Welcome to the Island Underground. There may be other tech artisans on Whidbey Island, but I haven't found them yet. Until then, it's an underground movement.
I have always liked to make things. There is nothing better than an idea that begs its creation. My preferred mediums are software, electronics, and steel.
When working with Arduino boards, it doesn't take too long before you get tired of plugboards and "flying wires" and want something more professional. Pre-covid, I was putting together a class to teach complete noobs how to use Eagle to create their own low cost printed circuit boards (PCBs). The class project will be to create an Arduino shield that implements a toaster oven solder reflow controller. The resulting controller would be used to create all your future surface-mount circuit board projects. More info can be found here.
If there are more underground makers out there, drop me a line and tell me what you are doing. I could talk your ear off on things like:
PCB design and fabrication using Eagle
C++ for embedded systems
Design of switching power supplies for small computer projects
Analog modeling in Spice (not that I am an expert!)
...details on any of the projects on this site
As always, more to come!
