Mechanical gate opener comes full circle

Mechanical gate opener comes full circle

EdenTXlocation.jpgBack in 2008, I wrote a series of posts about Alvin E. Gandy’s 1965 patent “Gandy Slide-A-Way” mechanical gate opener, which uses the weight of an approaching vehicle to automatically open and close a remote vehicle gate without electrical power. The story has apparently gotten back around to Mr. Gandy’s surviving family. His niece Annie just commented:

How-To: Make Macarons

Jessica from Childerhouse perfected the French art of making macarons and shows you how with great photos along the way. These macarons can make great holiday treats or gifts!

How-To: Quick ropecraft laptop shoulder sling

It’s probably not much good against the rain, but this handy bit of urban fieldcraft from YouTuber sumitsumit would be hard to beat for showing off your DIY-fu at the local hackerspace, coffeeshop, or school. Pretty much guaranteed to impress that attractive gentleman or lady in your engineering class. It takes about 20′ of rope, includes an adjustable shoulder-strap, and–I suspect–could probably be tied or untied in ten seconds or less with practice. I don’t want to spoil sumitsumit’s reveal, so I didn’t include a screen-cap, but you can scan forward to 4:20 to see the finished product. [via Boing Boing]

Take, for instance, this demo from MIT Media Lab’s Fluid Interfaces Group who’ve created a Chrome browser extension, called DepthJS, that uses a gesture interface to control a standard web browser using a Microsoft Kinect controller. If you view the accompanying video I’m sure you’ll agree that the effect is strikingly similar to the touch-free UI from the movie Minority Report. I’m not sure if it’s the most efficient method to interface with a browser, but I think it has to be one of the coolest

Math Monday: Giant wobbler

Math Monday: Giant wobbler

A “wobbler” consists of two intersecting circles in perpendicular planes. When you roll it along the ground, it wobbles left and right as it moves forward. I saw these 18″ diameter pine disks for sale at a lumber store and thought they would make a wonderfully large wobbler. The construction simply involves cutting a slot […]
