That is cool, I was going to do the same thing! Went to C.Tire and they were sold out! So you are the one who scooped me! I got a rain check for 10 although. Also if they are the ones I think, they have a small circuit built into them. But don't quote me on that. I will have to actually open one up to see. I will be interested in your outcome. I like to see others familiarize themselves with a method. It only helps others.Thanks, Joe
