I was recently involved with exhibiting at the Maker Faire here in Atlanta. I participated with a group of friends under the umbrella of Oscar Eastwood. We made and sold simple circuit kits that were custom designed laser-cut critters with a LED, coin cell battery, battery holder, and conductive thread. It was a great experience and we loved sharing our designs with all of the kids who came by our booth. We are already planning on participating in more local creative events.
