This new version of my sound reactive pendant has a much more beautiful case design and richer colors while maintaining an impressive 4,000 frames per second. It has an adjustable sensitivity so it looks great reacting to sound from your phone or while you’re hugging a giant speaker at a concert. It also has a slow calming mode that cycles through the colors and looks great even when there’s no music playing.
This sculpture pulses slowly and smoothly, mostly in shades of blue. Gesture your hands above it to direct the colors to change.

This 3d printed sculpture casts beautiful shadows when lit from the inside with leds.
The sculpture reacts in real time to music in the following videos:

The next video is at normal speed, 30 fps. The one below it is displayed in slow motion, 240 fps, so you can see the fast, detailed response to the music. 9 seconds of the same song expands to 47 in the second video. The lights update 3,000 times per second and display in full 24bit color (16 million colors).

This glowing pendant reacts to sound, creating a dynamic light show. A video is below, but it can’t show all the detail. The pendant reads the audio levels and updates 3,000 times per second while the video is only at 30 fps. All this in full 24 bit color. An advantage of using LEDs instead of screens is they can update so much faster. No screen you’re looking at can convey the vividness of this light display. You must see it in person.

LED Poi draw beautiful patterns as you spin them around. Sensors in the poi change the light based on how they are moved creating a dynamic and unique performance.
Here is a close-up of the latest prototype
Electronic firefly automata self-organize into synchronized flashing swarm
Certain species of fireflies will synchronize their flashing in the wild. They do this by watching their neighbors and changing their own pattern to converge on what they see. This is an incredible effect to see in nature especially since there is no leader, they self-organize. They flock in time like birds and fish do in space.
This project aims to recreate this emergent behavior with a group of electronic fireflies. Each one is small enough to be pinned to a shirt like a brooch or a badge. It pulses its pattern on a green LED, broadcasts its timing on an IR LED, listens for others with an IR sensor and converges toward them. A small swarm will synchronize up in a minute or two as they come within visual range of each other, about 10m.
Now imagine dozens of these, worn by visitors as they move around a space, constantly converging on each other, being stirred up by new visitors as they approach each other. They work outdoors or indoors, in light or dark, but are obviously more dramatic in the dark.
The brains of the project is an Arduino micro controller, and the code will be open-source as well as the hardware. I will make the circuit board and cad files for the case available as well.
A swarm of synchronizing fireflies is cool enough on its own, but adding an RGB LED has made subsequent versions of this project into a more general purpose art platform. Color cycles through the rainbow can be synchronized rather than just flashes. They can be programmed to follow each other rather than match each other. They can broadcast their color along with their timing so that colors seem to pass around between them or converge on each other. All behaving independently as cellular automata, creating an emergent behavior as a group.
An exciting project, 5 robots for the play Heddatron, showed May 18 – June 9, 2012 at the Stray Cat Theatre in Tempe, AZ.
We designed and build these custom robot characters: [from left to right] Julie, Berta, Hans, Brack, and Billy. They drove around the stage, lit up to talk, and shook with excitement as their human operators executed complex choreography with them.
They were all custom designed and built in a month, making it through 14 performances without a malfunction.
Feel free to contact me with any inquiries about the design process, or if you want a set of robots of your own.
