The base

After careful cosideration, we decided to use Raspberry Pi as our prototyping tool. This decision was mostly influenced by the complexity of the Pi, allowing us to experiment with more complicated technologies as would be possible with smaller devices like Arduino.

Conveniently, Raspberry Pi also has a dedicated camera module, which has already all required drivers pre-installed on the Pi. This saved us a lot of time in protyping stage as we were able to literally plug the camera in, enable it and then start taking pictures.

Custom 3D-printed case

The casing components were 3D–printed at the Imperial College Advanced Hackspace. To secure the camera, a drill-press was used to make a hole in the case to fit the ball-mount. The case is made from PLA (polylatic Acid), an biodegradable thermo plastic, it is environmentally friendly and safe to use.

The algorithm

The device constantly takes pictures to analyze the colours of the environment.

Many people have recently expressed their concern about privacy around wearables. Don't be concerned though, as the device automatically deletes the pictures after processing them.
