Not very scientific at this point but I must point out the reactance thing does work with tiny generators, I tried it with a toy sized hobby PMM generator motor. The frequency you need to watch for as that is how X capacitor is calculated. So if your generator operates at an odd frequency your going to have to calculate some new capacitor value. Or it wont operate as intended.

How ever I have offered some alternatives to get more or less the same results and same current inputs with just a few extra parts and a spark gap stage for those who fear the reactance instead of using the x cap setup.

The current limiter as per ohms law x= 1/2*3.14fc
I = v/x

So 60 hertz with around 1uf gives us about 40 ma of current only!

Help me out with my math please:

V = 110 (Volts)
F = 60 (Hertz)
I = 0.04 (Amps)

X = V / I = 110 / 0.04 = 2750 (Ohms) = (PI  * F * C) / 2 = (PI * 60 * 0.000001) / 2

That doesn't compute.  What have got wrong here?

I was shooting for an equation solving for C, so I'd have that handy as a starting place for which capacitor to use.

to be honest I just use the math from this site as a basic reference and what I don't get I just punch in online calculators to help me out.

https://circuitdigest.com/electronic-circuits/transformerless-power-supply

So if its not 40ma then what is it? from the chart on that site and all the calculations I run in the calculator for X I find online.  It is indeed going to be a small value what ever it may be. But if there is an error in calculation would be nice to know the specifics.
Thanks

High Efficiency Lamp Driver Back EMF Version.

After some criticism over some of my reactive circuits,  I quickly put together this working demonstration that we can do the same thing via other methods, its all about limiting the current to its lowest value we need so we don't have to pay much. the previous x reactance method was just one of the many.

Here I use a low voltage square wave generator that operates at around 5 volts. This triggers a base resistor of NPN transistor to switch my 9 volts battery into a home built 1.9 ohm air core coil, quicky wounded with telephone cable. About 300 feet of it.

We feed the high voltage backEMF with the help of diodes Bedini style and quickly charge a 10uf cap to 100 volts with very little current thanks to the sharp low 10% duty cycle holding back much of the current from leaving that 9 volt battery but in return produce loads of back emf for quick charging and discharging of 10uf capacitor at 100 volts thanks to the SCR neon capacitor dump. We store this charge into a set of 12 volt supercapacitors this gives us steady dc in return enough to run that little high frequency inverter and drive the lamp just fine at its full lumens normally needing 15 watts at 60 hertz AC! It's clear here this little 9 volts can't produce "15" watts on it's own without the help of some additional systems, pulsing, electrets, super caps, high frequency etc... thanks to running the circuit mostly as an open loop.

It's a more complicated circuit but it further proves the concept. What you can do with very little current if you know how to utilize it.

The formula to calculate the capacitor size is as follows:

C = I / (2 * Pi * V * F)

Where V is the mains voltage and F is the mains frequency.  The current I is the level being dropped down to.

So for a U.S. application needing 40ma we get:

C = 0.04 / (2 * Pi * 120 * 60)  =  0.88uF

That works.  So yeah, keep that formula in your head if you need to throw something together in a pinch.

Yes, another good one.  Thanks again Joel.   Not quite as portable with the large spool of wire, but it certainly gets the job done.

Yeah that was my point, more complicated not as portable but does the "job" for those who want to keep away from reactance.

Personally, with millions and millions of those little transformerless phone/tablet/USB chargers doing the same thing, I think the reactance horse has already left the barn.

And I was like ok this guy is thinking and complaining about safety and liability? Meanwhile I'm thinking of all the Tesla Coil builders and backEMF and all that, Double standards lol. These are high voltage PSU units that plug into the mains and can kill and really do harm to the electrical company if one does not know what they are doing with Tesla coils. Meanwhile the site has its own Tesla section to talk about and that's 100% fine lol. I can read between the lines here and understand why some poo poo all over it unfortunately. So I offered a quick solution to those who complain at the reactance. Using Back EMF and a big coil instead.

Image below is only response to your new topic at overunity research forum.
One of several topics you started shortly after joining!

Here in its entirety the comment from a forum which was already threatened by a lawsuit
do to A members post !

Action had to be taken to keep the forum open !

Here things are equally as vulnerable!

You have many open topics at above forum untouched!
Sorry if another persons liability offends you.
Perhaps  start a blog ?

Btw
I am still waiting to hear back from Peter at Forum
As mentioned he works away from home weeks at a time .

Sincerely
Chet
Ps
Edit for comment below!
These few open source forums are precious to long term membership
As well they are vulnerable ( here also lawsuit threats modify forum
Into Compliance with laws and owners personal liabilities !

However
Even at overunity research your post has not been deleted !

I think this guy is just on a power trip and trying to somehow scare and threaten this site as well! I get it guy! You can't please everyone. You don't like it you don't agree with it and most don't understand it. I'm sorry about that. So I moved to another community and why must you follow me here in another place all together and keep bringing this up like your doing us somehow a good Samaritan move to warn everyone about my posts and that this host and every other hosts should take action because somehow you have an issue with it and still do as obviously you don't understand and insist on some talking points you keep bringing up as the reason of your logic,  that don't make any sense to me! Anyways I don't want to argue with you. That is why I came here to share my circuits in another community where they may be better appreciated and understood.

Still odd your pushing the whole "Safety" thing and doing so at it, as going into other forms and sites to warn people? With these screenshots and such! Don't you have any other things better to do?

If for some strange reason the admin team of this site deletes my posts what good does that do to you personally at the end? just wondering.

Joel,

I had just about decided to not reply to anymore of your posts.  But you keep claiming that no one understands your circuit.  That is absolutely NOT true.  Most of us on these forums have worked in electronics for many many years.  I made a very good living repairing highly complex industrial machine tools.  I have worked in electronics for over 60 years.  I highly try to encourage others to also explore and learn about electronics.  But I also try to caution people when they are doing something that may get them into trouble.  Legal action was in fact taken against OUR in the past for something posted by one of the members.  Chet is not making that up.

I don't want to bash you in any way because I admire your enthusiasm.  But your ignorance about electronics is clearly evident in some of the posts you have made.  Ignorance does NOT mean stupidity.  Ignorance just means you have more to learn.  I want to encourage you to look for some good online electronic classes and start studying.  Youtube videos are made many times by people that don't know what they are talking about so avoid trying to get an education that way.

As an example of you not understanding deeper electronics I saw in your last video that you said that circuit used back EMF and avoided reactance.  Not true at all.  The reactance of the coil is what gave you the inductive kickback that you are harvesting.  And that basic circuit of powering a coil and then collecting the inductive kickback has been around for probably over 75 years or more.  The little tiny boost modules you can buy on Ebay work in the exact same way.  They use a smaller coil and just fire it more often to reach the higher voltages.  And they have a feed-back circuit to adjust the pulses so as to keep the output voltage steady under changing load conditions.

Respectfully,
Carroll

Now your just mixing my words lol first of all everyone knows by avoiding reactance I mean a circuit that uses mains and such circuit as ppl where complaining about that issue specific "how dare I connect a reactance circuit to the grid".., We can't avoid reactance in a coil I'm not stupid,  why do you think I make a point of specify that it's 1.9 ohms! yeah so stop complaining and making things up please.

1.9 ohms is NOT the reactance.  1.9 ohms is the resistance.  The reactance is determined by the inductance of the coil and the applied frequency.  It's pretty obvious you aren't interested in learning real electronics so good luck with your Youtube education.

Bye

LOL you keep saying I'm wrong, inductance has resistance lol you can't have an inductor with no resistance, A wire has resistance and is considered an inductance.

Look, This is getting a little annoying, Being followed around by these 2 users here that keep nagging on my circuit and apparent lack of understanding in electronics,

I mean if these various FE and Over-Unity community forums groups etc. Where real life communities one would say this would be considered stalking behavior, I think they call it "Trolling" in the digital world. It's just getting a little wired that those two are so hung up that they have to follow me on every online community I got to post these devices and nag or as they say "point out". Enough please.

If IM apparently so ignorant with my circuits and understanding of basic electronics why don't you stop wasting your big brain efforts on bashing and put downs and instead come up with something much better as to what I got going here. 40ma in and 15 watts out this works. The last circuit I did on the fly in one hour to prove a point without following any schematic as I know what I'm doing! And it shows the devices operate! , But everything has room for improvements so again if you two are so much smarter and have been in the electronic industry as expert for years lets see what you can come up with in one hour that works better. Heck if you do come up with something, Congrats its everyone's benefits if you tell us how it operates. Man kind needs this kind of thing right now. Even better if you two are that much smarter how about working on suggestions on how to make what I have here work even better!
