I think it might be simpler. I just took a close look at the controller for my slim adesso and note it is very small and very basic. I then opened up the keypad and noted the similarity between it and a previous one I opened. This unit once the plastic backplate is remove is still pretty much self contained, and now very slim. Only about 1/4 of an inch. Then when I remove the keys and their clever mechanical switches what's left is less than 1/8" thick. Its not flexible but it will still work for me. Now the challenge is repackaging it into a waterproof unit with new rubber buttons. I think I understand how the keypress works. What's inside the key's is simple a very small silicon...thingy.. that looks alot like a micro baby bottle nipple cover. It's really what makes the keys rise after a press too. What I need to do is incorporate that into a lowprofile rubber button and then seal this unit. Maybe dipping it in that liquid plastic that is typically used for tool handles. Anybody have useful advice? Warnings? Help for the technically challenged? ;-) Cheers -=JT=- At 06:12 AM 10/2/2001 +0000, you wrote: The best thing is to find a suitable keypad first, and then interface it to a suitable microcontroller. Most of these keypads are designed with connections to the rows and columns brought out to a connector. If you aren't into programming the keypad software yourself, you should be able to find some suitable code on the web. It's quite trivial, anyway. You will also need an interface to the Libretto - the PS2 port would probably be best as it's quite easy to interface to a controller, and has a 5V supply on one of the pins. Software for doing this is floating around, also. I could probably dig out some routines suitable for the AVR or PIC for you, without too much trouble.
