Earrings with LED's designed for Saint Patrick's Day. The different patterns are controlled by an ATtiny84a and programmed with the Arduino IDE. These earrings are powered by a CR1225 coin cell battery, and will last at least 3 days, and up to 2 weeks (depending on the pattern). A button on the back of the earring can be used to select different patterns, or to turn off the device.
These earrings can be programmed with the Arduino IDE, using a SPI programmer (for example the Arduino UNO as programmer).
Adding some more variances to the LED earring family. The first earrings (Spiral) were such a success, so I used that same concept to light up the leaves on the shamrock. I also fixed some of the issues I noticed on the earlier designs.
The earrings are entirely assembled by hand. I use a stencil and reflow oven to install the components on the font, the back is done with a soldering iron. The Arduino IDE is used to program the micro-controller. To conserve energy, the ATtiny84a is in sleep mode, 99.9% of the time. It only wakes up to determine which LED should be turned on or off before entering sleep mode again.

California STEAM was started in the summer of 2017 in Stockton, CA by Alicia and Sander van de Bor. They added Art to STEM (Science Technology Engineering and Math) to create STEAM.
STEM and STEAM education is a growing necessity to meet the future demands of STEM jobs in the upcoming decades. These jobs are required in almost every field, from manufacturing to medical.
California STEAM develops creative solutions for all ages. Their classes are taught at several locations throughout Stockton (libraries, Mexican Heritage Center etc.)
The products developed by California STEAM are a combination of Art and Technology. These are designed to motivate young makers to get more familiar with electronics and programming. These young makers are the engineers of the future.
