Nice video !

[@roudyalhaddad7409]

Can you plz share a PDF of the PCB

[@brotschuh]

really cool. but what are the 4 magnets around the coils for?

[@siddharthmali5841]

Sir Can you make video on magnetic flow meters?

[@kirk5452]

I love your videos! definitely buying this

[@ProjectPhysX]

Thank you for your efforts and for sharing all the information for free!

[@PrajjalakChattopadhyay]

This analog circuit seems to be pretty fast at response. Microcontroller based levitation circuits are generally slower due to the processing time of the microcontroller. Op-amp based or descrete logic based levitation circuits are very fast. You may think of an FPGA based levitation circuit. Love from India. ❤️

[@ArjanvanVught]

It really depends on your type of microcontroller. Using a FPGA seems to me pretty overkill.

[@thanatosor]

Prajjalak Chattopadhyay seem like programming the board itself to me.

[@respondwithquranandhadith3142]

Do you know that which sensor he has been used in this.if you know then please help me

[@JayElectroTech]

Hello sir, can you please tell me how it is controlling linearly with respect to magnet position, is it based on PWM or something? How controlling signals are applied to the H bridge driving circuit? Thankyou in advance

[@666aron]

I made an electromagnetic levitation device, which is the reverse of what you show (it only pulls the object), now I need this in my life.

[@NeroHat]

I am so grateful to see someone taking the time to explain the actual things you need to know. Quick question: I am assuming the potentiometers are for calibration. Do they help with accuracy or height of levitation. If you have played around with these potentiometers, can you please share some info on what do they allow you to adjust. Thank you.

[@Term-0]

at 4:03 there is a bubble that says that they are for calibrating the x and y for the hall effect sensors

[@profgallaugher]

Thank you for putting together this video. I purchased this product from Aliexpress but was surprised when there were no English instructions. I'm not (yet) a schematics reader, but it looks like your video and instructions will be very helpful. Much appreciated - thank you!

[@gautam5895]

Amazing tutorial! can you tell me what is the need to keep the hall sensor as tall as the coils???

[@devergeetoek9526]

respect for all the work you put into this man! big thumbs up! i also have diy but this is something else

[@larcomj]

analog control system, nice. That is rare in this day with uControllers everywhere. great video, you earned a sub. Keep it up.

[@rydude998]

If you refer to the Chinese schematic, or an ohm meter, you'll notice the X and Y sets of coils are connected in series. The opamp Hall control only modulates the field strength of the entire axis, not individual coils. If the magnet wanders up or down in the Y axis, the Y power will drop and likewise in the +/- X axis. The Z axis is only used for the comparator to turn on the circuit in the presence of a magnetic field.

[@JayElectroTech]

Absolutely correct, can you please tell me how it is controlling coils power linearly? , is it based on PWM or something? How controlling signals are applied to the H bridge driving circuit? Thankyou in advance

[@electronic7979]

Excellent work. I really like. I want to do the same

[@noealves8400]

cool device. thanks for sharing all the details!

[@MrWilliam932]

It's interesting, I'm thinking that by using an Arduino to control the levitator you should be able to control de position of the magnet in all 3 axis right?

[@ZouheirIbnabdeljalil]

Can You Make A Project That Combine The FingerPrint Door Lock And The KeyPad Door Lock To 1 Door Lock? ,With Admin Menu Maybe??

[@khaliffoster3777]

Can upgrade and make magnet locked so there is high resistance so you can't push down, so the magnet bouncy is much less, the up and down magnet field is less too, so you increase the magnet field, you decrease up and down so you locked it so can't push up.

[@tonysfun]

I have this kit, but I'm not able to levitate! The 2 adjustable pots (blue boxes) must have some "starting" value, but I do not know what that value is. Can you make the schema where you soldered the wires and use them as input on tour oscilloscope, so I can measure the values? What are your values? Thank you for your videos and help!

[@MikeRoss-je2zt]

Did you find a solution and get it to levitate? I'm having the same issue.

[@yunohero4981]

@@MikeRoss-je2zt im having the same problem, did you find a solution?

[@aaronvanmorris6005]

Same issue here. It seems like the Hall effect sensors are working and triggering the transistors but the fields aren’t balanced at all and the platform just falls to whoever side it’s closer to

[@mosta5]

I liked this idea of using sensors for 3 axes I didn't even think that this is possible .

[@TheRainHarvester]

I subscribed! Not sure why I never saw this channel before. KZbin is weird! I do electronic videos too!

[@OMNI_INFINITY]

Guess I am going to buy one of those. Hope I can re-use the electromagnets and ESC for a BLDC also. Seems doable. Maybe I'll make the BLDC first.

[@anishkommireddy4429]

how much weight does this top part carry to see it I could put a pot or a globe on it? Also how heavy is the bottom of the magnetic levitator. Also is there a way to reduce the weight of the magnetic levitator. Thank you.

[@chaitanyakulkarni2297]

I have tried your pcb design and found few issues which is 1. 78L05 is not connected to ground 2. Resistor values are wrong to maintain floating magnet

[@TMRu22311]

I purchased a diy kit but unable to make it work. I was sent a debugging guide showing a multimeter connected where the jumpers are placed. You have to adjust each one (Y & X) to zero amps, but mine is not reading anything :( The led only lights when the floating magnet is placed above, which is correct. What could I check to determine what is wrong with mine? Is there a way to check the coils to make sure they are working?

Amazing.Thank you

[@limtbk]

What are the coils parameters? How many turns in each layer and how many layers? What is the wire diameter? Does it contain iron core, or it wired around plastic with nuts on top and bottom? What inductance have that coils?

[@limtbk]

I'm asking because circuit itself is not big deal, all components are standard. But coils are not. And that's prevent me to repeat that scheme.

[@ELECTRONOOBS]

@@limtbk I don't know how many turns, The wire diameter is 0.25, the inner aluminum screw is 7mm diameter and the coil is 19mm diameter and 11mm height.

[@limtbk]

@@ELECTRONOOBS So, we have (19-7)/2/0.25=24 layers, each have 11/0.25=44 turns, so about 1000 turns in total

[@ELECTRONOOBS]

@@limtbk well, not really, that would be without the clearance. The amount is way lower. Here I've uploaded some photos for you. I count 30 layers and each layer has around 9 turns.

Coud anyone explain to me, why the Board needs the permanent magnets at the Corners?

[@Shabash7]

Nice project 👍🏼

[@tonysfun]

OK, I was playing with mine and I can't make my 2 magnets to do anything but crash! My 2 adjustable pots are not 10K but 100K!??? That is what came in the kit. But when I measure them, thy are 0-435K, so mismarked and they are not smooth when dialing in the values. I'll try to remove them with 10K matching once and I'll put them right in the middle 5K both. I also can't get the LED to light up like it did once year ago. (It just blinked and at that time, I didn't know what for. Now we all know that it's function is to tell you of the sweet spot position of the magnet!) OK so I soldered in new 10k pots, set them both to 5K, but I get the same results - no go! I have the same problem like most of the guys here mentioning: the magnets do not levitate but just push to any of the 4 side magnets. So somewhere is a problem that I can't figure out. Almost like a dead circuit, but I do get 12V everywhere I should. What are the 2 jumpers - some Chinese word above them - for? Are these some test ports? Are they there to enable or disable something important for calibration? Thank you for your videos! Happy new year 2021 and many more subscribers and supporters!

[@lucasmatsuoca]

is it feasible to discrete control something like this?

[@chrissre7935]

Mine when i turn it on the big magnet just snaps to one of the smaller ones at the side. No matter how in center i place it it randomly jumps to one of the magnet. Any solution what I could do wrong ?

[@samsont5813]

Does anyone know the name of the coils or where they can be bought individually?

[@bipolarchemist]

Don't know what coils they are, but you can probably make your own. The wire looks like it might be 24 or 26 AWG with about 20 or so layers. Not sure how many turns per layer or what the core is made of, but it looks like it might be aluminum and if the magnets are 5cm, then the overall coil length is approximately 15 cm. With something to serve as the core for wrapping, a few nuts, washers, bolts and varnish, you should be able to make something close to the ones supplied in an afternoon. I, personally, like to use bobbins for sewing machines as they are pretty inexpensive and leave you with nice looking coils.
