I looked at the schematics for the PinHeck and it's very basic, actually. It's a good, solid design.
The only complex portion is the PIC chip, which is probably beyond your average hobbyist to program. Also he uses a lot of SMCs which is difficult for hobbyists as well.
It would seem there's a demand for an all-in-one board that someone with basic soldering skills could assemble and use.
