To some, it’s the instrument that reminds us of one of popular culture’s most famous theme songs. To others, it’s the confusing flailing of arms to create music. And to others still, it sounds like a medicine or a small rodent.
In order to help their visitors better understand the origin of the theremin, Australia’s MAAS Powerhouse Museum built an interactive exhibit, allowing visitors to get their hands on, or rather get their hands a few inches above, this unique instrument.
As advocates of learning by doing, the team didn’t simply want to let their museumgoers hear the theremin. They wanted them to see it too. So to accomplish this task, they chose a BitScope Blade Uno, along with a Raspberry Pi, BitScope, and LCD monitor.
BitScope go into a deeper explanation of how the entire exhibit fits together on their website:
The Raspberry Pi, powered and mounted on the BitScope Blade Uno, provided the computing platform to drive the display (via HDMI), and it also ran the BitScope application.
The BitScope itself, also mounted on the Blade, was connected (via USB) to the Raspberry Pi and powered by the Blade.
The theremin output was connected via splitters (so they could also be connected to a sound amplifier) and BNC terminated coaxial cables to the analogue inputs via a BitScope probe adapter.
We’d love to see a video of the MAAS theremin in action so if you’re reading this, MAAS, please send us a video. Until then, have this:
