We assume [Michelle]’s seem-reactive rib cage lamp turned out fantastic, and the photographs and facts around how it was designed are similarly superb. The lamp is manufactured of carved and waxed wood, and inside of is a bundle of LED lights capable of a range of unique shade palettes and patterns, including the capability to react to seem. Each individual rib cage really should have a occasion manner, immediately after all.
Turns out that creating very good rib cage parts is a larger problem than a single may possibly believe. [Michelle]’s technique was to use an anatomical 3D model as reference, tracing just about every piece so that it could be reduce from a flat sheet of wood.
The resulting flat items then get assembled into a stack, with just about every rib pointed downward at a around 20 degree angle. This method is a neat hack in by itself: instead of drilling holes all at specifically the identical angle, [Michelle] simply designed the holes two times the diameter of the metal rod they stack on. The result? The parts angle downward on their very own.
The LED lights is itself a good piece of work. The primary composition will come from soldered stable-core wire. The RGB LED strip receives wound all around that, then strengthened with garden wire. The end result is an atomic-hunting composition that sits inside of the rib cage. An ESP32 development board drives almost everything with the FastLED library.
Code for almost everything, together with the audio-reactive worky bits, which rely on an INMP441 I2C microphone module is all offered on GitHub. And if you want to make your individual seem-reactive art, make guaranteed to test out these arms as effectively.
