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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
