@ kazm

What works best with my toroid turns is a pair of mpsa06 transistors with resistor set at 7K ohms. But this does not seem to provide as much power as you seemed to be getting when you were charging the capacitor in your video. I can get a little more power by reducing the resistance a bit more, but then the transistors get very hot. How many watts is the filament bulb you were using in video?

it's a standard 7w night light bulb, i'll give the mpsa06's a go tonight Concerning the output i'd wager you're seeing less because you don't have that many turns on the toroid, mine has about 400. Also, the ratio of L1 and L2 is important. At some point I'd like to figure out a calculation for this, but at the moment all I do for my L2's is add more turns than I think I'll need, then remove a few at a time while observing performance until I hit the sweet spot, which is where you start seeing the wireless effects, I have my AV plugs sitting nearby and when I start to see them light up I know i've got it.

UPDATE: I tested out the mpsa06's, for pure light output they don't match the 2n2222's, but they're about 90% and they are able to run with more resistance and therefore less amp draw. In my #2 video I showed how the fluoro would light only up until 1k, then it goes out. The mpsa06's will run up to about 80k, i'm using a 100k pot and it's acting like a very effective dimmer. At 10k though the light is 90% of the 2n2222 output, and the amp draw is cut in half. Same story for the LED bulbs, it's close but not quite as bright. The 2n2222's get an extra boost of light when I added a 470pf cap across the collector and emitter, it's a very noticeable difference. However the mpsa06's don't seem to respond to having a capacitor there, at least within the ranges i tried (from 68pf-470pf). The mpsa06's seem more stable and predictable in general, less variation to their behavior. with the filament setup, if i connect directly to the bulb it continuously lights up, but not so with the cap in between, the cap isn't filling as quickly. I also picked up some mpsa05's to see if they acted differently but they match the 06's behavior.

The following link is the test fixture for testing my replication of kazm toroid circuit for lighting filament bulbs. My capacitor is only half of his capacitance so it should charge up 4 times quicker to a given voltage and hold 1/4 the energy when at the same voltage. The neons are a safety feature to limit the capacitor voltage to 240 volts so it will not blow up.

The capacitor will charge to 140 volts in about 10 seconds. At this voltage there is enough energy stored to flash the 7 watt bulb to about the same brightness as in his video.

I was unable to get 2N2222 transistors to work well with the turns on my toroid. But, the MPSA06 transistors seem to be producing about the same power.

EDIT: My circuit may not be as powerful as kazm. He was able to get bright flash with 3 second charge. To get the same kind of flash, I need to charge for about 10 seconds (to 140 volts).

I don't if or where this has been discussed before or if it helps, but there's a wikipedia page on the 2n2222 that claims the following in regards to the negative resistance "feature":

Not all 2N2222 devices will exhibit this behavior since it is a side effect of certain transistor physical architectures.

When I first looked at the slayer007-k1zm toroid circuit I thought both electrodes of neon were glowing and thus it was producing AC. However, I noticed that actually only one electrode is glowing on neon and thus the output is pulsed DC.

I'm not using the toroid setup but with mine both sides do light up.

In my videos you may have noticed when I don't have a load on the system the meter will flash between AC and DC settings.
Even when it's set to just DC the meter will flash between AC and DC.
Holding a led go back to your battery the led should light eather way off eather battery post.

When I tried parallel transistors both elements of the neon lit up so output was AC. Why sometimes it is AC and sometimes not I do not understand. I do not think it is the number of transistors. More likely it is how the wires are laying on the bench (how the circuit is capacitively coupling).

In this video I just wanted to see how big a load I could put on it running it off the cell phone charger.

Quick question

Slayer I was wondering if you posted the circuit for that cause I want to give that a shot and compare it to the little rf circuit I did from the radio shack mims notebook "basic semiconductor circuits".I felt good about the circuit but it didn't have much in the way of wireless and wondered if a larger coil would work so I wound a 2 and a half inch pvc pipe but had equal results and it does have good single wire action. Anyone gotten more output than input yet? thanks for puttin up with me you guys are awesome and I have really enjoyed these experiments area46241

Hello Area46241

Yes there is a circuit for it on page 10 post#314.
The capacitors are just part of the recovery circuit and are not needed for the light to work.

Hmm I wonder how many halo lights would light up if you threaded the tube though them and stacked them on top of each other? Great vid as always

I did a test to see if I could get things going with a smaller (+ more easily obtained and less noisy) toroid, and got similar results using a 1 inch toroid:

Excellent video Kazm.

One of my commenters asked me to upscale this for higher voltage.
If you want to run this on higher voltage you just need to make a bigger L2 coil.
I allready had a bigger L1 coil I made this one is 16" long by 3.25".
So I just doubled my L2 coil to 18 turns to match the higher voltage.

Running it off 12v the current draw is close to the same but it does put out more power.
It still needs to be tuned better.And I havent looked at the BEMF yet.
But boy I think this thing is going to have to be put in a cage.

How to increase power of slayer007 exciter circuit. Transistors do not get hot but 20 ohm resistor does.

EDIT: Will also run from cell phone charger.

[xee2]

Two transistor slayer007 circuit voltage is about 1400 volts. Using cell phone charger without 10 ohm resistor produces about 1200 volts.
