This is Simple non-contact voltage tester using transistors next one circuit that use all transistor as main,it is cheap and easily build. Which many friends likeNon contact AC Detector Voltage. It use CD4060 as main
This non-contact ac voltage detector circuit, using digital IC CD4060 as main components and resistor and LED display only. it is use 9V battery as power supply.
If you are looking for AC power measurement. To use it just a little, which is not worth it. When we need to buy an expensive tool. Because use little…
We have many ways to indicates an AC line. A good way, the AC mains voltage indicator circuit with a LED. It may be the best choice. It saves and to be easy.
This is Simple monitor turn on delay circuit, by use contact of relay acts as a switch. When entering an AC main to this circuit. The circuit will delay while Reduce the surge current protection with fuse.
