I was wondering if anyone knew where to get a tiny keyboard like a treo or blackberry would have. I'm looking for something with a simple pin interface, not USB or anything like that.

Maybe something like the Ericsson Chatboard:
http://cgi.ebay.com/OEM-SONY-ERICCSON-C ... dZViewItem

There is some information available for using this keyboard through serial access to the chatboard:
http://www.brolinembedded.se/projects/keyboard (halfway down the page).

Good luck and keep us updated please!

Edit: Just realized that the article talks about the CHA-01 and the ebay link is for a CHA-10, so I think some Googling for valuable info about the CHA-10 would be necessary

Edit2: halfway the page in this link you see the pinout config for the CHA-10 (drawn in ascii). http://mageforge.com/forum/viewtopic.ph ... b10aa07646
