I wrote a nice story earlier about experiments with LEDs as ESD indicators, but it disappeared, so here's a short summary, then I'm done. The LED survived many HBM discharges at 27 kV, the highest I

Tried to confirm it worked fine, then the confirmation went to error and disappeared. Will try again.

I don't know if it's just me, but to me, the user interface sucks now. I just lost another long message I was trying to post - it just disappeared when I hit SEND. The navigation doesn't work right,

I use a regular hacksaw. If the cut turns out to be irregular, it is easy to straighten it with a file.

Here's how I manage it: /g/TekScopes/album?id=294969

A shopping cart that accumulates a static charge fits the Charged Device Model (CDM). It doesn't really matter which direction or polarity the charge represents from a perspective of being shocked.

Depends upon the manufacturer. I’ve seen both. Phenolic is also suitable since it is usually strengthened by application of a mesh to both sides of the material. Greg Wed, 08 May 2024 23:57:14

I would suspect their choice of floor wax and the material the cart's wheels are made from. The equipment is all grounded, so you have to generate the charge. There are floor waxes made to prevent

It would really help if people put an approximate location on ads. Though it seems no location means the seller must be American as they are the ones that don't bother saying where they live (and

If you're looking for direction, you'll need two of them I'd be tempted to use a resistor and neon with a one KV diode in series with the neon.? The neon will limit the maximum voltage to about 100

Could you use a small (NE-2) neon bulb for this? I recall holding the lead of one and shuffling across a carpet. I got the bulb to flash. Steve H. [email protected]> wrote:

Very nice. How do you get such a smooth cut of the can? George KD6NEW

Yes indeed, Steve gets the prize. That's what it would be called if such a thing existed. Ed

Sorry, what's SCM? <edbreya@...> wrote:

The LEDs would protect each other from reverse breakdown. They should be stout enough to take the forward hit and flash. If not, you can put some C across them or R in series to soften things up

Still looking.
