@kfield: Sounds like you could have used a forklift to carry away everything you saw that you wanted to buy!
My chum Rick Curl had a backpack, but he had to make multiple trips back to his car to stash everything he was buying. I did see one guy walking aroudn with a big suitcase on wheels -- that was a good idea :-)
Don't just support the hamfest. Get a ham radio license, too (if you don't already have one). Getting a Technician Class license--the license class for newcomers--is really pretty simple. And, you can download my study guide for free by going to http://www.kb6nu.com/tech-manual.
If you have any other questions, please feel free to contact me.
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.
