Effects of Recirculating BEMF to Coil

[rave154]

quick update

a quick update,

excscuse my typing as i have wires ande ttest leads allllll over the place here

i have just put together a small bedini circuit using 12V, charging a 220uF 400V cap...

as the bedini is running i have connected the cap to be not only the output of the bedini but at the same time the coil INPUT to gotolucs circuit..

as its running the cap is holding a steady 70VDC and also the gotoluc circuit is performing as normal...ie..9V powering the 555 half of the circuit, " input bulb" is barely even glowing if at all..output bulb is 30-40% bright.

ok, just twiddled the frequency & duty of the GOTLUC circuit while running from the bedini CAP, and now the cap is holding 130VDC !!!!! witrh input bulb barely glowing ( if at all ), output bulb is usual 40% bright or so, bedini circuit is drawing about 135mA, note that i have not tuned the bedini circuit at all...so its probably possible to get the amp draw down quite a lot..


interesting, as i was twiddling the frequency on the GOTLUC circuit, the bedini motor/rotor was responding by slowing down . speeding up, as was the voltage on the cap.. which is how i came to the point at which its holding 130VDC..

a lil help

Hi,

does anybody know of a way to arrange pots so as to give the effect of a single fine resolution pot with a span of maybe 200-300 ohms?

Hope you can help,

Ahimsa,

Hi David,

Maybe the simplest would be to use 4 pots of 47 Ohm value individually and all in series and place also a series 100 Ohm normal resistor with them. This way they add up to the range you need and each contribute about about 1/4 value of the total.

If you wish to use less pots then maybe start with a 220 Ohm resistor and place with it in series a parallel combination of a 330 Ohm resistor and a 1 kOhm pot.

(In all of the above combinations use only the wiper and one end of the pots to get a variable resistor from them.)

Many combinations are possible of course, you may find out now many, once you got the idea.

rgds, Gyula

Good suggestion Gyula

Thanks for helping David with this.

schematic so far

ok, attached is the schematic which is basically a grafting of gotolucs circuit with a standard bedini charging up the cap in gotolucs circuit. the cap is a 220uF, 5400VDC.

Great work and experiment ideas you have come up with David

I like it ... how does the intensity of the bulb compare if you only connect it to the Bedini output capacitor (without my circuit connected) compare to using my circuit powered by the Bedini output cap?

Thanks for testing and posting your results.

GOTO,

just caught your post, im tired like a rag doll from work......but that aint stoppin me on this thing....... i can smell the goods here......in a purely "entertaining" kind of a way of course.....lemme just try out your suggestions here....


bulb alone attachted to only bedini cap..probbaly about 60% bright with a standing voltage of 6.5V on the meter....interesting huh!!!!!

ie....a 20% increase in brightness....or so...BUT.......only 6 volts left over in the cap after the bulb has takenb its share....compared to the total circuit which has trhe bulb at 40% bright.....with 110-130 volts spare

the Q is begging......with so many volts to spare......why is the buld only 40% bright with 130 volts left over...........why not 100% bright with say......i dunno.... 20V left over??????

[rave154]

i might be wrong here.....but i keep thinking back to my tesla thread.....where i have the HV from the ignition coil....sparking to the two leads of the SAME bulb....and back to the neg of the ignition coil.......and its lit to about the same brightness..........something is lighting this bulb.....and its not "electrons" as in......." electron flow through wires"......... its something else......why is the bulb only 40% bright with 130V @ 220uF ..left over to spare??????? why not fully bright with nothing left over in the cap?????

olk,almost bedtime,

i should mention.....the reason i asked about a way to make a high resolution pot..is because this effect ( if you can call it that) if incredibly finiicky with regards to the setting of the pot that controls the frequency coming from the 555 circuit....... i had the bulb at maybe 25% brightness, with 70V spare in cap......and i barely breathed on the pot....and it suddenly went to 40% bright with 130 V spare in cap.......im thinking there is a VERY narrow frequency range......therefore i need a high resolution pot ( or equivelent there-of)......to scan through that range to find the peak

Ahimsa.....im off to bed to dream solutions..

Hi,
i have been thinking of driving gotolucs circuit using one of those sound-card function generators, i think my soundcard puts out about 1.4V as i recall......AC ... does anyone know how to connect this so it replaces the 555 circuit in my last schematic?... do ihave to drive a smaller transistor like a2n2222 from the function-gen....which then triggers the mosfet?...help appreciated..as the function gen will give me greatercontrol of the frequency...and thats what i need right now.

Thanks,

hi all.
Today I played around with gotoluc's circuit for some time. At first I used an array of 10 12v batteries to test everything. Works like it should. I observed up to 6x greater currents circulating through the output 10 Ohm resistor than is flowing through the negative line back to the battery array. If the output resistance is increased, the current flow through it decreases, but more of the current is converted into heat and the resistor gets hotter a lot faster. Anyway, then I tried to drive the coil with rectified and filtered AC current from a variac that is also powered through an isolation transformer. I observed the power consumption with a meter much like kill-a-watt. I used two 20w light bulbs instead of the resistors. The thing is that the meter showed about 50w of power consumption but those bulbs were not even at their max brightness, the input bulb was barely glowing and the output bulb was at half brightness. As the duty cycle was increased, the input bulb became brighter and the output bulb less bright as is should be, but the meter showed that also the power consumption increased. Any ideas why the meter showed such high power consumption? I mean at that power both of the bulbs should glow at max brightness. The actual power consumption was really greater, I calculated out the losses of variac and isolation transformer.

Great work David

I understand why you need sensitive pot control as just like you I have observed this also. You need real fine tuning capabilities.

The higher the voltage at the Bedini circuit cap is with the output bulb at its brightest on my circuit will be maximum efficiency. I would remove the bulb in series on the input side of my circuit since it causes some resistance therefor reducing the output bulbs intensity. Just use the Bedini output cap as a way to monitor my circuits efficiency. The higher the voltage at the Bedini cap for the brightest bulb on my circuit is what you're looking for. You will find my circuit works at best efficiency with high voltage (as high as 220vdc) and with very short duty cycles. There is also a frequency range that best meets the characteristics of the Inductor you are using.

Make sure you Bedini circuit cap is rated for 250v or more and I would consider a cap on the output of my circuit so you will be able to attach your volt meter across it and the bulb to get a real DC volt reading. This will help with the fine tuning.

Thanks for all your work and sharing

Refer to this post and attached information. This explains all that you are seeing and why:

This is not difficult to comprehend if one takes a little time and effort to understand it. PLEASE AT LEAST TRY! And if you don't understand something PLEASE ASK SOMEONE THAT KNOWS.

P = V x I

There are a number of folks STILL saying that they are having a hard time understanding why they are seeing the things they are seeing, and can anyone offer an explanation as to why. Well, that is what I set out to do, and I refer you folks again to the post and the attached pdf file. IT IS ALL THERE.

There have been no questions about the information, so either all are ignoring it, all don't want to learn, all have missed it, or all don't care and would prefer to go on not understanding. There is no excuse for not understanding these basic concepts.

Hi Jetijs,

I also tried this same method of measurement at the beginning and concluded that meters are not capable of measuring the consumed power correctly.

I have not yet found a way to measure

I think using batteries and Ohms law like I suggested above maybe the best route.

Hi .99

I don't think that all are ignoring your extremely well prepared document explaining what we are seeing, as not many have replicated the circuit. So I would assume that it has had an impact on some. However, you have to give some the liberty to experiment, examine the effect, read your document to come to the conclusion that, they accept this as an EE conventional explanation, which is fine and myself think that 95% chances are that it is correct but some like myself may not be 100% convinced.

Let me ask you, are you 100% sure without any dough that this is all that is happening in this circuit?

I know that you don't buy 100% of the established EE since you are interested in the TPU and they say this kind of thing is not possible.

If you read my posts, and you do! you know that I've been asking for help to find a way to measure the circuit not using conventional EE methods. Your help would be better applied in finding such a way then trying to convince others about conventional EE is the right way to look at this, since many don't completely buy conventional EE including yourself and I think you. I am open to proving this circuit has no desired effect but how do I prove it in an non conventional way.
