Well you have my attention..although, I don't really have final call on approving these, the mods do.
It would be very cool to come up with a DIY device and perhaps we could sell the parts.
Can you provide more detail on 1) the total amount of the grant and 2) what you would purchase with the grant and 3) what the end product would be? a build of materials and an explanation on how to build the unit? (mp3Car could make a video here in house on how to do it by the way, if you created the documentation)
