My first wearable with multi-colored pixels! 27 multi-colored pixels (2 LEDs per pixel) are strategically placed on each earring (104 LEDs per pair) by using three golden ratio spirals. These 3 spirals create mesmerizing patterns in different colors. This piece of art meets all the needs of the math fanatics, tech guru's and EDM lovers that are looking for a wearable that makes them stand out in the crowd. Literally in the heart of this earring is a powerful micro-controller. Power is delivered by the two size 13 zinc-air coin cell batteries. These batteries are commonly used in hearing aid, and widely available. On the back of the earring a push button can be used to change settings. 6 different modes are available:
And there is an option to change the colors as follows:
Size: 28mm (1-1/8"), 47mm from top of hanger
Weight with batteries: 3.9 gram (0.14 oz)
Batteries: 2x size 13 zinc-air hearing aid batteries
Battery life: 300+ hours
I have been experimenting with different earrings designs, but the non-representable designs (like the Spiral and Fibonacci earrings) are just the most fun to design and program, and very popular. For this latest design I wanted to experiment with multi-colored LED's. In order to blend the two colors (red and green in this case) the PWM outputs on the ATtiny416 were used. Using the TCA to control the PWM outputs in IDLE mode was actually a very effective way to control the LED's, and I was able to blend and fade the different colors. Definitely continue with using the timers to control the LED's directly on PWM pins on my next designs.
The entire design is a 6X12 LED matrix. The 6 anodes are connected to the 6 PWM outputs on the ATtiny while the 12 pins are connected by digital pins to control the cathode side of the LED. Theoretically the 6X12 matrix could control 72 LEDs, but in this design I decided to use 54 LED's only.
