I went to my first Maker Faire in 2014. It was the Cincinnati Maker Faire. It was a great time! I brought with me my Christmas Tree lights project. This was done using a Raspberry Pi and a lot of other electronic components. You can see how I built this along with a FREE downloadable build list!
For the kids to play with I also brought a Circuit Scribe. It has a pen that conducts current. The kids enjoyed drawing their own circuits and making the LED lights light up.
