Deer deterrent power supply notes

It won't take long to find a motor you can salvage from some random piece of discarded technology once you start looking for a cheap way to provide motion to your home made deer deterrent. DC motors are common enough and much safer to work with than their bigger AC cousins which can sometimes turn way too fast to manage.

Once you've got a good motor you'll want to match it with a good adapter that will bring down the heavy AC voltage to a smaller trickle of power. These adapters are pretty common as well, and if you look closely they usually have their output voltage printed on the back with a number afterwards. That number is the level of amperage, which varies depending on the product it powers.

The best way is to just expriment by cutting off the connector end and shaving back the insulation enough so you can plug it into your new motor. I try to find motors with gear boxes on them, which works to slow things down while at the same time increasing the torque.

I've discovered that an adapter with 300 mA or less of DC amps will be barely enough to power your contraption and might only last a few months before it burns out and sometimes takes the motor with it. Try to find one with at least 600mA or more.
