Freely Levitating Lamp

Introduction: Freely Levitating Lamp

It looks stunning and one must think that this project is overly
complicated. If one would start completely from scratch this would be the case but most of the components can be purchased assembled. Everything is based on induction and more or less plug and play when bought assembled.
Before you build this you have to think about what you want to have floating in the air because there are different levitation pads out there. I have seen some which can even lift 500g. Just make sure to purchase on which allows for an input voltage of 12V.

Here are the stl-files for this project.

Supplies

Tools:

  • Soldering iron

Tools (optional):

  • 3D printer

Step 1: Assemble and Check Your Levitation Pad

As mentioned before you can buy the pad already assembled. But if you do not value your time and want to save ~5$ you can assemble it yourself. This is however a little tricky and I would not generally recommend it.

When you have assembled your pad or unboxed it check if it works or not. The first time placing the magnet on the right spot can be a little bit tricky. However you will feel when it is on the right spot because the magnet will not “bounce” around.

Step 2: Connect the Induction Coil to Your Levitation Pad

Connect the coil of the LED to the same barrel jack as the levitation pad. Make absolutely sure to check with a multimeter that you connect 5V with 5V and G with G. If not you will damage the circuit.

You can now glue the small circuit of the LED on the PCB of the levitation pad and gently bend the wires of the coil so that you can lay the large coil around the small coils of the pad.

Attention:

Because
we are joining two inductive fields with each other you need to have the large coil facing a specific way. Otherwise the magnet will not stay in place. So test that it is orientated correctly before fixing anything in place!

When you are sure the orientation is correct, either:

  • glue the coil on top of the pad or,
  • glue the printed circle on top of the pad and on the circle the coil.

I have chosen the first option because I like the look of the PCB’s and coils.

Step 3: Assembling the 3D Prints

Print these files from my Thingiverse and put the magnets in the case. Also glue the coil and the LED’s in their case (make sure that both are in the center. Lastly glue the case with the magnets on the bottom of the LED case.

To assemble the base case just put the levitating platform inside it and line up the power connector with the hole made for it. Optionally you can glue the three legs on the bottom of the case so that it cannot move anymore. You do not really need to print the case. I modeled and printed it out but I like the look of the bare PCB and coils better.

Step 4: Enjoy Your Work

Finally!
It is time to place your new lamp somewhere and enjoy your work!
