Automated tile fun

[Thanatos994]

I returned to ONI for the automation update, and stuck around a bit longer because the corona quarantine has given me too much free time.

With that free time I decided to try and find the most complicated thing I could do with the new automation tools. Creating a pixel board that shows letters is what I ended up doing, not sure if it's been done already but I figured I'd share my implementation at least!

Here is a video of the set up showing the letters A, B, and C. The map didn't really have room for more! There may be an obvious more practical way to do this that I missed, but the complication was the fun for me anyways.

My build is based on this unit:

There are two important features to the unit: the filter system which rotates through the outputs on the signal distributor, and the switch system which stores the bit states. Switches are the only way to store information permanently on an automated circuit that I know of. The filter system is more complicated, so I numbered the parts.

1 is a 'flush' signal to the reset ports of all the memory toggles. Its memory toggle receives the green signal directly from the start switch, and the filter on its reset port is set to 0.1 seconds.
2 is a 'pulse' circuit, which limits the time that the green signal from the start switch is sent. It does this via the filter, which is set to 1.2 seconds, thus the length of the green signal is 1.2 seconds.
3, 4, and 5 together are the filters which let the signal distributor rotate through its outputs. The input to the signal distributor turns green immediately, when the selector inputs are red-red. Then, 4 turns green, with a filter time of 0.3 seconds on its memory toggle input, for green-red. Then, 4 turns red, with a filter time of 0.6 seconds on its memory toggle reset, and 3 turns green, with the same filter time, for red-green. Then 5 turns green, with a filter time of 0.9 seconds, for green-green.

Here's the save file if anyone wants to play around with it:
