Creating a Custom Logic Board for Savi's Workshop Lightsabers

In a previous video I covered how I broke the logic board in my Savi's Workshop lightsaber and my design for a very simple replacement board that would do just enough to turn the blade on. You can see that video here: https://www.youtube.com/watch?v=saLIxOtkLio In this video I cover assembling the PCB and resolving a couple design flaws and then installing my custom logic board into my Savi's Workshop lightsaber. It's a very long video. I've purposely included a lot of soldering to provide some (not great) examples on how to solder this sort of stuff. I recommend skipping around rather than sitting through the entire video. Different parts will be useful to different people. The schematic for the PCB can be viewed here: https://drive.google.com/file/d/16MOI-MjubDE7Z1HGYPHUIOkoWvbtR7KY/view?usp=sharing The code I had developed by the end of this video can be viewed here: https://drive.google.com/file/d/1hFHA4JxwLqT2aTmRPtmq3v-A_G-nJaNo/view?usp=sharing
