The AllSky camera comprises of a 3d printed casing designed by myself which I have fitted with a Raspberry Pi Zero, RPi HQ camera, 180 degree fisheye lens and a dew heater.
Rigged up on my roof it captures activity such as meteorites, flares, ISS passes and can also be used to capture the suns movement accross the sky (solargraphy).
All 3D print parts are available on the downloads page, and the software I use, not written by myself, is available from https://github.com/thomasjacquin/allsky.
If I were to give any advise to those wishing to build one, it would be to use a full size Raspberry Pi 4 as opposed to the Zero. The Zero performs the task well, but has limited resources, and so a ful size Pi will operate faster and be able to run more tasks.
