So I’m thinking I’ll hand wrap some electromagnets, telegraph style. I’ll try firing then off next to each other, bit I’m pretty sure that’s going to fail. By fail, it’ll probably end up being like hammers on said keyboard. Having the wrong combination will give a false up of some kind. Next will be trying a V pattern. The distance might help, but I’m not really sure. If nothing else, it’ll give me more room to put the electromagnets. Last works be separating then even more and having it straight up look like the hammers of a keyboard. The last one though is going to require that each piece is pretty expertly machined…
Oh, hello. This is why I blog. I’ve poetically mentioned this before, but I remember an awesome anecdote I learned somewhere. At some CS lab, I think it was MIT, they had a teddy bear. Before you asked the helper, you had to fully vocalize the problem to the bear, and must questions answered themselves. I could just make a single key typewriter. One stepper to turn the bottle. One stepper to advance the carriage, one solenoid to hammer the bottle. Have the solenoid pushing along a track to ink the stamper.
Or… right. Rotate, and advance carriage as before. Cylinder of ink with pressure maintained by a screw, solenoid valve to give a moment’s inking.
I think number two is better, but number three is a possibility. Number three is much more likely to be really pokey about the ink consistency, but number two will have problems on the stamping mechanism fouling, and the material of the stamp not being properly chosen.
