We are superduper happy with the allsky1pi camera project. It has better resolution and colour images over the older allsky1 system (2006-2018) running a very old SBIG ST237A camera system. It also required a desktop computer with parallel port for the camera controller box. Keeping a desktop running outdoors in the winter did have its challenges (numerous versions of blankets, wood boxes, multiple hard drive failures, etc). and not a small amount of electricity to run (80-100 watts 24h/365d)

(that’s approx 2.4kwh/day or 876 kwh/year at our average power price of $0.15 came out to about $130/year! (not counting the dome heating or the camera controller power). We run on time-of-use billing which gave us low rates for 12hr/day mon-fri and 24hr/day on weekends and holidays.

The new project runs on an ittybitty raspberry pi and comes in under 10w for the computer and camera combined. And that comes in at only $13/year all else being equal.

It has now been running for 31 days without intervention as well!

Love it!
