Resend with properly formatted topic tag. :(

Hi all.

I need to to measure weight or to be more precise, measure if weight is
present or not in the rangeo of 0 to 100kgs.  I really need some sort of
flexible mat/pad that can be slipped under a cushion.

Does anything like this exist?

In view of the discussion on Sunday, have you considered a pressure switch that
gets put under a doormat for burglar alarm/shop alarm type purposes? As I
understand it you only need on/off and that would give it.

You can build one yourself if you like.  These are common for Halloween
effects.  Here's a link:  vol.com/~infidel/halloween/mat_switch.html
I don't know how long these would hold up, however.

Hi all,
       All most all riding lawn mowers have a "get off the seat kill the
engines switch.  Most of the work here is already done.

Hi Bill,

Your riding lawn mower has multiple engines? Wow, I'd love to see that in
action ;-) (Visions of something about the size of a dumptruck with arrays
of engines comes to mind)
