This Neopixel Crystal Chandelier with CircuitPython Animations and Speed Control guide is from the Adafruit Learn system!
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.
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.
University of Houston‘s associate professor of mechanical engineering, Jae-Hyun Ryou with assistance from post-doctoral researcher, Nam-In Kim, has led to the creation of a non-invasive wearable capable of easy and continuous measurements and monitoring of eyeball movements. The sensors use a special material that generates electricity when it bends and functions when combined with a hand-held display and computing device.
A University of Houston engineering team has developed wearable sensors to examine eye movement to assess brain disorders or damage to the brain. Many brain diseases and problems show up as eye symptoms, often before other symptoms appear.
You see, eyes are not merely a window into the soul, as poets would have it. These incredibly precious organs are also an extension of the brain and can provide early warning signs of brain-related disorders and information on what causes them. Examining the eyes can also help track the progression and symptoms of physical and mental shocks to the brain.

Researchers at Northwestern University were able to witness and record the formation of new water bubbles. The research is a result of experiments with palladium.
Using the new technology, Dravid, Liu and Koo examined the palladium reaction. First, they saw the hydrogen atoms enter the palladium, expanding its square lattice. But when they saw tiny water bubbles form at the palladium surface, the researchers couldn’t believe their eyes.
