Google Tokyo Pendants | Iontank
2018-2019
The pendants were a complicated 3D lighting PCB design. They combined multiple board designs connected at different angles and hung off one cable. They use two different types of LED, a built in LED driver, boost regulator, and AVR Microcontroller to provide full animation and color temperature control over I2C. They were driven by a collection of Beaglebone Black’s running custom software which used the hardware I2C interfaces to translate websocket messages to I2C commands. They were installed in a constellation of over 100 with lengths of 16, 24, and 36 inches.
