The team of people working on the Internet of Things Microscope have won a first round prize for their work!  They are now qualified for the final round that will be decided in October!

Here is a link to the project:


If you are interested in participating, we will be meeting Thursday nights now through the end of the competition.

The team met up again this week and is trying to nail down design ideas for a nice travel case. It seems tricky to balance lightweight and ease of use with beautiful design elements. One idea is to put the pi and hat in a box under the microscope. The box could also hold the LED in place but it also adds weight and when one of your ideas is to make it lightweight for carrying out in to the field adding weight is not ideal but putting everything together in a nice package is ideal. Come next Thursday to see what happens or to add your great ideas.

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!
