It’s 10:30 p.m. on a Monday, and SoMa’s TechShop is buzzing with activity. Sparks are flying, the band saw is kicking up dust, and nerdy hipsters are in the conference room plotting prototypes. The creative energy filling the raw industrial space is palpable, and the brainpower is suffocating. The vision of former MythBusters science adviser and serial entrepreneur Jim Newton, TechShop is a membership-based workshop and fabrication studio filled with the kind of equipment you haven’t seen since high school shop class—only much more sophisticated and high tech. An avid maker himself, Newton wanted to build a space for fellow do-it-yourself buffs.
