Summary:       Made a wearable Small Necklace or pendant with custom Tear shaped PCB and Attiny13A.The goal here was simple, to make a small Blinky board that can be attached to a chain so we can wear it like a locket or pendant.There are a total of 24 LEDs in this Pendant, I've divided LEDs into pairs of 4.This means 6 LEDs are connected in parallel and they are driven by a single AO3400 N channel mosfet. there are a total of 4 of these which control 6 LED segments each.Pretty simple stuff.
