Christmas Spirit -O-Meter (Bah humbug meter)
I'm a school teacher and every year we have a door decorating competition...and we always lose. Last year, I tried working on an interactive door display that shows the users holiday/Christmas spirit level, ranging from jolly to bah humbug. My idea was the user would put one or both hands on a metal plate(s) and lights would show up showing their level of holiday spirit. Essentially, it's a skin conductivity meter that uses a row of led lights indicating the amount of resistance/conductivity.
Does anyone have plans available or can direct me to a site where I can find them. Preferably nothing too elaborate where I can just use a breadboard and electronic parts from Radio Shack.
