When you flip a switch, the coffin lid opens and a smiling red eyed ghost arises. The ghost flings some candy, pushes the switch back and returns to rest. Then, the coffin lid closes.

Step 1:

Major parts include:

4.5 rpm motor  #155821 Jameco.com
1.8 rpm motor  #176050 Jameco.com
Two shaft couplers  #162270 Jameco.com
Servo motor #358635 Jameco.com
Arduino microcontroller  #2121105 Jameco.com
Four limit switches  #275-0016 Radio Shack
One Toggle Switch  #275-652 Radio Shack
Three diodes  1N4004
Two Red LED's
Five White LED's

Wood, wire, screws
3 feet aluminum trim channel for 1/4" plywood (or something else stiff for the ghost spine)

If you choose to build without the "candy flinging arm," you can eliminate the microcontroller and servo motor (everything to the left and above the red line on the schematic).
AHHH HAHAHAHAH. the videos the best!
i love this cos everyone is waiting for the ghost to reach its furthest travel before throwing the sweets but it does it before , so the surprise element , and i love your whole demeanor before , quality
Is this setup like the Useless Machine? It is pretty sweet! It's creepy because it goes so slow. I feel like, at any moment, the ghost will just fly at me.
It is like a large Useless Machine--but it throws candy, so that makes it useful?
I don't think any Useless Machine is really useless. Yours definitely isn't! When anything involves candy, there is no possibility for uselessness.
