48 display controllers over three I2C buses; 288 four-digit 18:88 clock displays (25 segments per display); full 8-bit PWM grayscale control.
I built a mega-display, using the multiple I2C buses of the Raspberry Pi 4 and my own custom PCBs. It's housed in an aluminum extrusion enclosure with my 3Dp clips. Because I'm an artist I use it to show imagery tangentially related to the Singularity: inevitability of automation, machines replacing humans, clips from Metropolis, nice heartwarming stuff like that. It's called "One-to-Many."
If you are in the DC area, you can come see it in person at VisArts in Rockville, MD, from September 3--October 17, 2021.
