Build Madison will host its annual event Nov. 19-20 at Sector67, organizers announced recently.

As previously reported, Build Madison is a free, 24-hour create-a-thon in which the community can create projects they’ve been thinking about. Projects have ranged from basic software and hardware to engineering.

Saturday begins at 11 a.m. with participants pitching their project ideas in 30 seconds to gain the interest of others who may want to help with the project. From there, participants are given 24 hours to develop their project. Each product is presented on Sunday.

Registration is open to the public and can be found online.
