The any key

This is going to be an ultimate any key : one button HID keyboard which you can reprogram to be any key or combination of keys you wish.

I saw such a thing few months ago on Facebook. Some friend of mine posted a photo of the gizmo, he got it as a gift from someone I think. And of course I thought to myself, why not to make one, and how would I implement this. I want to make to many things you know...Here is rough video: here is more elaborate description: works! :D

Enjoy this project?

Yeah, I guess. This single button above had something like this. It could emit programmed combinations of keys instead of single key-presses. So for example if you wanted to have "µ" you would program left alt + m, for Polish "ó" you would program left alt + o and so on. I am talking about a prototype of course, because production is another story.

In terms of programming this is definitely doable. Every MCU vendor provides a hid example these days so I'd start there. But recently i became a big fan of zephyr rtos which also provides a hid sample so if you're into operating systems this is the good place to start as well. Sorry for replying after 3 years, but i missed your comment.
