Yes, on the Internet the slayer exciter circuit (SEC) was supposed to have been created by a Dr.Stiffler. The circuit was around long before Dr. Stiffler claimed to invent it. It is like a flyback or ignition coil driver with one transistor, only it uses an aircore secondary with a primary like a tesla coil. The one on instructables is pretty weak. Look for a schematic that uses a 2n3055 which handles much more current. You only need 1 diode though, and for size and efficiency, it is important to have a tertiary coil connected to the secondary. Remember to tune the primary to the secondary and load (uv tube) and have it run off a small 12 volt battery. I'm working on one now it works very well, I still need to tune it more and add a topload. I can't wait till I can hike it through major woods and set it up with a white sheet!
