I got a plastic mat with those grippy teeth things to protect the carpet underneath my office chair at a computer workstation.
However it seems to build up a big static discharge, if I wipe my feet across it (no shoes). When I touch something, *ZAP!*
Trouble is I also do a lot of PCB work at the same workstation so obviously I can't handle the chips and wearing a wrist strap would be too much hassle.
Is there some way I can ground the mat, or do I need to trash it and buy a special type?
My PC's chassis is grounded, so I ran a length of sturdy wire from the case screw terminal, and taped a big loop of the wire, bare, to the underside of the mat. But that didn't help; I'm guessing the mat would have to be conductive in order for the static discharge to be drained through the mat to the ground wire? Btw I verified that at least the wire and chassis were grounded too, but it doesn't do anything for the mat.
It was only 15 bux, but still, this sux. ;(
