A magnetic hover board might seem like something out of science fiction, but you can make one, although it will only work under certain conditions. The hover board needs to be over a metallic surface in order for the magnets to work properly and start the electromagnetic repulsion effect. It’s also advisable that you don’t try and ride the hover board, as the ride will be very unstable.
Remove the wheels and axles from the skateboard using a screwdriver, then set the axles and wheels aside to replace later or use in other projects.
Glue the magnets to the bottom of the short deck skateboard using a hot glue gun, taking care to center the magnets and space them evenly along the bottom of the skateboard.
Cut two 12-inch lengths of wire. Solder one end of one piece to the positive terminal of a 9-volt battery and the other end of the piece to the positive terminal of one of the rocker switches – heat the soldering iron, hold the wire against the terminal, and use the hot soldering iron to melt the solder to bond the wire to the terminal. Solder one end of another piece of wire to the negative battery terminal, then solder the other end to the negative terminal of the rocker switch. Repeat with the other three batteries and rocker switches, cutting two lengths of wire for each battery and switch.
Hot glue each of the batteries and switches to the top of the skateboard, placing them close to each of the magnets. Open the contact points of each of the rocker switches -- that is, ensure the switches are in the off position.
Cut a length of wire long enough to reach from one of the switches to one of the magnets. Solder one end of the wire to the positive terminal of one of the batteries, and the other end to one of the magnets. Repeat the process for each of the other switches and magnets.
Check all the solder connections to ensure they’re tight and you have no loose connections; this is especially important if you’re new to soldering.
Place the hover board on a metal surface. Switch each of the rocker switches on, and in a few seconds the board will hover a few millimeters above the metal surface.
