Misused the word sight. You didn't catch that I dropped the "r" in riduculous? You're a smart guy to point that out. Thanks for the lesson.

One might comment about your own illiteracy.  You might consider checking dictionary.com .  That site will permit you to cite a word correctly and not appear short-sighted.

The only thing more ridiculous than this story is the amount of technically illiterate people contibuting stories to this sight.

So, you are saying the power supply wasn't properly grounded and the output was float in reference to ground. Sounds like things were not properly installed and grounded. I don't go along with the Vandergraf garbage,

I agree, Rob. It's amazing that problems like this one ever get solved. This isn't just a glitch; it's a sub-system glitch, made even tougher to find because firmware was supposed to be the culprit.

You're lucky you were able to isolate it. I've seen many intermittent failures in the lab, which were impossible to reliability repeat, and thus diagnose. I suspect this is something that's very widespread, and accounts for a lot of in-the-field glitches.

Actually, the grounding precautions were not so much for the equipment, but for the safety of the developing prototypes and new product introductions.  But the equipment is normally sitting right on the same bench as the product, which is the target of the  precautionary measures. And yes, this was a recent practice used on manufacturing floors as late as last year when I was introducing a military computing device at a domestic OEM.

Wow, Jim. Is that type of restriction common these days? I would imagine there are ways to ground equipment that doesn't require personnel to wear such elaborate gear.

You're right, Beth. Time after time, the Sherlock postings show that the problem is simple beyond belief. It's amazing the problem gets solved at all.

Boy does this bring back memories of grad school. We had an ultrafast-spectroscopy instrument that we assembled from $1.2 Million of lasers and fancy electronics equipment. In essence, our system was a very, very fast strobe light that would illuminate a repetitive chemical reaction at precisely the right time. We used a liquid nitrogen-cooled scientific CCD camera that would record the faint output signal viewed through a maze of optics and filters. We would darken the lab and use upwards of 20-min CCD exposures to collect the very faint signal. Every now and again our data would be extremely noisy and we would have to collect data again. After some major sleuthing, we discovered that one of the PCs on the far side of the lab running Windows3.0 had a screen saver consisting of a bouncing ball. All but the top 5% of the computer monitor was obscured by equipment and only when the image of the ball bounced near the top of the screen did the extra photons get entrained into our optics. I've disliked screen savers ever since...

After more than a century of dedicated service, metals are still upping their game and delivering lighter, stronger bodies and frames to the auto industry.
Suppliers are chipping away at the dominance of the venerable polyvinyl chloride (PVC) electrical cable with rollouts of new environmentally safe, recyclable alternatives.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
The new entity, Celera Motion, will continue to sell Applimotion and MicroE kit-style product lines and leverage their combined integrated assembly expertise.
Practically all electronic devices today contain metals that may be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
