Cool project. The loop basically has a fixed pulse-width and frequency but will skip power pulses as needed based on the analog reading (bang-bang style). I have observed this phenomena on SMPS when no load to med load was introduced. I like the addition of the rare-earth magnets to stabilize the bolt. Figure ~13clk for the ADC, ~4clk for the if statement, and ~100clk for the digitalWrite = ~117 clock cycles roughly for this whole loop. Encasing the loop statements inside of a while loop inside the main loop will add more stability:
loop()
{
while(1){
analogRead;
if(conditional) digitalWrite(pin, LOW);
else digitalWrite(pin, HIGH);
}
}
If an oscilloscope was used, say on the output of the hall sensor, you'd probably see something like a sawtooth at roughly 133kHz.
hahaha, your neighbors radio will play your tunes ;)
is it possible to increase the height of levitation and external load what component will plays important role for that power of electromagnet or side parmanent magnets
This is an awesome project. I made a similar but smaller setup but using a solid core coil that repels the magnet as it tries to attract to the core. The ring keeps the magnet generally stable in the middle. This one looks extremely stable though and can hold some good weight.
I would also like to make a similar project, is there a tutorial you followed or how did you make it work?
@@omrek001 There was a lot of trial and error. I ended up trying out different variations of this one, and the suspended magnet from an overhead coil, and ended up doing without the arduino once I found a combination of hall sensors and transistors which seemed to work, which were AH3503 sensors and TIP120 transistors. It's a little easier with the arduino because you can program a "set point" in the code and change it on the fly. This video here is a good tutorial on how to use the basic arduino code though.
This basically involved monitoring what kind of voltage rise or drop I could get using those sensors and my magnets of choice, moving them around the distance I planned to suspend the magnet. This would cause the sensor to output a higher or lower voltage right around the ON voltage of the TIP120.
I know I made a few levitator videos but can't recall what useful info I had in there if any. Here's one such video showing a few versions. ruclips.net/video/zpvZ0fD38qk/видео.html
Would maybe an simple switching analog circuit work too?
Setting up a circuit where the hall effect sensor output is driven directly to the transistor base, with some sort of setpoint adjuster, like a potentiometer.
Undoubtedly a great project, a nice effect achieved in a simple way.
I'll try to build one myself for sure xD
Thanks for sharing!
Very interesting for educational purpose in elementary school. Thank you.
Built something similar 50 years ago for a science fair. Called a repulsion coil. Could shot a 3 inch diameter aluminum ring several feet into the air, or levitate it. I was 12 years old at the time and won 2nd place at Texas a&m university.
what came fist place then ? a time reversal unit? yours would have been a hard act to follow at 12yo and 50 years ago but its a shame we still must use dirty and expensive gasoline i know of 2 suppression examles one here in australia early 2000 and one in the uk late 90s both suppressed cheers , they wont let us change the world for us will they
@@charlesmagro8757 bet is was a mock-up volcano that got first XD
Magnets levitation, Arduino Project and Boards of Canada look and feel... Perfect!
Out of sight! Love the music, too. Reminds me of my yoga music. Fabulous job!
That wasn't so bad, I wouldn't call it repulsive.
LoL
And what is it for you?
the opposite of you... jkjk
This is the best channel of RUclips. 👏👏👏👏👏👏
Nice. I tried to make one for the science fair in middle school, but I never could get it balanced no matter how hard I tried. I wish youtube existed back then :P Then again, this one isn't passive and uses an arduino, something I also didn't have access to. I guess I aimed a bit high that year :P
balancing passive magnetolevitator is a very tedious work
After days observing finally i understood why that nail is needed on top of the magnrt... you should explain more clearly tho... no wonder the south pole facing to the north of the levitated magnet its pushing the nail to keep the magnet from falling bcoz the nail is south...
I had to look up a hall effect sensor. That's cool. I was just watching some guy make a visual magnetism indicator. He poured yellow highlighter ink into mineral oil. Added iron filings into a small container. Like a hand sanitizer bottle. put it next to a field and you'd be able to see the field change.
Thanks, you helped me understand the principle of the problem, great
This White Floating Box with four motors with i guess also four magnets on the motors floating very smoothly above a alu or copper plate.Its awesome.Think about it when all our streets would be copper we could float above the ground in any possible vehicle? Electric of course ,or water based or solar powered.Its odd.

Better to use fish paper than clear tape for insulation. Also better to use iron core or even a nail for a core than air core as the current will quickly heat the wire where the enamel will melt with this design. Also there is a red fiberglass board that is available in even 1/16" that is much safer than using wood, as it is designed as an electrical insulator.
If he used an iron core, the neodymium magnet under the screw would get stuck to the iron core and wouldn't levitate. Well, maybe it would, but it would be much harder to control.
@@Alkis05 This is excactly what happens to me at the moment. It's frustrating!
@@Johncowk What you could do it to find a more sensitive sensor so you can use the weakest neodymium magnet. That way it can levitate high enough so the force applied by the permanent magnet is negligible. It falls with the square of the distance, after all.
Good coil making technique and skills!! Nice project!! Thanks!
Fantastic video. Very good matching music as well. Thank you for uploading :)
Really super
真厉害，牛，咋搞的，全都是英文，这是为难我英语课代表啊
Artesania de 8 bits! 👏🙌👏
Could someone explain why the diode is needed in this specific configuration?
Where in the video does he link the coil wires with the diode? The schematic clearly has a diode, but the I don't see one in the video. The red wire from the coil is soldered directly to the Arduino. Which version is correct? Or where is the diode in the video?
very nice simple project, congratz
Nice video bro
Peacefully art! Very relaxing view.
use this circuit in microwave oven magnetrons so we got frequency controlled microwave oven so we can evenly cooked food in same time since frequency goes low and higher like waves, sine waves so our food cooked without any extra burning
Very nice project. I you had a 3d printer, you could actually make it look very nice and it would be more accurate. I will try it myself. Thank you for sharing
Thank you! This really helped me make my project. :)
Good job
Very nice! It is pretty hard to get right.
So did you use a relay at all or no? I did my math and my electromagnet needs 1.1 amp at 12 volts because of the wire resistance. At 5 v it would be around 0.5 but arduino still won't be able to do anything. Secondly I tried making a single electromagnet with both polarities. To phrase that better I used two relays to make the electromagnet switch from attraction to repulsion and back to keep the magnet from flying sideways. I am still not done as the relays are drawing a lot if power from the board and then I feel like due to their quality their springs get stuck. I might be wrong. I might be right. But I can really use some ideas and suggestions.
BTW I am a mechanical engineering student too just wanted to have a fun project and I got inspired by you.
Nice. Code acts as comparator with variable reference.
Or like a linear Inverter(op amp).
Very cool video.
Nice project.
If I am not mistaken, you actually measured the resistance of the coil, in parallel with that of your body!
it doesn't matter as it is in a range of tens to hundreds kiloohms
This is amazing!
Thanks for sharing.

Hey what's the music you use in this? I find it super relaxing
It is The Ambient from Kevin MacLeod
@@hobbyprojects thanks
You wasted alot of my time doing a fake the only thing I can think of is I'm using just over 1 amp and 12volts piss take I ain't a well kiddy I don't need it.
Have you anything to say can you tell me if it's a fake or not because I'm getting stressed I done it to perfection
@@hobbyprojects what is hobby project
Isn't that design a little like how an alternator works with the permanent magnets on the outside and a field magnet inside? think I saw that on jeremy fieldings youtube page
why do you need an arduino for such a simple program? Simple LM358 with the potentiometer and couple of resistors would do the same
You can watch the simpler version without coding here ruclips.net/video/1BN3K6ACc08/видео.html
I suppose you need that transistor as a switch because the arduino doesn't supply sufficient power as is to the resistor and the coil.
It's so amazing👍🏼
It is very cool.
Your project is Awesome
Can i use ky 024 Hall effect sensor instead 482 Hall effect sensor
What properties in the bolt allow you to do this? Trying to figure out what other objects I can use instead to levitate
very nice job.
The electromagnet gets very hot after exceeding constant use of 30 minutes. Is it because i do not use a core in it? can i use a cor? while it effect the system's operation?
When I wind the coil wire and apply current, it does not gain magnet feature. What should I do? Does the coil wire you use have a feature?
Good
Thanks!! Nice job! (I like the music, quite unusual in this kind of videos. Thanks for that too!)
Glad you like it!
I cannot find the liner hall sensor 482 938 on the web. Is there a substituted for it?
Wow !! Oh Cool !!
Wow! This is best 😯
Can you help me to making this project
Porque juguetes, muy buenos? Ya que siga el mismo modelo pero a escalas grandes
excellent work..
Can I substitute the 482 hall effect sensor with 3503?
If I use 4 coils with 1 big ring magnet then how can I attach all coils each other. Please reply
did you find the answer from somewhere man?
I am looking for the answer too
awesome. thanks
I found this rather attractive actually.
nice
Great!
Hello, do you do Magnetic Levitator with PID? If yes, where can I find that project? Thank you very much.
Did you find it?
Hello there. What do we have to do to push it higher?
how much current your levitation is using ,,, by the coil with 26 ohm and 12 volt. i have just 7 Ohm coil and 300mah current /12volt ,my coil is centert in a Aluminium stick , so that i can ajust the coil niveau very easy (high&down ) , it works very stabil with 8mm levitation distance , i am very happy for this challenge ,and fight for it till it s done , i look myself to make a video for this cute pretty very cool new update 2019 device , fully reduction prinzip , but it must said , it s more heavy to build it , than the hang version , remark : my version circuit is identical with yours , but without the 5 Volt IC stabi , so one part less , it do not need the 5 volt stabi .
Total 220ma by the 26 Ohm Coil and 5 Volt IC
Does a hall sensor 3144 work the same as a linear sensor 284
Nice work
Nice
Good morning, I would like to know what transistor you use?
Its TIP 122
@@hobbyprojects Do you have a parts list for this project?
Hello everyone !
I have a question, if anyone can hlep me, i will apreciate.
I wanna get this levitation more stronger, so If i change the magnetics for a Hard drive magnet i will need to change the coil ?
Sorry for possible english mistakes. I'm not a good speaker. Thanks
Will it work with a small magnetic sphere?
Can you provide with the list of materials used in the video please????
What if i use A-3144 DIP Hall Effect Sensor instead of yours?it still works or not?
According to Datasheet A-3144 needs 5v but during testing it was working on 3.7V battery also. You can try it.
@@hobbyprojects allright man thank you,i will try it out with 5V and then comment here what happens
@@alih.dasdemir4290 so? Did it work?
@@satriyokinayung7030 i couldnt manage to complete the project and i dont know what did i do wrong, for a reason it didnt work, so i dont know if that was because of the sensor or not.
Briliant! But I dont understand how it is possible to spin it
A seven stack might get us in space
It’s not levitation It’s magnetic suspension. Float the ring magnet. And you can call it levitation Raise the platform not the bolt
Man, where can I find friends as smart as you guys? Impressive people.
Can't find the schematic. Where is it?
Schematic is already in the Video ruclips.net/video/ZgWHu28xXuQ/видео.html
Old is Gold
Keren
it be awesome if you can crack the magnetic motor conundrum
Why did you set the set_point value of Arduino to 300?
NICE 4 STACK
Доктор! Есть в этом кинотеатре доктор? Где доктор Дью?
Can I use linear hall sensor A3144
can You able to make a slightly biger version of it?
No! That would warp time-space, very inadvisable!
Would it work the other way around? upside down?
that's easier to do, because you can make automatic stability when you do it like that, but uses different code I believe.
If you want it to be arduino, create.arduino.cc/projecthub/jsirgado/magnet-levitation-with-arduino-eeeee4
edit: I found out you can prob do it. get rid of the ring magnets(in this they support stability, and act as gravity, but you don't need either of them upside down).

are you listening what l says in my comment, use neodymium magnet or electromagnets in microwave magnetrons so we got frequency controlled or modulation for better cooking
Cool !!!! *what's holding the Screw* is it a magnet or metal or aluminum ?
Magnet
@@hobbyprojects any type off magnetic ? 😁 or it has to be specific type of magnetic
The coil is south the perminant magnets are south and the levataion magnet is north where is the repulsion
that was amazing job what you did, I did the same but I got some difficulty. How can I contact you, I have a few question about it could you please answer me. I want your Insta
