Great story! The ease of today's worldwide connectivity is taken for granted by most who use these everyday services, the result of much intensive engineering effort by many.
But I still remember back in the 60's when my ham radio licence finally arrived in the mail, and my first Morse code CQ on 40 meters from my home-brewed transmitter raised a QSO from Michigan. That was a real thrill, a home-built radio apparatus that could send electromagnetic waves all over the world.
It is a cool story. I love reading about history. I asked the author Keith where he got this idea of writing about Marconi.
He wrote back to me:
A few years ago at NI Week one of the presenters told the Dr Crippen story. It fascinated the audience. I meant to write about it then but just got busy and forgot but always remembered the story.
Finally I had time and started researching it last week. Turns out there have been a few movies and documentaries about the Dr Crippen story and a book, Thunderstruck, written a few years ago. I read the book, and other articles and websites, and it occurred to me to check to see if it was same radio on Titanic. It was, so I tied it all together.
Good story. Compared with wireless charging, which is very short range (in spite of Nikola Tesla's multiple experiments attempting otherwise), RF comms provided a service that no wired telegraphy could.
I'll grant the lack of a physical connector, which can be delicate, would be an advantage of wireless charging. But as much as the amount of wasted energy by all those wired chargers left plugged in today is being hyped, imagine how much more energy these wireless charges will waste.
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.
