I've seen this before, too. I like the "Arduino, just for blog cred" (LOL) and the "hire someone to open and close this switch really fast". I assume the bobber is to keep the pin floating.... :-)
Very funny - that could be the only schematic that everyone understands! I like the "moral rectifier," and take a look at that resistor divider! It looks just like the one from electronics school!
Very funny Holly! I think my favorite component is the "magic smoke". I've let the magic smoke out of components many many times. You can't put it back and it doesn't work without it.
