I made, installed, removed and then repurposed two power conditioners. The more versatile of the two is now used to condition the 5v power that runs to the LIDAR sensor. The brown-out device is still available, and I may use it as a supplemental power input on the Garmin GPS-Comm or the Dynon. I appreciate the several rounds of consultation with Charlie England (AeroConnection guru, #2 to Nuckolls).
At the front of the plane I have gone through a heck of a lot of circuits, and decided to organize them onto 3 buses - a 20-fuse main, a switched 8-fuse for cabin accessories, and an always-on 6-fuse dedicated to the radio stack. At the rear of the plane I have a 6-fuse main and a 14-fuse engine bus. All in, that's 50+ circuits!
