Some terrific responses...surprisingly, no one has mentioned education yet...
We have five classes signed up as judges already! I think our student judges may be more towards late middle-school / high-school aged.
I have used this quote for years to explain engineering to students, but I believe it is originally attributed to Arthur Wellington in his book, The Economic Theory of the Location of Railroads: "It would be well if engineering were less generally thought and even defined as the art of constructing. In a certain important sense it is rather the art of not constructing; or to define it rudely but not inaptly, it is the art of doing that well one dollar, which any bungler can do with two after a fashion."
While a lot of the other entries are funny and/or descriptive, so far the one above from SarahCurry is the only one that is both succinct and understandable for an 11 year old.
In a way, I'm slightly disappointed. Engineers are supposed to be good at reading and understanding specifications, especially a not too complicated one!! ;-)
To Quote Freeman Dyson:
"A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering."
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.
