This exciting Star Trek-themed Raspberry Pi project comes to us from a maker known as Directive0 on Twitter. Replica tricorders just won't cut it—Directive0 decided to make a working one with the help of a Raspberry Pi.
The project is officially dubbed TR-109 Picorder 2. The main goal was to create a self-contained Raspberry Pi "data acquisition platform" (essentially a machine with lots of sensors) that looks just like an old school tricorder.
A Pi Zero W is used as the mainboard, which provides a limited form factor and wireless support. Directive0 created custom PCBs with KiCAD to fit inside a custom 3D printed shell. The final tricorder design uses an IR thermal camera, a humidity sensor, a non-contact thermometer, and a pressure sensor.
Data is output to an ST7735 LCD display. The unit also has a few LEDs alongside working buttons. Software-wise, it uses PicorderOS, a custom Python library that links the visual interface to specific sensor modules used in the project.
