Emerson’s handheld scanner is built on top of a Raspberry Pi and uses various sensors to scan for RF signals and thermal bodies. It even has a built-in speaker to play the radio signals out loud.
This was Emerson’s first foray into Raspberry Pi territory and the results were absolutely worth it. The test version of the Raspberry Pi scanner was housed inside a Tupperware container which he affectionately dubbed the world’s first redneck tricorder and, according to Emerson, was able to accurately detect a Klingon trailer park.
