Peace of Mind Door

I'm sure most people, every now and then, get a nagging doubt in their mind: "Did I *really* remember to turn the oven off?"

Some people wonder just occasionally, some forgetful worrywarts suffer this anxiety much more often. Mostly, we usually decide we did turn it off, and we're usually right. But it's all so unnecessary - unnecessary worry, or unnecessary trips home to check, or unnecessary flaming infernos if we really didn't turn the oven off.

So, let's wire up a switch to the door. When we shut the door (or better, when we lock it, but that might be trickier to do), that trips the switch and, after a minute, the circuit turns off the power to the oven. Of course, we don't want the oven turning off when we're at home, or just because someone else has come in while we're cooking, so the one-minute delay gives you time to press a button by the oven to override the door, if you're actually cooking at the time. That same button lets you reset the circuit and restore power to the oven when you get home and want to cook.

Now, with this nifty device in place, you need no longer worry about remembering to remember whether or not you turned the oven off. If you didn't, your door did!

Also, with increasing awareness of the need to reduce energy use, you could set this up to turn off other household appliances too. You can cut power to the TV, you can turn off your heater, you can even trip the light - fantastic!
