    You input would be helpful to me...thanks.

You might need to increase the value of the 330 ohm resistor, I used a 1K ohm resistor. By using this diode, you can make it less than 50% as long as the other resistor is bigger than 1K (or 330 ohms based on the original circuit).

      I'm not saying this is a good thing to do, it was just interesting how I was hammered by the moderator and my post was not even allowed into the forum...at least as I remember it was not allowed.

      Hi,

      I have try adding diode to pin 7 & 6 and the duty cycle about 80%, but the result not good to the battery, charging process very slow but you get higher voltage form the cap. Now I back to previous setup and better. So 50% duty cycle is work best for me.

        I cannot give much advice as I have not had much sucess with this yet.
        My battery size are 40AH and 70AH,
        Both battery above condition are very bad,

        I found interesting result today. Seem C20 method not always work for all battery condition. All depend the capacity and condition of the battery.

        Example: The good condition 100AH battery is good to charge with 4A-5Amp, that will stay cool and fully charge after 15-20 hours. If the battery condition not so good, you will see the battery getting warm after few hours with same size charger.

        Today, I have try charge with small setup (about 1 amp) and the battery stay cool and show the capacity increasing at first cycle. Now I'm going to the second cycle and will see the result.

          The pulse rise time is sharper / faster. John Bedini emphasises that its the speed of rise of the 'on' pulse which is important in terms of the radiant event, not what comes after.

          IMO there is no need to achieve any resonant condition. The battery resonant frequency is up in the Mhz, so any sub-resonant condition at the low frequency of the oscillator will be weak.

            Are you putting 4A - 5amp charge in with the Solid State?

            I have not had batteries get hot with the Bedini type chargers, unless.... I have done tiny batteries that should not have the voltage I was putting at them. I take this as a danger sign.

              Well, like I said, I didn't say it was necessarily better. But it I suppose it depends on what you are trying to do with the energy. If your goal was not to charge a battery, but to run a motor with it, then you'd probably want to transduce the radiant to 'normal' energy and the diode would allow that cap to charge to a higher voltage, or make discharging of it faster at a lower voltage.

              You must have meant a 20% duty cycle, no? 20% on, 80% off, right?

              I believe that you are right about different amount of amps to different batteries. That is why, bigger caps can charge better especially with bigger batteries. They can put out more amps on each pulse. He has said over and over, HV with a little current at the right time, no?

              So, what I said about the cap pulsing circuit seems right (and experimentally I've seen this trying to charge a small nickel metal hydride). HV does "sneak" through after the cap discharges until the 555 goes low again. The HV allowed to hit the battery and the current is first, HV, HV, HV, delay, current, HV, HV, HV, delay forever with the cap pulsing circuit.

              But, this would mean that the NE-2 discharge circuits that are in the FEG book do not work the same way (unless 100V is considered HV). They will not allow "currentless" HV pulses through. Once the voltage in the cap is discharged, the SCR will shut off, so there are no HV pulses. All that charging is just 'normal' current charging from the cap (again, unless the radiant energy in the cap is different than ' normal' energy). Perhaps on NE-2 discharge circuits, you should run the output of the cap through a coil to generate the HV spike, followed by current from the cap. I have done this on water and you do get more and finer bubbles with cap -> coil -> water rather than just cap -> water.

              It is all very interesting.

                I would tend to agree, however, when looking at what happens with the old vacumm tubes in amplifiers and in some of the medical equipment, there are other spikes that are generated. In looking at the Dr. Rife medical equipment, harmonics are generated when pulsing a vacuum tube. If this is the case, then hitting a battery may also cause these harmonics which may just happen to coincide with charging frequencies and we may hit a resonance that causes the battery to charge faster than normal.

                That is why we need to know what harmonics are being generated and you can't see that with a scope. We would need a spectrum analyzer for that.

                Just my two cents for what it is worth.

                • At last... Good charging!

                  I load tested the results from my solid state, after 24 hour the test are very positive, much better than before!

                    I guess I'm a little stupid here, as I do not understand the chart. Are you saying that the battery is 7 different cells at 1.0 aHrs, so that is a 7 aHr battery in this configuration. You are showing 17.xx aHrs usage, did I understand this correctly?

                    Please confirm....did you charge with or without a core?

                      One thing this program does is allow you to combine charts of different runs together. But the strange thing it does is it totals all of the amp hours together when you combine charts. ( so the amp hours on the right is not accurate )

                      You have to look at the bottom of the chart to see the amount of amp hours each run went. The number of cells is not accurate either as the program is not very friendly about entering cell data. Also, I have a VERY hard time figuring out how many cells with a sealed battery.

                      That being said, I have tested the voltages and amps drawn with my multimeter and it matches what is charted.

                      • solid state with 555 timer

                        Hi to all

                        I would like to upgrade my solid state with a 555 timer ic, can anyone render some help regarding this?

                        I do not know how to set the timing for the cap to discharge, will this help me to do that?

                          I learned how to do it by watching videos on Youtube. Look up 555 timer there then build a simple circuit. After that I did a google for other 555 timer circuits.

                          If you get the FEG book from bedini it has a circuit in there with the 555 timer as well as the patent. The 555 timer chip can be varied to fire with changing the resistance to it.

                          • i have a question

                            hi.
                            first post here. i have built the SS charger, the one on page 46 of the FEG book i bought, to spec. works nice. now i want to upgrade the device by adding more pickup coils. i am attempting to have one 6 filar coil. 1 trigger, 1 power, and 4 pickup coils. i am not sure, but i'm making the circuit so each p/u coil has its own FWBR, 3.3 uF cap, transistor, scr and h11d1. i am attempting to make the branching occur between the 555 and h11d1. that is, one 555 branching to 4 h11d1's. before i fire it up, one thing i'm not sure of is, do i need a separate 330 ohm resistor for each connection between pin 1 of the 555 to each of the 4 h11d1's, or can i drive all 4 h11d1's from one 330 ohm resistor? i'm planning on running this with a primary of 24 v. TIA for any help.

                            pat.

                            • HV 1.5kv or more

                              Hi i am looking to create a hv back emf pulse to put across a particially evacuated spark gap. Similar to crooke. We will be putting tesla primary in the tube as well to collect the juice.
                              If i recall correctly grey used around 1.5 to 2kv and i would like to use the same. Can anyone please tell me if it is possible to produce that sought of voltage of the back end of a ssg coil and how. If not would appreciate any ideas on other methods
                              Cheers

                              • Flyback from a 12v source normally peaks around 180-200v (there are exceptions) but it can be stepped up. You could pulse the primary of a 1:10 ratio tranformer (by that I mean the secondary has 10 time the number of turns of the primary) and collect the flyback from the secondary coil. this should be able to generate kilovolt spikes.
