Ok so installing #talos from a usb stick didn’t work as it wanted to use the stick as the system disk. Had to image directly on to the internal SSD.

Still, the first worker node is up and running. Couple more to get going. All eBay HP EliteDesk Mini G2s with an i5-6500 processor and 16GB.

Will be selling some 8GB #raspberryPi 4s in a couple of weeks after the upgrade. If you are in the UK and interested let me know…

Today I successfully got #Rust code working for a #RaspberryPi #PicoW board! Not bad. All credit goes to the toolchains and projects... my efforts here are purely exploratory / discovery. My current status is I got some Pico / Pico W sample code working and then merged some samples together to form a foundation I'll build more code on top of. The merged code achieves:

  1. DHCP to local network
  2. Listen and respond to TCP
  3. Poke a GPIO (blink)
  4. Logging to USB-TTY

The real TL;DR is: The embassy project seems to be the best starting point for Rust on a Pico W. (Not a Pico 2, this is an older RP2040 board.)

The long version is: yvan.seth.id.au/rusty-pico-w.h

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.

So, aktuell habe ich 2 #pihole. Einer ist natürlich überflüssig. Aber ich wollte von einem Pi 1 auf einen Pi 3B umziehen, um dann zusätzlich noch #Docker zu installieren und darin noch irgendwas an Software laufen zu lassen, z. B. #Vaultwarden und mal schauen, was noch so geht bzw Sinn macht. #Immich (Alternative zu Google Photos) und #Nextcloud wären ganz nett, aber vor allem ersteres wäre mit Inhalt sowieso viel zu groß für die 128-GB-SD-Karte im Pi.

Für #immich und anderes würde sich eigentlich mein NAS (Diskstation) anbieten, aber leider ist das Ding zu alt und da kann ich kein Docker installieren.

Gerade kam mir noch in den Sinn, dass ich mir ja auch nen Thinclient für kleines Geld zulegen könnte. Puh, ich komm immer von Hölzchen auf Stöckchen, aber eigentlich habe ich eh viel zu wenig Zeit für solche Hobbies. Aber die Möglichkeiten wären da schon andere und theoretisch würde es sich lohnen.
