John,

I obtained a copy of the Eagle CAD schematic and board layoutfor
the printed circuit board that was created early on for the first
version of the Minima.  I have rolled a number of recommended
changes into that schematic that is (maybe informally) dubbed
Minima v1.1.  I am not sure that you are interested in that or
in the changes related to Minima 2.0.  I just wanted to mention it
to you as a matter of full disclosure.  I'm maintaining it for
historical purposes (if nobody else is doing it) and because I'm
implementing a Minima v1.1 using that printed circuit board.

73,

Mac AE5PH

Where would one find the latest schematic. It seem that there has been a lot ideas and changes mention. Have any been incorporated into the original schematic? I think I have decided to build in stages, which would allow new ideas to be checked out.

mac,
there is no problem at all. all are free to experiment, design pcb and
measure. all i am trying to avoid is sale of pcbs at a commercial level
that will come back to bite us. people are free to etch their own pcbs, or
make minima ugly style. your website serves a very useful purpose in that
regard.
unfortunately, there is a tendency among the kitters to sell kits that wont
work and we (you and i and the rest of the minima group) will have to keep
explaining that this is an experimental rig that wont work as 'advertised'
by the kitter. hence, my reluctance at allowing commercialization.
have a great day,
