Olmlmo EMF Meter Review - Testing Household Items For Electromagnetic & Radio Frequency Fields
Вставка
- Опубліковано 6 сер 2024
- This little gadget measures Electric, Magnetic, and Radio Frequency fields. I was curious to see how it works and what I could use it for. Unfortunately I couldn't find much of a guide to actually using these for anything in real life, most of the info online seems to be from questionable sources.
The unit itself does seem to respond to electrical fields, static electricity, strong magnets (but not fridge magnets), and various radio devices.

I check the RFI around my house by just using a portable AM radio. Tune it to static and walk around the house RFI will cause the static to change.
I was getting a clicking sound when receiving on my 2m radio. Searching the house lead me to my air filter that had a dirty negative ion plate causing my RFI.
Also: the mesh is to big on the catio to work as a faraday cage for the frequencies you are looking at.
Thanks for the video, Hello from Finland
I would love to see the inside/circuit board of one of these.
You just gave me a great idea for an artistic project
A company called SOMA sells an "anti-radio" called Ether, it lets you listen to the power grid through a bunch of antennas crammed together. It's meant to be a toy for synthesizer enthusiasts but it is a lot of fun and would be a great pair with a device like this.
Interesting! I'll have to look into that, it sounds fun. I just use my cheap computer speakers to listen to radio interference. They always know when a text message is coming in, before the phone even beeps 🤣
This show makes my day. This is my favorite UA-cam channel !!!
❤ Again a nice review in the old nice saveitforparts way 🎉❤
Great video man. Every video I've watched of yours is very informative, also the radioactive cat was funny lol
4:36 Love the shirts!
Great video!! The screen needs to have smaller spaces in between my friend. You don't want your cat picking up CB radio traffic..lol
We definitely need further scientific experiments with your cats to determine why one is emitting RF but not the other. 😂
Probably static charge on the cat? Kind of interesting device but practical? Hrmm...
Cool video, man.
cool vid!
I wonder if this could be used to find QRM when troubleshooting RF in the hamshack. Maybe could be used to find particularly noisy electronics like LED light bulbs
Hey I still use CDs. Never thought to play them over a CB though.
OK, but wanna go hunt some ghosts with it? lol
Lol you read my mind you tested the cats
Now all that's missing is a REMPOD, a spirit box, a few cat balls, and the ghost hunt can begin. America is said to have many haunted and creepy places where spirits reside. I'm already looking forward to the ghost hunt videos. 😁
Is Donnie microchipped? They typically insert RFID tags between the shoulder blades on cats when they get chipped. Otherwise you may have a synthetic cat on your hands! Neat!
They're both microchipped, maybe one has more static electricity than the other :-)
Dude, cat's aren't real - cats are soviet drones, and birds are US drones. That's why cats attack birds - duh...
Does the kitty emit anything? 😂😂😂
Not to mention light is an EM field too! 1000 watts per square meter in sunlight
If the magnetic mode isn't detecting much from the cellphone it's probably not sensitive enough or doesn't have a wide enough frequency range. That was what I typically found when testing EMF meters. A smartphone can emit more magnetic fields when you use it, like scrolling pages or opening apps or something. If you don't do anything with it it may be a lot less. But often cheap devices cannot measure all magnetic fields because the frequency range of the device is too narrow. So you may think something doesn't make magnetic fields while it does, and it can be a lot. Some devices are misleading.
I found many specs of devices to be very inaccurate, false claims.
They claim this device has a triple axis magnetic mode and that it can measure frequencies up to 100kHz. If that is true that is pretty good, in theory.
But the only way of knowing it does what it claims is comparing it with other devices, preferably more expensive devices. That is what I found.
At a first glance seeing your video, I think it lacks sensitivity.
Since the official guidance is to not use a cell phone next to your head for a phone call I would be curious to see what Bluetooth earbuds and headsets produce when in use on a call.
I’m new to your channel and really enjoying it! I have a working metal detector that I never use. Any ideas what I can create out of it?
I haven't done a whole lot with metal detectors, so I'm not sure!
Stock configuration I could detect cars from 50 feet away. With a larger coil you may be able to detect them from farther, if you need something like that.
I’m just looking for ideas. @@OverUnity7734
That manual is talking what's known in the UK as "a load of old bollocks!" Standing near a wire at 50 Hz is less damaging to your body than a wire at 100 Hz? WTAF?
A Faraday cage that blocks all RF is also called a _grounded metal box._
It's a fru fru detector - it detects when you have more money than brains
I need something to find underground sprinkling lines they are black ABS plastic but some of the connections are made with stainless steel hose clamps I was wondering if a metal detector would work but is there something that would detect the water flowing through the pipe?
You might be able to use the water as a conductor for a radio or electrical signal, just don't zap yourself!
Try it by your smart meter on your house.
Can measure magnetic field on certain place???
On mountain for example
ever hear of phyphox? its an ap and it boasts a lot of measuring devices for em and physics using a phones component technology. think its useful. i'd value your opinion.
You have beaten LTT to EMF testing xD
@2:48
I guess that Donny likes to connect with strange devices, while Fluff goes into *'airplane mode'*. (And is old enough not to have Wi-Fi when in airplane mode?)
Is it possible to use this device to build an EM imager, similar to the RV dishe one? Does it have any direct way to interface with a computer?
I don't think there's a way to hook it directly to a computer, but that could be an interesting idea!
Why are the readings on the electric setting 3 to 6 times higher when my friend points it at an appliance than when I point it? Sounds bizarre but we did it several tes
Are you sure you're not a ghost? 😂
2:53 Looks like Donnie is wearing a wire, you've got the spooks attention and they turned him into an asset.
Probably a soviet controlled drone. Just like how the birds are US controlled drones. That's why the 'cats' (aka soviet drones) attack the 'birds' (aka US drones). I'm sure there's a numerological answer too if you add up the numbers that correspond to the letters C-A-T and B-I-R-D, but I'm not an expert numerologist, so I'll leave that as an exercise for the reader
I secretly can't wait for the day when you start hunting ghosts though 👻
Every time I hear a strange noise in a mysterious tunnel it's just someone I know drinking a beer 😂
Would this be good tool to find and repair robotic mower's boundary wires?
Maybe, I've never played with something like that, but if it has a radio or electrical signal in the wire then this would probably find it.
Can this be used to find "bugs" in a room, like spy cams or microphones (listening devices)? Say, when one's using Airbnb or hotel.
Maybe? It depends what they're using, if it's Wifi or radio then this should pick them up if it's right next to them. If they're hard wired then it wouldn't work as well.
There are better units out there for that purpose.
company needs to rename itself
Don't the size of the holes in the wire cage have to be smaller than the wavelength of what you are trying to shield against? Kinda like the shielding in microwave oven.
Yes - that mesh on the wire cage is HUGE - that basically lets everything through. You need window screen or better to be effective, AND it has to be well grounded. You can't just throw up random sheets of screen on a wooden frame and expect there to be ANY faraday cage effect. Real faraday cages are built out of very fine copper mesh, and have crazy all copper seals with many contact pads all around the doors. The are INTENSE
The window screen is aluminum, but I'm not sure how well that blocks RF vs copper.
I want to buy olmlmo emf meter from Bangladesh. Please let me know, How can i buy it.. Im waiting for your reply?
Oh man, you totally need at least the cheapest official Zeeko store TinySA and a NanoVNA for the antenna fab. TinySA might be more like a TSCM device that's cheapo, though can be effective like the higher end SDR's without the laptop.
Dony's mind controlled? 🙂 As my old neighbor whose dead had noted about my cats, or maybe was a cat the more I think about, being a California cat when it sounded like was trying to talk and not even in heat like the crazy sounding ones. Maybe it was the microwave hearing effect or something? I doubt the CIA cat got hit by a car and that project never moved forward.
Anyways, I wonder what the frequency range being measure is that's more accurate?
I think the pulse train and other effects that actually couple with electrophysiological effects, versus like most think diathermy effect or whatever heating RF power being the issue, it is not. Not that diathermy effects aren't an issue as well.
You could stand under a power line and see what it reads.
If you want to see power lines being measured, I tested that with about a dozen different EMF meters.
Your faraday cage is missing a couple of sides of wiring, that might be why is not working :D
1:08 BUAHAHAHAHAHAHA SUFFER!
If I recall correctly, faraday cages need to be copper and the size of the mesh affects what frequencies it works with.
I was goofing around with some old 12/2 romex. I made a faraday cage over too of my weber mini grill. I put it over my smart meter before I went inside for the night.
The next day while at work, my surveillance sent a alert. The electric company was there, and the guy was in my backyard looking at my meter.😂
He took my faraday cage with him when he left.
dont we all hate vague manuals dont start vaping or smoking but It started vaping as a alternative but the manuals are extremely vague it doesn't tell you what mode dose what it just tells how use the menu thats it i dont know what this bypass mode is for on my vape even the e manual is the same
so is not conclusive for ghost readings then? ah man
My microwave is conclusively haunted ;-)
Does Donny have an RFID chip?
Both are chipped, I guess Donny just has more static cling 😂
Be alarmed! Be very alarmed!
It's like the smoke detector that goes off whenever you think about using the oven. When I worked in residential leasing, anything that beeped or alarmed too much was the first thing people would smash.
Maybe it's just an "Everything's OK" alarm
heheh ferret was unimpressed with such science 8P
i enjoyed it thouralugy, just alot of good greifs n snap crackel pops to the wrong type of joints
soooo need that SPAM shirt lol hhehahh
Does the one cat have a RFiD tag in his neck?
They both have microchips. Donny just seems to reflect more "stuff" than Fluff for some reason.
Is Donnie chipped?
They're both chipped, I figure Donny has more static cling or something :-P
Ish?
I heard ish.
I've lived in Minnesota I know my ish.
Does your cat have a chip?
RFID might just be doing the trick!
Both cats have chips, but Donny is apparently more filled with static / ghosts.
Is the one cat microchipped and the other one not?
Both are chipped, I guess Donny just has more static cling 😂
Is one cat microchipped and the other one not?
They both have chips.
@@saveitforparts Then perhaps the cats have chips in different locations. RFID chips should be detectable with your meter.
FM has a constant carrier, am doesnt
Donny has a chip. It's rfid so the meter is activating it.
They both have chips, the meter shouldn't be transmitting anything unless it's broken!
📺💬 You need to turn on RF device to have potential differences, and AM frequency has the property that it needs to have some lambda length to detect.
🐐💬 That is correct but some frequency is reflected by wave property, some radios build AM as FM. It is called AM as FM mode which is for internal building.
🐑💬 The AM and FM are different but FM station is based, the repeater or power station works as a based station that allowed them to perform FM with encryption but G.E it had both transmissions for nearby station mode.
🧸💬 Training radio needs to work inside based 👧💬 Anything antenna
📺💬 Anybody still use CB⁉ 🧸💬 That is my can telephone we do not shouting for call brother come out have a breakfast.
0:22 (in Trump's voice) CHINA. 🤣🤣
It's more like "shy-na" when he says it - he doesn't enunciate well at all for some reason or other - probably those bone spurs...
Oh come on that video was to spike your UA-cam ratings (everybody likes cats unless they're dog folk) and an excuse to make a faraday cage.
Good video. I will say that you missed two opportunities. 1. There is a principle in writing called Chekhov's gun. Basically it says that if an element appears in a story it MUST be used later. It there is a gun it will be fired at some point. You parked the EM meter right in front of Chekhov's blender and did not turn it on. 2. Can't you just rename one of the cats Faraday? It's not as if they answer to their Slave Names anyway....
2 in a row? I mean I get that this is a radio, so it's kinda right for the channel, but please don't turn into a review channel.
Conspiracy Theorists are unrelaiable?!
That's what I heard, but it could be a conspiracy 😉
Your catio wasn't *designed* to be a faraday cage --- the mesh is too large, and you probably made no effort to electrically bond all the walls and ground them. So, it likely attenuated the incoming RF somewhat, but not enough to take it below the "Danger! Will Robinson! Danger!" threshold of these things. I think a lot of these EMF meters are off into the "Smoke And Mirrors" end of instrumentation. Measuring the e-Field directly is, as far as I know, impossible. So, you measure voltage potential with a very-high-impedance voltmeter instead--and that's likely what the e-Field measurement section of that device does. For the magnetic field, probably a cheap hall-effect sensor.
Right, the catio wasn't designed that way, but it does have two sizes of mesh (metal fence plus aluminum window screen), and is actually grounded (metal spikes to hold it in place, that are touching the fence and screen). The house is also kind of a faraday cage since it's full of rebar and metal mesh inside the stucco, but there's enough gap where the catio sits against the house to let radio waves sneak through.
Why don't you get a better device to connect to them satellites Why not Because of the battery problems you're having
Will the static electricity setting detect lightning storms approaching?
I'm not sure, I know there are circuits you can build to detect the RF emitted by lightning strikes, and you can buy a sensor for arduino / raspberry pi that detects them.
