Ack, looked back and saw I had pointed you to that a while ago. As they say, the mind is always the first to go (I think). Anyway, it would make a great addition to your presentation if you could get Weird Al to agree.
Well, since you brought up aluminum foil hats, I thought you might like to see Wierd Al's parody if you haven't already. You might ask him if it would be OK to use in your presentation as well. <https://www.youtube.com/watch?v=w-0TEJMJOhk> Hope you're not too paranoid.
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.
