The the Screaming Circuits / Sunstone Circuits “You Do You” electronic lapel pin is a 1.3″ x 1.6″ lapel pin powered by a single CR2032 coin cell (yes, batteries are included in the gift pack at the OSHWA 10th anniversary summit). It’s driven by a Microchip PIC18F46K22 microcontroller, an NXP MMA8452 MEMS accelerometer, many 0402 LEDs and a bunch of 0201 passives on a 5 mil trace and space PC board from Sunstone Circuits.
It’s perfect for the shy person wishing to avoid eye contact. Simply clip it to your lapel. When you go to shake someone’s hand, the MMA8452 will register the movement, causing the YDY LEDs to light up and distract the handshakeee, diverting their gaze from your eyes to your lapel. Extra shy people may clip it to their shoelaces for even greater gaze avertment.
