Here’s one of my favorite keyboards, which I made in July of 2021. This is the
Clock Keyboard.
The way it works is that it is a clock (not the analog one on screen, that’s just for show for the video), and it has one button. The button types the key that it’s currently time for.
And what key it’s time for is determined by the minutes of the current time:
At 0 minutes past the hour, it types an “a”.
1 minute later, a “b”.
and so on.
Typing “Hello World!” into twitter took 5 hours and 24 minutes.
