I’ve never been much of a musical person. But my kid was playing with a toy piano the other day, pressing buttons and whatnot. I lay my fingers on the keyboard and thought “hmmm… kinda like the home row”.
So my question to the community: have any of you built musical keyboards? Did you post a blog or guide? At first I was thinking a choc switch with a custom long cap that was held off a pivot point at one end and attached to the switch at the other. But musical keyboards vary sound depending on how you press the note. So maybe Hall effect?
Anyway, keen to hear of any adventures down this road by others?
The most common way to sense velocity is to have two switches at different levels and calculate the delta to see how fast it moves between them. This does require precision, though.
