I'm thrilled to unveil my new 3D printed Levitation device! How crazy is that? It's possible and actually not too difficult to make. I really had a lot of fun with this project and I am so happy with how it turned out. I hope you enjoy it! Stay tuned for more fun and random projects!

I put a lot of work into the video. It should explain everything so check it out too and thanks for watching!

Step 1: Materials

MOSFET IRFZ44N N-Channel (Jameco #669951)
Hall Effect Sensor A3144 Unipolar (Jameco #1718701)
4x AA Battery Holder Cover & Switch (Jameco #216187)
Neodymium Ring Magnets 9.5x1.5mm (Or any small strong magnet)
Magnet Wire AWG 30 (aka Enamel Wire)
Steel Screw 4x15mm Philips head
1K Resistor (Brown, Black, Red)
Mini breadboard 25 tie-points

Print the spool holders very slowly since the walls are thin.

Step 2: The Coil of Wire

Place the smaller spool holder inside the larger one and add the screw at the top.

I recommend creating a holder for the spool of wire to unravel from to prevent kinks in the wire. A few thick books and a pencil should do the trick.

Insert a few inches of the wire through the small hole closest to the center and wind the wire tightly and try not to overlap but some overlapping will still be ok.

When done winding, cut the wire but also leave a few inches and loop twice through the small outer hole.

Step 3: Breadboard Circuit

I designed this part so you don't need electronics experience or soldering for this step. Simple match exactly the image shown and in the video. Clip the ends off the resistor but keep both sides to use as shown.
The coil wire has an enamel coating that you need to scrape off both ends. Pay attention to the direction of the components since that is important. Make sure everything fits securely, use electrical tape to help hold in place if needed.

Step 4: Make It Levitate!

The hall sensor needs to be in the exact right position so I made the breadboard holder move around so you can tune it. Watch the video for reference. If the magnet wants to flip over, attach a piece of tape to the bottom.

Notes: Be careful and don't leave this unattended or on for more than a few minutes. The coil does get warm. Be safe and have fun!
