I'm doing it. I'm posting this picture again. You'll see a lot of nerds posting this lately, because holy fuck
This image is so fucking cool!
At the 1 o'clock and 7 o'clock positions around the edges of the planet's upper atmosphere, you can see greenish hints of aurorae. I really like how pronounced the atmosphere itself is in this photo.
At the 4 o'clock position, you can see a sunburst jutting out from behind Earth, and that's because in this picture, Earth is eclipsing the Sun.
Yes, you heard me right. The Earth is eclipsing the Sun in this picture. That means that the light you're seeing on Earth in this image is being reflected off of the Moon!
The low-light situation causes a lot of noise in some parts of the photo, which blends in nicely with the starry background. 😎
I ported MeshTNC (along with a significant portion of Meshcore's HAL) to Linux and Windows! 👀
Work in progress still. I haven't pushed the code yet. The radio wrapper is just some stubs right now, but I'm planning on adding SPI radio support soon.
A MeshCore community member is working on this Python implementation of MeshCore for Linux. It works by controlling a directly connected SPI radio (sx12xx chip)
There's a core parsing library: https://github.com/rightup/pyMC_core/
And a repeater implementation, with an extremely slick UI: https://github.com/rightup/pyMC_Repeater
It will soon support using MeshTNC radios connected over USB via KISS mode!
kissattach and the Linux kernal AX25 implementation. IP working over AX25:APRS also Just Works™️

this demonstration was at very close range (~10m) using close to the fastest LoRA preset possible using this hardware: Bandwidth 500KHz, Spreading Factor 5, Coding Rate 5 (4 is less redundant, therefore faster)
