First, it's unfortunate that you ended up in a situation where you had to dry-lab the demo, but that does happen often enough. What's interesting is the fact that the audience didn't notice.
Perhaps they were all distracted by the power-outage. Perhaps, they really didn't have much knowledge or actual interest in what they were looking at. There's a pretty big lesson on demoing here. If such folks who are paid to write about it, maybe had invested in it, don't even notice a detail like the thing is still on when all the other power is out, then how much of our presentations will they notice?
On the other hand, maybe they were just really impressed that you had managed to design in a battery back-up by launch time.
This seems to be a very known story to me. So many times we had to get ready for a product demo. Believe it or not when "The moment" comes something or the other doesnt work. But yes good that LEDs were working for you. And believe me the VIPs and other big people are not always interested intechnical details.
Sheetal is certainly correct about the VIPs and others not being interested in "mere details", which often include product functioning and durability. Will the product outlive the 30 day warranty can wind up being quite a challenge sometimes.
What they're interested in is the free champagne, the free jumbo shrimp, and "Can I make a quick buck off this?" with no clue or interest in what the new product is supposed to do. This is the difference between engineers and idiots.
Well David, I didn't mean for it to sound quite so harsh as to divide into two groups. Granted there are many idiots in this world, but also many non-idiots are non-engineers. Let's just say I've experienced all four types.
Yep, and my tongue was firmly in my cheek - you just can't see it on my small photo.....
Lets just say that non-engineers, generally, seem to have a higher proportion of idiots. When you get into marketing and bean-counting the proportion seems to get pretty high.
And talking of dividing the world into types:
There are 10 kinds of people in the world - those who know binary and those who don't......
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.
