Does anyone know how to make an eggcrate scoreboard with LED modules and Raspberry Pi?

Nobody is going to be able to answer this for you off the top of their head, especially with the plethora of information you have provided.

Honestly, seriously, this is a discussion you would be better served having with ChatGPT. This is the kind of thing it excels at.

Someone has been working on this over on BAV. ChatGPT certainly couldn’t have spat this out.

Yeah, I've seen that, but right now his 3d print is down and the project is on hold.

3D printing is not rare in the year of our lawd two thousand and twenty-five
This signature is currently under construction.

How authentic do you need it to be?

You need to settle on the type of lamp to use. This will determine the voltage used to drive the lamps. LED's would be best but will be expensive. The original readouts used type 1820 lamps driven at 28 V and were WAY TOO BRIGHT and were usually on a rheostat. The characters were formed by a diode matrix.

From memory I can tell you the holes for the lamps were 5/8" in diameter with about 1/16" between holes.

The readouts used on Twenty One present an interesting case because solid-state diodes did not exist yet. You could use a 12-position rotary switch and hard-wire the character forms to the lamps.

Have a look here:

I'm not sure Raspberry-Pi is the right device to use for this.

It isn't; it's way too much machine, unless you're talking about something like a Pico, and even then I suspect it's too much, although at $10 why the hell not. You could probably get away with something ESP32-based considering you're effectively talking about controlling either a) a series of 35-light long LED strips (and white LEDs would be plenty bright even with 3D-printed diffusers in front of them) or one single strip that is 35 x (however many digits you want it to be) lights long that you would need to inject power into at intervals. (If I can run a 6,144 light matrix (really three 2,048 strips, effectively) off of one ESP32, an eggcrate should be no problem.)
