Karen sez, "Instructables user lvl_joe has built the ultimate Fire-Breathing Animatronic Pony from a FurReal Butterscotch play pony."
For Maker Faire Detroit 2011, I displayed a hack I made to a FurReal Friends Butterscotch Pony. My fellow LVL1 Hackers and I had taken control of the motor control system of the toy and added a flame thrower to it. It seemed to go over really well with the crowd, so I am putting up the information for anyone to make there own. It was a blast to make and I hope everyone has as much fun remaking it. Just remember that this project uses Fire and should only be built and operated by no less then 2 adults with appropriate experience in fire safety and proper fire safety equipment on hand.
Make a Fire Breathing Animetronic Pony from FurReal Butterscotch or S'Mores
Etsy seller Patricaia Rodriguez has created an astounding Hallowe'en prop: an animatronic door inset with an LCD that looks like a window showing a corridor beyond it. An axe-murderer stalks down the hallway, glares menacingly at you, then begins to attack the door with his axe. Each blow of the axe is synchronized with a mechanism that makes the door shake violently and causes "dents" to appear in the material, bringing the illusion to life.
You can buy the door and video together, or just the video and detailed instructions for recreating the door.
Update: from the comments, Emily Rugburn sez, "As someone who has produced fx for the haunted attraction industry, I feel compelled to tell you that this is a rip-off of another company's effect from 2 years ago - Pale Night Productions, with whom I am not affiliated."
