Intro: AC Detector Circuit With Awesome Application

Hi. Today I am going to show you How To make AC detector.

Speaking about AC or alternating currents, it is far more dangerous than DC. It can easily kill you if the voltage is 220v or 110v city power.

Before touching any live wire always make sure no high voltage is available there.

So, how you can check it?

    Not only an AC detector, it will react to any interference. The counter is of no use as it's never reset, any MOS gate would give the same result. Decades ago, leaving opened a MOS input drove to its destruction, inputs weren't protected as they're today. You can't rely on this fixture to detect mains. Another point is that alternative current isn't more dangereous for the same voltage, a contrario, because you can feel it, which isn't the case of continuous current. Continuous current makes an electrolisys of blood and produces bubbles in the veins driving to an emboly.

    How about some explanation on how this works? What happens with the circuit before its active and then when it is activated.

    basicly it is a decade counter, everytime the chip sees a clock pulse the counter moves one up.

    since the clock is floating and connected to a length of wire, it reacts to garbage because and can start ossilating because of that.

    Tapping the antenna would also turn on the led as well.
