“The plant-radio was build to enhance people’s relation with their plants by being able to tap into the plant’s electrophysiological signals and output the data as sound, pulsating lights and a graph. It was produced as part of a research project called Growing CoDesign, and we want it to live on here on instructables for other people to have the same experience of communicating with plants.
In the video you can hear how the radio sounds.
Casing: The main body of the radio is made in laser cut plywood. We’ve 3D printed the turnknobs and also a mount that is inside the radio holding the LED strip in place. In our version we’ve also attatched a leather strap onto the radio to make it portable, but this is optional for you to do.
Software: The radio runs on a raspberrypi 3+, where the data comes from an EMG sensor into an Arduino sketch, which controls the LED lights and forwards the data to a Processing sketch that draws the graph, and also a OpenData patch that handles the sounds.
