Makerspaces are fueling a D.I.Y. revolution. A blackboard in the TechShop makerspace in Allen Park, Mich., is full of ideas members have for what they want to make. TechShop is a nationwide chain of shops equipped with laser cutters, plastics and electronics labs, machine shops, wood shops, metal working shops, textiles departments, welding stations and a waterjet cutter. Members have open access to design software and huge project areas with large work tables for completing projects and collaborating with others.
