As always, comments and questions are more than welcome.
Many Delays
I’ve been pretty busy for the last month. But things are starting to move forward again. I’m still working on the project page for the Source Selector Unit and something new as well.

It really is amazing how much I can accomplish when suddenly I can’t work on all the projects which have been keeping me busy for the last month. The SSU assembly is complete and I’ve done some testing.

We’ve all done it or at least thought about it. It’s so easy. It’s really no big deal. It feels good. No one will ever know. Well, I’m here to tell you that eventually, you’ll regret it.
