Ever have a hankering to make something — a website, a costume, a hybrid electronic device?

BuildMadison will be a 24-hour "community create-a-thon" designed to unleash the creative potential of participants.

From 11 a.m. Saturday until 11 a.m. Sunday, teams of participants will each come up with an idea and make something, said Chris Meyer, director of Sector67, the nonprofit group hosting the event. He said the focus is on new types of software, but the project is open to people who want to create any type of object or device.

"The point is to give people a motivation to take something they have been tinkering with and give them a catalyst to sit down with a team and do it," Meyer said. "I think a lot of people are going to be out here, exploring some things that they don't do day-to-day in their jobs, necessarily."

There will be computers, hand tools and even sewing machines available for participants to use, and members of the Capital Entrepreneurs group will be on hand to provide guidance. At least 50 people are expected to attend the event, which could become an annual or semi-annual gathering, Meyer said.
