Luminator FlipDot Board

In this project I fully rebuilt a Luminator FlipDot display Board. Flipdots are small disks that flip to display two colored sides.
Compared to LED displays, they do not take any power while they are "on" or "off", they only take a pulse of power when switching.
Of course the disadvantage is at night you still need to light them up. Flipdots are more of a novelty due to their mechanical complexity compared to LEDs.
These displays were typically used in busses to display route information. Luminator is still around today but they have moved to LED displays :(

The model that I got is a MAX 3000, I didn't want to decipher the serial protocol, I didn't like the casing, and I did not trust the old electronics.
So I decided to start from scratch. The only thing reused in this project were the four 16Rx28C FlipDot boards.
I designed a PCB, new case, and software. The full display is 16 Row x 112 Columns.

The PCB essentially has two series of shift registers that control a high side and low side transistor for each row or column.
Each flipdot essentially needs its' own H-bridge so to write the display only one dot can be toggled at a time.

All of the project files are public in this Github repository.
