Maaf masih pemula, saya coba pahami JT itu pakai trafo tegangan kalau stingo pakai trafo arus (current transformer).. Benar apa salah mr. sucahyo ?? joule thief butuh trafo dengan dua kumparan (dua duanya primer), sementara stingo bisa pakai trafo satu kumparan atau lebih.

Hi Sucahyo,
My stingo built is still running well with the TIP41/42 chips. I noticed that I have 4 chips on the same aluminium heatsink with no mica - I have not had any problems!
I want to bigger version for faster charging big batteries - what is the highest powered transistors you know of that will oscillate in this way. For example is there any reason that a MJ15015 (NPN) and MJ15016 (PNP) cannot be used?
Thank you, Mark

Thank you, Mark Nice . no mica = no insulation between the metal behind the transistor with the aluminum heatsink? I had tried some 16 Amp transistor and they can not withstand it. It seems the maximum current the transistor can withstand is 2Amp at 12V input. I even tried the one recommended by Bedini (MJL21193 / 94) and it still dies. I also tried 2SC2922. They are not better than TIP3055. So unfortunately, we can only use multiple stingo if we want to increase the power. I have tried combined 3 stingo. To increase efficiency, I would try stingo driven by stingo like I mention before.

I don't remember you talking about driving a stingo from a stingo. Do you simply take the positive output and use it as input for a separate stingo circuit, including the HV spikes?

Do you simply take the positive output and use it as input for a separate stingo circuit, including the HV spikes? Strange that it work fine. The goal is to drive the transistor with the spike. The forward spike will turn on the transistor. The reverse spike in theory should speed up the transistor turn off.

Razor Nicd batteries life test. 10/12 hours of charge with its charger, 30/34 days life 2 Hours with stingo 14 days life 4 hours and 30 minutes with stingo 30 days life I set the transformer of 1 amp on 7 v during the first test and on v 9,45 during the second test. The transistor stay cool at those tensions and when I charge the lead acid at 12 V with the 2 amp transformer, the transistor hits a top temperature of about 45 °C. I should try a more powerfull stingo. with this one I just need more time to charge a battery but is efficent. May be it's possible a shorter charging time isn't it ?

Thanks for sharing. Yes, it seems your stingo power still can be improved. Transistor stay cool show that stingo still do not run at full power. I think your power supply power output is too low for the stingo need. Try to find a stronger power supply. You can use computer power supply too. Short the black and green wire of ATX power supply to turn it on. Use yellow and black for 12V. See how much difference the stingo run using the transformer vs using the 12V battery. They should be the same, otherwise the one lower is the one that is not capable of supplying enough current. If they are the same, then try to reduce the winding in your coil to half the original.

Some days ago I found that a 12 V 1,3 amp lead acid battery was dead, I measured 5 V. I tried a charge. Now the battery is at 12,23 volts, I charged it yesterday up to about V 13,6.
I built a bifilar pancake coil I connected to stingo but I burned two resistors, have to find the proper connection.

Most the battery I tried to recover had corroded electrode inside so it can not recover. Good luck.

As usual I'm charging the NiCd batteries of the razor for many month I could last it for 30 days. As you suggested I changed the transformer and used an ATX, I couldn't see any current changing on the ammeters one input the other output, but the batteries last 37 days quite a lot more than ever. Last year I connected Stingo to a solar pannel but I burned a couple of resistors. I'd like to try the solar pannel power 58 Watts, the ATX is 300 Watts, more powerfull but stingo charged safely, is it necessary to set a regulator ? the ATX has a controlled current and tension, a solar pannel don't. Do you think should be necessary a tension regulator like the one can be installed on cars, from 6 to 24 V input, 12 v output ?
I made many small coils and put in a glass jar and covered with oil, I put it in the same place where I had the cemenite before. I want to see the effects. Did you try materials other than cement ?

Sorry for the late reply. Thanks for sharing. It is interesting that you can not see the difference of current between transformer and ATX. But the difference may show that the ATX allow more maximum current. Which resistor that you burn? I don't think regulator is neccesary but since the output voltage of solar panel vary a lot, if we set it at maximum power during cloudy day then stingo can overheat during clear day. I have yet find the methode to automatically limit stingo's input when the voltage increase. Using regulator is a bad method because it may reduce stingo efficiency a lot. You can try IC solution like LM 7812 to regulate voltage but I never try. You should use water instead of oil because the insulation have the same property of oil. The layer in theory supposed to be copper insulated by oil or PVC, surrounding hexagon crystal. The cement or water replace the crystal. You can also try ammonium alum solution. If we flood the coils with ammonium alum, and then let the solution dry, crystal may show up. You can try other self made crystal. We need to find the one that produce hexagon crystal. Attachments:

Maybe the meters available cannot measure all kind of energy we have around or produced by such electronic devices, anyway if the batteries will last more than before using ATX that mean, a more powerful source push more energy in a battery. I’m afraid I don’t remember which resistor I burned, but I want to try solar panel + stingo so I’ll tell you what will be, I thought I burned a transistor surprisingly I found resistor, one or two I think. I tried with this mono stingo splitting water ( tap water ) + some salts in it, but more test has to be done. When I connected the panel to stingo, current and tension could vary a lot and burned resistor. I installed in my pc on the mother board a very small atx dc/dc ( fanless ) 125 w, with a wide input ( 6-24 v ) is 95 % efficient at 50 % of work I save 30 % energy compared to the standard atx, It has been working good for almost 4 years. Probably a diy regulator can work as well, need thinking about it.
I though about water but copper oxidation isolate spirals, my experience is based on oscillating circuit studies, but cemenite is new to me, so I think testing it is the best way. I put first the small glass jar near the petrol pipe than I put some more spirals in it and put the jar under the pipe, but the engine I don’t know how to say, it was like braked, since many years I’ve been testing with magnets so I can feel the motor variations, one day I felt the engine running rough. Once at home I checked the engine, I lost the cemenite. So cemenite need spirals in a material that structure itself in an hexagonal shape for a proper work, doesn.t it ? I’ll try some salts.
Thank you.

Thank you. yes, we should not only rely on normal meters. We observe the real effect too. For solar application please measure how much current goes to stingo. Maybe you can use a simple relay in series with resistor so when the voltage goes beyond certain number, the relay will turn on and disconnect stingo. Yes, stingo can be use for water splitting. It seems to be efficient too. Use only single diode for the output. The one that ruin the battery is the one that split water better. But do not use salt. Salt is NaCl. If you use it, the you end up with NaOH and Cl2. Cl2 is Chlorine, a toxic gas, nerve gas. So it is better to just use NaOH or KOH. If you use PVC container, use NaOH. If you use Acrylic container, use KOH (I hope I am not wrong with this). But actually you do not need salt or other catalyst because stingo can automatically adjust its voltage. I usually experiment without catalyst. It is interesting that you can make your own ATX. How do you know it is better that off the shelf ATX? Yes, cemenite need spiral in it. The spiral need to cover the whole cemenite otherwise the cemenite will polarize and loose its effect. You can make it work again if you shave off the part that do not contain spiral. Cemenite work better for a vehicle with lean fuel mixture. So, check your car fuel mixture. If it is rich, then adding cemenite will make the engine felt heavy. You must find the correct cemenite size. If you felt the engine become heavy, saw / split the cemenite in half (better if it is still in tubular shape) and try again. Do not put cemenite too close to the engine or radiator pipe. I think the engine block need the opposite of cemenite energy. Remove the magnet or ferrite if you use any. They interfere cemenite effect.
