Gorgeous wall art, 3D printed, soothing animations, soothing color palette, handmade paper. Created using software that lets the user control the lighting with a high degree of control. 3D printed frames and bezels harmonize with handmade paper
We were traveling to Austin, TX for a regional Burning Man festival and wanted to make flashy LED wearables to impress our friends. Furry material diffuses the LEDs nicely and the flexible LED strip has held up to a fair amount of abuse. I programmed the animations and built the hardware. Marissa made the scarves.
The animation engine is somewhat sophisticated. It is able to have multiple animations playing at once so they can move through each other adding together like waves when superimposed. FastLED then handles displaying each frame on the strip.

individually addressable LED strip – expecting 5v for data and power but 3.3v to 3.7v from the LiPo battery seems to work fine
lithium polymer (LiPo) battery 3.7v nominal, 4.1v max
I did a quick Christmas present for my brother. He found this old lamp and I converted it to LED with a micro-controller to do PWM dimming.
The underside. Control knob at right is read by the Arduino Pro mini at left. Transistor at top of circuit board forms a constant current source with current set by large rectangular resistors and is switched on and off to do PWM by the Arduino.
