Soldered it up

Today my PCB arrived, and it was very exciting. It looks super cool, and feels high quality. It took me about an hour and a half to solder everything, which was WAY longer than I expected. It was confusing figuring out which direction each part went, because I wasn't sure what correspond to the square pin. Next time I'll label that more clearly.

I still haven't figured out how to power it, but thats what blueprint support is for! Sorry about the blurry photo

Changed shape

So it turns out that KiCAD uses radius for circles, not diameter- so my PCB was twice the size I though it would be. oops. Now it is under 100mm, and it is amazing how cheap it is to make

Changed the shape

I updated the shape of my PCB, and made it under 100 mm. I know that journaling isn't required for this project, but I couldn't figure out any other way to update the banner

Created the PCB

Since this tutorial doesn't require journaling, I didn't. This is the only way I know to change the banner though, so this is mainly just to update the banner per the instructions
