Nice free learning
why is this coommer=nt from 9 days ago
Great Scott Sir, there is a another channel name ET DISCOVER has made a signal jammer and signal booster, so sir i kindly request🙏🏻🙏🏻 you to investigate on his video also sir.
Thank you for exposing this idiocy !!
Dave from EEVBlog exposes them too, so you're in good company 👍
If there is an electronic component that is common across the videos, then they might be scamming people to empty out excess of junk they have in their stores by making the videos.
expose more of these channels that show fake and misinformative content. Thanks a lot for your work
Will do :-) Thanks
Yes, that's great - expose them as much as you can. I acutally don't really care, if some people "steal money" from a greedy company like google (who has ruined CZcams, compared to what it once was, anyway), by getting payed for views, that would otherwise not be there (because that's what all is about. There are probably very few people who put up fake content, just for fun. At least not electronics - political content could be a different story though. It's pretty much all about geting an easy way to make money).
But, it has gotten to a level where it indirectly becomes a problem foreveryone - especially beginers (who try to build shit that doesn't work and often think they do something wrong them self and because of that wastes a lot of time). Like 50% of CZcams content is fake nowadays.
Roasting fake clickbaits is always welcome
@@greatscottlab
Please do it, guys like you and me, see whats wrong, but someone who is somewhat new to elektronics, may go to the trouble sourcing maybe obsolete parts to find out that this circuit is a ton of wasted time, material and money!
Scott, keep that educational Videos cumming!
Yeah, just like ElectoBoom with the so called "free energy" videos
Sad thing it's nearly always the fakes and spam that get millions of views while the genuinely helpful and inspirational get nothing in comparison.
I would not say nothing. But it definitely sucks seeing fake circuits get so popular.
@@greatscottlabbecause of one thing they make what audience wants that’s why 555 is very popular in those schematics because 555 is well known and most people would think okay this might work
@@greatscottlab They get this popular because 99 percent of that audience have zero clue how to make one and just go "oooh, science!".
They know it is fake, but that is just their business model. Attract millions of views to get the channel monetized.
Its similar to losing weight. Noone likes to eat healthy and excercise, they rather spend money on well produced nonsense. The truth is out there, if you’re willing to listen.
the rectifi-
wait, wrong channel 😂
kiddin aside, love your videos!
Haha thanks :-) We should all rectify a bit ;-)
...not your puny single diode rectifier!
The fool breedge Rectifiyah!
Even the design of an antenna for this purpose is a science for its own.
True
Some people make thesis about antenna design for these frequencies 😀 and in these videos the dude just coils wire...
@@user-kr8tp3ko8zI mean to be fair at those frequencies a little bit of coiled wire (of the correct length of course) would generally suffice. Receiving 1090mhz ADS-B from aeroplanes only needs about a 6.5cm dipole antenna (so about 13cm total).
EDIT Which is exactly what I have attached to my window, furthest plane I've picked up so far with full location data being 381km away
@@irreverend_ That is a genuinely intriguing idea...
I don't need another hobby. I don't need another hobby. I don't need another hobby...
Oh, dear :(
@@user-kr8tp3ko8z That "just coils wire" is called a helical antenna and perfectly legit for GSM applications. There are dual band and even quad band designs out there. People might write a thesis about novel antenna designs, but this isn't novel. People also cover pain management in their thesis, yet you're able to simply take an Ibruprofen against headache despite lacking a medical degree. It's really not that deep 🙂
"He who knows nothing must believe everything"
But now we know, thanks! 👍
Ah, but what of "The only thing I know is that I know nothing."

Socrates: Then you're a student. 😉
Oi! I resemble that remark!
And knowing is half the battle!
You are doing a great service by debunking their disservice. I started with electronics when I was 14 (over 40 years ago) and though it is not my occupation I still play around with it as a hobby. What those channels are doing is beyond dishonest because they not only present BS as facts but also discourage people who want to learn. They will try and make one of those circuits work when it doesn't they won't be able to understand why which may frustrate them to the point of giving up. So, yes, keep fighting the good fight :)
If people who build jammers get frustrated and give up, good. But they're welcome to learn how to build non-interfering transmitters that should be well documented.
@@lunalangton5776 Of course, I meant as electronics projects in general, not this case in special.
@@adilsongoliveira Yep, would love to see more mistakes pointed out in circuits, where that would serve as a good learning example.
Probably a good thing that all the people trying to build circuits designed to cause mayhem are distracted by these designs that don't actually work.
Too bad they're also scamming people trying to build a booster.
Yeah I never really thought about it in that way, good point!
Seeing the real trasmitter device Scott showed here and said that this level is basically black mag now, people cannot make jammer devices at home, too many specific components are needed with high quality circuit assembeling.
Maybe it's a systemic misinformation campaign! :D
They are the script kiddies of the RF world
Definitely expose them! I hate these channels that use false information and even AI, combined with click baity titles to get views. This type of content just serves to clutter up the internet and discourage novices that might try to build the circuits and just blame themselves when it doesn't work.
While it's obvious that circuits like these can't work at radio frequencies, it should be noted that the capacitive load of a passive scope probe will affect the circuit and most common oscilloscopes can't measure such high frequencies anyway.
They in fact can with the right set up.
It's a good thing the power output is low. Interference around 125MHz is gonna piss off two regulatory authorities simultaneously. Aviation and communications!
I stopped believing that it could possibly work when I saw through hole components for GHz frequencies, but thanks for going all the way, very entertaining...
Absolutely right!! We can’t block or boost mobile RF signal by simply these things. The mobile RF system use complex modulation technique such as OFDMA and transmission technique such as MIMO will make them more immune to external interferences. The frequency hopping spread spectrum technique will spread the signal over a wide frequency range, making it more resistant to interference and noise. Modern mobile communication systems employ sophisticated error detection and correction algorithms, such as Forward Error Correction (FEC) and Automatic Repeat request (ARQ). These techniques detect errors in the received data and correct them automatically. It also adapt to changing conditions by adjusting parameters like transmission power, modulation schemes, frequency band and data rates based on environmental conditions. From these observations it is very clear that mobile jamming / boosting is not a simple task. It requires more specialized RF IC and well-designed antenna systems along with complex signal processing algorithms.
FHSS isn't used on LTE/5G and if there only is 900 MHz GSM/LTE available, a simple single band jammer would technically be enough. However, often times you have all sorts of bands available.
Industry standard for boosting are Cel-Fi GO units.
RF jamming is EXTREMELY simple, so simple in fact it is possible to do it accidentally, all you have to do is (metaphorically) scream louder than the nearest tower on all the frequencies you want to block. What isn't simple is SELECTIVELY jamming ONLY mobile phone signals and doing it in a way that doesn't end up with you destroying your device while a representative of the FCC (or your local equivalent) observes you.
plus 1 for more exposure of this fake electronics. These "creators" are giving electronics a bad reputation while at the same time making a living off the click-bait they are creating. There is too much like this on youtube...
Expose more of this crap. Some people think they can tell you anything, so it is good to expose them. And on the other side, its also educative... We all learn from those "mistakes". Thank you Scott!
I mean they are just everywhere, fake channels, it sucks seeing that majority of the content is this way
We are lucky we have guys like you that give out real knowledge 🙌
I designed television front end for several TV manufaturers years ago. You are 100% correct, keep exposing the frauds.
Please continue, it will be great to have a reputable CZcams channel debunking all the fake videos on CZcams.
Expose them all. Also it's interesting to find out what these scam circuits even do in the first place and the flaws in them.
Top video. Expose the predatory bastards! Make it the mainstay of your channel. The community needs it.
Debunk them all to hell! You're doing a great job here. For Science!
please protect people from wasting electronic components. every built up circuit is just ewaste
Nobody built that. The people who would be able to, saw the 555 and knew it was fake. The folks who don't know, can't follow schematics.
@@unhandled12345 i would disagree. i guess many people out there are able to build up a circuit from a schematic perfectly , but do not understand what exactly they built there. Me as a kid would be a good example. With 13/14 years i was definetly able to build up a schematic, but do not understand it.
Let them practise and troubleshoot problem
We need more people who are willing to expose channels who misinform others. Keep up the good work.
yeah, normally most phone jammers are scams because they use 5-5-5 timers to try jamming a 2.4 - 5 Ghz signal 🤣🤣🤣🤣
😂😂
Please ‘seek out and destroy’ the false claims!
BE our ‘HUNTER KILLER’ …
Find us projects worth our ‘valuable time’
I took engineering in the field of electrical and electronics because of Greatscott, electroboom, plasma channel , now i am graduated , time flies fast!!!
I'm down with debunking some more of these circuits, or even the opposite, proving some of them useful. A regular series of "Two of these designs are junk, but the third actually works. Can you guess which one" could actually be a good deal of fun.
Lovely idea. Not sure how easy it will be to actually do. But I put it on my to do list.
Thank you so much for exposing the fake electronic circuit in your video. Your thorough research and clear explanation are invaluable. Please keep making more videos like this.
it's incredibly helpful for the community!
Yes...carry on exposing....I don't want to waste my time building rubbish
On internet " Everything that glitters is not gold.." and "Nobody knows that you are a dog "
I think it's a good thing that you debunk such videos. Nowadays CZcams is full of such videos that are actually just a scam. Great work and I'd love to see more of these debunking videos.
Great explanations man. TY for taking the time to break it all down
I like the debunking videos. Sadly, there are so many hucksters on CZcams creating confusion for students who are trying to learn on their own path.
The most amazing thing in this video is that your phone can switch between the different networks.
Great video ! it's always amazing to see the explanation and research you do to expose those videos with precision. We get to learn something too and i totally think you should do more videos like this.
Expose them. These people are making money by promoting fake products.
Tell you a truth your channel is really the best. I have never seen any informative channel like yours.❤ but it's under rated because some people think your videos are hard to understand😂. But i love your videos a lot.
Honestly Scott I love your DIY or BUY series and this has that same feel, but is a bit more informative. It was a great video and I look forward to seeing more.
This is a great video! Honestly, I forgot about your channel for a while, but that's to this video I'm interested again. Like fresh air!
YES please, expose as many as you can! Most of them publish any kind of content (mostly fake) just to get traffic and hence, ads revenue and no only that, they also link the "products" they use for making those projects, also receiving commission for the sales of said items. They take advantage of the lack of knowledge of regular people (because it takes someone like you to know it's fake). So thanks a lot and keep it coming! :)
Good job, I hope you do some more videos covering fake claims like this. It damages the whole hobby when ideas like that gain traction.
I agree...expose more of these fake non functional circuits....I enjoy watching your channel because it's educational and full of information...well done and keep up the exelant work
Here before they probably file a fraudulent takedown to hide this expose...
I remember being in an abandoned mine, on a pile of magnetite and having 100% cell phone coverage and being unable to receive data or make a call, it might be better to test transfer data and see if the connection is cut off
Another great video, thank you.
Also, thank you for putting a link to the "Stay Creative" shirts.
These along with fake free energy videos are the worst of the worst.
Your channel and Electroboom are the only ones I follow for electronics insight. Too bad these lame scammers get most of the clicks and views. Keep creating awesome content and I'll keep watching and learning. Thanks for sharing!
wait so everything on the internet is not always true?!?!?! well dang.... nice job breaking this down, expose em all!
The truth is important, because many fraudsters deceive people intentionally or out of ignorance.
Nice work. Such scam artists out there. Would love to see more of this.
YES PLEASE expose more channels the garbge is every where on youtube preventing quality informative content from getting the views and appreciation they deserve.
Thank you for your Hard work and time you put into these quality+ Informative videos and Guides.
I think this fits perfectly for your channel and would definitely watch more videos of this kind. Great reference also when friends claims they found dome super decice 😂
I like your videos and videos like this. The number of views these fake videos get is unbelievable. This shows how easily people can believe anything fake on the internet.
I love the concept ; usually when I see such videos where an involved device is created super simply, I don't have the electronics knowledge to find the flaw. So it is very interesting to hear your explanation as to why it will not work (even more so if it's a huge list of reasons like in this video)
your subtle and professional approach on debunking this nonsensical booster/jammer makes me think that you can do a great job on doing "mythbusters" electronics edition!
Love that you expose them. Keep doing that. 😀
Thanks for the work and cool fake debunk clearly explained !
Expose them, Scott. Otherwise people will think they're actually learning from these fake circuits.
Excellent explanation as usual
Thanks :-)
I enjoyed this video and learned something new. I have been tempted to try that booster circuit because when I go to the park across the street I get diminished reception on my iPhone SE. I thought about putting up a wi-fi extender or mesh to get a better wi-fi signal, but then I would be exposing my LAN for all to see.
It is almost impossible to prevent people from finding schematics of non working electronic devices. But what one can do is not spread schematics or link to them if one has not tested them or does not know whether it is a working design or not. In a forum about electronics I visit on a regular basis we started including comments IN the image of a schematic stating whether a design is TESTED/WORKING or UNTESTED, so that if the schematic is picked up by some search engine (typically the text normally accompanying the schematic is lost), the status of the schematic is clear to the person finding it. This will hopefully help a beginner who can not see for himself whether a circuit makes sense or not to decide whether he wants to spend time and money on it or not.
I applaud this schematic labelling idea. Other sites should do this too.
I really like these kind of videos :) thank you for your work and time.
this was really nicely done 👍👍👍
Greetings from Argentina! Great work stating the pure facts without nonsensical claims and unnecessary statemens while going right down to the point. After being an senior electronics tech, designer and service tech for 33 years, having started very young as a hobbyist and a diyer, i get sick to my stomach every time i see these fake videos pop up in my feeds. Whenever possible I do report them after reviewing their contents... Back in my days i was taught by good old school techs, engineers and also my father who was an electrical engineer with extensive knowledge in industrial and digital electronics... Today we open a video streaming platform and we find this junk!. I try putting myself in the mindset of an electronics hobbyist in his o her first steps into this great trade and hobby and i feel so bad for them and how discouraging their "unknown" failures at building some circuit because of these fake channels with fake impossible-to-work "circuits". They need to be exposed, reported and get them shut down so people who bring good teaching and valid content can get the recognision they deserve. Thanks for your work on your videos as you bring solid content every time.
You should expose more of these videos to inform what is right and what is wrong.... so many fake things here. Thanks for all your many fantastic videos...
You know what, it might actually be kinda based to advertise a "jammer" circuit that doesn't work, and make sure it stays at the top of search results so that it funnels in everyone too stupid to realize it can never actually work. Not this one though. One that's truly harmless.
Nice video can you create a series of videos to expose these gimmicks ....!!!??
We enjoyed this video ❤️
Awesome :-)
Don’t waste your valuable time, help others when you can however keep teaching. That is time well spent. Thank you for your channel. I’ve been a long time subscriber.
Please do more of these, but also get a bit more into the technical side and explain the mistakes and what would be the correct approach (for non illegal circuits of course)!
Thanks for your efforts. Do this type of job we love to see
I believe the quality of the internet depends on the number of BS that is called out. If people are made accountable for their publication they might add a disclaimer or think through with the publication. Great job by great scott 😎😎😎
Well, I'd say go for it! 😊
Thanks a bunch, dude!
Stay safe there with your family! 🖖😊
In the simplest terms... to jam an RF signal you need 3 things to happen; same frequency (spot jamming), same modulation, and over power the signal by at least twice the strength. There is of course a lot more to it but this is the basis
Absolutely please expose more of them :)
Please continue exposing these time wasters
Definitely like the idea of exposing the snake oil proponents, but you could spend all your time on just that! We would miss out on the other great content you provide!
Could you do a video on your parts storage solution and why you organized them the way you did? I like the boxes with dividers, many parts cabinets don't have provisions for those, especially dividers that run from the front to the back of the drawer. If they did, i could keep multiple values of axial components in a single drawer (say 500K ohm and 1M ohm in one drawer instead of two drawers).
Thanks for the great videos and sharing something interesting!
Thank you, your videos are very educational.
It's stuff like this CZcams was made for!
Keep up the good work debunking scams!
I respect u spend time on building the hardware. I m sure u know this wont work fm the very first glance of the schematics. This is fun watching ur hand sketch and ur neat hand script…. This is iconic 🎉
Hey GreatScott! Your videos are 100% informative and always truthful. I have been watching your videos for years now.
Unfortunately channels with fake circuits get millions of views while real educational channels like yours hardly get the exposure they deserve.
While making new exposé videos, i would suggest to add a bit of *drama* so that CZcams algorithm will pick up these videos. I know that has never been your style but in order to survive this algorithm, you will have to give it what it wants :(
Thank you for your thorough explanations.
Glad it was helpful!
Please do more! I ask mostly because it is a chance for you to explain stuff in a practical way, with an example...
Thank you! When I was younger I always used to think somehow the designers of these fake circuits had discovered properties of components that weren't published that let them do really amazing things outside their normal parameters. I was naive. But I was innocent too. Please keep doing videos like this to help keep people learning on the right track.
Love your videos. Love learning about electronics
Awesome :-)
Please expose it more..I really love how you explain all the component in the circuit and why it doesnt function like it state.
holy moly you did the thing at the end :D :DDDDDDD that caught me off guard!
I do remember people using "Signal Boosting Stickers" on their phones during the good old 2G days.
Make this a series, it will definitely be interesting for sure.
In a world where "unlimited free energy" videos where contraptions that use dirty spark plugs, magnets and tons of hot melt glue can create 10+ million views, I am not surprised.
Well done, sir. As I am interested but somewhat inept on electtronics, I fear to easily fall prey to someone like the channe mentioned. So, I am really fine with seein more like this. BTW your hidden gems series is also really cool. Thanks a lot for your work.
you just saved lots of peoples valuable time. thankyou.
It's nice expose those channels
And another tip after exposing and explaining the circuit
You can also recreate that circuit
Love your videos sir
You r like a teacher for me ❤
Mr Great Scott, thanks for the informative video, since you busted fake camera tutorials we need a video to make a board which will help us salvage old smartphone camera sensors
Please keep exposing these fakes and while also showing how to do it correctly.
It might become your personal windmill, but please do more of these videos!
Anakin vs Padme meme vibes right in the beginning! 😂
Start a new channel to Search and Debunk the fraudsters. I can understand that people fall for this s**t, It looks cool and costs them so little. I love your channel, keep it real and SYNT. Thanks for sharing.
How is there comment from 9 days ago although this just came out

@@greatscottlab Du hast auf einen Bot geantwortet. Deshalb das obszöne Profilbild und der kopierte Kommentar mit Link auf dem Profil. Der Originalkommentar (auf den du schon geantwortet hast) hat weniger Likes, da er nicht von den anderen Bots geboosted wurde.
My first impulse was: Yeah, expose more of them. But in the end there will be nothing learned. So finally I think, it’s better to ignore them.
Thank you. Please expose them! Fake science videos does not help. Many of them even dangerous. This makes me mad. If someone replicates sepending money and doing e-waste instead of really learning. This is why I less and less trust in youtube explanation/course videos. Be harsh these are scammers! Thank you.
