Look what just arrived in the mail– Blinky AVR Earrings!
Not long ago, Rick posted on twitter about the ATtiny84 blinky earrings he had made, inspired by my voltage regulator earrings (which I now fasten on with the appropriate phillips screw).
Four blue LEDs blink in sequence, powered by a CR1220 battery. The board is traditional OSHPark purple, with an ISP header for convenient reprogramming. They’re lighter than they look and quite comfortable.
Thank you, Rick! I know what I’ll be wearing to Maker Faire!
