“Pour Reception”: An Arduino-based radio that uses glasses of water as an interface

We’re all used to turning a couple of knobs and pressing a few buttons to operate a radio, but have you ever played with glasses of water to change a radio channel? Probably not. Designers Tore Knudsen, Simone Okholm Hansen, and Victor Permild recently launched their art project ‘Pour Reception’. And it’s beyond anything you can imagine. Pour Reception consists of two internal speakers, an AUX input, a handy guide and two glasses that must be placed on the body of the radio. And no the glasses aren’t just to sip water from, though you could do that. The radio uses the two glasses filled with water as it’s interface!

[…]Pour water into the glasses, and the stereo starts! Transfer some water from one glass to another and you can change channels. Touch the glasses, and you can fine-tune the radio’s signal, eliminating distortion. Finally, pop a finger into the water to control the volume or to bring the radio to a halt!

This might seem like a scenario from an alternate universe, but the tech behind it is pretty common. Objects emit micro amounts of electricity, and touch tends to disrupt this and convert it into a signal. By using Tact library by NANDstudio (an open-source Arduino shield that turns any object into a touch and proximity sensor), the designers converted the radio platform, glasses, and water into different layers of a capacitive interface, allowing them to conduct minute amounts of electricity and transforming them into sensors. Utilizing a Wekinator (an interactive machine learning tool), various gestures such as touching the glass or dipping a finger into the water were mapped into commands for controlling the radio. The end result; a radio with glasses of water functioning as a “digital material interface”.[…]

Oh now that’s a fun way to combine radio and art! Obviously, this isn’t an RF radio–it either grabs streaming content or (more likely) uses pre-recorded content on an internal storage device. Still, I think it’s a creative little project and an ideal way to play with Arduino Tact library.

    I made a tuning condenser once by wrapping the glass in aluminum foil and a wire inside. adding water lowers the frequency. Has long term drift problems as the water evaporates changing stations was a nu sense. you needed a turkey baster to change the station.
