Bedini Solid State Oscillators

[blackchisel97]

I remember

Hi Tyson, Thanks for the update. I'm running test on 12V 20Ah bike battery. She was sitting @ 12.30, right now has 12.98. Oscillator frequency 190Hz. Cap dumping @ 14.15V. Still wondering about frequency/cap dump. I was thinking about trying this on the wheel with strong N poles. I have a rotor with 16 poles from other setup I'm missing all the action The only thing moving in my bedroom is pendulum, which I found very relaxing and inspiring.

It seems 555 is the most prefered version for anyone . A couple of days ago my 555 die. For temporal charger I made a mechanical version. Since it is too loud I made another 555 again.

The new one use diode to reverse the charging. It work, but the power using only one transistor is much less than when using two. New circuit with two transistor made the one wire neon lighted up twice as bright. But since one transistor allow me to charge 3V nicad load directly with new circuit, I use only one. Besides, less power made the circuit very quiet now, the transformer sing rather loud using two transistor previously.

New circuit performance: charging 2300mAh NiMh from 1.23V to 1.35V in 10 minutes. This is my fastest record.

I think I will try to charge 12V 7Ah too.

Direct charging made the battery really heated up. The reason I use radiant charger is the cool charging, if charging at 10 minutes heat the battery up then I prefer 30 minutes. Little longer but never heat up. I remove the diode and use two transistor configuration again. Now charging the battery in series with hho cells again.

New circuit only has 200mA output but the transistor and 555 stay cool now.

Previous circuit charge 12V 7Ah BB SLA from 12.24V to 12.6V in 15 minutes. Since the one transistor version heat the battery significantly, I think it would has similar effect like high capacity capacitor placed in parallel with battery, which reduce battery capacity.

Hi folks, I decided to go with Bedinis solid state circuit since the JouleThief circuit was overheating my transistor. It works well and the heat is about the same, maybe a little bit more than the 555 timer setup is. Though I had to use a 56K resistor where the 18K resistor is in his circuit between collector and base to lower input current. Reason I wanted a self oscillator was because I'm using a 13.8V power supply and was also using a 12v SLA to power the 555 timer which I didn't want to have to recharge. Thanks J. Bedini.
peace love light

Battery report

Hi All,

I did around 5-6 charge / discharge cycle on the 12 volts 35 Ah lead acid battery using Bedini FEG book circuit and later Jetijs circuit. During the charging time I have observed lot of cold boiling and the white color deposit on the battery electrode top surface is slowly dimmed.

During charging the battery voltage slowly rise to 14.15 volts. When the battery is removed from the charger then the voltage at the terminal is 13.36 volts. On keeping the battery for around 24 hours the voltage dropped to 12.25 volts.

On various charging cycle the voltage is going up but there was no improvement in the gravity of the battery.

I had taken this battery to one battery shop for load test. He has loaded the battery from his equipment [dont know the specification but it is a standard equipment used by them]. During the load test the battery voltage dropped to 7.8 volts and the load tester has shown battery as BAD CONDITION.

I dont know why the gravity of the battery is not getting increased.....

Chemicals

Hi All,

Subsequent to the battery testing, I was thinking that we should add some additive into the battery by which we can soften the layer of sulphate for easy removal using our chargers.

I did some search on internet and found that some of the companies are already using such chemicals. Just google Battery service international, they have chemical named PowerPlus. They claim that they can revive the battery within 20-24 hours using chemical and their charger.

Is any body know any chemical which can be added to battery for soften the layer of sulphate.....

Hi Praveen.

I have heard of a few tricks. IMO they improve but may seriously shorten battery life. Some batteries will revive after few cycles, some will need over 20 - even with commercial Bedini charger and a few will not revive. Have a look at the video link which I posted not long ago. John talks and shows changes within battery plates, crystals forming and removing sulfate layer. Your battery is undergoing some positive changes, which you can observe. Try run more cycles; charge - rest- C20 discharge. I'm testing 5 LAB's, rotating them. I'm at 4 cycle . Long process. Make sure your battery has enough electrolyte and add distilled water if necessary. In some cases (if battery is worth the hassle) old electrolyte can be flushed and battery filled with a new one. You can make your own. Battery tester comes handy. You can get one on eBay for $60 but even $7 density meter will give some idea about changes.

During the load test the battery voltage dropped to 7.8 volts and the load tester has shown battery as BAD CONDITION.

I think that means the battery have more capacitive value. Try without capacitor and use something that has more resistance in series with the battery to change the voltage vs current ratio in the load.

Is any body know any chemical which can be added to battery for soften the layer of sulphate.....

Try distilled water. Or try to convert it to alkaline by using alum like show in Bedini video, or use distilled water & NaOH (KOH if the battery plastic case is clear transparent).

Praveen it takes a few cycles my friend.

[pvar06]

Hi Ash,

So far I have completed 6 cycles. The battery condition is improving on each cycle but still it is not in the condition for regular use.

If we need to have 10-12 cycles to revive one battery then I dont think this is a commercial viable project. This is good for people like us, who hooked on to some thing and do research and the open source. But this is certainly not going to change anything.

Any ways I am keeping my fingres cross and just running the charging and discharging cycle on my test battery.

Hi Praveen,

I can adjust output current between 0.10 - 0.15A depending on battery. 555 oscillator runs @ 180Hz. I'll do some more tests today. I need another coffe


Vtech

Hi Vtech,

Thanks for the inputs.

In earlier post you have mentioned that you can get up to 0.95 Amps at output. But in the last post you have mentioned that 0.15 Amps.

What is the input / output voltage and current for your system.....

Also when you tuned the system for higher input current then what is the effect of the same on the output voltage and current [please check this as per your convenience].............

output current

Hi Praveen,

If I ever said 0.95A I must have coffee deficiency or forgot one zero The highest output I could get was 0.225A but not tuned! When tuned, output varies depending on battery between 0.09 - 0.148A. Right now I have large 1000CCA LAB connected and current is 0.099A (99mA). IMO, IN / OUT current ratio is not important. What's important:
* frequency of oscillating part (coil)
* Cap discharge voltage and dump frequency/timing - which means:frequency of 555 oscillator duty cycle
* matching inductance of battery and circuit (coil)
What we want is to charge the cap with right kind of spikes and certain amount, than we want to sharply discharge this cap into battery. As I mentioned before, small caps charge and discharge quickly but we may get pure potential without any current. (capacitor will charge 10 -30V above the battery). I did notice voltage rising fast on the battery but she was down within day or so. Pushing too much current will not do any better. battery needs just a bit to move heavy ions. They have much higher inertia and when they start to move, they will still move even when power is disconnected. This can be observed as battery gaining voltage (charging itself) after being disconnected. I would compare this to the bell, which needs to be hit with proper amount and frequency to resonate. Hammer we use is output current. I see this as a dangling monk on the end of a rope; he needs to pull in the right moment to get even huge bell swinging. It can be deafening experience
What is the input / output voltage and current for your system..... With current battery IN 0.320A OUT 0.099. Capacitor discharging 0.9V above the battery. This is self adjusting; battery voltage is rising so is capacitor and ratio stays about the same.
Also when you tuned the system for higher input current then what is the effect of the same on the output voltage and current [please check this as per your convenience].............
I could get higher IN/OUT but circuit was not tuned and waveform wasn't correct.
If we need to have 10-12 cycles to revive one battery then I dont think this is a commercial viable project. This is good for people like us, who hooked on to some thing and do research and the open source. But this is certainly not going to change anything.
IMO it will, for every person who will be able to make such circuit for himself or for the nice neighbor. Non rechargeable/rechargeable batteries are a huge industry with couple billion dollars profit annually. Imagine for yourself, that you don't have to buy anymore AA,AAA, C,D, etc.
-That you can keep your car battery for longer than normal.
-That you don't have to buy a new battery pack for your power drill or a new drill (because battery pack costs almost as much as new drill with battery included.
-That you can buy small 12W solar panel, keep your circuit running for free and have a couple batteries topped in case of power shortage. Couple golf cart or any true deep cycle batteries will keep your fridge/freezer with food and few lights running, instead of flashlights, candles and throwing thawed food to the garbage. There is plenty batteries discarded by people, which you can get for cheep if not free. I use to live in a rural area and remember power shortage due to the ice storm. Some people didn't have power for 2 weeks. Just imagine comfort of having lights, hot coffee and food not getting spoiled. At that time I had a wood stove with water jacket and cooking surface but this may not be an option when one lives in the city, and has to move to the shelter. I would even consider investing in Surette batteries (Google them) There is a factory not far from where I live. They would provide good amount of power when charged with John Bedini technology combined with solar power. I believe there are other options not explored by me yet I apologize for a long post but I believe this has a potential for every person. BTW, we all have friends. Show the what can be done. This is far more interesting than any TV show

Computer PSU transistor better than 3055

I try using a transistor salvaged from computer power supply today (KSC5027). It mentioned to have 300uS fall time but I already see huge difference of my oscillator output. The reading in the DMM is flickering 364V and out of range. I think MOSFET would improve the output even more. The circuit output current is still 200mA, same as 3055 one.

[blackchisel97]

transistor

Hi sucahyo, 3055 is a technology which I widely used in my high school time experiments - 70'. There are many bipolar transistors today which will perform better. As I said before, I have tried different ones with various results. We need a perfect switch and a fast one too. I have a few hybrids, having combined best characteristics of bipolar and MOS technology, which I would love to try it. In this particular circuit I don't see great advantage of MOSFET over SCR but I believe they would be beneficial in others. Of course, I may be wrong
