THP Entry: The Improved Open Source Tricorder


Since [Gene Roddenberry] traveled back in time from the 23rd century, the idea of a small, portable device has wound its way through the social consciousness, eventually turning into things like smartphones, PDAs, and all the other technological gadgetry of modern life. A few years ago, [Peter Jansen] started The Tricorder Project, the start of the ultimate expression of [Mr. Roddneberry]‘s electronic swiss army knife. Now [Peter] is building a better, smaller version for The Hackaday Prize.

[Peter]‘s first tricorders borrowed their design heavily from The Next Generation props with a fold-out section, two displays, and a bulky front packed to the gills with sensors and detectors. Accurate if you’re cosplaying, but not the most practical in terms of interface and human factors consideration. These constraints led [Peter] to completely redesign his tricorder, disregarding the painted wooden blocks found on Enterprise and putting all the electronics in a more usable form factor.

A muse of sorts was found in the Radiation Watch, a tiny, handheld Geiger counter meant as an add-on to smartphones. [Peter] envisions a small ~1.5″ OLED display on top, a capacitive sensing wheel in the middle, and a swipe bar at the bottom. Basically, it looks like a 1st gen iPod nano, but much, much more useful.

Plans for what to put in this improved tricorder include temperature, humidity, pressure, and gas sensors, a 3-axis magnetometer, x-ray and gamma ray detectors, a polarimeter, colorimeter, spectrometer, 9-axis IMU, a microphone, a lightning sensor, and WiFi courtesy of TI’s CC3000 module. Also included is something akin to a nuclear event detector; if it still exists, there has been no nuclear event.

It’s an astonishing array of technology packed into an extremely small enclosure – impressive for something that is essentially a homebrew device.Even if it doesn’t win the Hackaday Prize, it’s still an ambitious attempt at putting data collection and science in everyone’s pocket – just like in Star Trek.
