Thread: Crawling Skeleton (New Version)

I believe these are the same motors from Surplus Center at $2.99

Thought I would toss that out there for a little cost savings for everyone

No, I haven't tried that. It would be easy to find out. I could just snip the power wires, swap them and see what happens.
I'll have to try it and see. I'll post a video when I do. Have to dig him out of storage first.

Looks like another coool prop to build. Peekaboo was the most liked this year. They will go nuts with this new prop. Thanks Dave for the ez of building them.

This is a great prop.

You could use a guide line. In the body mount a double throw toggle switch. Once the prop reached the end of the tether the switch could be moved to the opposite side and reverse the polarity. Once it gets back to the end of the tether in reverse the switch toggles back to the normal polarity.

Thanks! I hope it's easy for anyone who tries to make one.

Thanks! That's a good idea. Somewhere I have a schematic I drew on wiring a DPDT switch to reverse polarity. Or just figure a way to make it battery powered, then it wouldn't need to reverse. LOL
I'm gonna try to find time this weekend and see how well it crawls backwards.

Oh man, Thats creepy ! Well done, You did yourself proud !

Thanks, MMMark!

Actually if you can power with a battery the tether idea will still be useful. The tether could be anchored in the middle of the path you want the prop to remain in. The tether is attached to your toggle switch. The prop will move until the tether pulls the switch and then work it's way backwards until the tether pulls the togle switch back to forward position.

It seems to crawl backwards as well as it does forward. I tried it this weekend.
One problem is that since the motor crank rotates so close to the ground, it's easy for the power wire to get wrapped around the motor shaft as it progresses backwards. Unless there's a way to suspend the power cord above the skeleton.
The tether idea would have the same problem, spinman. Also the fact it doesn't move in a PERFECTLY straight line. I might not trip the switch properly.

Fantastic Job Dave! Wish I had the front lawn to try something similar.
But I can definitely make use of those motors, thanks for sharing the link.
