Description: These transformers are capable of creating spark gaps up to about half-an-inch. They work really well as an ignition source for things like potato cannons, they also make the official sound of the mad scientist. The sparks that are generated sound a lot like a taser and you should take that sound as a warning to take extreme care when the unit is powered.

To throw sparks, simply secure the two grey wires to electrodes spaced no more than half-an-inch apart and connect the red and white leads to a 5V source. Be warned, these transformers draw about 3A so your power supply will need to be somewhat robust.

Note: Please do not use these to shock people or animals. Seriously, that isn't cool. Actually, be extremely careful with these as they can seriously hurt you.
