What is it about Raspberry Pi and homebrew electronics projects that seems to attract the Star Trek fans? We couldn’t possibly say, but this awesome tricorder project from Chris "directive0" Barrett is the second we’ve seen this week, so there could be a whole universe of them out there.
The shell is 3D printed, and modelled on the flip-open TR-590 Mark VI Tricorder seen in Star Trek the Next Generation that looks a bit like a Game Boy Advance SP on growth hormones (though it looks more like the TR-580 Tricorder VII in service between 2366 and 2372 to us). Custom-printed stickers supply the necessary Star Trek aesthetic.
The newest design of the mainboard includes capacitive touchscreen compatibility, and a shift register to drive the LED lighting, plus a single transistor audio amplifier. A simple LCD display provides visual output. The custom PCB requires further revisions, so the Tricorder isn’t fully functional yet. PicorderOS, a Python library, runs the show, unifying the different modules under a custom user interface. You can read about the whole ingenious project on Barrett’s wiki.
