So, we don't mind a small home renovation project every now and then, and this is one we're seriously considering. Instructables has posted a step-by-step guide on installing sliding doors which are powered by an air compressor , and which look super cool. As you'll see in the video which is after the break, it's a pretty simple idea, which requires a pretty fair amount of work, but the results are very impressive. The sliding doors are controlled by a panel switch and have a key which can lock them open or shut, and the door also boasts a vent above it for air ventilation after operation. Yes, we actually want one of these.
