What just went ka-bing on my stove? I was just cooking pancakes on the stove. The oven was also on at 300 degrees, to keep the pancakes warm as they came off the griddle. The overhead bonnet light was on as well. Suddenly there was a strange flash. It happened in such a fraction of a second that I cannot tell you where it was from. It was like a tiny red sparking mini-explosion -- somewhere! I turned off the stove -- and could NOT turn off the light on the bonnet! [more inside]

After a move, our computer (an older aOpen desktop) can't sleep through the night. It's fine if we leave it powered on, but if we put it to sleep, it seems to lose power sometime in the night and does not wake up properly in the morning. Will a cheap UPS (this one, for example) solve the problem? Any other ideas?
Four days ago there was a storm. Standing ankle deep in water which had flooded up to my front door step, I stuck my metal key into my apparently 100% metal door and ended up sort of electrocuting myself, feeling a tingle and shock going up my arm. Since then I've had this weird tingling sensation in my right hand and arm up to my elbow... just now I tried to hold up a can of soda my fingers and hand tremble. Now what? [more inside]

Our bathroom has a GFCI combo switch/socket where the switch is hooked up to the bathroom fan/light. It's wired downstream of another switch controlling the vanity fixture, and set up so that the socket is only hot when the switch is on. This makes it suboptimal for, say, charging an electric razor or toothbrush overnight, because that means leaving the fan on. What's the best way to change this? [more inside]
