A custom wireless system built for Craftwife. The LEDs are to be sewn into real ties. There are 6 red LEDs per receiver and each led can be dynamically controlled (PWM 0-255). All receivers run on battery (AA 3.6V lithium) and keep in contact with the transmitter using 2.4GHz wireless transceivers (Nordic nRF24L01+). The maximum working distance is about ~80m (line of sight).
The transmitter talks to SuperCollider via the RedTieMaster
and RedTieSlave
classes (USB-Serial 115200 baud).
