Lee,

 I was researching back through mail because a friend asked to see your FOB design. I forgot if I responded to your original email but if not I really like what you did. It may not be practical on a large scale build but it certainly is nice packaging.

Attached are examples of how to package the open board FOB. This shows using a DB25 wired to emulate a DMK/URI. The USB connections are wired directly to the board from a cut USB cable. The board is mounted on a sub board where all of the connections are made. The two wires to the CM108 in the second photo are fed under the row of pins from the right and tacked at the last pin on the left.

I encourage you to make this a DIY project but the FOB shown here is being made and is available for purchase. I hesitated to make this public as it is more a service than a business and I don't want the producer to become inundated!
