Giant Induction Coil 5 Feet Away Picking Up Audio.
Вставка
- Опубліковано 25 сер 2024
- Have you ever wondered how far the electromagnetic fields from power lines can be picked up? In this experiment I brought a large coil of wire with me far up in the mountains, and attached it to my audio amplifier, and much to my surprise, I still had a pretty strong 60 cycle AC hum at a great distance from the power lines.
The other reason I wanted to get away from the 60 Cycle AM hum, was that I wanted to see how far a giant inductive coil would be able to hear small electromagnetic signals powering the speaker in my small digital tape player.
For anyone interested in knowing the coil size. I used two coils in this experiment. Each coil was wound on a spool that had 34 inch circumference, and each coil weighed about 6 pounds. The wire appears to be 30 gauge. You can use copper enamel magnet wire, or whatever you happen to have, but it seems that the larger the diameter of the spool it's wound on, the more sensitive it appears to be, and the more turns you have, the more sensitive it appears to be. Have fun.
For those who may be interested, I made a longer version on this experiment in the landscape mode you may find more interesting at this link. • Giant induction coil p...

Some videos are very loud and some are very low volume.
Can you please invent a volume modulator?
A device that maintains the volume level as I move from video to video.
Or from programs to advertisements on TV.
Please,, thank you.
@@benjamindover5676 Such devices already exist.
Did u see the video that states they can amplify the ac hum and cross reference it to a recording to find the exact minute it was played in the past? So if there is an unknown recording of a crime they can play the hum and get the time of the crime. Spooky

Tom scott did the video
This is such a goldmine of a channel. So glad I found this
Thank you. Here is an expanded video on this experiment. ua-cam.com/video/83edokt3K5c/v-deo.html
@@GrantsPassTVRepair thank you!
Me too, me too!!!
Definitely, I'm going to subscribe right now
You said it brother. I was like: "Ah, I'm going to sub to this channel", earlier when I stumbled over the dual diode video and this telephone amp. But then I saw I was already subscribed, it seems. 😅
My old man was a radio operator in the air force. Our home was wired with an intercom system made by the same company. Radio shack love
RIP Raido Shack
If you use a high pass filter, it should eliminate low frequency interference which includes ac power lines. Would love to see this working!!! ❤
Came here to say this.
For me to remember
Could just build a notch filter too JUST for 60hz
Where would he place that exactly?
@@bricesuire5072in series with the coil.
Sparky here. I show my co-workers these phenomena. Some are amused some are uninterested. I find them fantastical. Please keep it coming bud!
Thanks Sparky. Here's an expanded video of this experiment. ua-cam.com/video/83edokt3K5c/v-deo.html
Fellow sparky here, just found this channel but I work in industrial so this is a great way to explain inductance and why VFDs have exclusion zones for any RF signal or EM energy. Eg, "No Phones, Radios, or Magnets within 10m"
@@i-love-comountains3850 Thank you. Here is a longer version of this video. ua-cam.com/video/83edokt3K5c/v-deo.html
I appreciate all the effort you are going through to show us your experiments
Thank you. These are simple fundamentals of electronics, but still a lot fun to experiment with, and ponder the possibilities.
I second that💯
That is crazy you can still pick up 60Hz! At my work we have these cable toner / inductive amplifier. You can connect it to a long run of network or phone wire, and you only have to be a few feet away from the cable to pick up the tone.
Some day I'd like to see how many miles one must travel, to avoid the 60 cycle hum from the power lines, or perhaps I can wait until the next wide spread power failure,
@@GrantsPassTVRepair I honestly don't think you could
I have one of those toners too! Very useful on the job, and kinda cool too. It’s like you have a 6th sense, you’re seeing through walls with virtual photons and your ears.
@@GrantsPassTVRepair It's 50 Hz in Europe and other countries
@@nethacker91I'm fairly certain that he is well aware of that. So are many others in the electronics and electrical fields of work and study. 😊😅
This guy is not your typical tv repairman.
That's for sure ;-) TV repair paid my bills for many years, but my first love is experimenting and pondering unrecognized possibilities.
This stuff is really cool. Thanks for showing us.
Thanks for watching!
I had one of those suction cup inductive pickups way back in time. I used to use it to pickup the soundtrack from the movie speaker at a drive-in theater and record it onto a small reel to reel tape recorder.
I hope one day I have as much time as this guy to drive to the middle of nowhere to shoot a UA-cam video. Thank you.
What do you mean by saying "not bounded"?
I'm guessing you spent too much of your youth haunting Radio Shack as I did.
Nice production and nice view up there. Thanks and a thumbs up button.
Thank you, and yes I was a big fan or radio shack. I still own some of their 200 in one project kits.
Found your channel and its giving inspiration for my final year electrical engineering project
That's nice to hear, Other than becoming a TV and electronics repairman, I never took this hobbie that far, but all the best in your pursuit if that's your calling.
The 50/60Hz wavelength is so long that it will travel REALLY far. A pain when trying to do any instrumentation work!
Great Video!
Grants Pass is lovely country. This from a Northeasterner who lives on the coast at 20ft elevation. I was on the Stouts fire in Canyonville and we drove through Grants Pass after demob to another fire. We stopped somewhere to eat in town (I can't remember exactly where now) and they gave us half off our meal. Just a great group of friendly and appreciative people.
It really is a paradise here, but all those trees seem to mean forest fires most every year.
In the 80's I made a VLF radio receiver, which was basically what you have here. I did need to get miles away from power lines and even interference from electronics. I could hear many things. Crackling Atmospherics from distant lightning, Tweeks which are quick descending musical notes from distant atmospherics which had been ducted to my location along the earth's magnetic lines of force. Whistlers which are a little longer than tweeks and may be a descending note or sometimes a whoosh sound. It was quite amazing.
That sounds like a lot of fun having such a receiver, but I never thought about the problems of using one near the power lines.
U should try adding a low pass filter set at 60hz to remove all the annoying buzzing! U can pick them up for dirt cheap and there are even filters designed specifically for that frequency. I have one in my car audio system I built to send different frequencies to different speakers, super useful.
Excellent videos thank you
Glad you like them!
I used to have one of those telephone listeners! The exact same one from Radio Shack. I used to use it to listen to what was going on in my circuits. In all the intervening years I still haven't been able to afford a scope. One day.. Anyway, using a coil from a small 12 or 24 volt relay gives incredible sensitivity. Keep experimenting!
I've been using inductive circuit probs for years. Here is a video I made on this topic.
Anyone else see Bigfoot in the background? That 60Hz tone just drives them nuts! 😂
Your mind is beautiful
Nice Camry. ❤❤
Occasionally in band rehearsal I've held my cell phone near the bass guitar pick-up coil and played music through it to my amplifier. It sounds very clear.
Great idea!!
You're awesome man
That’s incredible. I always wondered what kind of waves were in the air all around us.
Lots. Lots and lots and lots.
It also could be Greenville or greenbank but it's a place in West Virginia where radio frequencies aren't allowed and the radio frequency square actually reaches over into Virginia
This was phreaking cool!
This channel is low-key spy tech 👍
Digital recorder,...but this is still cool to watch. Keep it up,love this stuff
i love this man!!!
I have that same inductive pickup! I bought it back in the early 90s at Radio Shack.
I made 'spy' recordings as a kid using induction coils from a diagram in a popular science magazine. It worked but I don't think I ever really understood how, until I watched this. Interesting, Thanks;! 😉
I remember back in the day people complaining about headaches and hearing a hum as they were putting up towers and it was definitely a real thing because with anybody who had a disability when it comes to frequencies what should be a variety of things in the air and we can hear them a little bit and it can keep us up at night or give us headaches but the animals and the insects they really suffer
You are a genius. I love your vids you make me want to experiment. 😊
I agree! He’s awesome!
You are my Teacher ❤
Now you know some military secrets. It was nice watching your channel. 😂😂😂😂
Man, I wish I could hang out with you and have a cold beverage or three 😅 thank you for sharing-closest next best thing!
It's nice to hear you're enjoying some of these simple fundamentals. Thanks for the comment. .
My favorite channel.. I love all your experiments
Thanks much.
I don’t have plans to be a father at 30. I know it’ll happen unexpectedly but when I have kids this kind of tinkering is what I hope to get them into
Same here. As a kid my uncle got me started off with a crystal radio, and then a 10 in 1 electronic kit, and soon after that CBs and ham radio became a hobby. All the best.
@@GrantsPassTVRepair My only grandfather I had was a total nerd. The only in our family of “city folk”. He took me to the DC metro to the Smithsonian mainly to go to the Air & Space museum. As he was in the Air Force but I was too young to even know what that was while he was alive. I just knew this guy loved computer and planes. He was the only father figure I had until I was 10. I live by that man to this day. He wasn’t afraid to be curious and test things out.
He got me into electronics when we found a car in the woods and he taught me how to use separate car battery on another trip back to turn the lights on this old car with a tree growing through it. I felt invincible connecting the wires from the working lights to a car battery seeing the car come back to life.
Unforgettable moments from curiosity.
Meanwhile in the mainstream of my life I had uninteresting things thrown down my throat wasting the potential space I could have used in my noggin.
We’re human. We don’t like to be told what to be taught. We like to play around until we get curious. That’s how you inspire
First video I've watched from this channel and I don't think I'll watch another... I'll binge the lot!
Subbed!
Hahaha
Miss those hills and mountains.
That's interesting and scary both. Thank's for the information how to get spied on 😂
THis wouldn't work for that, it's not anywhere near focused enough
You'd just get a stupid amount of noise
@@viperfan7 good to know
Of society collapses I need this dude!
Cool hobby 👌
I love this channel. Ive never wanted to learn so much from curiosity
Happy to hear that! I appreciate your comment.
Hi there; if you’re in Grants Pass then you are close to what we in the power industry call the COB, the California Oregon Border Interconnection.
The 500-kV transmission network, running from BC, through the Pacific Northwest and across California and into Arizona and Nevada packs a lot of traffic (and 60-cycle hum) through your neck of the woods….
One day I'd like to take a long drive far from any power lines, and see if it's even possible to escape the 60 cycle hum when using a large induction coil such as what I used, or perhaps wait until we have a wide spread power failure.
@@GrantsPassTVRepairI'd bet on the power failure, unless you plan on going way out on the ocean somewhere, or the middle of nowhere in Siberia, the North Pole, or Antarctica. Otherwise, there's just about no landmass on Earth where you'd be able to avoid hum (whether that location is using 50Hz or 60Hz standards) completely at this point. They're widely used specifically because energy in that frequency band propagates so well through the air, making it nearly impossible to escape completely.
@@Guynhistruck After what I witnessed, I would not be surprised to find out you're correct. I produced a slightly longer video on this experiment at this link. ua-cam.com/video/83edokt3K5c/v-deo.html
Nice to find this video again. I was going through some of my dads collection of random electrical parts. Found the phone listening device like you first showed. Then found one l, but it was a flat bar with wires coming off it. Still had its box and instructions. Not sure how old it is.
Maybe it's picking up your camera. Excellent experiment!
The only thing my large induction coil picked up from my camera from a few feet away, was the audio coil driving my camera speaker.
@GrantsPassTVRepair I bet you can make some really cool HF antennas! I really like your experiments 😃
this is very cool, I have heard of this technology before for communicating underwater with divers as radio signals wont go though the water but magnetic fields do, so I have been looking for a simple way of doing this to control RC submarines.
More accurately you're still using radio waves, just much lower frequency. Higher frequencies are typically blocked easier. The more salinity of the water the stronger its blocking will be as well. Physically speaking even if you don't describe it that way any and every electromagnetic interaction is mediated by photons, i.e. electromagnetic radiation, i.e. at lower frequencies radio waves.
@@xxportalxx. ulf is already used for communicating with subs at sea, i just want to get to the bottom of the pool lol
Ultrasound (very low frequencies) travel through water. Think of the sounds whales make that travel hundreds, maybe thousands of miles. Is sonar used under water??
@@moonmagnolia7 yes thats the normal way of doing it but its very slow and difficult to do at small scale.
Havent seen the valley in too long!! Funny, decades ago we'd of been competitors. I had a tv/vcr shop out in CJ for a few years...😂
Build another one wound the opposite way and use them both like a giant humbucker guitar pickup the noise from one coil gets canceled by the out of phase noise of the other coil. This is such a cool idea I don’t know much about electronics but I do play guitar and know there’s always a way to get rid of that 60hz hum.
I tried this, and it did work to some degree when both coils were pointed in the right direction, but the coils need to be identical.
@@GrantsPassTVRepair good luck with this it’s such a cool project! I look forward to seeing more of this and anything else you decide to do. It makes me want to get more into electronics. Cheers!
I like the fourth wall breaking
This is fascinating. Gotta hate the humm, though. 😂😂
Ahh, dudes doing fun projects... subscribed.
I think it’s super cool what you’re doing, you’ve earned a subscribe.
On the other hand, you’re in the mountains and I’m not. I’ve got cabin fever like never before! I live in Utah at the base of the Wasatch mountain range. In the summer I like to spend every weekend in the mountains. I find the mountains just recharge my “batteries”. I have some really bad depression, especially right now, and need some time up there. Unfortunately, the area I want to be in is still covered with almost 5 feet of snow. 😢
I can relate to everything you said about cabin fever and depression. We had a long rainy winter here, so I've been looking forward to seeing some sunshine, and getting out in nature, where it's just me, and God, and the cares of the world seem unimportant.
@@GrantsPassTVRepair Thanks buddy, much love!
You need to go to a beach in Florida and soak up some sun/vitamin D. That’s help get rid of depression.
Very cool! Ah grants pass. Gotta love that place
Awesome
Yes, magnetic field is infinite, just dwindles in its strength the farther from the source. Very unique and interesting.
I've the same Radio Shack telephone listeners hooked up to a HB100 10.525 GHz microwave module, plenty of fun using it as a speed gun or hearing the doppler shift of objects through walls
I need one of those. My home has the weirdest acoustics. I can hear a low frequency thumping when I’m near the toilet in one bathroom, but if I go outside or in another part of the house, nothing. I figure the walls have that area have refracted(?) the frequency of that sound to a level I can here it. I think it’s coming from a factory about a mile as the crow flies.
Ever use a Chassis Ear? If your car is making a weird noise you can clamp these little wires to the suspected part and drive around with headphones on to hear if its a bad bearing or a squeaking bushing or something. Picks up any vibration or rattle. Works awesome! Just gotta be careful itll blow your ear out if the volume knob gets bumped. I always pretend im running the sonar on a submarine when i get it out 😂 I hear splashes... depth charges incoming! Dive Dive Dive!
So cool, this is using UA-cam to its full potential ❤
How does this even work?! You've surpassed my general knowledge.
It's called electromagnetic induction. It's the same principle that operates transformers,
What’s a transformer, hahaha? I love learning about electronics. Obviously I have a LOT to learn. Thank you for educating us. 🥰 Yes, I’m a girl.
@@moonmagnolia7 My pleasure. Thanks for the comment.
Dad bought one of those phone amplifiers for his sister who lived on the opposite coast. It was hilarious to hear him screaming at her the instructions for setting it up 😂
my new guitar pickup!
Very cool video keep up the great work 73
RADIO SHACK STUFF!!
I had multiple of those taps back in the 90's connected to tape recorder's, no one was catching me saying I said this or that 😅 here's my tapes and all backed up
That's mind control hum. Lol
That's not powerlines, that's the cosmic microwave background radiation 😸
all that EMF.....blasting through our brains
SUBSCRIBED -- I NEED MORE OF THIS
Hmm, the power grid forms some pretty large loops that are dozens of miles across, but at best 3 turns . Then there might be a power cable under the road feeding someone higher up the moubtain . Try turning the coil to find the source .
There were no power lines where i was at, but perhaps a mile away by air there may have been.
Giant guitar pickup
That's one heck of a tape recorder. Lol.
You're going to get static anywhere on earth at least from the Schumann resonance, will have to make a band pass filter to clear it up completely
I feel like I'm part of the FBI watching this, even if it's just on a list 😂
Awesome!
David, the hum isn't from transient AC! They're here! Disclosure now! They want our cheese!!
Yes they do, but If there is any escaping the 60 cycle force field that surrounds this planet, we may have a chance. ;-)
Awesome 🎉
Thanks 🤗
Kind of what Tesla had that allowed him to receive ideas for his inventions... but a smaller scale!
To get out of range of the AC hum I honestly think you would have to leave the planet. I would not be at all surprised if you could still pick AC on the moon. Considering all the wattage pump through this planet there is a chance that even the Voyager spacecraft could pick up.
Crazy to think this is the same technology the FBI used to use to record phone calls.
That first Archer unit made it so you could play Charlie from Charlies Angels.
THE 60 CPS IS COMING FROM GROUND . WHEN A LIGHTNING PROTECTOR FOR YOUR HOME PHONE SHORTS OUT TO GROUND YOU WILL HEAR THE 60 CYCLE HUM ON YOUR PHONE . GROUND HAS MINERALS THAT CONDUCT ELECTRICITY REAL WELL. EXAMPLE : HOOK UP A 120 VOLT FLOOD LIGHT TO HOT IN YOUR HOUSE . RUN NEUTRAL TO A 3 OR 4 FT ROD DRIVEN IN YOUR YARD . HOOK THE NEUTRAL TO THE FLOOD LIGHT AND THE FLOOD WILL LIGHT FULL BRIGHTNESS.
Essentially how an am receiver works. :)
In that case, that’s not a coil, it’s an antenna . It’s called Lf loop antenna.
You need a 60Hz notch filter
It's because the earth is flat. Thanks for the experiment
Bro, you're, Inductor is half the size of a 55 gallon drum.Of course you're going to hear a/c A mile and a 1/2 in any direction of a power line.😅😅😅 Pretty cool though
You can pick the horizontal and vertical frequencies of the CRT screen and reconstruct the image.
Yeah building your own analog TV is fun! Unfortunately the vast majority of TV stations no longer broadcast an analog signal.
You might want to add some filter. Capacitors or an isolation transformer.
These radio waves/AC waves can be used for zero point energy!
A man in Africa created a car that runs on only natural atmospheric energy that surrounds us all.
He also created a T.V. that never has to be plugged in!🏅
I don't believe his invention is real. UA-cam is full of con men.
@@GrantsPassTVRepair I promise you it's real. The guy came to America trying to get his invention pat. Now he is in hiding.
The either is the future 💯
I mean, its basically just an unfiltered radio receiver, really close to a crystal radio
How many turns of wire and what sizes?
I used two coils in this experiment. Each coil was wound on a spool that had 34 inch circumference, and each coil weighed about 6 pounds. The wire appears to be 30 gauge. You can use copper enamel magnet wire, or whatever you happen to have, but it seems that the larger the diameter of the spool it's wound on, the more sensitive it appears to be, and the more turns you have, the more sensitive it appears to be.
This is how a radar detector detector works
When I was a kid I had one of those. Bought it from a neighbor.
I've got one of those Archer intercoms.
Havnt seen first act in a long time
Looks like where i live, up in siskiyou county California.
I'm in Southern Oregon.
