Retrotechtacular: Automata

automatonWriter

For a moment, suspend your worldview and adopt Descartes’s mechanistic interpretation that living beings are essentially complex machines: a collection of inherently unrelated parts that move and collide. Automata, then, represented the pinnacle of accomplishment in a mechanistic universe, requiring considerable skill to construct. Most of their inventors, such as Pierre Jaquet-Droz, were clockmakers or watchmakers, and automata like the 240-year-old boy writer are packed with moving parts to automate motion.

Jaquet-Droz’s writer is particularly impressive considering all its moving parts—nearly six thousand of them—fit entirely within the boy’s body, and that one can “program” the text that the boy composes. It may sound like a bit of a stretch to claim that these clockwork amusements were precursors to the computer, but they influenced inventors and engineers for centuries.

You’ve likely heard of the other famous automaton: The Turk, (which was actually a hoax, housing an operator inside its base). The Turk, however, managed to inspire Charles Babbage to pursue building a mechanical device capable of performing mathematical functions: the Difference Engine.

Watch some of Jaquet-Droz’s other clockwork masterpieces in a video after the break. Magicians like Robert-Houdin were responsible for building a number of automata, so we recommend you keep the mystical atmosphere flowing by checking out another magician’s performance oddities.

Performance oddities

[Mario the Magician] wrote in to let us know that he makes Hackaday a priority every morning with his coffee. Well, so do we. He also included a link to his homepage when submitting this revelation. The juicy details that are as much of a fix as the caffeine in the coffee are missing from his posts. But the hacks are solid.

Magicians are hackers. If you could go out and buy the props, the concept are unlikely to impress anyone. [Mario] demonstrates his Nickel Box and a Jedi Mind Trick he built. The Nickel Box is a mechanical contraption that somehow transports a coin from one part of a cigar box to a tiny little enclosure on top of it. The Jedi Mind Trick uses a microcontroller and an old Star Wars soundtrack cassette tape box to put on a light and sound show while it recovers your chosen card from a shuffled deck. Great demonstrations, but no word on what’s going on inside.

[Mario's] also has a collection of… performance oddities. His talking television takes an audio input and displays a 1950’s-esque oscilloscope effect on an old TV. He’s attempting to stop his heart, or burn the house down, or both with a flyback transformer lightning box. And his drawing automaton, well, you’ll just have to see it.

We believe in electrons, not magic (even though some say there are no electrons). So we want to know how those magic props are built. Like any good magician, [Mario] probably won’t reveal his secrets. If you’ve got the goods this your chance. Write a post detailing your magical prop builds and send them our way. If it’s well done we’ll feature it here on Hackaday.
