Lets get back on topic.

Ya. Thats what I was gonna say. So, what do i do again?

Take off the spring AND the foam piece to reveal the bare sensor, put a penny on top of that, then close it back up. Don't tape the foam too tightly back on and let the spring apply most of the pressure.

I can't really tell by that picture. Did you do what it said?

No, I tried. I couldnt even get the top off.
