Introduction: REAL Ghost Detector

Picture of REAL Ghost Detector

I don't believe in supernatural things but after reading too many books and articles about the reality of ghost I came to know that ghost are not like they appear in horror movies! but actually it is a form of energy that gets converted after we die.As we know that energy can neither be made nor be destroyed,it only changes its forms.After we die our organic energy stored in our body as fats and proteins get burnt or mixed up with soil,but what about the nervous impulses that run in our body when we were alive.That's the soul or presence of charges i.e static.It is true that whenever there is a soul the temperature of the place drops suddenly,also you might have seen it in "The Conjuring" movie.Great scientists like Edison and Einstein too believed in existence of souls (in scientific way static charge).Lat year I read a document in which a person had written about souls,saying when his fellow died his weight dropped suddenly ,in our universe matter occupies space and has some weight.The soul had occupied person's body and when he died it got free from it and weight fell down suddenly.This seems to be contradicting!There is no destination after death neither heaven nor hell.Fortunately science has made live present heaven on earth by giving precious gifts to life.Says Osho.Our soul never rests it keeps on wandering here and there in search of perfect body.But no need to fear from these as it is a natural process.If you want more knowledge then you can read material about "Reiki".This device is a static detector only which can detect variation of charges present around us.It glows brightly when positive charge comes in contact and becomes dimmer or blinks when negative charge approaches.Here are some videos which show the functioning of device.The intensity of variation depends on amount of charge in it.

Step 1: Things Required

Picture of Things Required

We need :-

  1. 9 volts battery
  2. 9 volt battery connector
  3. BC547 transistor (3x) or equivalent
  4. 1 million ohm resistor
  5. 100 kilo ohm resistor
  6. 220 ohm resistor
  7. slide switch
  8. small box
  9. l.e.d

Tools required :-

  1. soldering iron
  2. hot glue gun
  3. a pair of pliers

Step 2: Schematics

Picture of Schematics

See the schematics and diagram above this will make you clear about all the connections.I would truthfully say that the schematics is from Saiyam's instructable and the from talking

Step 3: Making the Prefboard

Picture of Making the Prefboard

For a simple board use cardboard and make the holes after seeing the schematics and hole must be larger enough for the pins of transistors as well as resistors to pass through them.Make it on a medium sized cardboard.

Step 4: Soldering All Components

Picture of Soldering All Components

Place all the components as shown in the picture and solder them carefully.Make sure that the connections are right match them with the schematics diagram.Check the pinout of the transistor firstly.

Step 5: Add Other Components

Picture of Add Other Components

Now, some other components such as l.e.d and battery connector are left from being connected to circuit.Carefully solder all the components and make your device more efficient use old antenna as antenna connect the base of T1 to the antenna.Note I had changed the l.e.d as in first one the difference was not noticeable.Use one color l.e.d other than the blinking ones.

Step 6: Fitting Everything Inside the Box

Picture of Fitting Everything Inside the Box

Take a small box in which all the components can fit.Make necessary holes using a soldering iron for l.e.d ,switch,antenna etc.Make everything fit inside the box.And if necessary then use hot glue to join the circuit to base of the box.

Step 7: Ready!

Picture of Ready!

It is ready for your ghost hunt.For testing it is ready use scale after being rubbed to your hair,your hand,positive and negative terminals of the battery individually etc.

Step 8: Something Is Missing!

Picture of Something Is Missing!

Yes ,only switch is left.Make a hole in box's upper part and using hot glue seal switch to the box and make the switch between circuit board and battery terminal.Test it again if anything had gone wrong !

Step 9: Done!

Picture of Done!

The ghost detector is ready! Just press the switch and go for a ghost hunt.If any static charge is present it will either become brighter,dimmer or will blink which is result of approaching positive ,negative and powerful negative charge near.The device will become more efficient when battery starts running out as the change will be noticeable then.It is working device not the fake one! I welcome ideas and improvements in comments.Happy Halloween Day in advance!

Who'ya gonna call!? I like the idea, but all you need is a staunch Christian staying in the house

i am so spooked

RibrobYEG made it! (author)2017-04-02

I built one of these for my youngest boy and stuck it inside a large waterproof pill container. I told him it was a lightning detector so he wouldn't get spooked if it went off while he was alone with it. It really lights up when I get off my couch even across the room from it.

Can I use a pn2222? I have a bag of those.

AniketD19 made it! (author)2016-10-17

Can u explain the working of the circuit with gain .also how led is glowing by touching the antenna with hand means what is the value of input in volts from the static charge or by touch of hand and as well as gain.pls explain with mathematical values.

ShraddhaN1 (author)2016-08-29

i was thinking of using an arduino to do this. Woud you mind guiding me to do so?

Salman Naveed (author)2015-10-12

Can you tell me the correct sequence in which you installed the resistors from R1 to R3? Great project by the way!

DineshK11 (author)Salman Naveed2016-04-27




Hi,thanks for asking and sorry from my side for delay in reply!all the resistors are connected one after one to collectors of transistors and from the battery

r1 is 220 ohms

r2 is 100 kilo ohms

r3 is 1 million ohms

thank you !

I made this small circuit. Of course, this is not a ghost sensor, at
all - there is not any circuit to detect a non-existing thing - but a very interesting little system to detect very
weak signals around us. The circuit is based on the Darlington-circuit, when the gain of the transistors will be multiplied, creating a very sensitive electronic detector with ever some millions gain, and almost infinite input impedance. This circuit can detect not only the well known "electronic garbage" and the usual magnetic or static fields of household machines and gadgets, but a very interesting phenomenon: when I lift one of my foot from the carpet to do a step quickly, the led lights on: first I couldn't recognize, why, but then guessed: if the sole of my slippers leave quick enough the carpet, a capacitor will be created, dividing the electrons of the surface - this may cause the sparkling hits touching a metal object in the museums and shopping centers too, when you walk on a well insulated corridor for a long time, wearing plastic sole shoes. At this situation the electric charge may gather in your body, multiplying step by step - but now you can detect only one (very small) amount of this charge causing one small step:-)

This is more interesting phenomena, than a "detection" of non-existing ghost never proofed "presence", anyway...

like a Darlington array

bravoechonovember1 (author)2015-10-06

this is not REAL it is picking up signals from a static charge

if you walk across carpet you make static electricity so it isn't a REAL ghost detector

Right that's the problem with it,but charge while moving over carpet or rubbing box with hair is not that much! If ghost exists then the amount of charge would be more

Actually you have made a high gain amplifier. It will also detect wires which are charged. This will be contact less voltage detector. Hell & Heaven is all here dude! It will also react to MMF = Magneto motive force or magnetic stress. Any way nice way to present your work. Well done.

samtechpro (author)2015-10-07

its not a ghost detector its just a device that detects EMF as i did in the post few years ago. i made the same thing for high emf detection

Its name depends on how you use this!! Nice use!! Thank you

PALASH BAURI (author)2015-10-08

Cool n smart

Thank you :-)

Anfas (author)2015-10-06

Bro...this is really cool...but please do tell me how do we distinguish between positive and negative static charge when the LED glows?

Hi,bro whenever positive charge is present then it brightens and when negative approaches then it will either become dimmer or show a little blink,we canuse this to ffind mains too! Thank you too much! :-)

izamry (author)2015-10-06

there is hell in heaven when we died ..... subhanaallah .. we will see someday dude ... i hope u find hidayah ... go find what is the meaning of "hidayah"

Anfas (author)izamry2015-10-06

Dude...go display your islamic values somewhere else...I too am a muslim...but don't bring religion into science...It sucks that way,,,honestly... :D

tali7 (author)2015-10-06

in your circuit diagram the diode is shown but there is not in your components

Sorry,I had used blinking one first but it didn't worked so I changed and forgot to change it in components list ,I had shown transparent l.e.d here!

tali7 (author)2015-10-06

please ask which diode is used in this

Less power consuming l.e.d

howtoraju (author)2015-10-06

Thumbs up man

Thank you too much friend!!

alexkirlian (author)2015-10-05

where's the electronic scheme ??

2nd picture of step 2

shaque2 (author)2015-10-05

I cant understand it .where you can put the antanna

The antenna is joined to the T1's base and joined on top of box using superglue

allybongo (author)2015-10-04

and god is real, fact! lol

Oh yeah !

mist-man (author)2015-10-04

I recommend reading proper scientific articles in the subject. There you will find the precise understanding of paranormal activity that books or general articles fail to recognize.

What I had read,I had written but I don't know what is truth and what is not! Search for pdf files,you would surely see some of the content similar to this one.Thanx for showing interest! !

euvremer (author)2015-10-04

It is a tension detector, made to detect electricity or electrostatic charges in walls

Exactly! !

dmwatkins (author)2015-10-05

Can you cite your source for the bold print statement?

listen to some of lectures of osho,I don't know exactly which one was that. Thank you for showing interest!!!

fred3655 (author)2015-10-04

Anyone who doesn't believe there is a hell has never been audited by the government.

Weight does change upon death... because the muscles relating to the excretory system relax... jussayin'
