I'm working on a pumpkin creep and plan to make the head turn. The prop is listed on a different thread
. For this discussion I'm only focusing on the head.
This isn't a normal sized head, nor does it have a neck as you might traditionally have on a human body. So the mechanics will be a bit different. I simply want to turn a pumpkin head from side to side. Switching polarity on a gear motor is fine. Unfortunately, the little black gear motors are hard to find if at all. Whatever I do, it must fit inside a pumpkin sized head and it must be reasonably stable.
This is a quick sketch of what I'm thinking I'd do with a 12v gear motor. Imagine the branches of the cross section being longer and attached to the sides from the inside.
I'm interested in any other ideas. If you mention a specific motor, please link to it and make sure it's in stock. I have a white deer motor which I could use if I don't have a better alternative.
I considered a servo but I don't think thats going to work well to pivot the head and be sturdy enough to last for several years. There's no way a wiper motor would work well for this. Thoughts?
