‘Snowfall Dress’ with 440 NeoPixels Animates Falling Snow, Color Fading Patterns #WearableWednesday

We love how what starts with a question leads to a successful project for an event or installation! In this case The Crafty Avenger asked a simple question, “what board to use?” to control 440 NeoPixels. The answer was simple: Flora. And thus the ‘Snowfall Dress’ was made!

This dress is meant for a stilt walker or performer in a large crinoline. We are testing the snowfall pattern in this video.

I used about 440 WS2812b LEDs + one 100foot string of fairy lights to create this dress. I used a Flora Board to control it and 4 large batteries to power it. Not lite by any means but bright and pretty for a good long time.

This dress was designed to run a snowfall pattern for a snow queen costume. The design of the LED set up was designed to be reprogrammed and flexible. This is the test for the color diffusion.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
