I first saw a power button necklace posted on Pinterest, it was called an iNecklace which can be found at
Adafruit, it is made from CNC machined aluminum and the light gently pulses. But with a price tag of $75 I opted to try to make one myself. Mine is what you'd call the poor women's power button necklace, it was put together from stuff I had lying around the house. Although my necklace is plastic and the light doesn't pulse, it cost me hardly anything to make and I put it together in one afternoon.
that and im to lazy to look through my old electronics for a good one.:P
nice work, and have you ever thought about making plastic custom buttons that you can trim out a design with an X-acto knife?
ex: Doctor Who Logo
If I had access to a 3d printer or laser cutter, I could probably make a bunch of these. I like the idea of a Doctor Who one that would be really cool, or batman even.
Nicely done, clear instruction and very helpful comments from many.
Then you could screw in the backing to take the battery in and out. Or just modify it to turn on and off from the pressure of screwing in the backing. That way you can just leave it unscrewed when you're not wearing it and extend the life of the battery.
Now, to find someone who really wants a power-button necklace...
I am always looking at something cool but too expensive and saying to myself (in exaggerated tones, of course) "Why, I can make that for a FRACTION of the cost!"
You did it, girl!
