Build Madison will host its annual event Nov. 21-22 at Sector67, organizers announced recently.

As previously reported, Build Madison is a free, 24-hour create-a-thon in which the community can create real products they’ve always wanted to build.

Saturday begins with participants pitching their project ideas in less than a minute to gain the interest of others who may want to help with the project. From there, projects are granted a 24-hour development period. Each product is presented on Sunday.

Registration can be found online.
