We had a table at our Science Center's First Friday Harry Potter themed event.  We exceeded Di's personal fundraising goal by $500!!! The Griffindor scarf had 166 raffle tickets in the bucket. ($1 each/6 for $5/13 for $10) Not too shabby! The wands (craftfully made by several of our members) were a HUGE hit (and the primary fundraiser). Rock On!!! The 3d printed Golden Snitch got 150 tickets in the bucket too.

The Saint Louis Science Center opened a new Makerspace in June and has asked members of Arch Reactor members to contribute as periodic Maker In Residence.   Today Frank Kallel and Diane Sudduth showed off Laser Cutting!    We restricted ourselves to cardstock so that we could make a lot of things to give away.   We made Science Center Logos, "inspirationsl "makey words" (Create, Make, Innovate, Question, etc) and Frank made a wonderful SLSC bookmark.   It was a fun day showing folks how lasers work and showing a bit of the design process!

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!
