some other transistors that work...

2SC6081, KSD1273 seem to work similar to the fuji camera transistors with slight changes in resistance or capacitance. 2n4401, and even 2n2222 work if you drop the resistance further, but they seem to have a greater power draw and the light cuts out sooner.

[twofortheroad]

Just thought I should mention that I have tried many different transistors and they all work. You just have to match the resistance and capacitance to the transistors gain and I'm not using a bifilar coil. Just the resistor and cap. I have gone to transistors of the TO-220 package, so i can use a heatsink with them. While experimenting I found it necessary because occasionally I would get too much feedback and pull 5-10 amps at 10-12 volts and smoke the transistors. With the heatsink attached it allows me to pull that much power for short periods without damaging the transistor.

Just to mention a few BUL128A, TIP120 (a darlington), MJE3055T (the TO-220 variant of 2N3055), 2N3904, 2N2222A, 2N4401. I have gotten all of these and others to work for over a minute with only a 1000uf cap. The trick is to tune the circuit till it runs on less than 1mA while connected to the battery. The only difference I've notice between transistors is some will strobe at under 1mA and others provide continuous light.

I've also added a 2 stage Villard cascade voltage multiplier to the output of the transformer to increase brightness of the cfl and it also increases the frequency of output so less strobing. It doesn't seem to affect the duration of the lighting of the cfl as I had hoped, but it's effect is still beneficial to the circuit.

@all,
Have any of you made your own transformer that does the same thing?
And have you tried a transistor in place of the diodes with self bias?
Just asking here. I'm going to try a ferrite loopstick from an old am radio. and did anybody measure what frequency the device is running at?.
Just a few things.

@all

I know of some transistor that would work nicely on those , Next time you see a PC printer pick it up , there is a pair of transistor to drive the motor , in my experiences they are very similar to the transistor use in the fuji.

Transformer...

John,

I built several trifilar "transformers" to try and duplicate the effect, but none worked. They all were based off a R33 ferrite rod with one high voltage, higher resistance winding and two low resistance windings. The core I tried measures about 1/4" diameter and I made one layer of 30 gauge about 2" long overlapped with two 8-16 turn low resistance windings. When that didn't work, I tried one layer of 36 gauge with the same low resistance coils on top, and still nothing. The low resistance coils would work as a simple joule thief, but I couldn't get the "joule ringer" effect.

I've also been trying to build an output transformer to step down the output voltage for battery charging and other applications, but no luck so far. The current/voltage out of this thing behaves really strangely.

Finally the sweet smell of success That is after blowing out my Fuji transistor after about a 1 or 2 second run. My Fuji AA camera had a D2607 transistor. It wasn't working but after some playing around and reseating the transistor on my board it fired up the 14 watt CFL quite bright but instead of using a cap on that try (after reseating ) I was using a 12 volt Ni-cad pack at about 13.5 volts. The magic smoke appeared in about 1 second. I tried a couple 2n2222a but no luck. Next up a IRF640N - I'll try anything. I'm sure this is not a great choice but success! It was dimmer than with the Fuji transistor but this one lasted and lasted. I got 4 minutes and 35 seconds on a 40,000 uf cap charged to 13.55 volts. I used a good 1N4937 diode paralled with a 2.0 Megohm resistor across the bifilar. The bifilar BTW is an oddity itself as it's one wrapping on a roughly 8" diameter toroid made of copper tubing (the type used for coolers which is 1/4" inside diameter) and the tubing is about 15 turns making an 8" diameter toroid outside with inside about 6" diameter. Light went out when the cap reached 3.3 volts on this one
I also ran the test with one 8200 uf cap and that lasted 47 seconds with a starting charge of 13.3 volts.
Another test with a 31,000 uf cap with a starting charge of 12.15 volts lasted 3 minutes 25 seconds. All the caps of have are quite old and have kicked around a lot with a fair bit of abuse I'd say.
I had some fairly odd results using a 10,000 uf cap charged to 13.5 volts. In both cases it blew out my IRF640N. It had less charge than the 40,000 uf cap so I don't know what happened there.
Fascinating circuit. I look forward to trying some of the other transistors mentioned here and hope I can find an affordable transistor that can run this as bright as the short lived Fuji. I think the Fuji would have lasted if I had started with the cap only and used a lower voltage. Did any one else have a D2607 out of a Fuji camera?

One other note when I put this on the scope there are some serious sharp high voltage spikes showing up. I forget the frequency or voltage but I was having to use 5 volt divisions with a 100x probe.

Maybe..

The wire might get some where but I wouldn't go out of your way unless it is what you want to do. It will get tested either way. It is on my list as I start to build these coils.

I will be ordering a few rolls of wire because I am tired of using rewraped magnet wire. Twice the job to build a coil. One to unwrap it and another to wrap it back in a new style. lol I have been using ground plane wire from old TV's and monitors. I had an old professional monitor that used the bnc connectors and it was chock full of goodies like 12 2n2222a's on one little board. So I got enough to play with in the lines of components. The ground plane was really nice copper magnet wire good purity. But I don't have enough to make a huge coil.

As I learn how to wrap these coils I can try the aluminum wire as well. I am betting the effect will be in the wire because of the capacitance is in between the wraps. One question do they make 26-28 gauge coated aluminum wire?

One question before I start. My first coil in the bifilar realm was neat. I mean I was strict on wire placement. I wrapped the first layer in tape because it was easier to put on the next layer and instead of winding back and forth I wound it organized one way through the spool back to the other side and continued to wrap in the same direction. The wire turned out to cross the coil in such a way that it cut across the coil wires, which should not interfere with the field of the coil. Is this a good idea to do or should I just be sloppy and pile the winds on? Sometimes I think to much before I do something rofl...

coated aluminum wire

I don't know about coated aluminum wire. I had U-haul rewire the tail and brake
lights in my cab years ago and they used aluminum wire ( don't know why?) I
think it must have been insulated. The guy who used aluminum wire for the Newman motor, said he coated it with rust paint. Hope this helps.

P.S Ground plane that's a term I haven't heard in a long time. Old CB days!

Pleasure to see you messaging. I too am gonna try my hand at a custom transformer. We got the ohm measurements and should be able to wind a duplicate of the flash camera transformer. one is an off center tap and the other is very small (input) wrap. It shouldn't be hard to do this. I am gonna do it on the same am radio ferrite rod. I am still gonna try to keep the winding style very neat and cross over the first wrap and continue the wind in the same direction. I think it might be important to keep a neat wind. For the transformer I am gonna use up the rest of my ground loop wire. It is about 26 gauge in my estimate. Do you think they used different gauged wires in the camera transformers?

I also want to try a mini version of the Tesla transformer that he used to get Ultra high voltages from, the one in an oil bath. The transformer he used was a little complicated but I think I understand it now enough to make one. The transformer is the one from his book on google:

The Nikola Tesla Treasury - Google Books

After page 67 he starts with the alternating currents with very high frequency stuff and how it is a natural for light production. This is what we are doing right? It might be better to check his experience first when going down this road. His words resonant with what we are seeing.

Page 88 is where I am stuck at. That transformer looks familiar. Although it is quite different in what most are using here. It looks to me to be a split bifilar primary with no tap and a secondary wrapped over each bifilar coil half. This secondary can be center tapped as well. Of course with such small gauge of wire, oil is the only recourse to keep it cool and increase the insulation.

Keep in mind that the transformer on page 88 is only the rudimentary version. The full version would be here:

"Experiments with Alternate Currents of High Potential and High Frequency"

Figure 3 is the transformer after modifications he made to improve the design.

I will post this for Jbignes5 it as the fuji AA transformer spec with wire gauge .

@ All,
Thank you for your reply in answering some of this. The transistor is a special one in that it's gain is very important at that voltage level. if you are going to try and make this I suggest that you build a triple Darlington using a 2n4401.

The SOA curve is very important in second emitter breakdown with this device. Just look at the curves at DC find the voltage and see if your out of the window. It's not so much that the transformer is anything special except it must work at a low voltage of 1.5 volts, not much.

Have any of you tried to charge it like a CapTret with a little feedback. I'm thinking your trying to make the eternal light for outside which can be done. I do not have any space to post a solar application here unless I use my home pages to do so. I will see what I can do to give you the circuits. I have run solar lights with capacitors all night long with some of these circuits, but a 50watt CFL would be much better. I have also done this with Monopole motors charging big batteries. I will see what I can do about the circuits for this.

Thank you for the circuit mk1.

Thanks for the circuit and winding ratio's. That might help a bit to figure this out.

I am still with the thought that this is similar to the Tesla transformer but without the quasi bifilar in the primary. I am still under the impression that Tesla was converting the energy type into the electric field and then putting that through the transformer. His conversion process was relatively straight forward by charging a capacitor then discharging it through the transformer which would amplify it even more. Since the discharge from the capacitor is much different then a normal high current discharge it has other effects that seem to mimic static electricity. Tesla did a lot of work with statics as well and he was totally convinced that it was what ran all of nature and matter.

The thing with Tesla was that he didn't use capacitors like we see them today. He used a form of improved laden jar and that might be the connection since electrolytic caps are more close to that format.

@John_Bedini

Could you show the triple Darlington transistor or is that the whole package of the 2n4401. I am not so familiar with that transistor. *edit* Nevermind I looked it up.. Hmmm interesting thought there.

I have done extensive tests on the captret and have concluded that yes it is an interesting effect but I fail to see the direction you are going with that. Maybe a quick diagram would suffice to steer me in the right direction.

Thanks again for dropping by and commenting on this. You have seemed to master this before we knew what this even was. It's a big help to talk to you directly. Thank you again.

[dragon]

I posted a similar circuit some posts back using Dr. Stifflers fast charging cap circuit. ( similar to the captret arrangement ). I haven't had time to try it as yet but I'll be able to get back to playing with the JT Ringer soon. It's been a busy week ....

John B,
we are very interested in your ckt's and would traverse the "bad-lands" to replicate them. we hope they let you share... we have the basic SG trifiler self oscillating within this setup in place of the diodes but can not get it stable. choosing the right transistors is another talent we'll have to add to our long list of studies.

This circuit configuration seems to work slightly better than having the capacitor and resistor in parallel.
