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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
