This weekend is the Coney Island Maker Faire, where tinkerers, builders, and other shades of 'do-it-yourself'er will gather to show off their latest projects. We'll speak with Becky Button, a musician and avant-garde engineer, who's leading a workshop at the Faire for a homebrew instrument effects pedal she designed. Plus, two members of Hack Manhattan, one of the city’s member-run year-round maker spaces, Michelle Gengaro-Kokmen, and Robin Wienands, talk about the group's educational programs, open houses and monthly do-it-yourself repair sessions.
