[Richie Brown] created an electric mannequin leg maraca. The leg is filled with little bits of plastic, metal, and wood. Hook it up to a looping pedal, add a piezo disc mic, and you’ve got an unusual instrument with a lot of potential. [Brown] has other projects that encourage interaction and invite curiosity, from disembodied mannequin parts to repurposed piano keyboards. The creations come attached with contact mics that pick up noises as people touch, poke, and play around with them.

Io9’s Build A Lifeform Contest

There’s still time to enter io9’s Build a Lifeform contest. Synthetic biologists, get cracking on the design of that synthetic lifeform or BioBricks lifeform! The rules are pretty straightforward; you need to propose a lifeform design that would be scientifically viable. The BioBricks lifeform part of the contest requires that your design needs to not only be scientifically viable, you have to explain how you would create it in a lab, and you get extra points if you already have an organism. The deadline is August 25, 2008. You could win the opportunity to attend an all-expenses-paid trip to the Synthetic Biology Conference in Hong Kong or $1000 and a chance to get your creature drawn by a cool comic book artist.
1920s Navigation System And More

And now, for your amusement, we present to you a navigation system from the 1920s. It’s not so much a satellite navigation system as it is a tiny map mounted in a wristwatch, but for the available technology of the era, this was a pretty ingenious invention, Other (and somewhat more bizarre) entries on this list of over a dozen other inventions from the early part of the 20th century include a finger stretcher, an eyeball massager, and mustache guards. Although most of these inventions seem laughable today, they are an interesting study in finding creative solutions to real problems. After all, what these inventors did a hundred years ago with gears and paper is pretty much what we do today with transistors and LEDs.

USB Switched Power Strip

[toymotorhead] pieced together this USB controlled power strip to help with his electrical bill. His goal was to be able to have devices turned off automatically when he shut down his computer as well as powered on when he turned his computer on. Another requirement was that the USB be isolated to protect the motherboard from spikes.
The cost of the parts in total were less than $30, and consisted of a solid state relay, some fuses, and some transient voltage surge suppressing diodes. The unit only switches power off or on depending on whether or not the computer is powered up, it doesn’t control the outlets via software. He goes pretty in depth as to how everything works as well as showing nice diagrams and pictures. This should be a fairly quick and simple project, as long as you take the proper precautions for working with high voltage.
How To Hotwire Your Own Car

Picture this scenario: it’s 2 AM, you’re stuck somewhere you’d rather not be, and you’ve lost your car keys. If you can’t call the Auto Club, what do you do? Hotwire your own car, of course. Wired.com has a wiki article detailing all the things you need to do to get that car running: how to identify which wires to connect, potential pitfalls of newer cars that require an RFID chip in the key, and so on. Of course, hotwiring a car that doesn’t belong to you is illegal, but this is one of those skills-like lockpicking-which just might come in handy in an emergency.

Hack Your Customer Service Rep

Hacks come in all forms, and psychological hacks are no different. [Noah Goldstein], a behavioral scientist at the University of Chicago, has written a book in which he details scientifically proven methods of persuading others. One of these methods stands out as being particularly useful at alleviating one of the most aggravating aspects of modern life: dealing with customer service representatives over the telephone.
The trick? Be nice, compliment the rep on doing a good job, and offer to write a letter of recommendation. Since it stands to reason that the customer service rep is probably having a crappier day than you (imagine having to talk to a hundred annoyed people five days a week and you’ll get the idea), making the rep feel appreciated is likely to make them want to do more for you in return.

Wiimote Missile Launcher

[toelle] has shown yet another use for the Wiimote by having it auto aim his USB missle launcher. The bill of materials is pretty simple: a Wiimote, a motorized USB missile launcher, some duct tape and glovepie.
Simply tape the Wiimote to the missile launcher, install glove pie and follow his instructions for some custom code and off you go. He goes in depth on how to connect the Wiimote to the PC, as well as details on how the custom code works. It only tracks IR targets right now, which is a bit of a bummer, but that would see TV remotes right?
Is there any way this could be combined with the sonar controlled missle launcher that we covered in July?
