Bundle up this winter by replacing your coat's buttons with 3D printed NeoPixel buttons, powered by GEMMA, Adafruit's tiny wearable electronics platform.
Get the parts and circuit diagram for this on http://learn.adafruit.com/
Print the buttons in using PLA filament for great light diffusion, and stitch the base pieces to your coat using regular thread.
Then, starting from the pocket, stitch power, signal, and ground connections between GEMMA and the chainable RGB NeoPixels using conductive thread. Don't sew them so tightly that you can't fasten the button, but not so loosely that the button can twist and short any connections.
To power the circuit, stitch a lipoly or alkaline battery pack into the coat's pockets. Code up your own unique color patterns and share your project with us on the weekly show and tell. Check out our full tutorial on http://learn.adafruit.com/
Adafruit was founded in 2005 by MIT engineer, Limor "Ladyada" Fried. Her goal was to create the best place online for learning electronics and making the best designed products for makers of all ages and skill levels. Since then Adafruit has grown to over 25 employees in the heart of NYC. We've expanded our offerings to include tools, equipment and electronics that Limor personally selects, tests and approves before going in to the Adafruit store. We pride ourselves on having great prices, the best customer service, technical support and fast shipping. We hope we can assist you on your journey of learning - At Adafruit we celebrate engineering happiness!
