It might not seem like a huge thing, but it's time to fix the power distribution for my Raspberry Pi 4B servers. This should do a perfect job of distributing the 24V going to each one pretty well, and 1A fuses should work out perfectly for keeping the amount of fire to a minimum. #homelab #raspberryPi

A power distribution terminal block. The left side has two positive and two negative inputs labelled DC INPUT which are screw terminals. On the bottom are some plugin screw terminals. There are 8 sets of dual terminal plugs labelled + and -. Above each dual terminal plug is an ATC-style automotive fuse. On the edges of the block are two places to mount the block to a board.

Half the #homelab is down for essential maintenance (new rack part one) and hopefully the only person that will notice is me. Incredible really…

The Reg (thanks @…) has a nice writeup of the latest incarnation of RISC OS. If you have a spare Raspberry Pi lying around (who am I kidding. Everyone has a spare Pi lying around!) it’s well worth having a play with this if you’re bored. I guarantee it’ll be unlike any other OS you’ve ever used.

What in the actual heck is going on with chrooting into a mounted :raspberrypi: #RaspberryPiOS SD card rootfs on :nixos: #NixOS?
SOLVED: One also needs to bind-mount /nix in the target system:
> sudo mkdir /mnt/nix; sudo mount -o bind /nix /mnt/nix

tmux screenshot with multiple panes, showing that /mnt has a fs mounted and the virtual trees bind-mounted, that chrooting into it doesn't work with weird 'no such file or directory' errors, showing a NixOS config with emulatedSystems set to raspberry pi compatible arm, and other stuff

Finally have the last three Raspberry Pi's installed and running. The primary and secondary servers took no time to get back online, and I basically just turned off the old VPN server and rebuilt it as it's a fairly simple process. Also, since the Pi's are using NVMe drives it makes things more than a bit snappy. #homelab

The three Raspberry Pis installed on the right-hand side of a piece of acrylic. Each is labelled (DNS1, DNS2, and TAILSCALE), all are connected to the breakout power board, each has a power hat and an NVMe hat, and all have cooling fans spinning without issue. All of the Pis are powered via a 24V DC PSU by MeanWell.

Upgraded the power to the Raspberry Pi servers...nowhere near as sketchy as before. Much easier to manage power, and very easy to add another Pi. #homelab #raspberryPi

Two Raspberry Pis connected to a 8-port terminal strip which 8x 1 amp fuses (one for each). A 24V Meanwell power supply provides power to the terminal strip.

I have programmed a small #rstats script combining the web-based #API of our SolarEdge #photovoltaic system with the local API of our go-e #wallbox.
If the car charges, the script looks up the production of the PV system and increases/decreases the charging current for the car accordingly. This makes the most of the collected #solar power. What now runs on an old #Raspberry Pi would’ve easily cost us 500 EUR installation costs – and I have full control over everything! 🤓🤩
