A small but very beautiful project.
k3s cluster of four Raspberry Pi Zero 2 W

The parts list is very short, but unfortunately, that doesn’t mean it’s easy to get them now (October 2022):

The assembly video on TikTok:

And a couple more pictures, enjoy 🙂

P.S.

As you can see I use SD cards, which are very unreliable. The whole project is done in the first place since it looks beautiful.
I use the Raspberry Pi 4 occasionally (Home Assistant is there now), and the cluster was only made as a proof of concept.

How do I go about making something like this without a PoE hat (my router doesn’t have PoE)? The cluster hat says it doesn’t supply enough power for the Pi Zero 2 W’s, so how do I get enough power to the hat to power the Pi Zero 2 W’s?
