An engineering student at the University of Arizona has built a functioning Star Trek Tricorder.
Peter Jansen, a postdoc in a lab for “Engineering Non-Traditional Sensors” at the University of Arizona, has developed (from scratch) a perfectly functional Star Trek-style Tricorder. It’s packed with sensors, displays and touchpads, and it even folds up. Plus, this is just version one: version two is much more slick.
The Tricorder Mark 1 is, for all practical purposes, nearly identical to the device that we see in Star Trek, with the possible exception of being unable to reliably distinguish a Klingon from a Romulan. It’s a self-contained, portable sensor system that can measure ambient temperature, humidity, air pressure, magnetic fields, surface temperatures, colors, ambient light level, ambient polarization, acceleration, direction, distance (ultrasonically), and of course it has a GPS receiver.
Apparently, the device is also quite adept at detecting the persistent virginity of anyone who owns a functioning Star Trek Tricorder.
