Didn't find any ghosts in the house... found a few skeletons in the closet though... lol my bananas had a charge on them in a metal fruit bowl... interisting
Thanks for the video! I just found you via some ham radio video suggestions. Would this work as an uber-sensitive field strength meter to test if things like LED light bulbs are emitting trash RFI? The noise floor at my house is usually really high and I'm needing to find some sources of the interference. My relative DIY relatie RF field-strength meter isn't sensitive enough to do the job.
Hi, I'm looking for a solution to detect AC or DC current in a wire (= 0 Aamp or >= 0 Aamp ) without contact to the copper with an hall effect sensor. I'd like to use à ESP8266-32 to get ON/OFF information. I'd like to detect that electric machine status is on/off without cutting the wire (just by gluing the sensor on the wire for example) Do you have any recommendation, video in you pocket ? That's a subject for the next video ?...
I was looking for something to detect how much of a charge electrostatic filters still had. Potentially it would give me an idea If a n95 mask was still usefull. I put a volt meter across the diode to give me a digital readout. What I've noticed is that I seem to get a strong reading when I move the filter about an inch or two away but the signal dies when I stop the movement. I seem to have to induce a current thru motion. Is that an expected response?
I did want to mention awesome video keep up the good work my TH-cam brother.. Please keep in mind I'm just starting out building ghost equipment and learning circuits and sauce.
I know this is an old vid but i wanted to try it as im just learning but i could not for the life of me get it to work. The components i got are exactly the same as listed, but once assembled the led is on all the time. I tried looking for shorts but there are none, i checked the transistors are in the right way, i changed the transistors incase one was faulty. I tried over and over with the same results. What am i doing wrong? Why would the led be on all the time? Thanks for any help
Your bias on your 1st transistor is too high. Either your pickup wire is too long or you use higher voltage or you have too much interference from RF or static
Thank you for sharing your knowledge. Tried this. Burned the led. The total hFE of the transistors is 428*429*357=65,549,484 gain ( with 698mV each). The led Uf is 1.92V. What should I do?
Is it possible to built some speakers 🔊 that would amplify my cellphone sound conecting it wear the headphones go on theirs and app goodve that amplifys your sound nice but I want to invent some what iam telling
learnelectronics in that is uses transistors, yes. :D. (sorry I couldn't resist that). I think he just did two(Darlington) but he explained something about touching the antennas together to shut it off or put it in such a low current mode it was virtually off. It was a neat finished product almost. Yours is a bit more interesting though, I want to look into them both and try them when I have the time. Even before you said it I thought "he's making a ghost detector'. Of course you didn't let me down!
I USE TO HAD ONE OF THOS E AND ITS A TOY ONLY IT DETECTED WIRES IN THE WALL BUT THE LIGHTS WAS PRETTY MUCH ON ALL THE TIME AT ITS 50% SO I WOULD BUILD ONE WITH CHIP OR SOMETHING MORE SENSITIVE .........
Wow that's some serious amplification! I think I'll build one for my wife who is always watching the ghost finder shows;. Thanks for a fun project!
do you think you could add a buzzer / speaker/ one of those small disc-like speaker you get in christmas cards to this build, and how ?

It is not super sensitive. LEDs aren't a source of RFI but their power supplies sure are.

@ learnelectronics Would this work to detect lightning strikes?
How could you add more led's so as the signal gets stronger if goes up from 2 green(low) to 1 yellow (med) and finally 2 red for max?
Love it, making electronics fun is what it's all about... 👍🏻 Ghosts indeed... 👻 😂 🐍
Any particular reason you used a 220 ohm resistor on the last transistor
220r is about the best resistor for an led @ 5v... So it works well for 6v too
Bingo

Should introduce a 358 Amplifier chip.. That way you have a little more gain.. you wouldn't have to be so close to the antenna...
Love this simple project...I shall try it
Thank you for sharing your knowledge. Tried this. Burned the led. The total hFE of the transistors is 428*429*357=65,549,484 gain ( with 698mV each). The led Uf is 1.92V. What should I do?
Increase the led resistor... Try 1k
Thanks. I tried 1k and 220k+300k and led shined (my mother in law was around). Then I tried the 220 and it worked for some time (the led is 3.7v now).
220R+300R...

I'm not an audio guy sorry
If I ever come to your house I can certainly help you get rid of your spirits! ;-)
I have 9v clips and a 100pk of those transistors...small weekend project!
Next you need a proton pack and a ghost trap then you will be all set LOL
You can leave the insulation on the wire
Did you see big Clive's ghost detector with the old TV antenna?
No, is it similar?

Ha ha great! I'm glad you enjoyed it.

Thank you for content. I made one by your tutorial.
Out of this circuit can you make a super Joule thief from it or can you make a super Joule thief.
now to calculate the gain of that amplifier :P
You've lost your battery clips, my transistors have gone walkabouts! Fun project though, I'll be trying it soon.
Well.. you do realise what happened.. Ghosts took them so you couldn't make one and detect them.
John Bailey haha! I love it.
I have a 9v battrey clips and a bjillion of those transistors. (RIP batttry clips.)
Ghostbuster.
Who you gonna call?
