Magnetic levitation shield for Arduino Nano. This shield is designed for use with objects such as Ekobots - Levitator with Arduino. You can purchase the shield at OSH Park: https://oshpark.com/shared_projects/kxH3Ak1b. It was published in OSH Park by Thingiverse user krwynn: http://www.thingiverse.com/krwynn/about. Thanks! To assemble this project, you'll need: * 1x Arduino Board (Nano) * 1x Electromagnet - ZYE1-P25/20 12V, 25mm diameter, 20mm height ($7.00 on eBay) * 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 ($2.00 on eBay) * 2x Micro switch Arduino firmware: * Levitator.ino - For normal people with a life and girlfriend * Levitator_PID.ino - If you don't have a life or girlfriend, or if you have any kind of mental disorder, it was made for you. I'm testing a new firmware with safety mode that turns off the electromagnet in case of a fall of the permanent magnet. Working mode: * The switch "+" increases the distance from the electromagnet. * The switch "-" decreases the distance from the electromagnet. Check out 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 alters the sensor's real value for the permanent magnet. * Mount the hall effect sensor as far as possible from the electromagnet. * Use neodymium permanent magnets (it won't work with common magnets). * Use soft wires to make easy assembly, small box, remember. That's all folks!
