smartphones holding 75% of the global market, smart TVs and streaming devices, modern car infotainment systems, home routers, and even Microsoft Azure infrastructure. From the International Space Station to retail checkout systems, Linux provides the stability, security, and flexibility that makes modern connected life possible. Its open source foundation enables customization across devices ranging from Kindle eReaders and smartwatches to gaming platforms like Steam Deck.
