Hi,
I have an Xmas decoration I made out of plywood. Two, actually - Homer and Barney from the Simpsons in Santa suits and drinking Duff beer.
Anyway, Barney's arm is sticking out holding a mug of Duff. It needs to go up and down like he is drinking it, pivoting at the shoulder. The arm is roughly 10" wide and about 3.5' long made out of 3/8" plywood, so it is heavy (I have not put it on the scale to weigh).
I would like the arm to cycle smoothly once every 5 seconds (up and back down at 0.2Hz). So I need to rig up some sort of motor to do this, and I assume it will need to be beefy. I am very experience with PIC's and PIC programming but I know nothing about electric motors or servos.
Please help! Barney's arm needs to be helping him gulp beer by next Xmas.
