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)<\/p>\n<p>(that&#8217;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.<\/p>\n<p>The new project runs on an ittybitty raspberry pi  and comes in under 10w for the computer and camera combined.
