Star Trek Door (Extended Version)

This is the longer version of my video that explains the features of the automatic sliding door I built in my house.

Visit my blog for a full build report and all the details: http://uiproductions.blogspot.com http://www.instructables.com/id/Air-Powered-Star-Trek-Style-Door/
