Re: Go Pro ???
While I haven't tried one, there are several vendors on eBay who're selling the inexpensive kitchen-timer based mechanical rotators. And Ikea was selling an even-cheaper one!
The one I've seen most-often takes a full 60 minutes to rotate 360-degrees, but folks are stacking two (or more) of them, to get there in 30-minutes, or 15-minutes.
Lots of amazing stuff coming from GoPros, these days!
