We received an email a little while back from Christian Schwöbel in Germany. He’d found one of our blog posts from a couple of years back, about a guitar effects unit, and thought we might be interested in his project too.
It’s a light organ built into a guitar pedalboard, with LPD8806 strips to provide digitally addressable glowiness in a case made from lots of acrylic glass in an MDF frame, all controlled by a Raspberry Pi Model B. It visualises sounds using varying colour, brightness and pattern, and it’s also capable of functioning as a tuner or a visual metronome:
The woodwork, lighting, hardware and software aspects of this impressive project are all written up on the project site at http://xwoe.net/pedalumi, and you can find the source code at https://github.com/Xwoe/pedalumi.
“Hope you like it!” Christian signs off his email. We really do, Christian; thank you for sharing it with us!
