Hello you :)

In December 2024, I modded a Minitel Telic 1 into an HDMI display and USB keyboard. Keyboard The Minitel keyboard is defined by an 8×8 matrix (sadly, it’s a diode-less matrix, meaning ghosting and masking may occur). Using the following matrix: ↑ Correction Annulation ↓ Shift ← → ↲ T E R Y ; - : ? G D F H * 7 4 1 .

I forgot to add to the rack feet 3D models to the 24/01/2026 article. So here they are: Download: STL Source: FreeCad

With my new addiction, I made the the mistake ??? to install Home Assistant, and wanted a thermometer and didn’t have any temperature sensor. But I remembered that the RP2040-Zeros in my drawer and the fact that they had internal temperature sensor. After a short internet search I found learnembeddedsystems’ blog especially the article titled “RP2040’s On-Board Temperature Sensor”. Code Pico-SDK Installation After opening the Pico-SDK Quick-Start Guide, I realised that their just was a AUR package, so after running yay -S pico-sdk and setting up the build environment i was done. ...

Edit: I’ve added the feet files here I have a new addiction Homelabing, and it caused me to build a Custom Rack, inspired by Symbiiote’s DIY Rack Build I’m not going to explain how to screw bolts into holes but i’m going to give you a list of all the Required Parts (3D Prints and Hardware). Required Parts 3D Prints I’ve printed almost all of the Rack 3D Printed pieces are made out of PETG. ...
