Repulsive Magnetic Levitation using Arduino - Simple Design

[@RinksRides]

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 ;)

[@abdulrehmanfruqi9930]

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

[@Magneticitist]

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.

[@omrek001]

I would also like to make a similar project, is there a tutorial you followed or how did you make it work?

[@Magneticitist]

@@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. kzbin.info/www/bejne/sKHZi2OceZhrp80

[@zvizionaero]

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!

[@truetexan7755]

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.

[@charlesmagro8757]

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

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.

[@PhamThanhKhuyen]

Thanks, you helped me understand the principle of the problem, great

[@syahrul9282]

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...

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

[@jskratnyarlathotep8411]

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.

[@Paul-gz5dp]

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.

[@Alkis05]

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.

[@Johncowk]

@@Alkis05 This is excactly what happens to me at the moment. It's frustrating!

[@Alkis05]

@@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.

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.

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

[@jskratnyarlathotep8411]

[@jskratnyarlathotep8411]

it doesn't matter as it is in a range of tens to hundreds kiloohms

[@shayankhanzada4987]

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.
