Last night I designed a small host board for the PIC 16F688. When I have the money to spare I'll be sending it out for fabrication.
Hardware design is the one area of hacking I really want to work with. Probably because it involves more real engineering than programming does. My interest also has to do with the fact that software can never expand out of the bounds of the hardware it works with. Ergo, build more hardware.
PS: Yes, I do see that I put 18F688 in the IC socket. I just didn't feel like going back and correcting it.
