Thanks, but please keep watching. I think I have a long way to go yet, and I love getting all the help! 
I had a bit of background in wiring up electronic sensors and controllers, control panels, what did what, etc. Even learned how to release smoke! But, I knew nothing about the actual component level stuff or making PCBs until you guys got me interested here. I am still fascinated by all this and with today's modern design software, ease of ordering parts & PCBs, it really makes it all very possible even while not knowing a whole lot. That is with some good help of course.
It'll probably be a while before I get anything assembled, if ever. I need some more schooling in that department. And I still can't actually design anything without help from you and Stan. Plus you two have all the good ideas designed and built already.
Digikey parts are the only thing I have gotten with tariffs added. So far they haven't been a whole lot per part, just a few cents or so. But it could add up. If one can justify quantities you can make up for some of that added cost. As I am sure you know, Digikey has some pretty steep discounts when you get up to larger quantities.
I would use OSHPark if I ever come up with anything small enough. As a test with OSHPark, I just tried the PCB above, $35.00 for 3 PCBs. They really go up with larger sizes! The PCBs could be downsized somewhat, but not enough to make that big of a difference. I have tested with every PCB so far at OSHPark so far, and they were all pretty pricey.
I suppose learning about surface mount components should be coming up one of these days soon, Stan suggested that above, and I have been thinking about it. Then maybe I can really shrink things up some? I have only tried soldering one thing SMT, it wasn't pretty. Some practice in that department is on the learning schedule as well.
