Glowy necklace made from headphone cable #WearableWednesday
Thanks to Dale for sending in his wearables project! View the full tutorial on Instructables.
For some time, I’ve been contemplating how I can make an intelligent, micro-controller-powered necklace, but I hadn’t been able to figure out how to make it small enough to be attractive. Even if a microcontroller is small enough to fit in a necklace pendant, the battery to power it usually isn’t. Then, I had a revelation: why not store the microcontroller and battery behind my neck/hair, where nobody can see it, and connect the necklace pendant to the microcontroller via a headphone cable? Modern headphone cables might contain 3 or 4 über-thin wires, so I would be able to move power, ground, and two data lines from the microcontroller behind my neck to the pendant hanging in front. Here, I’ll show you a little bit about my experiments with headphone wires for wearables.
Flora RGB Smart NeoPixel version 2 – Pack of 4: What’s a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable – so you only need 1 pin/wire to control as many LEDs as you like. They’re easy to sew, and the chainable design means no crossed threads. Read more.
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.
