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.
