So it's been a long time since I updated this, but might as well. The project has finished the next main step. I have working electronics that I installed on a custom chassis in my machined saber. Although not done the next step in the process would be to make a custom pcb, I'm also looking into using a feather M0 adalogger, since it has a built in sd slot and could save some room in the hilt.
Here is a quick viedo I did, it's mostly aimed at those in the lightsaber comunity, but it shows the electronics in action.
