Coming soon: A remix version of the Gravitator project using an Arduino Uno + proto shield !! EDIT 2019/03/04 Added a V2 board and schematics with optional DC-DC 5V converter for improved stability. EDIT 2019/03/01 Added more pictures and updated videos. Released Levitator firmware 1.3 Released LevitatorHost 1.6 EDIT 2018/02/21: Improved Arm and Coil Cylinder fixation. Updated base for USB mini connection. Added Assembly and User's manual. This is my take on the Gravitator project, a magnetic levitation system using an Arduino board. As a child, I was fascinated by the concept of floating objects in mid-air without any physical contact. After years of tinkering with electronics and 3D printing, I decided to create my own version of this technology. I've printed all parts at 0.25mm, 25% infill. 1 x Base-Bottom : support doesn't matter 1 x Base-Bottom-NoBTswitch: (if you don't want bluetooth or don't intend to turn it off) 1 x Base-Top : support >45° overhang 1 x Side : no support !!! (otherwise you'll have difficulties to clean up the conduits. 1 x Sensor Holder : support >60° overhang 1 x Sensor Cap : support >60° overhang 1 x Cylinder Body : support >45° overhang 1 x Cylinder Top : support doesn't matter 1 x Cylinder Cap : support >60° Hardware: 1 x Hexagon socket head cap screw M6x40 mm 1 x M6 nut 5 x Self tapping screw 2.9x13mm 2-4 x M2.5x5mm screw (to fix the board in the Levitator base) Electronic parts: For the Board: 1 x 12V 800mA power supply. 1 x Arduino nano nano board 2 x 15 pin female single row straight header (2.54mm pitch) 1 x DC power jack 5.5-2.1mm, 8mm Diameter: power jack 2 x 3mm LED, the color of your choice. 2 x 330ohms 1/4W resistance. 1 x 470uF polarized capacitor 1 x 10-100nF capacitor 1 x IRL540 mosfet transistor or equivalent (need to be TTL "compatible"). 1 x 1N4148 diode or equivalent 3 x 2 pin JST male header 2mm pitch 3 x 2 pin JST female header 2mm pitch + crimps 2 x 2 pin JST male header 2.54mm pitch 2 x s pin JST female header 2.54mm pitch 1 x 3 pin JST male header 2.54mm pitch 1 x 3 pin JST female header 2.54mmpitch + crimps For the Coil/Sensor: 1 x SS495A Radiometric linear hall effect sensor (or equivalent) ~140m CU wire Ø 0.28mm 5 x ~40cm 24-26 AWG wires to connect the coil and sensor to the board. For the Levitating object: Some very strong neodyme permanent magnet (N30 N42 N50) You'll need one or more for the levitating object and you need one or more to put on top of the coil To Add bluetooth capability: 1 x HC06 or compatible bluetooth module HC06 module 1 x 4 pin female single row straight header (2.54mm pitch) 1 x Mini slide switch SS12F15G
