I can't tell you how many Made by Monkeys and Sherlock Ohms postings have involved static electricity. A lot. Static electricity has been the culprit in tons of design stories. Do you have any of your own stories that involve static charges?
Dwight, you write very well – great article. Your descriptions of 'back then' vs today are hauntingly familiar to me as I was right there with you both times. The various companies I've served over the years learned the same lessons you've described, and ESD prevention has steadily gained prominence to become a standard initiative in the electronics industry. But because of that, I am very surprised the new camera you bought suffered a catastrophic failure from an ESD shock. It seemed to me that EVERYBODY was designing for prevention these days.
Remarkable, I would have thought that with modern products and the amount of ESD testing that is supposed to be done that this would be a thing of the past. I've been involved in product development for the last 30 years and we zap thing repeatedly (30 times in development and then in compliance testing another 30) with 8kV positive and negative to all metal accessible parts and we don't even see a reset let alone damage. I wonder what went wrong here?
Unfortunately adequate ESD protection does not add to the "features" of a product, and it's lack will not be obvious until after the product is purchased and used a bit. And the very short warranty period has expired. So a bargain thing will usually have inadequate protection.
Of course, the story sounds like a really large charge was delivered, probably far beyond the typical one that a minimal system would be protected against.
Before you completely give up on the camera, try something:
Remove the batteries for a week or two and then replace them. The microcontroller may have jumped to a nonvalid program location. It may be jumping around in the program. Once the internal capacitor discharges, it will reset. I have had that happen with cameras and other comsumer products.
Years ago I worked with a SW engineer who just couldn't (or wouldn't) take ESD seriously. One of his habits that drove me up the wall was he would put an IC on his plastic notebook and just slide the chip around in a circle on the notebook (a good way to zap the chip).
We could never get him to wear ESD straps. The final straw was when he walked into a lab I was working in. We had operational equipment set up on an ESD safe bench with the covers off. He walked over to one of my modules and touched an accessible board. I heard the zap from over 10' away. He destroyed the module. He also found new opportunities elsewhere not long after (probably unrelated to the ESD event).
It amazes me how so many people (many smart Engineers) just don't understand how little static electricity it takes to destroy electronics. Probably because often the induced failures are not catastrophic (the device will even appear to continue to work). Many of the real failures are manifest as weird or mysterious problems that cannot be pinned down. Because they don't see a ZAP and then a truly dead device, they assume they've done no real damage. I'll continue to be paranoid and minimize such problems.
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
