Nice boards Eric, look very promising. The SMC part may put some
people off, but as SMC is here to stay we need to get used to it........

have you noticed how commercial soldering pencils have become so
tiny lately !. Seriously I think this "modular" digital approach is  
what a
lot of people have been thinking about for some time but you are in the
lead at the moment. Look at how well the Midibox project is doing.
