A Mobile Makerspace

Bring the Geekbus to You

About Geekbus

The Geekbus is a mobile makerspace that travels to schools and other organizations to provide STEM educational experiences in their classrooms.

See Inside

Inside the Geekbus, you will find 3D printers, robotics, electronics, and maker materials for hands on exploring. Thanks to the generosity donor grants and public support, with our programs students will be given the opportunity to learn new skills by using tools and equipment that they may not have access to otherwise.

The Geekbus program is operated by SASTEMIC, a San Antonio nonprofit organization aimed at connecting education, business, industry and military to bolster the local STEM economy. Tesoro, Rackspace, the 80/20 Foundation, the Maker Education Initiative, and Cognizant are also strategic partners in support of the Geekbus.

Our Story


The goal of all Geekbus programs is to inspire and spark students’ interest in skills needed for the 21st Century. We teach students the value of “Design Thinking,” encouraging them to apply these concepts to solve problems that not only exist in the classroom, but in their daily lives as well. By utilizing Project Based Learning, we also provide students with real world scenarios for learning.

We offer 6 STEM programs, each with Intro and Advanced curricula, for students in Kindergarten through High School:

  • Robotics
  • 3D Printing
  • Renewable Energy
  • Video Game Design
  • Hardware Engineering
  • Computer Software Engineering
