When I moved from Zim to Australia, I didn't "throw away" much, but I did sell off a lot of stuff...amongst which was quite a few of those telephone switches, some old strowger uniselectors, a box of nixies, a box of valves (tubes), some old ferrite core memories....all stuff I'd love to have now, even if just to hang on the wall. Such is life....
Good catch on "breathes" (as opposed to my saying "breaths") -- I just fixed this in the article.
I love the old telephone switches -- I want to get more, but they are mega expensive. I think
I'm good for lights at the moment, but don't you dare throw anything else away :-)
Also, shouldn't it be "The Amber light breathes three times..." or do they spell "breathes" differently in the States too?
BTW, love those old switches and lights - I had some too until I moved to Aussie, had to be ruthless. I might be able to get some really big lights (like 1 inch diameter) though not faceted - since you're going to be in front of a huge audience, would those be useful? I've rescued a few from old substations switchboards.
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.
