Though it's outside the normally scheduled activity of, "Get together, drink beer, talk tech", there are at least 2 out of 3 involved in this event.
This Saturday, March 29th at the Cleveland Public Library downtown, the Cleveland Mini Maker Faire is a gathering of nerdy demos, workshops and presentations. Chris will be presenting about KiCad (the open source CAD program). There's also 3D printing demos, crafts and more. The event is very family friendly.
