Maker Billy O’Sullivan with Shed Tech; is kicking portable Raspberry Pi projects up a notch with his wearable i2c sensor platform. This on-the-go Pi system was made from scratch by O’Sullivan; and is affectionately dubbed the Armatron; (which is unrelated to the robotic arm of the same name once sold by RadioShack).
Instead of monitoring game stats or adjusting menu options; this wearable platform provides i2c access for developing projects in real life; with the added benefit of a full-blown Linux OS. Users can plug in a number of sensors and monitor data using its OLED display.
The housing is 3D-printed and designed specifically for the Raspberry Pi Zero 2 using Fusion 360. There are three available i2c ports that can be used to attach sensors. In the video, O’Sullivan demonstrates support for a GPS module, environment sensor and more. Users can also remove the Armatron from the wrist band easily as it attaches magnetically, snapping into place as needed.
O’Sullivan made the project open source; and shares his progress over at GitHub for anyone interested in perusing the source code. It’s based on Raspberry Pi OS, adding a few tools that will interact with the platform and its various modules. Expanding its support for additional sensors requires familiarity with Python but is also possible.
