5v to 30,000v arc transformer module 
HIGH VOLTAGE - Create arcs with 5v !!

If you do not know what you are doing, then DO NOT BUY THIS!  Watch the above video to see why.  Using only 5v @ 2A, you can create some frightening arcs of electricity.  This module has a powerful internal step up transformer and internal oscillator within, and it is POWERFUL!  The manufacturer says not to keep the device arcing for more than a minute at a time, or else you can damage the device.  I don't suggest keeping it arching for more than 5 seconds. Just to prolong the life of the module.  All you need to do is apply 5v to the input end, and the output wires will arc.  I've tested it (In the video above) with 5v @ 1.25A, and I can arc to about slightly more than a centimetre.  It is fierce!  Dangerous as well.  You can seriously burn or shock yourself with this device, and I will not take responsibility if you do.  May that be your warning!  These are commonly used in bug zapper units.  There are four wires.  On the input end, there is a white and a red wire.  The red wire is your supply line (5v at 1A+), and the white wire is your DC ground line.  On the output side, there are two red wires.  This is the high voltage AC output line.  Watch the video for a full demonstration.  If you have any questions, PLEASE ask before you but this.  If you treat it well, it should last =)   Shipping cost is $2.80 for ground shipping from Canada. If you want it faster, contact me, and I'll give you shipping options.

Specification:
Supply Voltage: 3-5v
Current Consumption: 1-3A (The more amperage, the longer the arc)
