This Spectrum Analyzer Sputnik Shines a Light on the Sounds Around

Looking like something straight out of a sci-fi film, this steampunk Sputnik sculpture shines out in response to the sound around it.

Mohit Bhoite is back again, and this time with a “stellar” example of his circuit crafting skills, in the form of a satellite-inspired spectrum analyzer sculpture.

Looking like something straight out of a sci-fi film, this steampunk Sputnik has something of a Dark Side of the Moon vibe as pictured above, and perhaps that’s in part down to the dazzling light show it is capable of putting out.

Not content with pre-programmed pixel patterns, Bhoite has taken an interesting direction, in giving this sculpture the ability to listen to the noise around it, and respond in its own unique way.

In the previous photo with the lights out, some of you may have noticed that felt-faced, silver cylinder at the center of the triplet of WS2812 armatures.

If you’ve ever taken on a project with sound-reactive capabilities, you’ll recognize that as an electret microphone, a device that produces an output voltage that varies proportionally with ambient noise levels.”
