redTie

custom wireless system built for craftwife. the leds are to be sewn into real ties (update 090428: now done - http://www.youtube.com/watch?v=QUGKfC0SYck). there are 6 red leds per slave and each led can be dynamically controlled (pwm 0-255). all slaves run on battery (AA 3.6v lithium) and keep in contact with the master using 2.4ghz wireless transceivers (nordic nRF24L01+). the maximum working distance is about ~80m (line of sight).
the master talks to supercollider via the RedTieMaster and RedTieSlave classes (usb-serial 115200 baud).
