The circuitry for it is simple. One of the first things anyone who has built a joule thief will notice, is that the circuitry is very similar. The biggest difference is that the small transformer or inductor has been replaced with a primary/secondary tesla coil configuration, and that the feedback is capacitively coupled. (There is a good abount of capacitance between the 'top' of the coil, and ground.) There are many awesome thing these exciters can do! they can: ► WIRELESSLY Light up:neon lights!-----------------------------------------(several feet away) florescent tubes!----------------------------------(within about a foot) CFL's!-----------------------------------------------(within about a foot) EL wire---------------(it does not work well for me.

If anyone tries it, please tell me your results!) LED's!-----------------------------------------------(across the room if done right) and even small incandescent lights! -------(with an L3 coil) paper with pencil markings -------------------(before it catches fire!)► Burn and ignite:candles wood (pencils) human flesh (now my fingers smell burnt) paper ► Destroy:crappy / half dead LED's bacteria sensitive electronic equipment (phones, computers, SD cards, CD's, blu rays, flash drives) someone else's stuff ► Create:ion wind motors the coolest lantern or light on earth fires plasma cutter►Make following electronic equipment go crazy:calculators watches digital clocks and alarms devices with capacitive touchscreens (PlayStation VIVA, smartphones, feature phones, tablets) UHF remotes ► Transmit wacky sounds (loads of EMI) to:AM radio FM radio shortwave radio HAM radios possibly TV interferenceHere is how to make a my version of the more powerful exciter (These videos were made awhile after this intructable, so the only issue with it is thermal management.)

Please do not get the instructions in this video confused with the instructions for the later TO-92 one in the further steps. Different bias resistor values should be used for either of these 2 versons.Step 1: A rundown of my experimentationShow All ItemsI did modify the circuit a LOT before I was happy with the results. Sadly, I did not take pictures of my circuit on the breadboard.The first picture show first circuit. I could not get to work. The second picture shows my first working design. I chewed through many transistors, and it was not very stable, but it worked. In hopes for better performance and reliably, I tried a darlington pair. It put out about the same amount of power, but did not kill my transistors. I believe this is because it increased the gain and the feedback from L2 was enough to sustain the oscillation. I think this is because it did not latch up and pop my transistors.I realized after running the circuit for awhile that I wired it wrong on my breadboard but it worked anyway.

I decided to "fix" it, and ended up burning out my last 4401. From then on I had to resort to 2n3904's. This darlington pair test was inconclusive due to my mistake of not having the collector from the first transistor connected to anything. I learned that if it ain't broke, don't fix it :PI finally decided to revert to my original circuit, except this time with all 3 remaining 2N3904's all in parallel. (collector to collector, base to base, emitter to emitter.) This worked exceptionally well, and I haven't killed any transistors since then! Now, I even get plasma shooting out the end! If you decide to build this, use that configuration, but use more powerful transistors, like 2N2222's or 2N4401's. They can handle more current.Later on I then decided to use a MJE3055 transistor instead of the weak TO92 transistors, and started to get much better performance. I upped the voltage from 9V to 12V, and replaced the 1Mohm resistor for a 10K resistor. You can get the instructional details in the video.

I have now began work on a MOSFET version of the slayer exciter, and with 50V and a computer heatsink, I can achieve results that border a small SSTC!!! (Solid State Tesla Coil) Unfortunately the complexity of the circuit did increase, due to the need to drive the gate of the FET with buffer to allow fast switching. Luckily it is ultra stable when tuned correctly, and can deliver much more power with more supply voltage. I increased the size of the heatsink compared to what I used in the first slayer exciter video, and have active cooling fan giving some airflow. Now I can let it run indefinitely at 24V and beyond! Note: The topload is still critical, if it is too large, performance will decrease. Also I can draw up to 3 inch long, incredibly hot arcs, and get corona that is about an inch long!!! I have even managed to "burn out" a screwdriver from the inside-out! Where the shaft is encapsulated in clear plastic, the plastic began to experience dielectric breakdown and began to melt, and eventually the electricity burned a carbonized hole all the way through the plastic to my fingers, Ouch!
