To enjoy a Maker Faire properly, you first have to have a basic understanding of what a Maker is. It's fairly easy and straight forward. A Maker is someone who makes something. The most quickly understood of these are weavers, blacksmith, glass blower. You can also include wood worker, or other crafts person. They create a product specifically by hand that we may need and would use. There were quite a few of those at this past Maker Faire in Atlanta.
Then there are those who make things who are just for fun. It's still a made item, it has it's uses, but it may not be something we need.
Maker Faires, though, started to showcase those things that an engineer or programmer may have made. They showcased the technology that someone at home could do, but wasn't aware of.
Then there's the science and robotics (and fun) that are an extension of it all.
There were a lot more crafters, makers, and cool stuff on display out at the Maker Faire. Most had activities that kids (and adults) could participate in to see what it would be like to make things. Clubs you can join too. More stuff & people than I could easily share here. If you get a chance, I highly recommend going next year and plan to take a good portion of your day to explore.
