That is an impressive collection. But the captions on those pictures kept mentioning the level of detail on the models. To be honest, I've seen much more impressive details at much smaller scales right on this forum.
I just had a similar issue at our house. Our dining room dimmer switch was somehow back feeding into our power feed to out furnace. I'm not joking, it took 4 service calls until we finally isolated and found the problem. New dimmer switch and the problem was gone . Find a good seasoned electrician. Good luck.
