mantap mas...mas mau minta sarannya sekalian, hehe 1. Stingo lebih cocok untuk ngecas Nicad atau NIMH? 2. apakah bisa stingo dgn input 3V max 10 A dr power supply PC, ngecas 36V 10A Nicad / Nimh Battery pack? 3. Kalo baca catatan mas d forum, untuk indikasi full nya NIMH atau nicad adalah 1,45V per cell y? Tks mas..

Sudah saya coba dan lebih cepat dari charger komersial. 2. Bila pakai power supply PC mending pakai 12V sekalian. Bisa dipakai ngecharge 36V juga, namun perlu dilihat kapan charging harus dihentikan. 3. Tergantung kekuatan charging. Biasanya pakai ukuran setelah dilepas dari charger punya nilai 1.35V. Saat charging voltase bisa sangat tinggi atau cuma lebih sedikit tergantung pakai kekuatan charging berapa.

mas sucahyo klo bikin coil toroidnya pakai apa pa? (nyari besi donat nya dmn? Trus itu lilitanya pakai kawat apa ya? jika pakai kawat enamel gimana? trims ferit donat memang langka. kalau nggak ada nggak wajib kok. Pakai adapator 500mA juga bisa. Hambatan dari coilnya yang penting. Usahakan diantara 0.5 sampai 2 ohm.

Pakai charger hp lama karena stingo butuh suplai arus instan yang besar. Mungkin bisa lebih bertenaga kalau dibantu kapasitor besar.

Sepertinya memungkinkan kalau sumber daya untuk rangkaian tersebut pakai yang lain. Tapi susah juga karena stingo bisa menghasilkan charging voltage lebih dari imit normalnya 14.5V.

Hello , I came across the stingo circuit the one with a 6 amp diodes bridge , I used the transistors bd241c and bd242 c. I charged a 12 V 1,3 ah its tension was 9,20 V ( it was charged with a bedini ssg I built 2 years ago ) in 6 hours I reached 13,75 V and then I stopped it After 2 weeks the battery is still charged, not fully charged 12,35 V, but much better than before !! I used an ignition coil ( 1,1 ohm ) I got for free, it is noisy and the electromagnetic field is strong ( can feel it ), the transistor bd 241c has a heat sink, it gets hot. I tried a flyback transformer from a TV less noise and electromagnetic field. ( 0,5 ohm ) I feed the circuit with a 12 v 2 Amp transformer.
Than I tried a toroid, external diam. mm.45 wire mm1.5 ohm 0,3 I should try a toroid with higher resistence, I don’t hear any noise, the bd241c I charged 4 AA NIMH in 8 minutes up to 1,402 V Khz 12 input 350 ma output 290 ma This fast charging performance don’t give me other informations, the batteries tension slow down because they are old.
Charging the 12 V 1,3 ah Input 400 ma output 100 ma. As you can see performance change.
It seems that the coil construction and the type of battery affect the charging performance. My compliment Suchayo.

My compliment Suchayo. That is great result . thanks for sharing. Yes, transistor get hot easier. You may need to use fan too. It is interesting that the noise is unrelated to the coil resistance. Stingo demand a lot of sudden current, using 2A transformer may not be adequate. I once did an experiment, stingo that use 2Amp current actually make computer power supply hissing and auto shutdown even when it supposed to be able to supply 20A. Charging 4 NiMh in 8 minutes is a really great result if you use that adaptor. Yes, stingo produce more amp with lower resistance load. So charging can be faster if we charge the battery in parallel.

Toroid R 0,3 ohm Khz 30,4 Input 370ma Output 50ma No hiss -------------------- Transformer crt tv Circuit A R 0,6 Khz 10 Input 570 ma after 2/3 seconds down to 405 ma Output 100 ma after 2/3 seconds down to about 75 ma Very low hiss -- Circuit B R 0,60 Khz 1,3 Input 370 ma Output 50ma Hissing
Did you try other coils just to check power consumption ? With the coils I tried I measure between 300 and 400 ma from transformer to circuit. I tried with a 12 v 3w lamp + a motor taken from a hard disk and charging a battery 12 v 1,3 ah at the same time, tuning the 500 k pot at the maximum resistance, the motor run, the lump lit and the battery is charging slowly but is charging. How powerfull a stingo can be built ? I tried to charge 4 LR44 button cells batteries, the first measure of the 4 cells was only 250 ma, totally dead. I charged with less power as possible for 1 minute alltogether tension during charging went up to 12 V so I stopped, tension slowed down after some time to 3,6 V. than I charged again for 1 minute, tension after some time went down to 5,3 V a bit better. I lit a small torch, in few seconds led were fading, I charged again 1 minute and I saw that cell buttons were a bit more powerfull. Being carefull it is possible to give some more life to dead no rechargable batteries, just a quick touch of energy every time. In case of emergency or getting some light for free.

Thanks for sharing. It is interesting that tv coil consumption reduced after 2/3 second. IIRC tv coil have internal diode . Yes, I did try other coil. yes the power consumption change. I found that different coil need different resistor value if I want to get the most efficient output. It is better if we replace all resistor with variable resistor. It is nice that you can charge and run motor at the same time. Stingo power limit depend on the transistor. But even with 25amp transistor, the maximum input current is about 2 Amp before the stingo die. I usually limit stingo input to 1 Amp. Stingo with low input current is more efficient so it is better to combine many low power stingo instead of creating one stingo with big power. Stingo combination is more efficient too than single stingo. Nice result with button cell battery. Yes, it is possible to charge alkaline or zinc carbon battery. Unfortunately we can not fully charge it. It is suitable for low power application, for example digital or analog clock.

Yes just half charge and be carefull not to exceed charge, leakage it's possible, but with stingo seems to be much better. I 'd like to charge an electric razor, but I should take the risk, because batteries inside are metal labelled, welded on the electronic board. Could pulsed high frequency power from stingo damage the board. ? did you experienced such charging or any other directly into electronic stuffs ?

I think it would be fine as long as you connect the load when the stingo is off. And make sure that the connection is secure. Because if the connection is intermittent, then the stingo would have the chance to reach very high voltage that can damage the other component. I don't think the high frequency can become a problem. You only have to watch the voltage. Electric razor also have durable component. But there is a risk of destroying the electronic if the battery is bad. The voltage can go very high. To be safe, start with low power first, see the change of battery voltage. When you notice the voltage is still at normal range, continue.

I modified the razor board, I welded 4 copper slots made of wire of 1 mm bent 360° the metal labels of batteries can be put in and out easily. I charged for the first time with stingo the 2 batteries that are NICD and not NIMH, I used ignition coil 1 khz and lowest position of the pot 500 K for 75 % of the charging time, then I gave more power I thought to go safer and slowly in charging. Do batteries get chemically stressed if charged fast or too fast ? I don't know, this is a pulsed charging, the batteries were cold during charging time , 85 minutes, from 1,206 V up to 1.390 V ( charging time with its charger 8 hours ) I measured the temperature of the aluminium fan of the BD241C 60 °c at the end. I'll see how long the charge will last. I had just a try with a solar panel some days ago it is a 49 W just letting the sun rays hitting a 20 % of its surface and I could see the amperometer jumping up to 1Amp ( the amperometer limit is 1 amp ) I'm thinking to built a double stingo as per your scheme and see, may be would be necessary to limit the current, because the board stopped with such current from the solar panel. I connected to the transformer and started again. Toroids must have same resistance and construction ? or can be used different one in a multiple stingo ? In case I can try, but I see in your circuit 2 car coil combiner that there is no advise of diodes type, 1N5408 are to be used ? there are 2 input batteries, can be used a single input battery, solar panel or transformer ?

Even if the battery stay cold, radiant charger produce more gassing effect. So it is best not to avoid overcharging especially on such battery. It is best to charge only 80 capacity to make the battery stay long. But from my experience, I only destroy NiMh or NiCd when I forgot to turn the charger off and cook the battery. And charging to 100% full only make the battery as warm as our body. Yes, stingo should run on low voltage output only, so we make stingo produce max power at low input and turning off to prevent stingo from overburn. I dream to design stingo that produce constant output no matter what the input voltage is. It is better to add big capacitor (around 10000uF) in parallel to the input. It is not neccesary to use the same coil for stingo combiner, but it may cause uneven output, or difficult to set similar maximum durable output because one will heat up faster than the other. The diagram in the first page use 1 input battery. You can use the same input battery even if you combine 10 stingo. The suggested diode is mentioned in the diagram in the first page. the important thing is the diode that is used to direct charging current must have enough current rating depend on the current flow. For example, voltage 12V, coil 1ohm, allow 1amp current. When the input is off, if we assume the coil have 12V voltage, coil 1 ohm and battery internal resistance 1 ohm, then the the current flow to charged battery is 6 amp. So we need 6 amp diode. If we assume the coil have 12 watt, then the current would be under 3 amp. But there is only one diode that direct current flow from charged battery negative to input positive. So if we combine two stingo, we may need 12 Amp diode. This is only estimation, we may not need such high amper. We can check it by measuring that diode temperature. I start to use 6 amp diode after IN4007 melt down the soldering after running the stingo for few hours.

Charging NiCd of razor: it stay cold up to 1.39 V, I first used a 12 v battery as input power, the coil has a Fe Si cold rolled multilayer sheet as core, (transformer from an old B/W tv ) frequency 1 Khz. 85 minutes of charging I used the razor 7 times down to 1,206 V During the second charge I used a toroid, frequency Khz 5.91 up to 1,39 V , charging time 17 minutes I used the razor 3 times down to 1,176 V.
The stingo I connected to solar panell without condenser works, the Bedini wheel on the contrary need condensers.
Thank you Suchayo
