Promoting and encouraging technical, scientific and artistic skills through social collaboration, education and individual projects.


Ace Monster Toys (“AMT”) hackerspace is a 501(c)(3) non­profit member supported organization founded in 2011. We support traditional makers and craftspeople as well as hackers both digital and material. Our community brings together people of diverse skill levels by providing resources and culture to build networks; co-work; and engage in projects that benefit individuals and the community at large. The resources we develop include spaces and a wide variety of tools and supplies to support making and learning.


Supporting our mission is met with more than just space and tools. We hold the following values as integral to our success:

We are intentionally growing a welcoming community of diverse people with an economically accessible offering. We bring together makers, craftspeople, hobbyists, entrepreneurs, programmers, creators and hackers in Oakland, CA and the greater East Bay.
The spirit of curiosity is at the heart of hacking, our culture of camaraderie makes for a welcoming place for those who are willing to try something new or ask how things work
Sharing expertise, ideas and knowledge is what makes growth possible as a community, individuals and professionals
We promote an environment of cooperation where conducting ourselves with respect for each other and the space is expressed though active transparency and communication

Pierre Grandin

Pierre joined Ace shortly after relocating to the Bay Area. Initially interested in the Raspberry Pi meetup, the amazing culture of sharing knowledge quickly led him in learning about many of the tools that are available at Ace, from the big CNC router to 3D printing, and, of course, laser. After two years of membership, learning from others, he became more involved in running the space by helping wherever his skill set could be of use.
