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!
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👍🏻
@@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
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."
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?
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?
I am using laser range finders with WEMOS D1 Minis. I am using the VL53L1X instead of the L0x. Note that the part number has a zero, not the letter O. I using a laser range finder library from sparkfun.
Yes, you can! I made one, in my version the lidar can make a measurement in 3D space and send through WiFi to a Python plataform. That is my course conclusion project! And it is open source :) linux.ime.usp.br/~brunobra/MAC0499 (sorry, I don't have an english version)
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
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.
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.
@@ELECTRONOOBS did you use the serial reading from the com port to plot the distances of the sensor in a canvas like points? How do you make it to plot in x and y? Ohh with an angle, oh that's why you have a hall sensor there. So did you use the velocity of the motor constant to calculate a resolution (number of readings) given the rotation and then ploting with an increasing angle, up to 360° Forget my questions, i'm figure it out there with time.
@@chikitronrx0 electronoobs.com/eng_arduino_tut110_2.php see codes here... You get angle and distance adn using sin and cos you can pass from polars to cartesians and plot them in Processing!
Amazing project but I have one question... How did you download processing. because now they don't let you download software until you make donation...
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?

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
Dude i must say that you are one of the greatest electronic channel here in youtube, you have so much passion
Thank you!
Maybe you should have corrected measured distance with relative position of sensor to the center of the spinning disk. Anyway, good job.

This is a brilliant project - it covers a range of interesting concepts - sending data through a slip ring, etc.
That device is like a 360-version of the popular arduino ultrasonic radar. Great job :)

@@panigrc You stole pretty much the exact comment I planned to leave.
@@panigrc It's obvious.
Thank you man I waiting for this
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.
An interesting idea, despite the inaccuracy of that particular sensor.
You put out some of the most interesting projects. Thanks for sharing.

How do you make 3d models, liking scanning terrain using this?

What is the use of this lidar in everyday life
this is awesome !!!
Could you turn this into a 3d mapper for 3d printing object? Like a 3d scanner?
could you make a Automatic 3D scanner out of it if it detects inward instead of outward?
what is the range of the lidar sensor?

What is the range of your lidar???pls reply
can you make a similar device using ultrasonic sensor
Some more info on the stepup converter would be helpful!
What is the max distance an object can be detected?
Design looks like a world war I tank :D
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.
You mentioned there are better ToF sensors but haven't given the details. Can you please share them...
