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

Many thanks to SWLing Post contributor, David Korchin, who shares a link to this article on Yanko Design:

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.

While Not Directly Radio Related . . .

While not directly radio related, this was too amazing not to share (so forgive me in advance! There is an Arduino involved, if that helps?!)

The video above is of a robot which can solve Rubik’s Cube in about 1 second.

I will not embarrass myself in telling how long it takes me to solve it . . . .

It is, however, easy to see how radio hobbyists could find these Arduino boards quite intriguing!

Adafruit Industries: an amazing resource for electronics experimenters

SWLing Post contributor, Richard Langley, writes:

In a recent blog posting, you mentioned the use of Arduinos in the radio hobby. Those of us who have experimented with Arduinos (and Raspberry Pis, etc.) likely have come across Adafruit Industries when looking for hardware bits and pieces to use in our maker activities.

There is a great article on Limor Fried and her company in the latest issue of the IEEE news magazine “The Institute” and it’s also available on line:

And there’s a short video up on the Web where Fried explains the company’s purpose and philosophy:

Richard then added:

[Here is a] cute Adafruit video introducing the concept of (radio) frequency to kids:

Very cool!  Thanks so much, Richard, for sharing this. Adafruit looks like not only a true community player, but a comprehensive source for the electronics experimenter! My daughters love the Adafruit video; now to dig up all of the previous episodes!

I’m planning to learn more about Arduinos and my RaspberryPi this winter, so I’ll keep Adafruit bookmarked!

“Enjoy your blog. I have been reading it for years. [H]ere is something your readers might be interested in that I mentioned in my blog today:

Very cool! Goes to show that there are a countless number of applications for the Arduino system to be used with amateur and shortwave radio.
