working fully (except that one dude, last row. fixing it as i write this) and i love everything about: the aesthetic, its weight (it's glass, so it's got some heft to it) and just running on 5v. low power, too! now to some programming and this baby is ready...

How does this work? What are you using here? Genuinely interested.

a single PCA9685 PWM servo driver can pulse 16 LCDs. multiply this by four and you have four drivers and 64 LCDs. controlled by a single ESP32-S3. all mounted on a 31x31cm custom PCB.

also the drivers are over I2C so they are easy to daisy-chain. i think this is the most economical way to do this. other options: driving PWM directly form the GPIOs, but then you are limited by your GPIOs of the uC. another option is to use a shift-register (binary only. no PWM)

This had to have taken so much patience and attention to detail. I love everything about it.

@mannay @xercyn whoa, this is great! someone has mentioned this before but i was only able to find a still picture. i knew already that this was very impressive, but seeing it as a video really shows the scale of the installation :o

F2 and D1 aren't working, isn't just D1 on the last row.
