ajaykatal4026 It's a BC547. The circuit is called a Darlington configuration. One transistor amplifies the previous, so the gain gets higher with each transistor. 5 volts is connected to the collector of both transistors. The negative from the power source is connected to the cathode (-) of the LED. The anode (+) of the LED is connected to the emitter of transistor 2. The electromagnetic field produced by the oscillating AC voltage is picked up by the antenna connected to the base of transistor 1. This saturates the transistor and allows current to flow to the emitter. (base to collector ratio = current gain) The emitter is connected to the base of transistor 2 and the process is repeated for more gain (amplification.) When AC voltage is near enough, the transistors "switch on" to power the LED. This is also how an audio amplifier works, except an audio signal replaces the electromagnetic field from the AC voltage. ALWAYS insulate the antenna in case it comes into contact with the AC voltage.

[@Theghostescapes]

Acutally, if verifies that you have current flow without having to touch any wires.

[@JusticeAlways]

​@@Theghostescapes It detects if an oscillating voltage is present via sensing the EMF being emitted. It doesn't measure current flow.

[@jonclark4328]

If you're curious what's going on in the circuit, it looks like a darlington pair from BJTs and the coil drives the base current when a field is present. You should include a current limiting resistor for the LED and transistors because there is no "built in" resistance. Just a forward voltage for the LED and you're supplying that via the power bank but it will burnout eventually without limiting the amount of current through it.

[@j4ck3t]

I don't understand, the Power bank provides 5 volt, the coil provides next to nothing, it really cant be a lot. you have 5 volt LEDs, so it should never be a problem? they should last their expected life cycle.

[@jonclark4328]

@@j4ck3t The coil is providing the base current to a darlington pair of transistors. If you look up the current gain of a darlington pair, 10k to 50k, you'll understand why such a small amount of current in from the coil is capable of being used like a switch in this application. What dictates the current through the LED would have been a current limiting resistor in normal applications, but in this application, it's similar to hooking it up to a 5v supply with no current limiter. You may get by for a while, but it's a better design practice to make sure it'll work and include a current limiting resistor like half of the comment section recommends for good reason.

[@electronnuclear]

​@@j4ck3tthere is no need for it to be a 'coil' itself. in this video the coil just acts as one plate of a capacitor. (in reality there is no capacitor here, the conductor of the coil just acts as one) meaning you can just use aluminium foil and insulate it with tape. what happens here is when the coil is brought near AC, small current is produced in the coil as it acts as one plate of a capacitor (a capacitor will allow the passage of AC through it, since it has changing electric field). Although I won't recommend you to repeat, what you saw in the video as there is no detailed explanation.

Два транзистора спаивают так что один транзистор на центральном контакте имеет катушку индуктивности, она улавливает электромагнитное поле от проводов напряжения, а второй транзистор включает ток из контактов юсб модуля. Катушка индуктивности получает напряжение оно идëт по центральному контакту и включает проход току ток проходит на средний контакт второго транзистора и включает второй провод и получается что лампочка загорается а уровень тока регулируется транзисторами и лампочка горит сильнее чем ближе поднесëш катушку индуктивности к источнику электромагнитного поля.

I guess there are multiple reasons for that: (1) The detection inside a wall such as concrete isn't as easy to detect while drilling.

(2) On the contrary - even if the parts itself would be really cheap - having reliable electronic circuits built into a non electronic machine requires additional engineering such as housing design, additional cables and AC DC transforming - all additional costs.

Ngl I was curious what they planned on heating with this until I saw the ending 😂 🤦🏼‍♂️

[@robertbethune5418]

I love this video.

[@cd7071]

Or you could just spend a couple of bucks on a non-contact circuit tester🤪

[@eddybash1342]

FET effect !

[@user-nb4er3je9g]

not to sound redundant

[@Raj-Singh_TRACY-CA]

Is everyone gonna just not say anything about the awesome music & how it intensifies as he gets closer to completing the build... it reminds me of something just don't remember at the moment what it reminds me of🤔🤔🤷‍♂️ LoL

[@F8Tributo]

Great creativity, great electrical knowledge, bad economics, bad use of time.

Do you know the name of this music?

@@MineralWater0000 Thanks!

The led turns on because of the presence of the collapsing *electromagnetic field* from the AC drawn in By the coil. The transistor senses it and let’s current pass to the led. Coils can convert AC to a magnetic field and back into AC given their turn ratio. This is how transformers work. And why you need a full bridge reciter to convert it back to DC for use in a DC circuit. 🤦‍♂️

[@ferrumignis]

This detects the electric field from a conductor with an AC voltage on it. It does not detect magnetic fields.

[@ferrumignis]

@@Crux161 No, because a transformer is a current based device; leaving one end open allows no current to flow. Additionally this would require that a current be flowing in the mains cable, but a detector like this will work with no load connected. This is an electric field detector, the "coil" on this device is simply acting as one half of a capacitor, it doesn't need to be coil shaped at all. Usings a flat plate would actually make this more sensitive.

[@mrromantimothy]

It's called a proximity tester or tick meter, and one should never fully trust it, always treat wires like they are hot. Do it for your own safety and good.
