Making

FORM
The bracelet was designed using Rhino.  I 3D printed both the band and main component housing. Using the hard plastic bracelet forms as a positive I cast a silicone mold which I used to produce the final urethane bracelets.

CIRCUITS
I used a Seeeduino Film flexible micro controller and bluetooth frame for their compact size and compressible form factor.  I also used two ultra bright tricolor LEDs for the indicators and a small LiPo battery to power everything.

SOFTWARE
I wrote a simple service application for Android which would send points to the bracelet as usage increased.  I also wrote an accompanying sketch for the microcontroller using Arduino which changed the color of the LED indicators as the number of points increased.
