Haunted Ouija Bd.--Non-Reindeer Motor
I built this animated Ouija Board for a friend who wanted one similar to mine. The first one I built I used a reindeer motor for the movement, but I wanted to make this one using a basic gear motor. It's a bit more work doing it this way, but it's a good alternative if you don't have a reindeer motor handy.

Thanks, everybody!
Iceman--There is a large magnet at the end of the wiper arm that goes back and forth underneath the Ouija Bd. It's a 2 inch bar magnet I got at Harbor Freight. There are also two small magnets stacked on top of each other mounted UNDER the moving pointer. These I got at Lowe's--they are discs about the size of a dime, and 1/4" thick. I guess it has something to do with the changes in the magnetic field as the arm moves the pointer across the board that makes it spin.
The two magnets on the pointer need to be exactly in the middle of the bottom of the pointer, letting the pointer balance on these magnets with none of the 3 legs touching the board. I also glued a piece of one of those "magic slider" things on the bottom of the magnet that touches the board. This helps it slide easier.
It all kind of happened by accident when I built the first board.
The motor is a 5 RPM motor.
I guess I can do a tutorial sometime. Would have to be after this Halloween, though.
Thanks a lot for the compliments, everyone!
I can't take all the credit. I built my first one after seeing a vid of "BuccaneerBabes" Ouija board.
Heres a video of my first one. You can see how I later improved the spinning of the pointer:
Thanks thedwin--I'm actually almost finished with a new version of my Crawling Skeleton. I should have it posted soon. I'm also working on a tutorial for it, too.
Yea, the spinning kind of happened by accident and I just worked with it to try to make it spin even more. The wiper magent and the magnet on the bottom of the pointer have be facing each other where they "attract" (not repel) each other. You can also use the same small round magnets from Lowe's on the wiper arm. Just put two stacks of two magnets side by side (about 1/8" inch apart) on the end of the wiper arm. I just use electrical tape to hold them on.
I will say if you use a reindeer motor you will get a wider arc on the wiper arm. I lost some space underneath to make room for the 5 RPM motor and its crank.
Hallowsusieboo: That's true! Just about anything lightweight that you can put a magnet on will travel across the board.
I did it with a PVC candle I made:
Or use both at the same time:
