How many watts are the 2.2K resistors? 2.2K resistors sometimes are 1/4 watts and others are 1/2 watts so which one did you use?

AND MORE QUESTIONS..
1.THE ONE R2 1K IN THE MIDDLE IS A TRIMPOT?...AND WHATS THE USE?TO ADJUST ...CALIBRATE THE LEVITATION?
2.WHAT KIND ARE THE CAPACITORS ONE BY ONE..FROM THE C1 TO C5
3.CAN I USE ANY P CHANNEL MOSFET WITH ABOUT THE SAME CHARACTERISTICS..OK THE ANSWER IS PROBABLY YES!
4.THE RESISTORS ARE RATED 1/2 1/4 WATT??..WHAT IS THE VALUE?
SORRY FOR THE SIMPLICITY OF QUESTIONS ..I DONT KNOW ABOUT ELECTRONICS...

WHERE CAN WE FIND THIS ELECTROMAGNET...CAN WE GET ONE FROM EBAY?THESE ARE RATED BY THE VOLTAGE AND THE WEIGHT THEY CAN HOLD..CAN YOU RECOMMEND ONE FROM THERE..?WHAT IS THE MAX WEIGHT YOUR DEVICE CAN HOLD?20-30GR?ITS SURELY THE SIMPLEST PCB AND YOU DONT USE IR SENSORS THAT MAKE THE DEVICE UGLY AND BULKY!!
P.S.WHAT TYPE AND SIZE IS THE TOP MAGNET ON THE COIL..??THNX IN ADVANCE!!

Transistor IRF4905 is not available.For option with transistor is set in this circuit.Tell me sir.

Greetings sir;
Could you please send me the detail function and structure of the above circuit,because in the circuit you used741 but I can't find them on images on board,please guide me to do this ,I am doing my final year project
My mail id:mrkintent@gmail. Com

I don't know how to solder is their any way I can buy one all ready put together if so let me know my email is ericolympia53@yahoo.com

Hello again.

Can you describe your permanent magnet? Is it polarized sideways or vertically? And if vertically, is it attracting the ball (aiding the electromagnet) or pushing the flux of the coil downwards so as to extend the range it can pull the object?

Thanks

Hi, greetings from the Philippines.
Nice work! I tried one without a permanent magnet on top and used only a steel to be levitated. It didn't work and my coil always gets hot. Very, very hot. So I'll revise it with a circuit that would kill the power if there is no object so that it won't energize the coil for too long.

Thanks my friend!

Hello Sir :

Where to buy such sensor by online ?

Can I order it from you ?

Regards,
Samuel

A3144 will this sensor work for this project??

Hello,

this is really a beautiful thingie :)

How important is the 5V regulator? If I was to run the whole thing from a 12V regulated power supply with TLE4905, would I need it?

Ich frage mich, wenn Sie mir sagen, was der Widerstand und die Drahtstärke (oder Drahtdurchmesser) Ihrer Spule ist? Entschuldigung für mein schlechtes Deutsch.

I was wondering if you could tell me what the resistance and wire gauge (or wire diameter) of your coil is? Apologies for my poor German.

Hi, I have a question:
Which material is the coil's ferromagnetic core made of?

HALLO, OK, ich bin brasilianische Physiker, und ich habe schon ein Haus Levitator ich mit infraroten gebaut, aber ich weiß, tolles Design, sehr gut. Ich habe versucht zu replizieren, verwendet der Hall-Sensor SS 41, und es hat nicht funktioniert. Nur funktioniert gut mit SS 495 A. Meine Levitator in Betrieb, wenn die Spule ist verschwommen und ich war der Transistor 2N 3055, denn ich fand Ihre vorgeschlagen. Grüße, Luiz Cosme.

Hi,
Where can i buy such a product?

Hi,

Hi I have a question, would this power supply work for this project:

http://www.ebay.com/itm/NEW-15V-1500mA-1-5A-AC-DC-Power-ac-adapter-Power-supply-/290372975606?pt=LH_DefaultDomain_0&hash=item439b93fbf6

If not is it possible for you to link me to a power supply on eBay (I live in Canada)?

Thanks!

Architecture student from Canada here. I need to make this as a part of a final project. Your scheme is by far the simplest/elegant I found online. Just want to say thanks for this great article :)

Hi, very nice and interesting project,please i have two questions...would change if you don't use a sphere, but a magnetic neodymium disc..do you believe that levitate the disc? How much does sphere weigh? it's 3/4'', does not it?

Greetings from Ecuador

I\'m a big gay and I love dick ;) ! I research I big boy :p

http://www.electroschematics.com/6306/magnetic-levitation-circuit/
is a simpler project for beginners

Can you please mail me at patelmrudul352@yahoo.in

Answer: You need to build yourself a bobbin. Take a plastic pipe (ballpoint) and glue two plasic discs on it. Now wind the copper wire around ;-)

Please help me..... I have to submit my project in 5 days.......

Can you shown me the way I can make the same project but using ir led receiver and transmitter and I am not getting an electromagnet can you help me to make it at home with something else ?

Hi Giorgio,

I too had same problem, I added R,C suggested by you, for me it works great. I have put LED across coil and it glows when object is in levitating range(good for kids).

Thank you,
vu2iia

I had a problem: when the magnetic sphere is not floating, sometimes the MOSFET is always on and the coil warm a lot because it sink 0,9A @ 18V (16W). To avoid this behaviour I put a 1uF 63V between PIN6 IC4 and gate T1, I also add a 100Kohm resistor between gate-source of T1. In this way IC4 can\'t keep T1 always on but it can drive it on and off.
It worked also without these components but few times the coil became very hot.
Thanks for you great project and for sharing information.

Giorgio

Answer: Thank you for your good idea.

Thanks! I made it and it works. In future, I plan to make slayer exciter to light a small CFL bulb while being levitated.

Do you have any plan to make maglev cradel circuit in future? I look forward for it.

Good work and thanks

Hello,

I'm french and I would like to realise your magnetic levitator. I can order the components on the website conrad.fr. Could you please tell me if the capacitor " MKS02 100nF 63V Pas 2,5mm Wima" (reference 455008-62) can be used for the three 100nF capacitors. Moreover, I can't find a soft iron cylinder for the coil. If I replace it by a rod magnet, will it work or not ?

thanks

Thibaud

Original version (2007 feb.):

Why did you choose to power this with 15v? Why not just use 5v and skip the voltage regulator?

How does the hall effect sensor measure only the magnetic field of the ball? how do you discard the varying field of the coil?

OK!! I finally managed what I wanted! 3.5 cm from the sensor, 5 cm from the electromagnet. The new coil is made with 0.4 mm wire and the core is many i cores from a transformer. Read the description of the video for more info:

Hello from South Africa.
I am trying to wind the coil, so far without success.
What is the resistance of your coil?
Thank You.

Answer: Sorry, but I don't know the resistance of the coil.

Hello, I'm a french student, I would like to have information about the electromagnet, because we have electromagnets but they can't attract thing from very far, or yours can, my question is: How did you make your electromagnet ? number of spires, the diameter of the copper wire, and any other details that you may have.
If you could e-mail me all the informations to vladimir-trois@gmail.com

Thank you very much for your help.

Answer: The number of windings of coil is unknown. The wire diameter is 0,35mm and the dimensions of the coil are 32mm diameter and a length of 32mm. The inner hole is 12mm. So you can calculate how much windings we have :-)
I had a coil body from a scrap electric and wrapped the coil itself (Drilling Machine).
It is important, you have an iron core for the best results!

Please share details of the electromagnetic coil that you recommend, what is the supply voltage to the coil. also if you can share the detailed dimensions of the aluminium piece which holds the electromagnetic coil. Is the magnet sensor that you refer to is actually the Hall effect sensor ?
Please share an exploded picture of the aluminium cuppola
Thankyou and look forward to your help

Answer: Yes, the magnet sensor and the hall effect is the same.

Thank you for sharing. I did replicate you circuit but used solenoid coil from dishwasher. Works just fine. Youtube - blackchisel97.

Regards
V

I dont undertand how mount the coil,
Explain in english please?
diecavallax@yahoo.com.br

Answer: The plastic pipe - secondary coil - is inserted to a steel flange and are self-retaining. The flange is screwed to the base plate.

quanto costa?

Rispondere: Inestimabile :-) Quindi invendibili!

hello again, thanks very much for you reply...
I only have here the UGN3132U or KMZ41 or SS549AT or TL172

Answer: Hello, it is really difficult. I don't understand the datasheets from your components.

For the best results you need a analog output. The SS495 has a supply from 5V and a output from 2,5V (without magnet field). That ist the half of supply power. Comes a magnet field in the near, the output change to high or low, depends from magnetic pole. The sensity is 3,125mV per gauss and the absolutly range is -670 to +670 Gauss or -67 to +67mT. In the datasheets from your components, I missing this information. So I'm not sure if it works.

Or you can take a digital output (Schmitt trigger) like the TLE4905L/TLE4935L. This switches on at 18 mT. I think the TL172 is good but this need 7V. The UGN3132U is also a candidate for testing.

I saw a large version of this at Cal Poly (college) in San Luis Obispo (central coast of California, USA) in the late 1960's at their annual festival 'Poly Royal'. Thanks for showing me what they did. Theirs was 4' high, and the suspended item was a steel globe of the earth. Weighted at the bottom, it sat there spinning slowly. Even got the direction of rotation right. Very clever. Thanks for the diagrams.

Answer: You're welcome

hello again, I can get the AH211 TWO PHASE HALL EFEECT is possible put this

Answer: No, the AH211 is not suitable but you can take the TLE4905.

hello from argentina bs as, south america, thanks for this grat projet, here is very dificult to find the SS495A sensor is possible put some other do you have ideas?

Hi

The resistor R1 and capacitator C2, what is it for?
Has it something to do with the frequency ??
Sorry i am just curiuous :P.

Hello.

Where I can get the coil.?

In the event that the build myself, where the ferromagnetic core bag?

Thank you and congratulations on the project.

Answer: A coil to find , that is really a problem. You must be creative. Either self made or looking at ebay.
The ferromagnetic core is very simple. You can take a big nail or other magnetic steel.

Hello,
May i ask you why there is a feed back?
I dont know what it really does.

How much is it cost ??

Answer: It´s unsaleable :-)

Hi! Nice project. Very simple circuit compared to others I have seen. Could you explain me the role of the magnet on the top, and the role of R1, C2?
I have tried it without the magnet on top (I didn't have one), but the flying magnet strongly oscillates at low frequency (just a few Hz) and does not stay into a fixed position.
Thanks!

Answer: Well, it´s not easy to explain the role of the magnet on the top. First, it will work without this magnet but the floating distance will be smaller. For the best result you must try it.
The resistor R1 and the condensor C2 are a feedback-loop and stabilized the work of the coil.
If your magnet oscillates is your magnet too heavy or the coil to small. Take one a smaller magnet and the frequency will be higher or you boost the power supply.

Great project. I could not find the connections of the SS495A in datasheets available on the Internet.Could you tell me which leads (1-2-3) correspond with +V - GND - OUT?

Answer: That's really a problem. I also couldn't find it in datasheets and I try to found the connection at the time.

Oh, my email is ttnemk@hotmail.com
thanks!

Hi, its me again, I found the english version. How about posting a video showing how to make the coil connection to cables and the circuit board? Im actually interested in building a floating Globe, with just a base magnet and a magnet holder inside the Globe. I dont think the upper part of your device is needed if you have a flat top. Thanks.

Answer: The connection is very simple. I have it hidden in the brass bearers. One side is the cable for the coil and the other side for this sensor. You can see it on my pictures. A tutorial video is too many work :-)

Now to your floating globe project. That´s right, you need only any base magnets and coils to floating a globe (and one into the globe). This is one of a future project for me. Are you interest? i have a good site (check this).
First i would tried floating a magnet (two or four magnets on a plate), like my mendocino-motor (check my other projects). Now the plate with this magnets will brake out to a side, now you take a coil with sensor (one of each two sides) and use this circuit, i have used, to regulate the position. Thats all! I hope so, i dont have try it.
Have you the first results of this, let me know it. Good luck!
