I am looking for a tenting mechanism for ergonomic keyboards.
I would like to see a mechanism that is easy to use, inexpensive to manufacture in small series, strong, stable, silent and is compatible with gasket-mounting ... and doesn't feel cheap. (not just threaded rods and nuts)
Preferably, there should be detents or presets of some sort, if only to get left-hand and right hand-sides at the same angle.
Lets go deeper into the mechanism
If the threaded rod evokes a cheap feling we can step up to trapezoidal screws with anti backlash nuts
But if this is too cheap we can go ground ballscrews
What to do next to make them super simetric to each other well we can use absolute encoder and a servo motor per keypad .
Wel I know what you are thinking about f off stepper motors and their defined steps thats too cheap too well lets go with servo motors i guess ? To make them super simetric we could use a multi turn potentiometer per axis as an absolute encoder and feed it into a arduino
Yeah arduino i thaught so . Nope we plug them into a wheatstone bridge to measure the voltage digerence and use a complicated set of opamps to do a negative error amplifier .
So my final solution is a analog mechanical circuit with a precision upto 3 ųm with verry expensive ballscrews that copies the second keypad as good as analog electronics are able
Hydraulics come on ? You are bether of with steam
Just kiding guys you are the best
