Lego Solar Powered Levitated Motor

[nbrwn9]

Hohow about a how to

[circlemer]

thats so sick!!

[SuperNoobdude]

SAY WHAT!?!?

[killerbeenl]

LEGO's :D I''ve once build a bedini circuit lego machine thingy --> Lego is ideal for testing stuf.

magnets

[JohnFMUTube]

Actual build time was around 3 hours. This excludes gathering/purchasing of materials. A time consuming part was figuring out a good combination of Lego parts to form the armature frame to mount the solar cells and wind the wire on. Glueing the small gears squarely in the hole of the magnet took some time.

That's a great idea to integrate this into a Lego star wars ship or space station. It would be cool to place it by a window and have something spin whenever the sun shines on it.

[Mrbandit81]

That's pretty cool looking, how long did it take you to build it?

Plus have you thought of building a Lego star wars ship around the set up you've got there, kinda like the center of a space station or a out post power plant?

[ChevyToughRebel]

Hmm, thats pretty neat

[francisroan]

nice.................

[wwwKx]

:O

[dustinkervodka]

does it work in sunlight?

[memoz1991]

the details link doesn't work :(

can u plz sent me the right link, Thanks in advance

[JohnFMUTube]

@memoz1991 - looks like the period at the end of the sentence is included in the details link, after the "htm" You can delete the period at the end to get to the details web site.

[invis45]

whats the use of this

[kattooMC]

@invis45 Amusement, I would guess...

[miszczmateusz]

free energy

[vuidehoc46]

cool i like it yearrrrrrr

[benjaminbreame]

not the most stable thing ever at the beginning. but at least it works

[CRAZYLEGOSMAN]

were do u get the waterpumps and this??

[geminirat60]

thats pretty cool

[spanglerangle]

how does it spin?

[JohnFMUTube]

@spanglerangle - really just like any motor. In this case, light shinning on one solar cell at a time generates an electric current to run through a wire coil. The current creates a magnetic field around the coil. The large magnet positioned on the base plate and the coil magnetic field are positioned to repel each other. The repelling force causes the movement of the coil assembly. Each solar cell when positioned in front of the light takes it's turn to generate a coil magnetic field.

[Mppgangster]

Its really cool, but Not really strong

[mastax1234]

your a genius



[LEGOBUILDER123211]

Cool!

[Srlancelot39]

omg thats soo awesome!

[bartleby451]

That Sir is very impressive, really very cleaver.

[onLove007]

cool

[fuelban]

hi guy nice video, my son was always building stuff with lego LOL, any ways you might want to look at this video { FuelBan Levitation Is IT OR Is It Not Levitation.wmv } keep making the videos guy, thanks, thom in scotland.

[MasterKnarf999]

that is AWSOME!

[LordDecapo]

i want instructions!! lol

[fagogarbejde]

cool

[cory1915]

whats the torque on that?

[JohnFMUTube]

@cory1915 a rough guestimation would be 0.0001 in-lbs

[dragonparty2]

@JohnFMUTube

wow...not very useful...but creative

[liljam97j]

@JohnFMUTube haha yea

[artoslo]

Could it actually power something, or is it relatively weak?

[JohnFMUTube]

@artoslo it is relatively weak. You could attach a small light-weight fan blade and feel a little breeze.

[ninggy369bhagwandin]

you could build fifty million and make a tank....

just a thought....

[Alexutube7]

very good idea! 5 stars Of 5 stars

[raferti7]

Вентилятор ПРЯМ, чем сильнее солнце, тем быстрее крутиться !

[theret5]

try putting another set of magnets on top to reduce bouncing

[JohnFMUTube]

@theret5 That is an excellent idea!

[vikenemesh]

@theret5 and balance the whole axis.

[gubalak]

very nice man .

[armand009]

excellent.........

[UntakenNick]

Did you make the coil yourself..?

[JohnFMUTube]

Yes, I made the two coils myself.

[frcz10]

jajajajaj apoyo a samuelbibi26 hablen en español!! Yo digo que el proyecto esta muy interesante..

[samuelbibi26]

mejor hablen en español

[MaterSammichMan]

Let's give credit where credit is due.

This is a Mendicino Motor.

[Nullflux8ight]

Wow, Can you tell me if you have four cells in total, the volts needed and is one winding hooked up to two cells and the other winding is wired into the remaining two cells? Was amperage more important or voltage to get this to turn as well as you have? wow!!! that's realy cool.

[JohnFMUTube]

Yes, four solar cells are used. Solar cells on opposite sides are hooked to the same coil. The polarity of the two solar cells are connected to the coil in reverse: e.g. the + of one and the - of the other are connected to one end of the coil. This way the solar cell facing the light will always result in the current flowing in the same direction relative to the permanent magnet located below. Be consistent in wiring the second set of cells so the two sets are not working against each other.

[JohnFMUTube]

The magnetic force is proportional to the amount of current so the amperage is more important than voltage. I used the solar cells available from Radio Shack with 0.3A and 0.55VDC. To determine proper wire length, use Ohm's law V=IR. Use the known voltage and current of the cell to determine the amount of resistance needed. Find the resistance per foot value of the magnet wire you are using to determine the length of wire needed for each coil. Be consistent on the wiring and have fun :)

[Nullflux8ight]

Thanks for your informative response. I'm going to give this a shot, it looks like an interesting conversation piece.

[315cesar]

cant w8 to se it in a lego car

how did you do that

[goldslinger]

Very Nice !

I did a video response with mine.

5 STARS

[dragonfire1505]

cool how you do that

[autonomous2010]

wow... I tried to make one like that and I guess I had the motor specs wrong because I fried the motor after it started to spin really fast. :(

[mtncal]

Brilliant

[nocturnsbro]

erm... have you thoght about using it in a model?

[JohnFMUTube]

the motor may have limited torque but that is a good idea to try. We'll have to think of a good application to try.

[Alexutube7]

so cool.
