Mapbag: Josh Billions (video)

Josh Billions demonstrates the Mapbag at Maker Faire Bay Area 2011. It is a bicycle messenger bag with a ring of vibrating motors sewn into its strap, whose positions correspond to compass points. This soft circuit project uses a Lilypad in conjunction with the gps feature in an Iphone, allowing the user to set a destination and be given constant haptic feedback through the fabric in order to stay on course and in the right direction. This acts as an exploratory wayfinding tool – a fun and useful alternative to a standard turn-by-turn map.

GPS Units Disable Themselves If They Go Faster Than 1,200 MPH

This is cool, GPS units disable themselves if they go faster than 1,200 mph and if they go above 60,000 feet… In GPS technology, the phrasing “COCOM Limits” is also used to refer to a limit placed to GPS tracking devices that should disable tracking when the device realizes itself to be moving faster than […]

You can see, in the near upper corner of that board, where the DC power jack has been desoldered and the pads hardwired to the battery pack. The system, called DemonEye, is now reportedly undergoing field testing.

Pneumatic Antenna Launcher uses Android, Free App for AR Scope

Pneumatic Antenna Launcher uses Android, Free App for AR Scope

We have covered Alan’s Biocca’s fantastic clearinghouse site antennalaunchers.com before, and Brookfield, CT, resident Andrew Stoev’s basic launcher design appears to be a slightly up-gunned version of Alan’s CSV19 pneumatic antenna launcher. It’s a beautiful build, but my favorite feature is the quick-release mount he added for his Android device. Using a free app called GeoCam, his phone, when so mounted, becomes an augmented-reality aiming scope that provides GPS location, compass orientation, and (probably most usefully for this purpose) phone inclination data.
