Fix Everything and Get Your Own Flailing Arms Tube Man

The staple of used car dealerships that prompted Houston to ban all ‘attention getting devices’ is called an ‘air dancer’ and was invented in 1996. And now you can build your own, even if until now the space requirements kept you from doing so.

[dina Amin] shows how to make one from a bunch of discarded hair dryers and stuff everybody is likely to find in his or her workshop. While the build as such is rather basic — these things are really simple devices after all — [dina Amin]’s project video takes us through the interesting detours that turn a build into a project. It touches on the topics of painting plastics, hardware repairs, diagnosing and fixing DC motors, and how hair dryers actually work. As an added bonus we get a good-looking solution for fixing that enclosure with the worn out threads. All that in five minutes flat.

And while you might not know if you need one, [dina Amin]’s wacky waving inflatable arm flailing arm tube man is pretty much guaranteed to work. Unlike this one.

Swap-O-Matic: an automat with recycling in mind

The Swap-O-Matic is vending machine built for recycling, not consuming. Instead of feeding money into the machine, you can get an item out of the machine by swapping it for something you don’t need anymore. It’s a great concept with a great retro design, probably influenced by the age of the automat.

[Lina Fenequito] and [Rick Cassidy] built the Swap-O-Matic around the time [Lina] was getting her MFA. The build was in Wired in 2005, but the project has been updated since then and has a new home at LaunchPad in Brooklyn, NY. The first version used a separate computer next to the machine that gave out combinations to locks on the doors. It looks like the new version has been improved with an integrated touchscreen and computer-activated locks leaving [Lina] and [Rick] with a very clean build.

It’s a great idea if you have a relatively homogeneous population with similar interests, so we expect to see some of these popping up at a few hackerspaces. Check out the Swap-O-Matic promo video after the break.
