Blast from past: Automatic shutdown timer for TVs

Posted on Thursday, October 4th, 2012 in DIY by DP

Back in the 80s when very few TVs had remotes, let alone automatic shutdown timer, Victor decided to build exactly that for his grandfathers TV. After a set interval an LED turns on indicating that the timer has expired, if a button isn’t pressed within a few seconds the TV is turned off.

My grandfather was known to fall asleep about 5 minutes into watching any program on TV in the evening. Then, the TV would go on all night long. Those TVs in the eighties consumed a lot of power, so one day I decided to make a small device that would automatically switch off the TV when he falls asleep.
