I am currently using the Iduino for the
MPGuino, (I use a telephone cord ($1.99) with a wall mount jack ($0.99) mounted to the car for the quick disconnect.) I would like to re-build my
MPGuino in the manner of DCB's prototype board (For neatness) and be able to use the iduino to program the chip if I ever need to.
DCB: Do you have some detailed photos of both sides of your single board prototype? And, couldn't you change the pin settings to make the chip / LCD connection easier? (Yes, I know that this will make it not compatible with the currently constructed 'Guinos and could cause a branch in the software or can possibly be handled with a #define switch)
