This is just too darned cute! I'm impressed with the hand-drawn schematics, which take me back to when I was about 10 or 11, and I decided to dissect my tape recorder to figure out how it worked. I ended up with a schematic showing the guts of the machine, which, thankfully, still worked after I put it back together. That further inspired me to build a Heathkit receiver that -- half a century later -- still sits in a box in my basement somewhere. There is no question in my mind that several of these kids will go on to tackle other projects in electrical engineering.
A lost art indeed. The hand-drawn schematics bring back memories. My wires weren't much straighter or any more parallel than these. Luckily, accuracy counted more than geometric perfection. Nice to see kids doing these projects.
I like how all the students featured here did something that represented their state or local area. It kind of reminds me of the state fair or county fairs and how as a kid you would enter something and get a ribbon. (Like entering your chicken or pig.) Does anyone know if the county fairs have an electronics section?
I once had an intership at the California State Fair media relations office. I can say for sure there was no electronics section then. Not sure about now, but I kind of doubt it. But I agree with your sentiment. The fact that they did something to represent their area is fair-esque.
I actually enjoyed every slide and video shown here! Each demo comes with an initial sensation and pride: "Look, what we've done!" I loved the Les Paul guitar thing (image 4). But of course now that I live in Wisconsin, obviously, Lambeau Field demo gets my vote.
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.
