Who hasn’t dreamed of have a Star Trek style automatic door in their home (complete with “wooshing” noise)? Now you can build your own with the help of this DIY project and some pneumatics. The pnematic system uses an air compressor, a piston, valves, hoses, infrared sensors, and an Arduino. The best part about the pneumatics is that the “woosh” noise comes built in – No special effects department needed! Check out more details about the door.
