Way more simple than my approach. I am wiring in a rectifier and a DC regulator on my AC lighting circuit. Probably gonna have to cut away wire shielding to see where in the heck everything goes (better than running the bike all day to prob for voltage and draw up a schematic by hand).
Your xr build has been great. Stripping mine down to the bones this winter to do a very similar project. Personal preference I guess, but I really wish you stayed with the more instructional walk through and lose the music. The wiring was the one I needed the most help with, was really hoping. Great video and series nonetheless, really appreciate you sharing!
