But we still use keyboards with the same form factor that was dictated by mechanical typewriter constraints. I'm not talking about QWERTY but the whole device. Think about your unnatural posture when writing both hands on a keyboard. We could do a lot better but for some reason things like split keyboards haven't caught on. Path dependency is one tremendous force.
It was even possible to generate the pulses by hand, by flashing the hangup pogos.
Very useful to make outgoing calls from phones which had their dials locked/removed ... if a bit painful when the number one wished to call had an '9' or a '0' in it.
there were other variables to contend with on those old at&t phones everyone had, as the pegs you release to off-hook the phone moved faster than the switch under them. this means you had to tap fast enough for the CO to see them as dial pulses, but also slow enough that the peg and switch mechanism doesn't separate and cause inconsistently timed or missed pulses.
I think the biggest win would be getting rid of the big spacebar, and replacing it with more keys. (The thumb is much stronger than the pinkies; but we use the pinkies for all sorts of keys, and the thumb only for a few keys).
Although I think by the time a keyboard design gets rid of the big spacebar, it then goes on to make other improvements (like symmetry, being split) and so ends up as looking too unusual.
It's both weird and wonderful that they show two out of three pictures with the full-size ("printer style") USB B connector.
I guess old Arduinos had that, so they're trying to be part of the family, but it seems like a rather obnoxious choice for a board that small.
USB-C may have its own category of problems, but at least directional superposition isn’t one of them.
I have a weird obsession with number input devices for my DIY jukebox.
I could totally see using this to enter the 4 digits to pick a song.
I’ve long thought about touch tone phone keypads too. There’s a frankenstein jukebox at Zam Zam in San Francisco that uses one.
Get a good build quality and I bet you could sell them as desktop toys.
