Deer deterrent direction

One thing to keep in mind when using a new style rotisserie motor is its ability to reverse direction when pressure is applied in a way that tries to stop the motor. It's a safety feature that prevents motor burn out, and comes in handy if your deer deterrent gets stuck. It will also reverse direction sometimes if you lose power for longer than a few minutes.

I figured this out back in the early days of these experiments when I would come home from a trip to town and notice one or more of the deterrents were  moving backwards. At first I thought this was a flaw and started to look for a better motor, but soon learned that a direction change is a good way of keeping things mixed up.

Another way to make sure the noise is more dynamic is to play with the crinkle in the clanging tin. Adjusting this even a little can help to create a situation where the noise is less constant with a longer interval of silence.
