Matt wrote in with his article for the instrument he to his local Dorkbot music event in Columbus last week, he writes –
This project started as an instrument for Sonic Tooth, our local Dorkbot music event. I was looking for something where you could put any sound into the mix.
As an instrument, it’s basically a mash-up of an answering machine and a megaphone. It ends up being a small package with a loud punch, so you could use it to play the same sample over and over (and over…). It uses a solid-state recorder with a 120 second capacity (Winbond’s ISD25120)
The really cool potential that I didn’t explore in this project is the ability to control the recorder via a microcontroller. It looks like the recorder’s memory is addressable via a 10-bit address setting. With that, you could have the resulting playback be driven by any number of environmental stimuli. I was looking at using an Amtel ATiny13 to drive it, because I only really needed a 4-bit address space, leaving 4 ADC lines for input. But, that’s all to come still.
