BLDG 61 Event Calendar

BLDG 61, the Boulder Library Makerspace, is going to SPACE! We are taking applications from students (grades 9-12) eager to participate in this exciting citizen-science project which will launch electronic sensor kits to the edge of space.

Participants will be challenged to program, construct, launch and retrieve electronics that will collect weather data and images during a high-altitude balloon flight, miles above the Earth!

BLDG 61 woodshop sessions provide an excellent opportunity to learn a new tool, use equipment you don’t have access to at home, or get guidance on a woodworking project. Access to shop equipment is scheduled through our calendar and organized by the level of supervision a specific tool requires. Basic tools require the least staff guidance, while Supervised requires the most. See the table below for details.

If you are completely new to woodworking and unsure of the needs of your project, we recommend checking out the Shop 61 playlist on our YouTube Channel and signing up for a Supervised time slot on the calendar. During your first visit, you’ll work with makerspace staff to determine the needs of your project and which sessions would be correct to sign up for in the future.


Time slots for tools and processes that require little to no supervision while working primarily at the workbench in the shop.


Time slots for machines that users may need help setting up and then be run with little supervision.
