How do I make an automatic dog door?

The wife is getting a job that will not allow her to let the chahuahua
out at noon. Is there a schematic that I can use to make an RF auto
open/close dog door?

Thank you,
Rick

I have a nice dog door for my small dog. It has flaps on both sides, which
appears to discourage nocturnal intruders, and a plastic safety cover just
in case you don't trust it. It installs through a typical exterior wall,
and took me about 2 hours to put in (a friend had a nice stucco saw).

It was a few years ago, but I believe this was the one:

Strange as it may seem, the power of mathematics rests on its evasion of all
unnecessary thought, and on its wonderful saving of mental operations.

Garage door opener on an ordinary mains voltage timer.

Or electric door lock on mains voltage timer.
