@AC

In case the site goes down again, I wanted to quickly say that I thank you for your  last post and links which I have gone to. Some of this stuff goes above my head but I will be studying the circuit you posted.

@all

Yesterday I took apart a microwave oven that we were going to throw out at the office. Hey I got a great looking transformer that has a primary, a secondary and there is also a third small coil between them with about 10 turns. I am wondering if I can use that coil as a field displacement coil. I want to test this tonight on the current one relay system to see if there is any change in production, etc. Will let you know.

PS: There is a .92uf 1200v cap in the microwave so it should have been pulsing real fast. The magnetron is really crazy also and there is really nothing much to it. Two small coils  inside the cover box then it goes to the magnetron. Incredible what we can do with waves.

@wattsup
An old microwave is a great place to scavange parts, the cap I use in my circuit is 0.95uF@2100volts from an older microwave oven--you don't want to know what these cost retail. Plus the transformer contains a large amount of fine and coarse guage wire, I usually strip the wire and wind them on better cores as the transformer is best suited to 60Hz and I am running considerably higher than that. I just use an angle grinder to cut off the ends of the transformer then drill one shallow hole on each end of the core so the transformer can rotate between two bolts in these holes like a large wire spool, then use a drill to wind the wire on an empty spool or your new core --- I can clear a microwave transformer of its wire in about 2 minutes per section---- thats a lot of wire.

How long can the lightbulb in your circuit last before it stops flashing (assuming no more input of energy other than charging the capacitors up in the very beginning)?

So you know..............

90% if not more of microwave oven caps are connected in parallel to a resistor (inside the cap casing, you typically cannot see it), typically greater than 1Mohm
this equates to current leakage (safety feature).

Take what you will from this information. And remember, ohms law and what this means for your large voltages.

@AC

Thanks for the heads up on the transformer but I really wanted to try this out on my current build under the Trial #3 diagram and used my 88uf 1200 volts cap on the output side, no second relay "yet". So I just removed the toroid and replaced it with this microwave transformer. Just pushed the on button for about 5 seconds and the system blew my 110 volts bulb immediately (yeh I had left that on by mistake) and voltage went up to 650 volts before I stopped it. What a scare. Holly crap. I have to understand what the hell is going on here. This is beginning to be some serious juice. Will have to measure voltage/amperage etc., but with so high a load. Maybe I can contact SM and borrow his bank of 10 lights. It must be lying around somewhere collecting dust. lol

Added:

@armagdn03

Yes I saw the resistor right off the cap going to the chassis ground. Also the transformer secondary had one side connected to the transformer armature as ground but I took this off to isolate the secondary before doing the above test. Don't worry I won't be doing any microwaving.

Added again:

OK I brought it up to 1280 volts, but I know now that the amperage is totally minimal. The 110 volts bulb I had was a small one the size of a golf ball rated at 7.5 watts. I put a regular bulb rated at 100 watts 120volts, started the system, no light and voltage was held around 3 volts with the load on. So no, it will not light the bulb.  But 1 now have 1200 volts power supply that I can use to send to some other coils. Still great. Will try by reversing the coils.

just to make sure you understood what I said, try hooking up an ohm meter to the terminals of your microwave oven cap, if it reads a resistance, then there could be problems. If it reads zero, you are good to go.

@ wattsup,

Was reading through the threads again an I noticed on your schematic your transformer appears to be backwards.Is it just drawn wrong or is that the way you have it? Maybe I'm wrong but i thought it is supposed to the other way around. I tried my setup both ways and when doing it the same way you have it I get lousy results ...cant charge a cap at all.

@am1ll3r

In Erfinder instructions, the choke goes to the primary (which is the 240V side) and the secondary is the working circuit (which is the 24v side). I have tried it both ways also and it works OK. Also tried it with two other transformers and it also works, but in all instances, you will need to play around with capacitor values to get the right toggling action on the first relay.

Also, you can try putting the capacitor connection that now goes to the blue wire going to the relay coil and choke side, to the other side of the choke going to the NC relay contact. This will give you the full inductance of both the relay coil and the choke, to charge the capacitor.

If you look at the diagram, the primary of the transformer is completely isolated since  both sides are connected to the two N/O terminals of the relay. All this circuit is basically doing is charging the cap and discharging it into the primary (or secondary if the other way around), plus it is cycling the power going to the relay to reset itself.

I have tried putting that cap at various other locations but cannot achieve the complete connection of the common terminal to the N/O terminal, This is the only way I have found this to work.

By the way, I am now working on the second relay connections which is much more trickier to do since there is no choke to increase the inductance. All we have is a relay, a diode and a cap. Plus the damn relay keeps hogging the juice as it is produced so it really has to be isolated until there is enough build-up to make it toggle. But a regular diode just let's the juice pass at a much lower voltage so the relay coil hogs it up again.

I have made it work in various ways but not to my satisfaction. I am sure I will need a zener diode rated at 10-12 volts as this would act like a solenoid, opening only when their is enough juice. I am concentrating my tests to try and recharge the source battery and see if the voltage off the battery will rise. That would be the icing on the cake. lol

For your set-up, you need to have more capacitors. Erfinders initial 47uf was a place to start but you need to tune your specific relay coil/choke inductance to capacitance in order to make that relay toggle to both the N/C and N/O terminals. Put a meter on the N/O side to see if you get any output off the relay, since it may be hard to see if the relay is clicking to fast. Also make sure your wires on the relay are well tightened since a few of them may heat up and get loose.

More fun to come.

He was referring to the primary as in the patent.
If you read the patent...

More fun to come.

I still have not figured out the working side but here is what is working for me...
My cap C2 will charge up to 50V in under 10 seconds. It can be tweaked but I'm going to need another transformer.
Looking for an old Microwave ;D

To figure out the working side is to..........well, solve your problem. A suggestion, or perhaps a proposal, figure out how the load affects the source, or perhaps the source the load. really what is the difference?

I have been following this thread closely guys, although I havent posted much. I had an idea the other night while I was toying with one of my monopole motors. I was thinking that I could use one of them to run as the load on the secondary. It is totally variable in amp draw from 25ma to 250ma or more. I know that this project is designed to learn as much as we can about Tesla basics which means using as little amount of solid state stuff as possible. However, the load can be anything, no?

Am I understanding it correctly that we want the secondary  (which is coupled to the load?) to oscillate  too? If so then this simple monopole would fit the bill quite well, and would allow some variations in tuning etc. AND your charging batteries on the back end of it too. It would be great to step up the voltage and then run the monopole off the secondary cap. I am still collecting parts and studying/learning the basics, I'd like to hear any comments?

Keep up the good work guys!

@Erfinder

Thanks for straightening us out. Granted I am like a kid with his first fire truck just rolling it all over the place. Also, there is this innate OUers' desire to always want to loop things back. Force of habit.

I have already noticed that the battery is going down very very slowly and am in the process of working out the second relay connections, but without a load it was hard to see if one is on the right track so I had been testing this with different light bulb wattage values from 7.5 to 100 watts, etc.

Consider that us novices have had a smidgen of time with this compared to yourself or others that have tried this. Blend this project with others that I am working on presently and the alloted time does also become a factor.

I remember when you said this Ozone Patent does not necessarily have to produce ozone, and that is what has stuck like Krazy Glue. (Oops no advertising allowed.lol)

I am surprised that my first relay is still holding out because I have seen many types of contact sparks being either orange (regular dc sparks), blue and a very plasmid green, with some ozone production to boot.

My microwave transformer is giving me up to 600 volts in about 5-6 seconds of the system on time which is just mind boggling. My present trials with a second relay is making it work but in a very erratic frequency and I am trying to work around this with only the allowed number of components you have indicated. I now think the second relay coil has to be in parallel to a load so the load would take the power down and reset the relay to re-charge the working capacitor. But there are so many variables possible and it will take time. I am usually doing modifications to my drawing first, then applying it to the setup so I do not lose track of what has been done. I am up to drawing number 18. lol

If Humbugger was still here, he would immediately say, "hey but again this is 600 volts of reactive power with no punch". Hmmmmmmmm.

Your indication of running a motor to run a generator has not fallen on deaf ears. I have plenty of dc motors with a wide range of voltage and amperage values and I can set this up rather quickly. I am thinking a small 90 volts 1 amp motor should do fine as a drive and use a 24 volts 20 amp motor as a generator.

Lastly, please note that while I am doing this project, it really has opened my eyes to so many other things that could be applied to other projects and I need to actually concentrate on one or two, but the temptation is so great. lol. But please know that just because we have not posted in several days, it does not mean we have abandoned.

If the purpose of this circuit is to produce currents of high frequency and potential then it should be designed as such. The large self-inductance L1 is the means to raise the potential but how would we raise the frequency?. The period of oscillation in a circuit is based on the values of L and C, inductance and capacitance so to get a high frequency we would want a small value for L and a small value for C. In the diagram below L1 is the High self-inductance, L2 is the low self-inductance so we have the means to raise the frequency . We would charge the high self-inductance through contacts 1 (NC-- normally closed) then open the contacts 1 to produce a high potential discharge through L2 to charge the capacitor. The diode ensures the capacitor does not dischchage back through L2 and L1 and is only needed if you want very slow switching speeds. Next we would need to form a circuit of low self-inductance and small capacitance to produce a high frequency, in order to do this we would need to disconnect L1 from the circuit by opening contacts 3 (NC) these would open just after contacts 1(NC) they would be sequential in operation.Next we would need to form the circuit of low self-inductance, we would do this by having the contacts of 1 swing over to the (NO) side and close the contacts 2, the circuit of C and L2 is now a circuit of low self-inductance and a charged capacitor which will oscillate at high frequency, this frequency based on the values of L2 and C. The High potential high frequency oscillations in L2 and C will be transfered to the secondaries of L2 raising the potential further yet. Thus on the secondaries we have currents of high frequency and potential. This circuit setup is not the same as Tesla's, I think it is the slow motion version of the process he was using but basically produces similar results. The contacts 1,2 and 3 are a single DPDT relay.
