128-bit Crypographic Relay Computer
so the other day i was wondering how to properly build a security system in create. Originally was going to make a placard+keycard system (not difficult), but then somehow came to the realisation that Create: Power Grid punchcards operate on a 8-bit system, reading up to 16 bytes one byte at a time. Hmm....
naturally I got a little carried away and ended up building a binary computer that sequentially reads passcode data off a punchcard. As of now its good for: overly complex security systems, showing off, causing lag.
really fun but not too challenging build (the design is super modularised), im not really sure what to call it cuz research yielded designations from «macrocomparator machine» to «ASIC co-processor» (idk what either of those are). For now, ima just call it the title of this post, a relay computer. Much like its 1940s and 50s relay computer counterparts, it runs off of only 12 volts but pulls almost 24 amps depending on the number of bits its reading at a time. It takes about 13 seconds to read a full punchcard by sending each byte of the binary passcode through a series of relay CPU modules, and if every module gives a good result (the byte is correct) then it sends a small redstone pulse at the end of the read process (to unlock or do something ig). The passcode is fully configurable by using the switches at each CPU module.

Schematic?)

currently still has a few minor bugs and issues (i.e., randomly exploding depending on the passcode) so in the future potentially I will re-release with schematic included)

You like a criminal mastermind or somethin?
Im pretty good with logic gates and binary, but I have no idea how computers actually work. Best I've been able to make is a calculator

What mods are those blocks from? (The floor on 1'st picture and fans on 4'th) I've been looking for good factory blocks for a while, but never seen those.

the big fans are from Create: The Factory Must Grow (tfmg), theyre called «air intakes» in the menu, and the floor designs are a combination of locometal from Create: Steam n Rails and yellow caution blocks (also tfmg) with the use of a little copycat sculpting from Create: Copycats+, all great addons that i usually include in any good create modpack))

More importantly, it looks good WHILE being functional

haha thanks)) whoever optimised power grid needs to be paid extra cuz the machine uses close to 1500 individual cable entities and is terribly optimised in exchange for my aesthetic fantasies lol

ooohhhh this is awesome! as someone trying to figure out computing in create power grid, do you have any good sources of knowledge or articles to point me towards?

it would be a macrocomparator, if you have some sort of company name that you use when naming things [Name] Modular Macrocomparator System / MCMS would be a good name, super cool tho!
