My idea of a prototype
Here's the prototype board I built( Collapse )
The one I built is on the left.
vakkotaur thinks it looks like a rat's nest. :-P The board on the right is a Luminary Micro evaluation board for their ARM Cortex-M3 microcontroller. When I'm done programming, it'll be able to talk to the Icom ID-800H radio, showing the radio's status and accepting control commands for it over Ethernet.
