I built this when I was starting in electronics and I didn't want to spend a lot of money on a power supply. So I turned an ATX from an old PC into a fixed voltage power supply. I used it for one year because I got a real lab power supply.
If your kitchen uses gas, this can be a very usefull for preventing gas leakage or worst, gas explotions. It has been turned on for almost two years and still going well.
This is a simple and cheap DIY EMF detector, with it, you can detect wether a wire or device is conected to mains or turned on. It is very usefull if you're into reparing stuff or electronics in general.
