It’s interesting how “the future” sneaks up on you. One obvious source of inspiration for the products themselves, and for the people that would eventually build the data-driven world we live in today, is Star Trek. One of the most intriguing pieces of tech that these future-dwellers possessed was a device called a Tricorder, giving them all kinds of useful situational info. Though we aren’t quite to that stage in computer development — yet — that didn’t stop YouTuber obso1337 from turning a toy tricorder into something that works in a more realistic way using a Raspberry Pi Zero.
The Picorder — which “may” not tell you all the info that Enterprise crew could glean from their devices — still features several sensors, such as temperature, acceleration, and magnetic field strength. This data is shown as a series of sliders or trend lines on a small display embedded in the top portion of the gadget. An 8x8 LED matrix included on the Sense HAT for data collection is used to power a sort of secondary blinking display.
Of note is that though obso1337 is a “TNG guy, born and raised,” in order to easily fit all of the needed components, he used the larger Original Series device as a housing. For much much more detail on this build, you can check out the video below and finds its code on GitHub.
