Hi everyone, just to give you a little update. I finished wiring all the Menards building, plus some. I have a total of 19 buildings, 7 lighted autos, my tank farm wired up to one 12v power supply that really pots out 13 1/2v. Lol
I have used 4 buck converters 3 of them set at Menards 4.5v and one set at 10v for my other lights and stuff. I still have yard lights and street lights to wire in, but all in good time. The nice thing is they all come on with one flick of a switch and no extension cords. Here are a couple photos.
