Kontraptioneering presents No No No Bear!
What do you do with an old and thoroughly broken Teddy Ruxpin from eBay?
Turn him in to an internet meme, courtesy of a different internet meme, some servos, and a re-purposed Quadcopter flight computer!!
Our friend Will, who’s in charge of FreakFurz, had an art
opening closing recently, featuring this bear, although he was tasked with telling filthy NSFW tales of perverted ursine debauchery rather than imitating some poor, frightened kitty.
The flight computer used for Teddy’s brain was chosen because it’s built to interface with servos - lots of them, and it’s based on the ATMega328P, which means you can run Arduino code on it. Teddy’s SD card was then loaded with audio, which fed through an amplifier (based on the LM386 chip), then split between a rectified low pass filter (and on to an analog input in the flight controller) and also to the speaker.
This was early on in the firmware development. Later software gave teddy the ability to wiggle his nose, blink his eyes, get bored, and finally fall asleep. These are the fun projects.
