Inspired by the 'Useless Box' this project uses an Arduino Uno to control 2 small servo, the code picks a random servo/arm (tentacle), and moves it by a random step-size, to a randomly selected angle. pRNG is seeded in setup() with some noise from an unused pin, so we get a different play sequence each time this monstrosity is switched on.

Tentacles are from eBay (search: "finger tentacles"), they have been given a coat of the metallic paint leftover from my Steampunk'd goggles 'ible; Bowler[1] hat also from eBay.

Project features 3D printed servo arms and frame to hold servos into hat. Files for those to come.

There should be a video of it in action here:

proving that some Things are better left in my head.

Music is, of course, by Abney Park.

<p>very cool idea! </p>
<p>Thank you for your kind words!</p>
<p>For those that are living in the US. The tentacles are also available in certain Paper Source stores. Usually close to the windows with the random nick nacks and fun things.</p><p>Great looking hat. I really like it.</p>
Thank you!
