Thanks to everyone that helped finish up the move last Saturday.  We have pretty much everything moved out of the old space and only have some minor cleanup left.

Thanks to everyone that came out last Saturday to help get our shop equipment.  We were able to get the entire shop moved over and the existing space cleaned up.  Look for moving events in the near future to help get the rest of the areas moved out.  Until we are completely moved over make sure to keep an eye on our calendar events or mailing list to see where we will be gathering!

Thursday, Feb 25th, 2016

Join us at Saturday Feb 27th at 10am to start packing up our shop equipment at Jefferson Underground and moving it to our new space at 2215 Scott Ave.  We have received our occupancy permits and are ready to really get moving!  Arch Reactor will provide lunch to everyone that helps out!

About Our Hackerspace

Arch Reactor was founded in 2009 by a group of friends who liked technology, programming, making, and pizza. Now St. Louis' largest hackerspace, Arch Reactor's growing membership continues to bring new skills, projects, equipment, and people to one place.

For a deeper understanding of what we're about, you should check out our explanation of hackerspaces, perhaps read about one of our members' projects, or (best of all) come meet us in person at the next open event!
