Storm Glass: A Spherical Swirling Storm on Your Desk

Great Circuit Playground Bluefruit project from grajohnt up on Hackster.io.

Rheoscopic fluids allow the currents and turbulence in fluids to be seen. They’re typically made with mica, a mineral that forms small shiny flat plates that easily moves within a fluid.You can find them in science museums (such as the Glasgow Science Centre), or as art displays (most famously, the Kalliroscopes of Paul Matisse)

I’ve always loved the way the fluid moved within these displays, and I wanted to build something that didn’t require interaction. I also thought it would be interesting to light them from within or underneath, rather than relying on light reflecting off of the mica plates.

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.
