   I spent 6 years building a ridiculous wooden pixel display

   A maker spent six years building Kilopixel, a 1000-pixel wooden display that changes one pixel at a time using a CNC gantry system. The project combines hardware fabrication, CNC programming, web development, and live streaming to create an interactive art installation where anyone can submit pixel art through a web interface. The display uses custom wooden pixels, stepper motors, Raspberry Pi control, and streams live to YouTube with automated timelapse generation.

   Making a Wake-on-LAN server using Tailscale, UpSnap, and Raspberry Pi

   Learn how to set up a remote Wake-on-LAN server using Tailscale's VPN network, UpSnap web application, and a Raspberry Pi. The guide covers the technical limitations of Wake-on-LAN over Layer 3 networks, provides step-by-step instructions for installing Tailscale and etherwake on a Raspberry Pi, and demonstrates how to deploy UpSnap as both a standalone application and Docker container. The solution enables waking sleeping devices from anywhere without opening network ports, using Tailscale's secure mesh network and optional MagicDNS for easy browser access.

   How to install TrueNAS on a Raspberry Pi

   A detailed guide on installing TrueNAS SCALE on a Raspberry Pi 5 using community-developed UEFI firmware. The process involves updating the Pi's EEPROM, installing UEFI bootloader support, and working around hardware limitations like missing Ethernet support. While functional, current UEFI limitations prevent using PCIe switches, making single-device storage controllers the only viable option for now.

   TrueNAS on Arm is finally a thing

   ARM processors are becoming viable for NAS servers, with community developers creating unofficial TrueNAS builds for ARM architecture. While official TrueNAS support remains limited to x86, a community fork now enables TrueNAS installation on ARM devices like Raspberry Pi 5 and Ampere Altra servers. This development addresses the growing interest in energy-efficient ARM-based storage solutions, though UEFI and SystemReady support challenges persist across different ARM boards.
