l am a little disappointed as it didn't dive into how to make it work nonetheless.
E.g. I am guessing the power needed to use my old mechanical typewriter at 120 key presses per minute (so 2 per second) based on needed force and travelled key distance to be in the 0.1W range.
Not a lot, but probably enough to power an efficient microcontroller with a small LCD display.
I am convinced that with the right setup this could be actually working!
