I built a 9' tall Ferris wheel out of PVC and is powered by wiper motor. It has been up and running the past two years using a 12V battery with a battery tender. My issue is I can't control it when my Christmas light show starts unless I physically walk up to it and turn it off, then back on 20 mins later. Running 3 to 4 shows a night for over a month is a lot of trips to the Ferris wheel!
If I can use a DC power supply I can control the AC going into it automatically.
