Most of us spend far too much time in front of the TV. So I designed a system that will automatically limit when and how much the TV can be on.
The system works by controlling the input signal going to the TV. This is done by adding a relay switch to the input cable. When certain conditions are met, the relay is turned on and the TV is able to receive the input signal.
