Would anybody know how i could make a keyboard that would work without a computer?
My idea would by a keyboard that you could type in, and the signals would be sent to some circuitry (would an arduino work?) and stored until you could send the files of everything typed up into a notepad file.
It would also have to be battery powered, and preferably not bigger then 2-3 times the size of a normal keyboard.
I am making the idea so that i could type stuff when at places other then home (and i dont feel like taking my laptop (mostly for stuff like on the subway, or when waiting... (i don't care that it will look absolutely ridiculous!)
Anyway, thanks for your help! Even if you don't know how to, but have any ideas, share them! everything is welcome! Thanks.
