Hey, is it possible to become the STL File for a 3D print ? Thanks in advance 😊
Hey, where are the links for the better modules
Maybe you should have corrected measured distance with relative position of sensor to the center of the spinning disk. Anyway, good job.
You could eliminate the slip ring (which will wear out) by rotating a front-surface mirror instead of the sensor. And you don't need a stepper motor. A slow, geared motor powered by a voltage regulator with an optical sensor detecting its position on every revolution would work as well. Cool project. Next do an up/down left/right scanning version that can make a 3D image!
That device is like a 360-version of the popular arduino ultrasonic radar. Great job :)
This is a brilliant project - it covers a range of interesting concepts - sending data through a slip ring, etc.
Dude i must say that you are one of the greatest electronic channel here in youtube, you have so much passion
Thank you!
You put out some of the most interesting projects. Thanks for sharing.
You are discovered the "slip ring for me,
thank you from Kazakhstan :)
Dude, you're doing a great job. Keep doing whatever you're doing. Loves from Turkey

Very well made dude, Thank you for the video.
Thank you man I waiting for this
Amazing unique project! Thank you!
This is really awesome. Thanks for the tutorial.
Great video and tutorial as always
big fan; from Algeria .. Thank you, man, I waiting for this
Excellent video ! Just what I need !
Pretty interesting project, dude! Awesome! 😃
Absolutamente fantástico! Good job!
Very nice project you smart and creative.
Thank you 👍
Just thank you!!
I’ve been trying to do this but with no success, so far.
Thanks for the Video. It's really exciting.
Hell yeah !!!! I had exactly the same comments and design in mind you Did it before 😉
just fantastic,thanks for sharing.
Excellent project 👍
beautiful project
An interesting idea, despite the inaccuracy of that particular sensor.
Thank you so much sir...
LOVE FROM INDIA ❤❤❤
Could try microstepping the stepper motor and only triggering the sensor at each incremented step and only once data is received back, step the motor again . Could easily achieve 3200 data points at the cost of some stop start delay. Cool project👍🏻
Worth watching and subscribing
Use another TOF range sensor on the rotating head, symetrically. You’ll gather data faster
It looks like there are a place on the rotor for another TOF range sensor on the opposite place for the current sensor.
Tank you
Your brother from lebanon
Nice project!
nice job and great idea
I was making one lidar and I recommend you to put everything inside the rotating part and balance it. And also you could make it faster
this is awesome !!!
Wonderful and detailed explanation!!! in some part you mention about better sensors and link in the description ... I didn't find any recomendations somewhere .. what better sensors would you suggest?
the best.ty for sharing
One of the nicer projects I've seen. Please consider make an improved version.
Design looks like a world war I tank :D
Pretty good
Very nice
It is nice projects
Very nice tutorial 👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌👌
Thanks for the video! 0:17 is not an infrared distance sensor, it is laser-based: "The VL53L0X’s 940 nm VCSEL emitter (Vertical Cavity Surface-Emitting Laser), is totally invisible to the human eye, coupled with internal physical infrared filters."
0:46 getting some frame flicker there
WOW. I don't knwo wwhat that is....
@@ELECTRONOOBS subliminal messaging perhaps in order to buy from jlcpcb ? here is a screenshot of that flicker: i.imgur.com/TNDUpXt.png
@@ELECTRONOOBS did you use davinci resolve? I have this also from time to time. Do the usual full restart, avoid browsers and other apps while exporting and clear all caches in davinci. You may also switch some fusion nodes to software processing
@@panigrc You stole pretty much the exact comment I planned to leave.
@@panigrc It's obvious.
Great stuff. A larger diameter rotor would increase resolution.
awesome!!
Important note on the light sensor part number. The one in the video is the VL53L0X, vee ell five three ell Zero ex.
The confusing part number has both the letter L and the number zero.
For those who are interested in a slightly faster, and 4 meter range, try the VL53L1X. It needs a different software library, but it can use the same schematic and PCB. For those building their own boards, the VL53L0X runs at 2.7-ish to 2.9-ish. It does not work at 3.3 volts. The VL53L1X works from 2.7 to 3.4 volts.
For a project that uses 3.3 volts, the 1x doesn't require another voltage regulator and i2c level shifters.
Some 3.3volt Arduinos work at 2.8 volts. In my experience, USB ports continue to work with 2.8 volt data lines even though it is out of spec. I assume USB has a much lower noise margin and maximum cable length with 2.8 volt data.
Hello. I always watch your videos with interest.
Please, tell me in which editor you are making the video. Thank you!
Great Project Thank you, Where can I find the slip ring?
Nice 👍
great video! Thanks! How do you do the visualization? Which Software is it?
Make a video showing the tools you use it will be cool
Awesome ✌️✌️✌️
Good
Some more info on the stepup converter would be helpful!
As a building/programming exercise this is great. But there are complete 360° lidars available, for less than 100€, which also have much better specs.
There's the VL53L1X the bro of the L0X you can measure up to 4.5meter in mm !
Instead of counting steps what if you just used time? Since you have a hall effect sensor you could calculate the time the disk takes to rotate. Say we measure one rotation and it takes 5 seconds per rotation. This means that the front will be changing 73 degrees per second. So that means we could do something like f(s)= 73s so if we take a sample at .5 seconds using the time delta since the hall effect sensor has been activated we would get. 36.5 degrees. So depending on how you want your accuracy you can just change your sample rate. But given that the Arduino is having issues with just incrementing a variable maybe this wouldn't help. A raspberry pi pico might be a better fit for this since you could utilize multi-threading. Alternatively, if we know the sample rate we could store the expected angles and times in a dictionary. This would save on having to do the multiplication each time and instead having to look it up from memory. This would look something like this. Say we have a sample rate of once per second we know that our sensor travels 73 degrees per second. so we could say lookup = {1:73, 2:146, 3:219,4:292,5:365} this could then be accessed by the distance function. Obviously, for more accuracy, you would ideally have a larger dictionary with a higher sample rate.
Could you use a lens to focus the wide beam and get better accuracy and range?
You mentioned better distance sensors in the links below at 10:28, I couldn't find any in the description nor on your website? What did I miss?
Hello! Thanks for the great video. I need a LIDAR sensor to detect when an object trespasses an imaginary line limit. By customizing your project, can I achieve that?
Nice
I've never thought of this until seeing this video, but how do we account for the shape of the spinning head causing "inconsistencies". In the video we see the walls curves, since the spinning head is round, so objects close to it will obviously register close, but if we are scanning a straight wall and we may want to accurately represent the environment. How can we correct this?
My friend, there is a cockroach inside the box! It's a joke. Nice work!
00:46 IT'S UTAH!!!
great
What sensor on the lidar do you reccomend to use for an autonomous gps robot?
excellent video once again. i have some questions regarding the inverter video you made some time back. how can i reach you? please reply
If you're the guy in the intro you look like big Jay Oakerson a famous comedian.
Though it is clear that the sensor will no longer hold the properties of being a LIDAR when an Ultrasonic sensor is used instead of a TOF sensor, will it still work? The only difference will be that u have to play with the speed of light when using the TOF sensor, whereas with the ultrasonic sensor, u gotta play with the spead of sound.
Which setup you use in order to show the shape of the obstacles ?
Question, Anyway to focus or limit the field of view to be more accurate, like a cone or tube?
You can use maybe a lens or so...
Interesting, can this be applied to measure the water depth in a river
Banana spotted at 00:12
Easter egg? Seems to be the wrong season ;)
Sir make a video on long range racing quacopter
could you make a Automatic 3D scanner out of it if it detects inward instead of outward?
Yo queria hacer uno de esos, ¿cual es el maxima velocidad de giro?
sub'd based on the channel name alone.
Wow very interesting... if you put the sensor in a Z-Axis you can do a 3D Scanner?¿ Scanner Real object and pass to the 3dPrinter (Perhaps using Blender , reading an XML file with all the data from the sensor)
You mentioned there are better ToF sensors but haven't given the details. Can you please share them...
Big fan from India..
Notificarion squad
can't find the list for other distance sensors.
Can it go any faster to get faster data/results for faster reactions
Hi, I am going to make a LIDAR like yours. I will wrtie LIDAR data to a TXT file. But how will it be inside of the TXT file. What format should the data be written in? Thanks for answer
How do you make 3d models, liking scanning terrain using this?
Is there any upper limit on the RPM of the stepper motor?
4:12... What if you used a lens to focus the beam a bit tighter ???
Which link is supposed to have the better distance sensors?
What application is being used to display lines on monitor.
Погрешность кажется из за неравномерного движения модуля.
The error seems due to the uneven movement of the module.
Could you turn this into a 3d mapper for 3d printing object? Like a 3d scanner?
is there a way to buy the rotating support? ty
Can this lidar be used for bathymetric mapping?
How i can make the "tracking" application?
De que canal sacaste el video?
OH MY GODS
What is the max distance an object can be detected?
Can I rotate this in high speed?
