Made some good ground on the car PC this weekend; managed to get the Phidgets 8/8/8 board installed, and currently have the (inside) temperature probe and light sensor connected up. Also got an external USB plug installed on the passenger side, right above the cigarette lighter plug.
I also mounted the front bumper sonar sensor into a custom aluminum housing I made out of sheet metal and coated it with silicone to make it water resistant. The picture isn’t particularly impressive, but I think it’ll work out nicely once installed (next weekend?). The metal cross it’s mounted on will be folded and used to affix it to the lower front grille on the expedition.
