An interesting piece about the 3.5mm audio connector from the BBC:
The 19th Century plug that's still being used
"The 3.5mm headphone jack is essentially a 19th Century bit of kit - it is a miniaturised version of the classic quarter-inch jack (6.35mm), which is said to go back as far as 1878."

- kirrent 11y agoI still remember watching WW2 films and seeing scenes of phone exchanges where people were switching manually ussing the quarter inch jack. It was surprisingly thrilling. I was working during the day at a place where I sold the same type of jack that was in use for similar purposes all the way back in world war 2. I had no idea their history went back so much further than that.
- rootbear 11y agoI have a bunch of old electronics parts inherited from my father, who was a Ham and an EE. There are a few old quarter-inch phone plugs, from the 30s or 40s, in the collection, with classic Bakelite casings. They work just fine in modern equipment.
