Interesting grounding story (pun intended)...I wonder whether they are any general rules for grounding noise sensitive systems? Every-time I discuss this issue everyone has a different opinion, looks like black magic to me! Kris
Twice, I've worked for startups that MBAs ruined. Company starts with handful of clever, hands-on workers with a great idea - company grows from 4 to over 100 employees in 3 years - fun, rewarding place to work for 2 more years - then the MBAs arrive - back to 6 employees and near bankruptcy 1 year later. I'm proud to say my company is engineer owned and operated ... and makes everything here in the USA! David, drop me a line at firstname.lastname@example.org
Thanks Bill. You sound like a man after my own heart. The place where I work at the moment, when I started, had one of the best comms networks I have ever seen, well thought out, well impemented and well maintained. Management appointed a bean counter to head us and since then nothing works as it should. Too many chiefs and not enough indians, and your quote fits sooo perfectly.
David, my quote was adapted from Ayn Rand in her book "Anthem", which is "What is my wisdom, if even the fools can dictate to me?" The "corporate constipation" is one of my own making. Having worked for a number of large corporations over my career makes me loathe the management structure at most companies ... I especially loathe MBA's, which in my mind stands for Mindless Bottom-line Analysts!
Love your quote Bill, I was going to put it as a signature on my work email but it's probably a bit toooo provocative.....
I googled it and it only came up with this post....do you know where it came from? (and if you're quoting yourself, I am still impressed!)
Reminds me of one of my favorite sayings: "What is my wisdom if I'm commanded by fools" and a term I use a lot when referring to large corporations: "Corporate constipation by policy". While I was still a technician, back in the early 60's, for General Electric X-Ray Division, I designed and built some clever and effective test equipment (I worked in the component test lab where we tortured resistors, capacitors, etc. until they failed). But since "technicians" couldn't be more clever than the engineers they worked for, my boss took all the credit. Today, I'm a successful analog design engineer (still no degree) with lots of products and several patents to my credit. These days, I do a lot of lecturing (including one at MIT) about system and circuit grounding and my specialty, balanced interfaces.

The concept of having somebody "vouch" for my engineering successes is something that I have often found offensive. After all, didn't they read my reports, which gave very detailed explanations of what the problem was actually found to be, and then a detailed explanation of the solution, followed by an explanation of the functioning of the solution. On the other side, it was often amusing to see that they had so little understanding of what was going on that they had to ask others about it.
Having someone to "vouch" for the solution was management's way of avoiding responsibility if any problems arose. The veteran engineer was showing either faith in the junior engineer's ability, his ability to comprehend the problem and solution, his leadership, or some combination of all of these. The junior engineer should have been recognized for his inquisitiveness and cost sensitive fix. The veteran should have been recognized for his skill and possibly mentoring the junior engineer.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
