What is it?

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).

Why did you make it?

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.

What makes it special?

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.
