DIY Anti Static Mat
Turns out that dissipative mats are non-conductive. I was going to delete my comment but couldn't find it until now.Glass is not a good choice because while it's usually non-conductive, it can be given a charge.I'm going to switch to using dissipative a mat(s). - ecode
how about glass as a ESD safe surface? i do have a wooden esd setup similar to yours but im looking for larger. Will glass work or does that still conduct heavily. - PeterR153
I am a PC Onsite Technician and even though they can't see me when I am working, Dell, HP and Lenovo expect me to use an Anti-Static Mat and Wrist Strap when I am servicing computers. If something would happen and I wasn't using one, I could be liable for any unsuccessful repairs. I purchased one at Radio Shack for about $30 with the wrist strap, but you can find them for about half of that nowadays, and I don't consider that too much to spend to have peace of mind knowing that your equipment is safe. This seems like a good project, but quite a bit of work.
I suppose if you want to go the ultimate poor mans way, even if your not poor but just frugal, go barefoot. You know your grounded better than your panel when standing on concrete in bare feet and touch the metal casing of an aging electrical device with your elbow and feel that slight bite.
Put on cotton socks if you want some resistance. Not wool or nylon
Get a humidifier, it's an anti static mat for everything, lol. That's all I use. Great project though, and your conductive layer should be on the bottom not the top. It's job is to provide ground potential base for your insulating layer, which is not a perfect insulator as nitrile rubber is 625M ohms per 1/4" length (better conductor than wood). you don't want a highly conductive top layer to short out your work on. And an esd mat does nothing if you don't ground yourself first, or just get a Humidifier if it's at home or a small lab. Cheers
