Geekspace Gwinnett Moves In
The region's latest makerspace, Geekspace Gwinnett now has a home and is building out. I went to one of their regular Tuesday Open House events last night. They're in the building out phase. So far they have Wifi and workbenches with a couple of older osciliscopes. In the back shop area are a couple of drill presses, an old Craftsman table saw in need of a tune-up, a small metal lathe, cutoff saw and scrollsaw. A milling machine is in the works as soon as moving equipment can be arranged. All in all, about a dozen people showed up and the space has great promise. So come out to one of their events and learn more.
I updated the site from Joomla 2.5.x to Joomla 3.2.x. In the process I put a new, responsive template. I hope it serves the community well. Any comments and feedback are welcome.
