You apparently don't realize that almost all recent AMSAT-NA designs are
already open sourced and are available on the internet (such as
SuitSat/ARISSAT) or through the AMSAT-NA Journal, the Proceedings and
other publications. You just need to do a little searching.
Legacy satellites, like AO-7, are a little tougher since the concept of
open sourcing and the internet wasn't around then.
Many, though for sure not all, of the University cubesat design details
are also available through their own web sites or through the
cubesat/small satellite workshops.
The information is there. You just need to spend some time searching or
asking for what information you need.
