Ekobots - Levitator with arduino. by jsirgado

Last crawled date: 4 years, 1 month ago
Magnetic levitation toy with arduino.
Easy to print and mount (Just some glue, no screws).
Just install the firmware(Levitator.ino) in the arduino board.
Do not need a computer, just the 12V power supply, after install the firmware.
With a stick use the switches to adjust the magnet position.
Use the arduino serial monitor to see the correct value for you.
You can hard code the correct value in your toy.
I put all parts you need in 1 plate, have fun.
My videos:
Video 1 (3x block magnets 10mm x 10mm x 3mm + 8mm x 30mm threaded rod):http://www.youtube.com/watch?v=w-jtu5cxl9o
Video 2 (1x cube magnet 10mm + Ufo_01 3D printed part):http://www.youtube.com/watch?v=nXplyDKqs2s
Video 3 (2x cylinder magnet 20mm + 5mm):http://www.youtube.com/watch?v=AIz9ystIPUo
All you need:
1x Arduino Board (Nano to use the shield);
1x Electromagnet - ZYE1-P25/20 12V, 25mm diameter, 20mm height (ebay $7.00);
1x Linear hall effect sensor - 49e (ebay Kit 5 - $1.50);
1x Magnet cube 10mm (ufo_1) or magnet sphere 10mm (ufo_2);
1x Darlington Transistor NPN - TIP120;
1x Resistor 1K ohm;
1x Diode N4007;
1x Power supply 12V 1A (ebay $2.00);
2x Micro switch;
Attention:
Put the hall sensor in the bottom of the tip(top_sensor.stl) see the images;
To work correct, the hall effect sensor must be at least 5mm of distance from electromagnetic;
You can use other linear hall sensor (do not use hall sensor switch);
Use neodymium permanent magnets (it will not work with common magnets);
Heavy objects are more stable;
Think it is hard:
Use my arduino nano shield:http://www.thingiverse.com/thing:1392530
.
You can order the shield at:https://oshpark.com/shared_projects/kxH3Ak1b

Thanks!

See my "Makes" for more details:http://www.thingiverse.com/make:201394http://www.thingiverse.com/make:201420
Possible upgrades:
Safety mode in the code for the toy(in test):
Turns off the electromagnet in case the permanent magnet fall;
Curved arm to hold the electromagnet:
Bigger objects and more free space;
Hall effect sensor below the permanent magnet:
No electromagnet interference, accurate measurements and more stable levitation;
It is a little better than the prototype! ;-)
