Alte #raspberrypi gesucht!

Auch dieses Jahr darf ich wieder meinen Linux Treiber Workshop auf der #CLT2025 halten.

Theoretisch könnten bis zu 30 Leute meinen Workshop besuchen, aktuell habe ich aber nur für 20 die Hardware. Vielleicht könnt Ihr mir helfen meine Flotte an RPis zu vergrößern:

Habt Ihr noch alte RPis (Model 1b oder Zeros) in der Schublade, die Euch zu langsam sind und die Ihr nicht mehr nutzt?

Ich kann noch bis zu 10 RPis brauchen und würde sie Euch abkaufen. Für einen RPi Model 1b würde ich 5€, für einen Zero 7€ zahlen.

Bei Interesse einfach melden. Wir können uns auf der #CLT2025 zur Übergabe treffen.

Just playing Super Mario All Stars on an RGB matrix panel as you do.

To keep things together better, I 3D printed a bracket in two pieces, the subject of a work in progress playground note: adafruit-playground.com/u/jepl

This is using a 3rd party breakout board with 3 HUB75 connectors. I recently added the ability to drive up to 3 connectors to Adafruit Piomatter, as well as temporal dithering.

In this specific interest, I'm using 2 connectors to drive a total of 4 64x64 panels. --num-planes=6 --num-temporal-planes=2 means I'm getting effective 18 bit color, albeit with the least significant 2 bits being shown on alternate refreshes, creating a tiny amount of 44Hz color shimmer.

All these "go faster" tricks together give me about 88Hz refresh rate on the panel, despite that we're still limited to about 10MB/s of data between the PI's main CPU and the PIO peripheral that's acting as the LED controller.

Lol so the pi, that runs both my pihole and my Caddy reverse proxy, went down Saturday night (no previous incidents since April 2024). No caddy means no Jellyfin for the outside world 😵

And I'm the fucking tech support now, bc selfhosting 🫡😆

My progress so far:
- pi is booting ✅
- LAN cable is not defective ✅
- pinging the pi is working ✅
- Ssh isn't working ❌

What I'll do next: connect peripherals to find out what is going on with the pi

The Register's page on deploying a Pi-Hole 6 to cut out advertising crap is interesting stuff given the vile behaviour of browser companies over recent months - theregister.com/2025/03/08/pi_

The Pi-Hole website says you can buy a complete kit for this from The Pi Hut - thepihut.com/products/official

I'm tempted.
