Make This Fun Electromagnetic Dancer Box


Make this super cute Boogie Box with Arduino. via instructables

The BOOGIE BOX is an interactive reprogrammable thing that can make almost anything dance and is fun to play with! You can build your own dancers and choreograph them to dance to your favourite tunes. You can create anything! Just add the magnetic feet and the possibilities are limitless.


Step 1: Electromagnetism Explained

Wonder how it works?

The basic principle that makes the Bogie Box an interactive dance floor is the grid of coils underneath its surface. There are 4 rows of 5 coils all individually actuated by an Arduino. It runs on 12V DC so it is a safe machine to play with.

Principle of Electromagnetism

A coil that we run current through turns into a magnet. Now, if we wind a lot of wire on an iron core and put current through it, the magnet will be stronger because the iron core is a good conductor for the magnetic flux.

If we now put a permanent magnet next to the coil we will notice that the two magnets interact with each other. Based on this simple principle of electromagnetics I have built the Boogie Box by arranging lots of electromagnets in a grid. Then all we need is a permanent magnet which we can make move in any direction alongside the grid.

Step 2: Tools and Materials

This project took me exactly five days from start to finish. I imagine now when all the techniques are available to your disposal, you will be able to finish it a lot quicker. Don’t forget to share with me your results in the comments.

Tools needed:

Laser cutter
3D printer
Milling machine
Soldering iron + fume extractor
Crafting knife
Hot glue

Materials for the circuitry:

Arduino UNO
Prototyping board or a machine to fabricate your own PCB design
5 x LV8548MC H-Bridge
5 x 0.47 uF capacitor
Connector pins
0.5 kg 0.224 mm enamelled copper wire
LED strip
ON//OFF switch

Materials for the case:

5mm plywood sheet – inside frame
3mm acrylic sheet – outside enclosure
20 x M6 by 60mm bolts and nuts
4 x M5 by 80mm bolts and nuts
Acrylic glue and brushes
