    Hmm, the post is an excellent job on the matrix keyboard projects. I am just thinking to myself if it is worth to get in the trouble to built all these switch and wirings when a PC keybord has more keys, is very reliable and cost nothing!

    Of course you cannot embed it in your own shell, but that is another story.

    Just my thoughts, over a very nice project.
