In this video we will be having a look at one of the worst fake electronics project videos I have ever seen. Now the original video itself is "well" faked, but the project itself comes with so many mistakes and things that do not make any sense, it is kind of embarrassing. So sit back and let me show you why this laser diode display project will never work and whether we can make it real ;-) Let's get started!

Thanks Scott for putting effort into it and debunking the creator . It's going to help so many people .
I hope so
I doubt it. People don't generally go looking for debunking, they just believe what they want to believe. The video is good for us to watch but the people likely to be taken in by the original video won't come here.
@@John_Ridley exactly. Most visible chat thread is sayings its fake. You believing the worst in people is a shame...
@@greatscottlab Being an Indian and knowing you and Mehdi has been the best gift an electronics enthusiast can receive, but fake Indian TH-camrs like Robotics Kanti are just there to ruin everything.
@@Marin3r101 ...but realistic.
The shift from cheery "it really works" to "no it doesnt" is majestic
Haha ;-)
You.. you are Heisenberg...
jesus fucking christ i hate youtube so much. i block these retarded bots and it still shows the comments
how is it that where ever i go i see your face?
@@makebreak35 He is the one who comments
Thank you Scott for debunking the creator
As an Indian I have been recommended this channel by TH-cam algorithm and I have been astonished by the level of projects on this channel
In future we would appreciate if you continue such efforts so that young enthusiasts couldn't get misleaded
Will do :-)
we should make the Indian debunking association
And there are some fantastic Indian chs out there. I'm subscribed to a few!
@@MCsCreations we gather all of them and start a battle against the frauds
@@big_o1952 That's an excellent idea!
"And making it real". I'm glad I jumped streight to the end of the video and wasn't as disappointed as I would be watching the whole thing
VERYY thanks for debunking that channel
As an Indian it quite bugged me cause that channel's videos were fake and clickbait but but people still liked his videos even after correcting in the comments
Glad to help :-)
I have observed it long ago, I reported few of his videos too, can easily see how fake they are...Hate it when people are misled just for views especially with educational videos.
@@pv7523 I have also observed him , even his ideas aren't real .....
its really annoying when u see fake vids on youtube just for money
Yeah, its very very click bait
De-bunking!
If you make a real version of a fake thing, is it called "re-bunking?"
Soijak lil
Be-dunking on de-bunking
I should have known there would be time travelers on a channel called "Great Scott"
How did you publish this comment 8d ago?
Hey, if you're ever willing to revisit this project, try using a mirror to redirect the light rather than moving the whole laser. The mirror will be lightweight enough that you can use less chunky electromagnets and inertia will be less of a problem. IIRC, this is roughly the same concept real laser displays use.
I also would say that for this specific design you may have more luck trying out a laser diode encased in plastic- I have one lying around and while it is rather dim (I think I might've partially broken it) it is super light compared to a bigger one encased in metal.
That brings up another point. Laser diodes are packaged inside copper or brass cylinders, so that they can be mounted inside brass or copper mounts that are mounted mounted onto aluminum optical plates. The whole assembly is a heat sink to keep the laser diodes from overheating, which reduces resistance, increases current, which causes a runaway state of self destruction.
thats called a Dual Galvanometer Laser. Its what people use when they want this to work
@@RobertFletcherOBE ... aka x/y scanning head, aka diode laser projector. 😎
@@TheOleHermit Wouldn't that mean the laser diode had to constantly cool off in order for that runaway to happen?
I'm assuming that it would be fine at ambient temperatures, so even if it stayed there, it wouldn't enter that state.
@@snjert8406 I believe that you mean to ask,"... constantly cool off in order for that runaway NOT to happen? " Depends upon the output power of the LD & whether it is being driven @ constant TTL 5VDC, PWM, or analogue 0-5V p-p.
Most commercial RGB projectors have finned heatsinks, with cooling fans.
Those above ~4 watts also use temperature controlled Peltier TEC (Thermal Electric Cooling), with sealed optical modules to avoid condensation. 😎
Nothing is more frustrating than following a TH-cam DIY project step after step and ending without expected results,... A lot of fakes out there. Big thanks Scott
Why do they do that?
Sound like alot of effort for nothing.
@@Nobody-il6mq They make money through those affiliate links for components in their fake projects,...
@@Nobody-il6mq They're content farms. The lifehacks/crafts and cooking ones are the most widespread.
@@Nobody-il6mq money
I learned that it's not as simple as it looks! Also, when I've seen laser displays in the past they have used a mirror on a gimbal with the laser being static. The mirror on the gimbal doesn't take nearly as much magnetic force to move as trying to move the whole diode does.
We use x and y scanners
@@martink9785 You must be old school, like me. Nowadays, they're called galvanometers, aka galvos. But, of course you already knew that, lol!
BR 😎
@@TheOleHermit 31 years as a professional laserist, definitely old school 👍 Technically galvanometers with feedback circuits. Even the manufacturers call them scanners. Way back when they were moving coil and torsion bar. Then along came moving magnets with no bar, giving much better performance
@@martink9785 Yes, my 1st scanners were Laserium's open loop GS124's, in 1988, at the London Planetarium, prior to the GS120PD's in my own projectors. I've been known to break a few torsion bars, back in those days.
Now retired, returning to my love of cycloids, and finishing my 3rd build with a pair of C506 galvos (wanted Saturn 5's 😭), upgraded from DT-40's, upgraded from el cheapos from ebay.
Currently developing my own MIDI controlled Teensy ADC/T4 Laser Synth/DAC. Finalizing the PCB in Kicad, soon to be announced and shared on PLF. 🤗
@@TheOleHermit excellent mate 😁 the 506 are definitely better than Chinese. I'm also a fan of the analogue, if I could afford it, I'd start building up some eurorack oscillators etc to play with. Everything now is Pangolin, output quality isn't what it was.
i already commented in his videos that he always make fek videos, now it is proven by our great scott, thanks
I am glad to debunk his creation.
@@greatscottlab also he makes super fek thumbnails in all of his videos
Xavier, i see many comments on social media with this name are you a group of people working together or its a community of people

The easiest laser projector is made with a small mirror and two speakers for X and Y axis. It's not fast enough for oscilloscope-music, but you can draw easy things like circles, squares etc.
Have you ever tried this? I always thought it would work, but after the video I'm not sure anymore, because I would like to recreate it myself
@@MarcelSchr With speakers? Yes I have and it works great. It's a fun little project.
Some day I will build a projector with two mirrors, like a real one. I found someone on the internet using the small stepper motors from CD or floppy drives. Never tried it, but seems very promising.
Would be cool to draw some pictures on the clouds with a strong laser. 😊
Even easier laser projection display idea with no moving parts!
How about an electron gun (laser) inside a vacuum tube with magnetic fields focusing and bending the rays (changing the trajectory of the electronics) to hit specific points on a phosphorescent coating on the interior side of the tube opposite to the electron emitter with the target point moving across in a line and then up line by line to display an image on the outside of the tube.
Oh wait that's a CRT (Cathode Ray Tube) display, first conceived around 130 years ago.
@@somehow6839 Even easier? Then show me how to "easily" build a CRT with a bit of scrap glued to a piece of wood.
But everybody can move a little mirror in two directions and point a laser at it, all with old stuff most electronic hobbyists have laying around. And you can't really compare a CRT to a projector.
Now I get some flashbacks. 30 years ago my buddy and I did exactly that. He had a helium-neon-laser (it had the size of a little brief case) and we glued one side of a tiny laser mirror to the middle of a little speaker (we cut off the membran for faster movement) and the other side at a hinge that was made of a thin plastic tube and a peace of wire. We made two of them and we could create some nice figures using two sinus generators.
We were teenagers, btw :)
There's an old school version that's actually sound reactive in the most analog of ways where you take a laser pointer and point it at a small mirror attached to a Bloon stretched across a ring so that when sound vibrations hit the stretched Bloon it vibrates the mirror, changing the angle of reflection of the laser point.
That sounds real :-)
the "real" way to project a laser with a galvanometer is not far off from this
You can also modify an old speaker for the active version of this.
This is amazing
@@johnathanmcdoe connecting diafragms with a wire or rod into the diode might be more efficient than a magnet.
Iv tried reporting his videos hundreds of times. TH-cam just doesn't do anything. It is similar to the case of how mark rober debunked the fake drone video. It can totally crush the confidence of a budding electronics enthusiast
Great work! You know you’re maturing when you decide that developing something fun wouldn’t be worth it. Thanks for your effort.
It makes more sense to suspend a very lightweight mirror and deflect that with smaller magnets. It'll still be clunky, but better than the original idea. You can get an infinity symbol by putting plastic wrap over a loudspeaker, gluing a small mirror in the middle of the plastic, bouncing a laser off the mirror from 45 degrees, while feeding variable frequencies from a function generator to the loudspeaker. Certain harmonics of the mirror's resonant frequency will generate shapes whose size varies with the harmonic value.
I love that the video image of the fake device working on the other channel used a flashing image on the paper rather than one that traces out the shape. It's all on or all off in a way that a vector laser image would not be.
In my highschool years they had a laser display demonstration once. But the method they used was different. Instead of manipulating the diode itself, they bounced the beam off of mirrors mounted on speakers. Much simpler to make, much better control. Just play the right waveforms...
Yep. Servos and mirrors are the solution.
I did exactly that in the early '90-s as a light show for a school band that I was helping out. To get a grip on how long ago it was, I used the physics institution's He-Ne-laser. A program I made on my Amiga created the waveforms. And since I didn't want to take my computer to school, I recorded them on a Hi-fi VHS deck so they could be played back with enough fidelity for the figures not to get distorted. Compact cassette or even reel-to-reel wasn't even close to acceptable.
When people make scams like this, please NEVER give them links. Watching their videos even to criticise them makes them money
Thank you for all the work you put into this. The difference between people who are easily led and people who actually know something.
That's why your channel is good. I watched the entire video about a fake electronic project, knowing that it wouldn't work, but I still watched it 😅
I know there is one guy something like "robotics kanti" his projects (including this one) are all like this, a mix of reality and video editions. It is very sad to see people liking the video and venerating this guy as if he was awesome engineer. Thanks for this channel for showing things with scientific background.
Glad I could help.
Sometime TH-cam algorithm gets it right. Just like you can't see a forest if you focus on a tree, it's easy to forget how big (and diverse/weird) TH-cam is if you focus on the videos you subscribe to. I'm thankful I have you in my list, because I enables me to not even be aware that the lier's channel even existed.
Glad I could help :-)
it would be much easier to have a stationary laser that's rigidly mounted to a set of actuators, and aim it at a spinning mirror that is canted to an angle. This would give a better result, as the mirror works as a "shutter" of sorts, and the laser focal point is always the same, and the laser only has to move very very minute distances...
We need more people like you to keep the trend going on busting the liars and cheaters of the world out. Good job!
Neat idea!
If you want cheap 'n' dirty shapes with a laser pointer you can always do that 'mirror on a membrane vibrated by sound' project - I had fun making circles and squares and lemniscates with different tones.
I made something like that once, but it moved a little mirror instead of the diode itself. the coil was much smaller and closer, but with a high enough PWM frequency the point stayed a point and could been moved fast enough for simple forms.
this is a good one, please video more of this debunk videos! there are so many fakes on Tiktok, Insta, TH-cam
as an Indian and an ECE student I thank you very much for exposing him.
also please review his recent video on mobile signal jammer.
its a humble request, please
If he's got a decent antenna and enough amplification, then a signal jammer should be fairly easy. It's one of the easiest circuits to do, since you just need a wide enough frequency range at a high enough power at the receiver to render the signal unintelligible to the receiver. If he can't do that, then he should switch to interior decoration.
Seems like a lot more trouble than just using two front surface mirrors and making a galvanometer from a couple of old speakers or just winding your own. That's how we did it back in the 70s, though back then we had to use gas discharge lasers from surplus electronics suppliers.
Have seen similar approach in resin 3d printers from formlabs.
About 30 years ago I made something similar to this (that worked!). Difference was I directed the laser beam, not the who damn laser head (since.. you know... mass of photons vs metal - ha ha!). I had an old video laser disc player laying around that I robbed for parts. It used a red HeNe laser tube (pretty cool looking) and a couple of mirrors that controlled the beam. 1 for X & 1 for Y axis. I was just using what I had laying around - and this was way before Arduinos and the internet existed - so all I used was a stereo audio source. One channel connected to each axis.
Certain music would give boring patterns, but Pink Floyd (for one) was awesome since they used such crazy mixing of the left & right channels. The laser was SO bright, I could shoot a pattern at my ceiling and get an 8- 10ft diameter pattern. I still have it, but haven't powered it up in at least 20 years. No clue if it still works even. I'll have to try it one day!
Make a video, maybe GreatScott, can you feature it?
@@juniordouw6681 - I'll dig it out, dust it off, see if it still works. If the lasers toast I'll have to do a massive downgrade to a diode laser though. No idea where I would ever find another HeNe. The player was from (the late 80's early 90's?!).
@@DrFiero it sounds really cool tho. Some very nice "toy" haha
@@DrFiero : You should be able to find a comparable (or even massively more powerful) laser diode, since they would have needed about the same power for CDs as for LaserDisc. Even better, you could always get a prism to route several colors of laser diode together, and have the brightness of each controlled by one of those frequency-to-color circuits that (I think) RadioShack used to sell (one frequency range each for red, blue, and green, controlling the brightness of each according to amplitude). All the usual laser & bright-light cautions apply!
That's why in commercial products they use mirrors to draw images with laser :D. Great work Scott!
This really helps for small project makers who are new to the world of electronics. This kind of video will help them to understand the reality.
I wish you upload more videos related to debunking 😊
Good to see this type of video. We want more people feeling confident about learning electronics. All fake projects do is discourage those trying to learn. Thanks. Greets from Florida, USA. Cheers
This. I get mad at youtube shorts that show some clickbait project, but to go even further and provide non-working project writeups that people actually will try to recreate is just evil. Hope that karma is real and gives that "creator" what they deserve.
My first thought when I saw the picture on Patreon was, are you making some kind of electric motor.
I could not be more wrong. Great video thou, debunking stuff like a true David L. Jones (eevblog) debunk video. 😂
Another great video Scott. I appreciate the effort you went into in order to debunk another fake. It's startling how many people viewed that video and subscribe to that TH-camr. Thank you for your efforts to set people straight.
Wow I remember when you had a handful of subscribers, 1.8m??? I’m so happy for you!! That’s incredible!! You deserve all the success!! I’ve learned sooo much from you
It's really shocking for me , as both the creators are one of my favourites but thanks scott for Revealing the truth for our good!
Love your work! Keep it up!
Thanks mate :-) Will do
Kanti is blissfully unaware that he had been holding your beer while you made this video.
Always love how informative your videos are keep up the wonderful work
Also you need gate resistors. To save outputs of your Arduino.
Not for every Mosfet, the series that where shown are made for digital input by an arduino for example. I run pwm powered LEDs with them on an espXx module.
@@matneu27 It's not about the logical threshold of the mosfet.
Do you know what a capacitive load is? Which currents are produced by switching? Is it safe enough for arduino outputs?
These transistors have an input capacitance of about 1.5 nF.
That is, Arduino outputs with their maximum peak current of 40 mA can get into trouble.
@@matneu27 The fact that connecting the arduino outputs directly to the gates of these transistors worked for you does not mean that it will work for everyone. Perhaps your connection was made with long thin wires (which worked like resistors, in fact). And if you make the same connection with a normal conductor on the printed circuit board, then the arduino will fail very quickly.
The body diodes of the MOSFETs would tend to absorb much of the inductive spike, but you're right, a parallel flyback diode is safer. You might get better performance by attaching a magnet to the diode, making an iron circuit between the coils so the laser diode lives in the gap, fine tuning the gap size, adjusting the compliance of the laser diode mount, etc., but the best you're going to get out of it is fairly low frequency Lissajous figures, nothing like a raster scan.
I don't have any experience with these types of systems but that was my first thought. You'll never be able to control the magnetic field and movement fast enough to complete an 'image frame' regardless of what you do. Maybe if you scale it and add multiple projecting units to complete one section of a frame, or create a grid system similar to pixels, but the thing itself would be very slow. There's no way this 'solution' has any ground to stand on.
@@Adrian2140 it can be done but you need precise placement of the coils and the laser source plus feedback
@@viermidebutura precise placement of the coils is expected, but I highly doubt you can go from one opposing side to the other in a physical environment controlled by magnetic fields in a timely manner to actually make a frame. The reason this works in an old cathode ray tubes is because projection is done and controlled by refocusing the electron beam itself via coils, not the whole gun. That's not how lasers work.
@@Adrian2140 the problem with a mechanical approach is the spring that holds the laser diode which will vibrate like crazy.
This vibration can be harnessed but you overcomplicate the driving circuit.
The deflection coils on a CRT have nothing to do with focusing but they move the electron beam across the screen
@@viermidebutura That's what I meant by focus, as in direct the beam. You can't mechanically reproduce what the coils do with an electron beam in a cathode ray tube.
The only way this would work would be by redirecting the laser in a similar manner, not the laser source itself, but since you can't do that with lasers, you'd need a 'filter' or lense that redirects it.
That's why I said this idea has no ground to stand on from the start, just like GS pointed out.
I'm so glad you made this video about the fake information that channel uploads. This will help viewers identify legitimate content.
Thank you Scott for pointing out a fake TH-camr who should in all sincerity be banned from creating any content after all. Cheers and keep up the good work!
it would be dope if someone continues this project and adds the feedback system and makes a crude display out of it
Well someone already has, over 100 years ago, it's called a CRT Cathode Ray tube, used in the old big fat tvs.
@@somehow6839 well ik duh, and crts dont use lasers iirc \s
@@somehow6839 : CRTs aren't laser displays, laser displays aren't CRTs.
@@somehow6839 moving physical laser that fast so it draws image not gonna work that's why the electron beam is perfect for this task
To achieve the fidelity of the display in the original creator's project, a high-speed DAC would've been required to control the laser. And mechanical effects cannot be ignored when vibrating the diode at such high speeds. It could draw oscilloscope figures, but not much.
Im glad you didnt just say it doesnt work but also showed why. Big ups for also showing how to build a better one.
I posted a comment on that scam video with a link to this debunking video. Added some of my observations as well. Hope what you did manage to at least prevent more people from getting scammed. Thank you for contributing to make youtube a better place!
Best electric engineer in TH-cam i really learn a lot Frome u hope u all the best
And I hope some day I became like great Scott 😁
Scott
Thanks :-)
So basically this is the electronics version of those stupid "survival construction" videos where they pretend to build mansions using nothing but a stick.
I can see that without even seeing the videos, already added them to do not recommend list
Great video
So time consuming to de-bunk other YT trends, with no connection to reality.
Great job 👍
Thanks for sharing your experience with all of us 👍😀
Thank you for putting effort and identifying fake projects
Love it! More of these videos if you can!
Sure ;-)
Thank you for debunking and debuggin and de.... building? :D
You are welcome😁
This was the Video i was wating for a long time,
Thanks alot for exposing the Truth.
iam a small youtuber, and Our Great Scott is a Best Teacher 👍✌️
Thanks mate :-)
Ibsaw his videos as well I had a feeling a lot of his projects were not correct, thanks for actually trying to make them
Thanks for debunking this. Sometimes his project seem questionable. I sometimes stumbled on alot of not compaling codes. You should really make more of these were you debunk fake projects. Especially seemingly "real" unbelievable ones. Also, like all his video have unrealistic clickbait that I simply question the legitimacy of his videos with out going further. I am a small content creator, i know it's hard to attract people to your chanel, but at least do it without trapping people.
Hii
@@Purple431 you watch him too ? Great ! I mean he is a really great content creator (Scott). I especially like his approach in this video.
Cool Video! Please debunk more fake projects! :D
Will do when they real annoy me ;-)
Very nice breakdown on both the initial design and the concept itself.
I've seen something adjacent to this, where instead of magnets affecting the diode, they actually use a mirror and a speaker to control the laser output shape with sound. Theoretically, that would be a much simpler way to get the same end result.
When you said "NO! It doesn't", I felt you channel a little of your inner ElectroBoom lmao
The total lack of iron cores were an instant red flag.
This should be a series on your channel called 'Electronics content cop' 😂
Great video Scott, Thanks for sharing.
Great video! Can you make a follow-up on how its done on real laser projectors? Those micro mirror actuators are really intriguing :)
Mehdi is Batman, and Scott is Robin.
The rectifier duo!
Really appreciate your efforts. I have gone through his channel and most of projects are fake or poor working
"way to much effort for something that isn't really usefull " - recalling the Transformer Speaker video from the past xD
Really Great reveal Scott, please continue the series......
Will try to do so :-)
Loved the video👏but how do Varistors work? GreatScott
That schematic really gave me some laughs. I noticed the n channels were being used to switch high side, but the fact that the body diodes were forward biased was even funnier.
I love it when someone with the real brain power shoots down these hoaxes! Thanks for your efforts...
I really think that this type of videos become rather important for enthousiasts. (Probably depends on my and your algorithm), but the more I click on "do not recommend this channel", the more videos about free energy etc. Appear. Luckily, there is a frequent stream of GreatScott uploads. Thanks again for all the information.
Old TV Screens used a similar technology where they made the beam and then use magnetic fields to bend the beam until it hits the correct part of the screen. Which I find amazing.
Super analysis bro video is just amazing
Keep it up 👍👍
Thanks for your diligent effort to push back against junk information/lies
I just went to check the original video... comments are off and the very first line of subtitles says "Special Thanks to GreatScott for promoting this video" xD
Love how you can see in the fake video how there's flickering in the whole area where the figure is casted almost like it's taken from a darker background made transparent to look like it's on the paper, and repeatedly spread in intervals across the timeline to create the illusion of light delay
Very cool debunk! I would think developing a feedback system would be probably the hardest part of this. Just as a thought experiment, would you start by throwing a hall effect sensor on each of the electromagnets then trying to correlate those values to the laser displacement?
This just reminds me of the amazing maker scam a few years back. A shame some people resorts to fake scams and not using their talents for something useful.
That’s one way to bring an idea to life. Fake it so as to piss off a bench-grunt to build it out of spite!
I love that you debunked a fake project, always nice to see! If you choose to go further into this/other laser projects I am down to help out!
That’s a serious troll post whoever started this impossible project. Thanks for debunking it. That’s a Great video Scott!!!!
Parabéns!! Muito bom o conteúdo de vocês. 👏🏽👏🏽👏🏽
It's definitely better to build the dual mirror galvo setup. That's what is used in most commercial laser projections. This way with magnets like this, is never going to display with much accuracy. I have seen that video and I thought it looked fake so glad to see someone else prove it.
The first photo on the blog post you linked to reveals it's a fake. It's a red laser diode, yet the display shows red, black, and white. How did the red laser produce white output?
Thanks for digging into it and sharing your findings! I have a new appreciation for how well mirrors on galvanometers work for directing laser beams.
Those flexible PCB's that was your sponsor has me interested. Could be great for drone applications, being so lightweight and flexible.
I have an idea from a video where fast rotating mirrors are used to capture fast moving objects in slow mo, such as ping pong balls and tank shels. You can have the laser fixed, and make 2 mirrors rotating in 2 different axis.
Felt like a “Electronic’s must be respected”, Walter White mood ahahah.
Very nice and interesting video :)
thank you, i was trying to make a laser turret to shoot down bugs. in addition to frame servos, i needed something additional for the laser head. This is exactly what im looking for
Good stuff. Go hard on scammers like this! They hurt us all!
Robotics Kanti video:
This video isn't available anymore
Great work👍
Cheers to your health from Canada
Damn an expose, DIY and epic voice? all at once? glad i found this!
;-)
Great video i noticed i have the same msi laptop and onshape cad. The laser proyecting method seemed familiar to me because it reminded me of how crt monitors worked
I tried remaking multiple projects on Robotics Kanti's channel, and I regretted it as none of them worked. This channel is full of fake projects and clickbait videos. But GreatScott's channel is great though, I like every project made on it and I'm watching it for years, and everything here is real and to be trusted. Thanks, Scott.
seeing the potential and creating a working prototype. priceless ;)
From an engineering standpoint it's rather simple: like an electron tube, just way way worse
I ran into the same issue when working on a client project. I ended up having to figure out how to actually make it work for my client's video. In the end, we got something that looked way cooler and actually worked.
There is something oddly satisfying about seeing fake/scam content creators get called out.
I don’t have too much hands-on experience so if I saw that guy’s circuit without seeing this video, I probably would’ve believed it XD
