Vintage TV Sleep Timer Project

Our friend Viktor has dusted off one of his old projects and shares the details with us. If you have been burning the candle at both ends you have no doubt fallen asleep on the couch with the TV on. When you wake up many hours later the first thing you do is turn off the TV which was working away with no one watching it.

This Vintage TV Sleep Timer Project allows for a sleep function to be enabled into your TV so that when you fall asleep the TV will turn off by itself. This project doesn’t have much value as a TV sleep timer these days since most TVs have this function built in but there are still many uses for this type of operation. It reminds me of the train speed control which is tied into a dead man switch, this allows the train to stop if a switch isn’t maintained in the depressed position. This could be caused by a train conductor falling asleep or dying.

It is interesting to see how the circuit works since there is no microcontroller in place.
