About Arch Reactor[edit]

Are you a self-described ‘techie’ that is looking for your niche? Arch Reactor, St. Louis’ only Hackerspace is a co-op workshop and club for techies, tinkers and free thinkers. Part arts and technology clubhouse, part training ground for new skills and knowledge, Arch Reactor is a place for St. Louis residents to share and receive educational information and training on various topics and skills with access to the tools you otherwise couldn't afford on your own. We offer a work space for all kinds of artistic and technologic pursuits.

Arch Reactor started as a wish in June of 2009 with a bunch of people meeting at a pizza place to work out how we could make this great idea happen in St. Louis. Fast forward to December 2009 and we have a good sized room in a 130+ year old Lemp Brewery building! Growing fast, we've now moved to an even larger space in the Jefferson Underground building.


We are holding a business meeting every first Tuesday of the month. The following Tuesdays will be taken up with shop safety, building our space, hacking our arcade games, and socializing. All meetings are open to the public and we'd like to see you there.
