I've followed a few of the folks for a while. Jeff Keyzer had designed an open source Geiger counter a while back. I took the design and converted it into surface mount parts, and then from an Atmel MCU to a PIC. He sold me the Geiger tubes.
He also published a very nice beginners guide to soldering: http://dfblink.info/jksoldercomic. It's popular enough to have been translated into 17 languages.
As I mentioned, from the mind of the engineer study, views do appear to be changing. Also for your reference here is the article you mentioned, aptly titled - Why engineers don't like Twitter: http://www.eetimes.com/electronics-blogs/pop-blog/4199325/Engineers-dont-like-Twitter
It seems like it was less than 2 years ago that EE Times ran a story asking the question "do engineers use social media?" and the majority of the commenters were fairly negative about social media in general and Twitter in particular.
I wonder if attitudes of engineers on this subject have changed since then?
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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
