Magnetic levitator shield for arduino nano. This shield is for use with ojbect: Ekobots - Levitator with arduino.http://www.thingiverse.com/thing:1392023 You can order the shield at:https://oshpark.com/shared_projects/kxH3Ak1b It was published in OSH Park by Thingiverse user krwynn:http://www.thingiverse.com/krwynn/about Thanks! 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; Arduino firmware: Levitator.ino - For normal people, with life and girl friend; Levitator_PID.ino - If you do not have life and girl friend or if you have any kind of mental disorder, it was made for you... ;-). I am testing a new firmware with safety mode, it turns off the electromagnet in case of fall of the permanent magnet. Working mode: The switch "+" increase the distance from the electromagnet. The switch "-" decrease the distance from the electromagnet. 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 (1x sphere magnet 10mm + 8mm x 30mm threaded rod);http://www.youtube.com/watch?v=AxjHF56DeiQ Video 4 (1x cylinder magnet 20mm x 5mm):http://www.youtube.com/watch?v=NttqFqB-nu4 Video 5 (2x cylinder magnets 20mm x 5mm):http://www.youtube.com/watch?v=AIz9ystIPUo Video 6 (2x ring magnets 19mm x 5mm):http://www.youtube.com/watch?v=k7yBUj8GIgU Video 7 (1x sphere magnet 10mm + Ufo 3D printed):http://www.youtube.com/watch?v=3VHKrIAETCA Video 8 (Prototype version test):http://www.youtube.com/watch?v=HpFQfXAwKzI Attention: See the images to mount the hall effect sensor; The electromagnet alter the sensor real value for the permanent magnet; Mount the hall effect sensor as far as possible from the electromagnet; Use neodymium permanent magnets (it will not work with common magnets); Use soft wires to make easy the assembly, small box, remember; That's all folks!
