My wife "suggested" that I keep my vinyl collection and turntable in the closet adjacent to my computer desk. Actually, it works out well, since it has a baseboard heater, and the lack of a HVAC duct helps keep the dust down. I keep the door shut most of the time, but that means that I have to open the door if I want to control the amplifier volume with the remote.

ESP8266 to the rescue! A simple circuit with one transistor driven IR LED, and programs by B4R and B4J, problem solved.
