I build arduino hack for an scientific calculator that could emulate and read key presses. Could talk over 433mhz wirelessly to what ever i wanted. Was even able squeeze it back in its original covers.

Not a easy feat i can tell you.

I used to just types notes in the draw section and read them from there.
