Hi partsnerd ...
Fortunately for me supply of components is not a problem, However my many projects / ideas seem to get side tracked during development so I spend hours , re configuring , restarting, reprogramming , re building, stopping, de-soldering, upgrading SW, planning a new project, etc etc I don't have that 'Go with it' moment that commercial business must have. Some projects do get finished ( more or less) and cased up but I am still thinking about perhaps a version 10, But it keeps the little grey cells ticking over and is enjoyable, just one of the many benefits of retirement.
