A little fire breathing pony to call your own

[Lvl_joe] has been having a little fun with fire and an animatronic pony. The skeletal horse seen above is a child’s toy denuded of its original plush shell. That’s a good thing, because those synthetic fibers don’t play very nicely with flames. The toy originally retailed for around $300 bucks, but if you’re lucky, like [Joe], you can get one second-hand for $25 or less.

Since the horse is already motorized, it’s not too hard to patch into the drivers. Here an Arduino is used to take input from a Wii Nunchuck, letting you swing the fire sprayer to and fro. A grill igniter makes sure it’s not just spraying automotive starter fluid everywhere. You can hear the click of that tiny spark repeatedly firing in the demo video after the break. The starter fluid comes in an aerosol can. A custom trigger system holds the can in a PVC pipe, and actuates the valve with a Bowden cable.

  1. FINALLY I CAN MAKE A LIFE SIZED PINKIE PIE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  2. I like the guy in the kilt in the background of the video who appears to be talking on a cell phone — I presume he’s telling somebody: “You’ll never believe what I’m looking at!”

  3. I was a little light on the information that I think readers of hack a day would be looking for. This instructable outlines what is needed to remake the pony the way I did it but truly it can do a lot more. I hope to have a more “this is what I know, use it to make something more awesome” post on the inner working of Butterscotch at lvl1.org soon.
