New Guide: Build a NeoPixel Crystal Chandelier with Speed & Brightness Control

DIY crystal chandelier

Take a look at the latest guide from Erin St. Blaine: build a three tiered chandelier with hanging DIY paper-craft crystals that light up with pixels inside. Easily add your own custom animations using CircuitPython and the LED Animations Library. This guide takes animated lights a step further, adding a rotary encoder knob that controls the brightness or the animation speed of the pixels, and also acts as an on/off switch. From the guide:

Floating crystals and glowing lights are a match made in heaven. This project combines a wide variety of skills and tools into one lovely project. Make a gorgeous hanging lamp with sparkly beads, glowing crystals, live edge wood and of course, lots of NeoPixels.

My chandelier is unique, and designed to show my personal style. Since you, dear reader, have your very own unique style, this tutorial will focus on giving you the tools to design and create your own one-of-a-kind bespoke hanging lamp. This tutorial will provide source files and ideas, and give guidance on how the electronics fit together.

This tutorial will also get you started with customizing your own software animations. The sample code uses CircuitPython and the delightfully easy to use LED Animations Library by Kattni Rembor. This code gives you a framework that allows speed and brightness control using a rotary encoder knob, so you can adjust the lighting to suit any environment or mood.
