It's a great idea. I'll be setting mine up tomorrow (lucky me is on vacations). I might take a few pics on how it went too. Following Don's advise, I will also try it at 8 hours intervals, and 16 seconds each time.
As for the Hubba, it was a real joke. And for a moment, I thought it was broken until I read a few threads on the net. So very happy I paid almost nothing for it.
