Comment on Why NEMA 1-15 Power Cords Still Matter for Everyday Devices?
tal@lemmy.today 2 weeks ago
The NEMA 1-15 power cable becomes the most important item in the room when people discover their specialized devices cannot recharge without it. It is frankly hilarious how much we obsess over liquid cooling and fiber optics while our daily sanity relies on a design that has barely changed since the dawn of the lightbulb.
Only peripherally-related, but on that note:
-
The most-common lightbulb socket in the US (the “Edison screw”) dates back to 1909.
-
The 1/8-inch headphones jack isn’t identical to the original standard, but it’s a direct decendant (and electrically-compatible with) the 1/4 inch mono headphones jack from (checks) 1877. Since that time, we’ve had variants with more rings (stereo, microphone, balanced audio) added and the size reduction to 1/8-inch for smaller devices. But the basic standard has been around for quite a while.

There’s also the Belling-Lee connector. It’s been around since 1922 and is still commonly used for radio and TV antennas in Europe.
