Re: One shot timer
Being somewhat forgetful and easily distracted at times, I built a timer unit that turns everything off if you don't hit a reset button every 30mins.
There is a warning buzzer that sounds a few minutes before everything goes off.
It was a project in one of the Oz electronics mags many years ago.
Haven't installed it since we moved some 8 years ago though - I forgot which box I put it in and there's way too many boxes.
