Raspberry Pis are Great. Raspberry Pis Rule!
Not only do they reduce our electrical/environmental loads, but they are stable as heck.
Our weatherpi now has an uptime of 61 days. It data logs from the acurite weather station here.
Our allskypi now has an uptime of 100 days. It data logs from our allsky camera.
Our newly configured supersidpi has an uptime of 8 days. It data logs from our SuperSID radio telescope system.
Once configured and up and running these things are great. No windows7 or windows10 system can match them.
