Mounted on a cart, next to my street piano, sits an organ grinder
monkey doll with one hand on the crank.  When children drop a penny
in his cup, held in his other hand, he cranks out a tune for them.
I'm in the background controlling the piano motor with a wireless
remote switch.  It beats feeding and caring for a live monkey, and
my little guy does all the work!

I have to plug the unit into a 110-volt power source somewhere,
though I tried to make it self-contained by placing a fully-charged
truck battery on the shelf below, connected to an 800-watt inverter
and plugging the piano into that.  The motor could hardly operate
the piano at all.  Anyone have any ideas on this?

Thank you,

 [ 800 watts power is more than one horsepower (768 watts), whereas

 [ 1/8 horsepower.  Something is wrong!  An electric skateboard motor
