LED Circuit Earring #WearableWednesday

Blinkring LED PCB earrings by Bertho:

Sometimes I get impressed by the ideas that come up at the local hackerspace. We have a member, Inger, who has been doing nerdy jewelry workshops, where all kinds of stuff is made from old computers. Making earrings from harddisk components, a snail from a aluminium cooling block with fan-grids and wires, a christmas tree from harddisk PCBs and SDRAM-DIMs. You name it and it gets made.

Inger is no engineer or technician. She held a screwdriver in her hands for the first time at the hackerspace. She is a quick learner and has a unique perspective on things. She was trying to put together a LED on a harddisk-spindle mount, to be used as an earring. As a non-tech, I explained her how to make connections and the like. All the work, however, was done by her.

Inger’s funny piece inspired me to design a more advanced piece of nerdy jewelry. I had seen Mats’ fabulous job of “hiding” a battery inside a PCB on Dangerous Prototypes. That can be used for an earring as well. And surely, you can also just hang it around your neck as a nerdy hanger.

The concept is simple: make a round PCB with a large hole milled out in the middle and put some LEDs and a micro-controller on it. Program a blinking party and done.
