UmbrelOS – A Debian-based personal home cloud OS with a slick user interface

UmbrelOS is a Debian-based home cloud OS with a neat web-based interface that works on devices like Raspberry Pi SBCs, mini PCs, old computers, and more. Having been first released in 2020, the OS is not exactly new, but I only discovered it today after noticing it was one of the supported operating systems for the Pironman 5 Pro Max enclosure for the Raspberry Pi 5. It initially launched as a tool for running a Bitcoin full node on a Raspberry Pi easily, but eventually turned into a home cloud OS that competes against other open-source solutions such as OpenMediaVault or CasaOS/ZimaOS. UmbrelOS highlights: Intuitive web dashboard at umbrel.local or your device’s IP. Umbrel App Store — Over 300 apps, including Nextcloud or Immich for media and document storage, Jellyfin for media streaming, Home Assistant automation framework, Vaultwarden password manager, Bitcoin and Lightning nodes, AdGuard Home adblocker, and AI-related tools […]

Bee Write Back – A Raspberry Pi Zero 2 W-based DIY writerdeck with 5.5-inch OLED and mechanical keyboard

Based on Raspberry Pi Zero 2 W, the Bee Write Back writerdeck is another DIY project that should be relatively easy to reproduce, since it relies on off-the-shelf parts, including an OLED and mechanical key switches and caps, as well as a 3D printed enclosure. Simon (shmimel) had trouble falling asleep and found out that journaling helped him a lot, but he was not so fond of writing in a physical journal. So instead, he created the Bee Write Back journal/writerdeck as a distraction-free writing machine, and the result looks pretty neat. Bee Write Back key components: Raspberry Pi Zero 2 W SBC with Broadcom BCM2711 quad-core Cortex-A53 SoC, 512 MB RAM, WiFi 4 and Bluetooth 4.2 Display – 5.5-inch AMOLED screen with 1280 x 720 resolution($52 on AliExpress) Keyboard accessories 47x switches 47x keycaps YMDK Air40 keyboard PCB (about $30 on AliExpress) Power – Seengreat Pi Zero UPS USB HUB […]
