Thanks to Will for sending in this great NeoPixel skirt project! He writes:
A Trinket Pro pushing about as many Neopixels as its little memory can stand (and about as many as my wife can stand carrying 🙂
160 WS2801 LEDs, a Trinket Pro and a 10DOF IMU. Powered by a 2200mAH 11.1V LiPo through a 10-amp, 5V-output battery-eliminator. Gets about 1.5 hours in mixed modes, more if we keep it in the less power-hungry modes.
There are a couple modes that I didn’t capture well in the video (for example, the snow accumulates over time at the bottom of the skirt), and outdoors where the compass works better, the grid is compass-referenced so the display stays “stationary” even if she turns within it. Resets are cued by the rate gyro, at rates > 2.5rads/second. Modes switch randomly up or down in a ring to avoid resets duplicating the previous mode, while also avoiding a predictable order.
At this point it’s pretty much up against the Trinket Pro’s SRAM limit. Might move to a Teensy next.
