Hoverboard Comes To Life

[vimeo=http://vimeo.com/11968215]

This installation by artist [Nils Goudagnin] is a recreation of the hoverboard from Back to the Future II. We would like to see inside that plinth. We’ve seen levitating magnets before, but this is particularly stable. He says he is using lasers and a control system of some kind to stabilize it. Just to guess, we’d say that the lasers determine the distance of the board and an array of electromagnets below is adjusted to keep it level. Then again, we might be over thinking this. Even though it can’t be ridden, we’d love to have one around the office just to look at.

Simplest Most Useless Machine

[Brett] posted about his most useless machine build. His project gives us a chance to massacre the language in the title because it uses the lowest parts count we’ve see with these machines. The logic is controlled by our friend, the 555 timer. Add to that just one servo motor, two switches, three resistors, two caps, a diode, and a battery pack and you’re in business. The hardest part to find locally is the servo but check at a hobby/RC store. If you don’t have to put in a parts order this can be your next impulse project.

Show Us Your Most Useless Machine

We were fortunate enough to StumbleUpon the most useless machine ever. Delightful! Eclipsed perhaps by the world’s most useless machine copy. We say that because the doll arm looks more realistic which creeps us out in a very entertaining way. So these machines aren’t useless, they provide entertainment.

We, on the other hand, have had some projects that really fell on their faces. With that in mind, show use your most useless machine. Please leave a comment after the beep.
