Meshtastic Linux Native Client based on Raspberry Pi Zero 2

THIS ARTICLE IS STILL WORK IN PROGRESS

My DIY Meshtastic Home Node based on a Raspberry Pi Zero 2, the Waveshare PoE Ethernet/USB HUB HAT, and the MeshAdv Mini Launch Edition: LoRa/GPS Hat. The node is operated in the attic, powered via POE, and an Mikrotik 868 Omni antenna is on the roof.

The goal was to have a reliable node that could be easily updated and configured via SSH. POE is ideal as a power source for this purpose, as it also provides a stable network connection for MQTT connections. The switch that provides POE is buffered via a UPS.

Antenna mount

Since I live in a rented apartment,house, I decided on a non-destructive way to install the antenna on the roof. There is a metal-framed skylight in the attic, so it was obvious to use magnets. I designed two 3D-printed parts in TinkerCAD to connect the antenna and the magnets.

The first prototype wasn't a perfect fit, but it proved that the type of fastening was suitable. The second print produced perfect plastic parts, which were then assembled. The magnets hold almost too well! :)

The final product...	... on the roof.

The printed parts are made of PETG. I significantly increased the infill at the connection points compared to the rest. Once everything was in position, I also glued the two parts together.

I bought these magnets on Amazon. Apparently, people use them to fish for metal parts in ponds and rivers. Anyway, it was important to me that the magnets had a hole and were strong. These magnets fulfill both requirements.
