I'll try to summarise all the steps I'm taking to build a usable flipdot display, including :
- Understanding how it works
- Making a prototype controller
- Tweaking the controller to improve results, refresh rate, efficiency...
- Designing a PCB for the final controller
- Code a useful firmware to display stuff
- Pack the whole thing in a nice enclosure
- Enjoy watching dots flipping all day long
It's a long ongoing journey, stay tuned !
