SEE MY UPGRADED SLIDE SETUP which lightens the door and uses only wood, no linear bearings.

Here are the parts used. Hopefully the links will continue to work for a while:

The antenna: This isn’t the exact antenna I used because that one ended up having some issues that required the limit switches. Maybe this one will be better.

Light sensitive relay, designed to turn headlights on and off

Power supply: Wii supply 4amps 12volts, I think maybe down to two amps would work, like a cheap wall plug power supply you may already have.
