TMR12 - Precise 12 Hour Timer
If like me your favourite slave clock is an early National electric wall clock built to last a life time, you'll love it, but it's very noisy.
So if you want to sleep at night use this timer. What this product does is turn it off automatically for you after exactly 12 hours and then turns it back on again after another 12 hours exactly. This action is repeated until remove the power.
For example: you can set it to the 'start with power off' setting and start the timer at 9pm exactly. You will see the red LED flash and the clock will be off for 12 hours. At 9am exactly in the morning the clock will automatically start up. This process will repeat continually.
If you set to the 'start with power on' setting then the clock will run for 12 hours and turn off for the next 12 hours.
This does of course assume you have a 12 hour dial.
Just a small bit of detail; this timer runs approx 1 second slow per day. This I found was the best compromise because if you have an existing driver that is slightly slow you have a bit of leeway for the clock to step the last step (e.g. 9pm) before turning off
