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.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
