This is an excellent and simple voltage detector. Can a circuit like this be used as an antenna amplifier to improve reception on one's home TV set?
When the big press switch lights up, that’s usually a good indicator that there’s electricity running through it🤷🏼♂️
Lmao
Not all power strips have a light in the switch. But a no touch voltage tester is probably less expensive than the materials required for this.
@@harryrammer Or if you plug a lamp or a radio in and it lights up, it means there's juice.
Amazing way for soldering with cardboard. Will use this with my future projects. Good craftsment
Buy some perfboard. It costs almost nothing and I will keep your circuits together better. Cardboard is good though for testing circuits.
Nice for those who want to dabble in assembling one, but literally under $10 on Ebay and at Home Depot !
You learned what by buying one? Plus the cost is considerably less to build one, and you learned something. Why are people "especially in the USA" so against learning or educating oneself?
Oh you can buy a made in China piece of plastic with the cheapest quality components for a few dollars, then throw it in the garbage in 4 months.
You can buy matches or a lighter to start a fire, but knowing how to start a fire without either will serve you better long term.
To do it yourself is more fun than simply buy, buy, buy.
This one is less than a dollar, not including the battery.
Its very cool to make these yourself. Makes for a nice home project. I would suggest putting a small resistor in the circuit next time but it looks really good!
LED には 電流制限抵抗は必要ですよね。ところでこれはいったい何の役に立つのでしょうか？

A resistor for What? If you dont understand electronics just stay quite
@@denniss9620 It is very clear you do not understand electronics. Despite that you write insulting messages to others who do. You are the epitome of the modern age, arrogant in your ignorance. The resistor is needed because otherwise small electric charges in the air from static for example will set it off. The resistor would mean that it only activates with a consistent electric source rather than an intermittent small source. You are a fool, I would hope you could learn from this and keep your ignorant mouth shut in the future, but I sincerely doubt you will have that much intelligence.
@@paulosullivan3472 Give it up Paul this circuit is not going to detect non contact DC. Not to mention the power strip switch is apparently working backwards. I doubt that. And if you are worried about sensitivity you need resistors at all three collectors. I dont know what you mean by "small""resistor but one megohm would be a good start for the first NPN after the antenna. Now how does the antenna detect non contact open circuit DC voltage?. Also I think you would find this circuit is more sensitive to capacitance then static.
У меня на поливике и одной 1,5в батарейке собрано лет 40 назад до сих пор работает собирал для поиска сгоревших ламп в гирлянде проводку тоже находит
можно самому такое собрать, и проверить
Thank you sir, i'm pretty sure this circuit can detect break point in extension cord.
I am pretty sure it can detect nothing
No transistor is biased and therefore none of them will ever turn on. Transitor does not amplify without being turned on.
Well I've built it and it works...🤔
@@WizardNumberNext Haha... I love it... I was kinda thinking the same thing but!!.....Could'nt the signal from the AC or noise from the poor filtering of the charger "potentially" be picked up by his antenna? Thats connected to the base of the first transistor..... very high amplification.......and the signal would be referenced to the same ground. It just might be able to grab enough current to bias that first transistor.....soooo, I mean, it is a stretch with that poor excuse for an antenna and the slight fields involved but.... maybe??? I might actually have to build this damn thing!
Electroboom gives his thanks
I'm so confused by the extension switch, why is it working in reverse :O The device is cool though. Elegantly simple and super handy when you'd need to find cables in the walls.
Exactly what I thought. The switch when in OFF (0) position appears to be on, and in ON (1) position, is off!
@@ukeleleEric I know why. Because the part of the switch sticking up shows you the state of the switch. Notice how the switch also lights up when O is pressed down. That's terrible unintuitive design.
USA switches work opposite to UK and most of the rest of the world.
@@Roanokee but why does UK do it like that? In my mind, it’s like binary. 0 means off and 1 means on, and O is open so I is closed. Is there another thought process that makes the UK method make sense?
@@sploders1019 it works for the UK and possibly 90% of the world outside the USA. It doesn't really matter though. When I visird the USA I got used to it within a day or so.
You should have a resistor in that emitter follower chain somewhere, to keep a transistor with high leakage current from making the whole gadget saturate all the time. Like a 1m - 10m resistor on the first base to emitter.
"1m - 10m resistor on the first base to emitter"
Umm did you mean the first emitter to base?
Also I assume you meant 1M - 10M?
First emitter to base or base to emitter, same thing. Yes, 1M-10M
@@marcinmerrimack1726 Cool, tks
I was looking at the direction of "signal pick up" from the wire loop -> first transistor -> 2nd transistor etc. Time was when I'd have known & understood exactly what you were talking about and why but I've forgotten just about everything I used to know about electronics 😞
It's a triple Darlington connection. There's a high DC gain, but It isn't working with a DC current. The gain is necessary in order to pick up the signal from the antenna and amplify it enough to get current from the collector through to the final emitter stage. Forward voltage drop of white LED is usually around 3V. So the circuit doesn't need a resistor, unless you're using it to detect the output of a Tesla coil, or some other high alternating voltage source. If anything, it might need a resistor in series with the LED when using a higher voltage battery.
Amazing bro..................................
It's an amplifier. It picks up mains hum and produces enough current to switch the led on. Such an effect is usually just a nuisance.

Neat project. Why does your power strip turn on when switched to “0” & off when switched to “I”?
It's a Russian joke 😂. Yes, the marking is wrong,
LOL. That makes sense then.
"I" - on, "0" - off. It was valid even in the Soviet time.
BTW, it's not I and O it's 1 and 0. Just like a computer. Ones and zeros.
@@epicasphalt6298 even having this meaning it was never marked as "1". I have never seen this in any country.
But the idea to use I and O as the symbols of 1 and 0 invented in 1973.
Who thought it was a homemade TV Antenna?
First time I see a three-stage Darlington ...
And, by the way, first time I see such a weird on-off power switch ..... 😄
Good eyes, catching that backwards power switch! I missed that.
@Ennio Ricciardi To achieve current amplification to all 3 emitter-follower stages, all 3 transistors must operate in the constant-current (linear) mode of operation. One must bias or "force" the base of input stage transistor to at least 2.1Volts. Normally, one can implement a voltage-divider at the base of the input stage transistor . However I don't see it here and the circuit still works -- I guess I must have missed something, can anyone help me out? The current driving the LED at the output is Iout = Betaf^3 * Iin -- no wonder the circuit can be sensitive enough to detect the input signal!
The sensor head is basically an antenna. Incoming electromagnetic wave from the source excites electrons in the wire of the sensor head, generating an AC current at the input of the circuit (current amplifier). The circuit amplifies the current and use it to light up the LED.
Thank goodness I wasn't the only one to notice this and surprised on how far down the comments I had to go to find one...
What you have done here is create a super-darlington triplet of transistors, and the result is a massive amount of amplification, so the tiniest amount of current residuals making it into the base of the first transistor is enough to appreciably light up the LED. The required current into the first base to turn on the LED is so little that mere capacitive displacement current from nearby events crosstalking across a picofarad or so of capacitance is enough. NPN transistors such as this will typically have gains of perhaps 200 or 300 or so, which means the combined gain would be 10 million or more. If it was any more, like with 4 stages or more, I suppose mere thermionic noise would likely be enough and the LED would be lit all the time even if it was shielded from varying EM fields.
I mean OMG MAGIC THIS IS AMAZING HOW DOES IT DO THAT!?
You need to first figure out what Zin is for a Darlington. That'll give you a hint what's going on at the circuit's "front end."
@@demef758 You don't need any figuring out, just basic transistor knowledge is enough to predict what would happen.
I don’t know how I’ve lived this long without one of those. I have to go out and build one straight away.
Or you can buy one for as little as $5.00.
FYI - It will probably cost $2-4 for the components to build the DIY device.
The sarcasm is strong in this one ;)

@fred McMurray every tester i've seen has a light on it. i don't think i've seen a tester with a numeric display that isn't also a multi-meter. what would the units be? electric or magnetic field strength?
@fred McMurray again, every non-contact voltage tester i've seen has an LED indicator. you'd have to be going out of your way to find one that doesn't have an LED.
DIY projects are usually not designed nor tested to any set of standards/regulations that would guarantee reliable operation, hence why i make the suggestion that a COTS tester will be better. this is especially important for applications like this where you're trusting your safety to the proper functioning and calibration of the testing equipment.

Hands up who would risk their life trusting this..?
I've been watching your videos for awhile now, and one of the most intriguing features of your work is how it reminds me that technology is ALSO art: you make sculpture as well as tools and devices. Your "free-form" construction method also makes your process (no pun intended) transparent- I get what your doing and how you're doing it. Well done.
No. Technology is not art. And learn English grammar.
@@morpheus6749 Well, you're just wrong. Technology is the highest expression of human art. All else is a moribund world of the merely "decorative." As to grammer, if you can diagram the sentence properly, I might make corrections. For now, I assume your screen name is the popular reference ("The Matrix"). If it's the Greek god, just go back to sleep.
@Christopher Gurin It's clear that you have no training in engineering or science, and as such no understanding of what fundamentally differentiates technology from humanities. Science and engineering are purely objective disciplines in which there are precious few correct answers and a virtual infinity of wrong answers. Scientific truths are objective because they are in no way, shape or form dependent on human values or judgement.
If a product of engineering endeavor succeeds it is _only_ because it is built on scientific truths and in no way because someone finds it visually appealing. There would be a million ways to construct objects visually identical to said product, all of which would fail to perform the function performed by said product because each one fails in a subtle but crucial way to adhere to the scientific principles that made the product possible.
Art, on the other hand, is solely and entirely subjective, specifically subject to human perception. As such, there are no such things as objective truths in art, nor such things as wrong answers. What you may regard as beautiful I may call garbage and, comically, neither of us would be wrong.
@@morpheus6749 well, you’re wrong on many points: I’ll stack my credentials against yours any day, but the point is creativity is not restricted to the traditional humanities. I find it a peculiar conceit of the “ARTS” to assume there to be a lower creative standard applied to, say, design of an airplane, software, or any other technological product simply because they rely upon universal constants and the defined boundaries of our current scientific understanding. There is an assumption that art is all subjective interpretation, devoid of a disciplined approach to concepts of composition, line or form. Most of the artists I’ve been privileged to work with have a deep understanding of how to use those rules to attain the desired human response. Just because the language of art doesn’t resolve to a decimal place doesn’t make it less rigorous. Likewise, my own experience in software and hardware design has often benefited from a more intuitive, imaginative, approach. You can have the last word on this topic. I’m done. Try not to be so insulting in the future-you’ll have more fun (unless this IS how you have fun.)
A super darlington.
Well, ok. Try, a field effect transistor. FET, there are, a variety to choose from. I believe you will only need 1 component, for the same result. Oh, and if you want to 'see', even weaker electrical fields, like from the human body, try an Operational Amp Chip, like the 741.
the setup from video gives you an amplification of some 100x100x100 = 1 000 000, or more, at this level it will pick up radio signals and changes in the cpacity;
would be nicer if hooked up a speaker in there, then could hear something if the frequency would be 20Hz~16kHz
.
There's one of these lurking in my kettle...
Someone didn't know about it, and was very surprised and happy! Someone knew and remembered, got nostalgia. But for everyone this video was a nice pleasure!

I did not test yet but I think it was better you use MOSFET transistor in the first stage that triggered with voltage instead of current
I disagree, I find it hard to believe that you'll reach the required minimum gate voltage, where the bjt being current based should work just fine from such a small current source. Maybe you're thinking of jfets? Those should work just fine.
@@lazyh-online4839 thanks for your comment but it can be compensated by adding some offset voltage with a simple voltage divider ....
in this clip, you have a BJT transistor that has an open circuit in the base pin. theoretically, no electrical current can be generated to turn on the BJT transistor it seems this circuit works due to the result of a malfunction in BJT transistor.
In this app, you will most certainly pop the MOSFET's G-S oxide. Exposing a MOSFET's gate voltage to static electricity hits will blow out the FET with the first hit. Static electricity destroys MOSFETs.
JFET not a MOSFET as MOSFET is static sensitive and would be destroyed with just carpet walking static discharge. In the current design with zero negative feedback it is likely the base emitter junction will be damaged and eventually destroyed if the second transistor in the darlington pair saturates and practically applies 3V with no current limiting resistor direct across the base emitter junction of the final switching transistor.

Probably not what he had in mind but even as a kid I liked to think outside the box. It was pretty simple. I took one look at the telegraph key and pictured the car starting when I pressed it. I used the on/off switch, the alligator clip wires and the telegraph key. Worked great. Taught myself how to drive as my dad was always away working on a remote mine site.

BJT have Collector Cut-Off Current (actually less, than 1 mkA). And electromagnetic fields can give additional current into Base. Three BJT Darlington cascade give more than 1000000 times rate of Base Current of first BJT.
@@WizardNumberNext Yep, as fake as radio waves and transformers. Maybe you should spend a whole dollar on a few cheap NPN transistors and LED and try it before crying fake. The only "fakeness" here is your implied knowledge on how the circuit operates. Yes a MOSFET will work too, but your knowledge of bipolar junction transistors isn't as good as you think it is. The fact that he used discrete NPN transistors in a darlington configuration clearly demonstrates his knowledge is superior to yours. Here are some words you should ponder before shooting your mouth off: Better to remain silent and be thought a fool than to speak and to remove all doubt.
- ABRAHAM LINCOLN. At least he took the time and effort to create an instructional video and share it, what instructional video have you posted that is even as good or better? None - period.
@@clawsofscorpius the fact you ignored that none of transitor are biased, not to mention first one, shows how ignorant you are and your lack of understanding.
I am well aware of Darlington.
I do not do such videos, as I am rather busy with spreading my knowledge in material and WORKING form, WORLDWIDE. I am selling enterprise grade computer parts. I have sold over 4000 orders.
By the way
I doubt you understand assembly (x86, x86_64, PowerPC, arm, arm64), physics and electronics (there is no full understanding of electronics, if cannot workout exactly what is happening physically inside circuit).
In this circuit there is lely no way to turn on first transistor unless it would be brought close to huge transformer, which will brake in it fraction of second (to high current)
@@WizardNumberNext It's not my fault you're too stupid to understand the first stage uses an antenna to provide a input signal to the base, nor that you fail to understand how transistor gain is achieved in BJTs. You might want to inform the other people indicating they built a working version of this circuit that they're all wrong and it doesn't work.
Your command of the English language is pretty awful. If I understand what you are attempting to convey, it would seem to indicate selling "enterprise grade computer parts" in quantity makes you an electronics guru or engineer. If that logic works, attempt trading in your frequent flyer miles and upgrade to pilot the next time you travel. If you tried spreading your knowledge, it wouldn't cover a piece of toast let alone the world. Do us all a favor stay busy with your "orders" and refrain from posting uninformed comments.

Jameco (and other companies) sell non-contact voltage sensor kits that are nearly the same circuit as the video demonstrated. Maybe you should buy one and improve your knowledge rather than advertise your ignorance. You can read more about the circuit or purchase a kit from here -> www.jameco.com/Jameco/workshop/JamecoFavorites/non-contact-AC-voltage-detector.html Even a simple Google search for something like "non-contact voltage sensor schematic" is going to yield similar results to the circuit demonstrated. Since he didn't use any current limiting resistors the voltage needed to be lowered to prevent burning up the components used in his version of the circuit.
If you really want to be taken seriously and perceived as professional by other people improve your English skills. You should have used "break" instead of "brake", and "too" instead of the last "to" in the closing sentence. I taught college-level electronics, automation, and industrial electricity for 20 years prior to retiring from teaching. I know, whereas you think you know. I will waste no more time on you. We have a saying in the educational field - "you can't fix stupid". At the least try to address your deficiencies rather than flaunt them.
Thanks for posting this interesting film Mextraf, I love your background sound along with the re-use and repurposing of things and what a useful gadget to make thanks.
I keep a mass-produced version of this in my toolbox to check for power on electrical outlets. An electrician once told me they call them "chicken sticks." LOL
I assume that guy was not an *old* electrician.
and yours probably has insulation so it doesent explode in your hand when you touch a wire

Use a mosfet istead a bipolar transistor and you ge t a better sensibility!!!!
nice avatar : the most complete formula of mathematics
sensitivity
You get less gain.
Lots of reasons to NOT use a MOSFET here, but the best being "exposing the very sensitive gate to static electricity hits will surely destroy the FET."
No way.

Бля, премитивная беспроводная зарядка...
Yeah right what he said
I've been in electronics for 65 years and I'm guessing you soldered point to point with the paper attached and then removed the paper? Friggin' brilliant -- never have I seen that done.
good point!!!
That could make for some cheap little kits.
@@chaos.corner Or I guess what you could do is simply print the silk screen layer on some paper and make sure it's registered at .100 then attach to some readily made perfboard. -- I'm guessing it's been done. You could also print the connecting lines on the bottom with the solder mask layer (!)
This is knowing as Darlington configuration. It makes a huge amplification, that why it is so sensitive.
Very good job!
Excelente video , sin bla bla, al grano y súper útil.
disculpa, eso es un probador de corriente?
@@betcald-teach es un pequeño aparato que te ayuda a encontrar precisamente en donde esta el cable cortado.
Me imagino que si tienes un cable de sonido o una extension y no funciona, le pones algo de voltage y con ese aparato lo pasas a lo largo del cable y con la luz encendida te muestra que detecta que adentro del cable pasa corriente y asi hasta que llegues a una parte del cable donde la luz deja de prender indicandote que ahi es donde el cable esta cortado.. yo soy dj y tengo un aparato para checar los cables si envian señal o no.. pero con este invento podria agarrar esos cables que no funcionan y ver exactamente de donde esta cordato el cable por dentro y abrirlo para repararlo..
Show de bola. Qual é o princípio físico:? Os 3 transístores são para uma grande ampliação de um mínimo de energia captado pela "antena'?

Man.... your switch is mounted upside down, | should be "on" and O should be "off".
Your grasp of the meaningless is amazing.
@@dhanke2777 - great reply. The best I've seen in awhile.
Good eye.
That irritated me as well.
You realize that's not a 1 or a 0 right? 0 represents a closed circuit. 1 represents an open circuit....
очень понятно и доступно показано, буду свою схема собирать - спасибо за видео автор.
I discovered this on accident taking apart a solar light in my house. It was dead..but once apart the led kept blinking on off in an exact pattern of 1 second. It took me weeks to figure out the power was coming from my solar powered electric fence over 100 ft away outside. That fence pulsed every second. The closer I got the brighter the led flashed. I thought I found zero point for a few weeks 😂 😂 😂
we forget that if it osillalates it radiates enengy
The fence radiates a huge repeating spike in the electric field. That will light up a lot of electronics that have circuits sensitive to induction. Remember those flashy unpowered bling leds that you could stick on the back of your phone? Same thing, sapping EM energy that passes through the antenna.
power actually flow in the magnetic wave of the wire. many believed the wire carries the electricity it directs the magnetic wave which the electricity flow in waves.
To make this this circuit a little more reliable, i would add a current limiting resistor in series to the LED and two base resistors on the last two transistors. Thanks for this nice video!
The battery has internal resistance. If you know you Vf and desired current and you know your battery resistance then there is no need for a resistor.
Так, и кто мне объяснит, что это за фиговина и как ей забивать гвозди ? Можно её сразу выбросить или пусть полежит на холодильнике до уборки мусора?
I used to test voltage with my tongue. Now thanks to this I no longer have to do that anymore!
Tongue tingles = 9v. Wake up in hospital = 120v. Yeah, video will save you some money and time. LOL,,

Greetings from Australia.
Though these are already mass-produced somewhere- I love the simplicity of it and the possible modification process. Excellent.
What is it an what does it do???
@@frankguerra3314 it's a tester to see if voltage is present or not.
You could use it for many applications, like checking to see if a wall receptacle is live or not.
Many things to test with it.
