Wish I could go. Alas, I am too far away. I have two comments.
Why wait until the kids are in High School? My dad got me my first VOM (Volt-Ohm-Milliampmeter - before digital) on my 11th birthday.
Somebody needs to develop a beginner's oscilliscope. That was when I really started learning electronics. I was able to borrow a Dumont 'scope and later I built a Heathkit dual channel 5MHz 'scope. There don't seem to be any entry level 'scopes except for the Rigol.
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.
