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.
Fancy building one? Stick around and read this instructables to the end! I have made sure all steps are well documented and easy to follow and reproduce!
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.
Watch this video where I test the system while it is being built:
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.
