I have some concern that too much addition to the spec, will end up with a monstrosity that is a nightmare to build, and no more compatible with the core goal than anything else already available :( > > > . hw and sw knowledge > > > > Of course. > > > > . testing and evaluation, and equipment for that > > > > > I have an oscilliscope and some other random hardware for testing with.
