NeoPixel Skirt with Pro Trinket #WearableWednesday
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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
