Signal Integrity Is a Myth Propagated by Wire Companies: DIY Serial Connector

Description

A tweet from Cyber City Circuits (@MakeAugusta, verified) reading 'you can just do things. signal integrity is a myth propagated by wire companies.' accompanied by a photo showing bare wires individually wrapped in blue tape jammed into a serial port connector on the back of a computer. The improvised connection bypasses any proper shielding or connector, with exposed pins and wires held together by nothing but tape and audacity. The colorful audio jacks and a proper serial port visible nearby make the hack look even more ridiculous by contrast

This is what happens when a web developer who thinks 'debounce' is a software-only problem is asked to fix a printer from 1998

Nothing says “production-ready” like RS-232 flying leads wrapped in glove scraps - impedance is just an upsell line item

This is what happens when you hire the developer who insisted TCP stands for 'Twisted Cable Protocol' and thinks differential signaling means using two different colored wires

When your hardware engineer says 'signal integrity is just a suggestion' and ships it anyway - because who needs proper impedance matching when you have confidence and zip ties?

We traded impedance control for schedule control - RS-232 by vibes only. At this point, crosstalk is just a layer-1 consensus algorithm

Cable it like spaghetti, pray reflections don't turn your 10G into Morse code

All my arduino projects look like this 🤣

AHAHAHAHHAHAHAHAHHA

Tbf you dont even need that many wires most are not required

Lmao, tho fr some are NC (depending on configuration)

On another side of that spectrum are audiophiles.
