  1. 1. Question
  2. 2. http://lilypadarduino.org/
  3. 3. https://github.com/web-goddess/commaclubcushion
  4. 4. Capacity for AAA battery: 860-1200 mAh at 1.5V x 1.5 = 1300-1800 mWh Max power dissipation for each LED: 120mW Each comma has 10 LEDs, so 10 x 120mW = 1200mW All three commas = 3 x 1200mW = 3600mW 3600mW / 1500 mWh (taking average) = .42 hours = 25 minutes Ignoring the power to the Arduino and loss in the conductive thread. :) How long will the battery last?
