What a great offer. Sounds perfect - I'm designing an adapter to be able to use a membrane-keypad with the CameraAxe. It's not quite finished (gotta double check the wiring of the buttons), but does this look like something you could/would do? https://www.dropbox.com/s/7emyqj81ueweqn6/ca_keypad_connect.pdf
