From the MIT website: “Fab Lab is an abbreviation for Fabrication Laboratory. It is a group of off-the-shelf, industrial-grade fabrication and electronics tools, wrapped in open source software and programs written by researchers at the Center for Bits and Atoms. Currently the labs include a laser cutter that makes 2D and 3D structures, a sign cutter that plots in copper to make antennas and flex circuits, a high-resolution milling machine that makes circuit boards and precision parts, and a suite of electronic components and programming tools for low-cost, high-speed microcontrollers.”
There are many Fab Labs around the world. In Amsterdam alone there are 3. I worked with the Fab Lab at Mediamatic to develop a procedure for making printed circuit boards, and led a workshop for 15 people, who had never used a Fab Lab before, to successfully build a Micro TV transmitter in just one day.
