omg it works!

so duz the ouija bourd so it dont matter

[schmidtm4]

except you wont get possessed with it. ;)

This thing might not actually detect "ghosts", or anything supernatural, but perhaps it could detect an approaching lightning storm? There are lightning detectors with somewhat similar circuits.

for ghosts, I would definitely want to use a different kind of amplifier circuit. Perhaps a FET as the 1st stage, or an instrumentation amp?

Or simply tune any AM broadcast receiver to a quiet spot (no radio station transmitting), and you will hear all sorts of crackles, pops, humming, etc. Then record the audio to a .wav file on your computer, and run an FFT (Fast Fourrier Transform) on it. You would be surprised with what you can get.

Nice and easy to follow steps! As the video link seems to be broken, i found another video called "the ultimate ghost detector" that consists of +- the same circuit:

Will this device work?I mean,I don't really do these things but it's kind of attractive.
Thanks!

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

[jompon2547]

i am so spooked

[HackShack]

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

[ShraddhaN1]

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

[Salman Naveed]

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

[DineshK11]

R1-10K

R2-100K

R3-220ohm

[Gursimran Singh 425]

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 !

[Matty38]

like a Darlington array

[bravoechonovember1]

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

[Gursimran Singh 425]

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

[Samiran]

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]

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

[Gursimran Singh 425]

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

[Gursimran Singh 425]

Thank you :-)

[Anfas]

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