Awesome place. 3D printers, excellent well stocked DIY electronics lab, laser cutters, lots of CNC routers and power tools. It's a coop, run by the members.
If you've only just heard about ATX Hackerspace stop by around 8 PM on Tuesday evenings for the regular Open House! The 1st and 3rd Tuesday of the month is the regular Member Meeting at 7:30 PM.
