A musical chair to play the game of musical chairs, with random household sounds. Made using Adafruit's Circuit Playground, Processing, Pure Data and a 3D-printed chair.
To use random household sounds, you need to record some. Grab a recording device, like a camera or your phone, and record some weird sounds.
The next step is making a chair. I chose to 3D print this one I found on Thingiverse, which I edited to make space for the Circuit Playground.
3D-printed chair
The Circuit Playground has all sorts of cool sensors, and the idea is to get the data from these sensors to Pure Data, which will make the sounds.
The straightforward way to do this, is to send the data from the Circuit Playground straight to Pure Data via serial communication. After many, many failed attempts and no proper tutorials on how to accomplish this, it was time for plan Z.
In this elaborate plan Z, the data is sent from the Circuit Playground to Processing via serial communication. Processing then sends this forward via OSC to Pure Data.
It's a bit of a loop, certainly a hassle, but the only way I managed to get it working. Tips on how to get the serial data to Pure Data would be highly appreciated.
The code for all of these parts can be found in the attachments below.
Put it all togetherIt's time to assemble all the parts! Upload the code to the Circuit Playground, attach it to your computer and run the Processing and Pure Data scripts at the same time. As if by magic, this should work!
You'll be the life of any party with this awesome chair!
