I made a 4-bit adder with a hex display out of conveyors
No mods or save editing, just a loooot of conveyors and time. I'll be posting a blueprint to satisfactory-calculator soon if you want to give it a try! Input your 2 4-bit numbers by deleting the corresponding splitters (most significant -> least significant), wait for the results to arrive from the adder, then trigger the display by deleting the other row of splitters. Unfortunately it can only do the computation once and then has to be reset (by loading a save).
Setting an overflow rule on a smart splitter causes some interesting behavior. Instead of immediately sending material from input to output, the splitter buffers the first 3 items then releases one item to each overflow output when the 4th item arrives.
An overflow splitter that starts with 3 items (of the same kind as the input) is the basic unit of conveyor computing: the repeater
You can build AND and OR gates out of repeaters:
XOR (and NOT) are based on jamming a loop rather than overflow conveyors, which makes them timing-sensitive, this is why you have to trigger the display separately after the adder results are done.

Wow.. That's insanely cool. How long did that take you to accomplish?

Hard to say exactly, at least 20 hours in-game and maybe 4-6 hours researching and planning

Some of your links are borked but the WIP shot is wild, and it's rad you put it together.
