you're right as usual....I'm only halfway through mug #3 of the day.  Fresh pot is brewing and should be ready in a few minutes, after I have emptied the mug and my bladder.

@MeasurementBlues: The insulation on the ground wire of all four of my wrist straps failed, exposing the wire inside. On one of them, the insulation is turning into a kind of black goo. It got all over my hands.

Uggh -- remind me not to shake hands with you again.

Are you sure it's goo from the insulation that got all over your hands ... and not goo that was already on your hands being transferred to the insulation?

Max, I should have been more clear. The insulation on the ground wire of all four of my wrist straps failed, exposing the wire inside. On one of them, the insulation is turning into a kind of black goo. It got all over my hands. On the other three, it just loked like the insulation was stripped away, but I surely didn't do that.

I'll send a link when my article is posted.

@Max,

I just needed to use an ESD wrist strap to work on my wife's computer. The insulation in all four of them failed. I'll write up a piece about it (with photos) and post a link here.

@zeglen: A banana plug will fit directly into the outlet ground hole without needing an adapter.

Well, you have to "splay" the end out a bit, and even then it's not a perfect fit -- I think these adapters will do a better job (but they are WAY expensive for what they are)

A banana plug will fit directly into the outlet ground hole without needing an adapter.  It does help to remove the banana plug plastic insulator sheath, not needed in this application.

@David: ...The best solution would be to get a mains cable with a proper 3-pin plug,  cut the...

One possible problem with this approach is that if you cut the banana plug off the lead, you might lose the 1M Ohm resistor (these are sometimes mounted in the babana plug itself) -- that's another reason why Wnderer's solution is favorite.

NEXT UPCOMING BROADCAST

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
