I am very , very interested in your circuit , would be perfect for a coilgun ! is that a 330v/500uf capacitor ? can you reupload the circuit schematic.Damn in Romania you can't find disposable cameras so i would have to build the circuit from scratch
it is impossible to get one of these cards, the ones on the model thats in the stores now are slightly different. and they are red not green? does anybody know the to find the schematics for the red ones? or a video tutorial like this? if you don't mind making another video?
@Halo2maniaccc i have a 4 pin transformer and i wraped a new coil around the coil 3-4 turns the capacitor charges but too slowly (approximately 3-4minutes)should i use another resistor>? or make less or more turns on the coil?
The five pin transformers have two coils but one of the coils has 3 pins. The middle pin is a center tap that is part of the circuit that switches the transistor on/off. I haven't really looked into it but without the center tap you need to create a circuit to oscillate the transistor. Using a 555 timer to switch the transistor at about 30khz should do the trick.
I don't have any schematics or what not. If a 555 circuit is too complex then go look for more cameras with 5 pin transformers.
@Halo2maniaccc yes you need a new circuit but what if you add the last coil that one which apears to be the smallest and is connected with the primary (through a 220ohm resistor)and with the secondary what i'm realy asking what is the ratio of the 3 coils on the transformer
I went to walmart and asked for some old cameras, the woman told me that she wouldn't give them to me, because, and I quote "they have batterys in them, you shouldn't play with batterys, you could die!"
the shear stupidity of this woman shocked me, untill I realized she was about 40, and working at walmart, then it made sence
Just completed and tested, why waste time charging caps, used it to light a 15W fluorescent tube with a 1.25v NiMH. Not as bright as it could be, but would probably do quite well lighting an 8W fluorescent or CFL.
This could be a Super Joule Thief.
Tested output at 306 v at 7.8 mA.
One point though, the output polarity is backward, wires should be switched to reflect the red/positive, black/negative polarity.
It had been a long time since I wished a detailed explanation of the shematic of the mini transformateur. Thank you! And very well explained video ! ;)
The detailed schematic got removed from the image website I will see if I can find it and reupload it. The two other links in the video description are more than adequate to understand the circuit in detail. Check them out !
your first link is broken and for anyone interested in downloading the diagram rightclick the white space outside the image---> view page info---> media---> save as: the process may be different if you're not using firefox.
OR you can just open it up cut the wires from the flash and just extend them. use the existing batery and button and everything and voala same results. only thing i can sugest is not to try to shred the wires on a 500V capacitor with your teeth.....it REALLY REALLY HURTS!!!!!!
I am not sure usually they don't have labels or they are very small and hard to read. It would be a low voltage fairly low current npn transistor though. Look around online and I am sure you could find one that would work.
the last thing... in the other image, the one of the circuit with 2 diodes there are: 1 transformator, 1 transistor, 2 diodes and the other thing seems a resistor but I can't see it clearly, could you tell me what is it?
This circuit has 2 diodes, a transformer, a transistor, a surface mount resistor under the circuit (or two I don't remember) they look like little black squares on the circuit. The schematic linked in the video description shows the entire circuit schematic so you could check that out.
I don't understand what your asking? The original board has many small components but many of those are part of the 2nd stage which makes the flash. The first stage charges the capacitor and that is what I hacked in the video to make it smaller. Anything not in the video is not necessary to make it work. Finally the big capacitor that was originally on the board is reused, watch the end of the video when I test it.
sorry to post again, im worried about my capacitors seeing as i have a very limited supply (only 50 x 330-400v 80uf) and ill probably not get any more for a long time as i stole them from a camera shop, is there a way to regulate voltage from the circuits cos im getting 500 volts from the two in parallel or is there a simple indicator circuit i can make to warn me that im overcharging my caps?. My electronics knowledge is pants. thanks
You cannot really regulate the voltage but you could turn it off. Use a voltage divider to drop the 500v bank to a lower voltage (1.5v). Then use that low voltage to turn on a transistor amplification circuit which would control a normally closed relay that sits between the battery and charger. When the bank gets to 500v the circuit would turn on and power the relay breaking/opening it causing the power to get cut thus stopping charging.
will it decrease charging time if i simply wire two of these circuits in parallel? that being said will i need more batteries (+1 battery per circuit) or will it just need one?
This is something many people have asked about and honestly you just have to experiment to find out what works. Get 2 circuits and try them in parallel, try them with 1 battery....2 batteries ect... Time the charging time and then compare it. When I tried to do parallel circuits I couldn't get them to run only one would turn on but others have gotten them to work. If both circuits work then yes charge time should go down because of an increased charge current.
@Halo2maniaccc yeah thanks, damn it i destroyed one of my circuits, i had 4 funsavers, one of them is the wrong type of circuit layout and one of them i have destroyed the transistor.
@Halo2maniaccc yeah thanks, damn it i destroyed one of my circuits, i had 4 funsavers, one of them is the wrong type of circuit layout and one of them i have destroyed the transistor.
@Halo2maniaccc i've finished my circuits now and i just need 1 battery, i guess it just drains the battery faster (resistance is halved current drain is double)
how much input voltage can this lil board take b4 ir burns out? i applied a 9v to a camera board once and it fired in a sec. the max V i apply to my input on my mini coil gun is 4.5 (3x 1.5vAA) because i am afraid to burn it out.
The board should be run at 3v to stay safe 4.5v doesn't give you all that much more. Anything more and the board will fry do to way too much power going through the transistor on the board. Keep it at its current voltage if it works and don't change it. If your in need of a higher power charging circuit you will have to build it I have several links and designs varying in difficulty and power I could send you just message if you want them.
@Halo2maniaccc 1 1.5v AA battery did not charge quickly. my bank is 3 in series 5 sets in parallel (15 caps total) voltage total of 990v. i doubled the batteries going into this board and it shot up to the range of 600V. i decided to double that with 6V in thats when it all went wrong. its there a way to make a decent portable DC cap-bank charger?? i was all over the ACG site with no luck. i cant make the boost converter and not all boards i have seem to have limiting resistors to remove.
Google ZVS flyback driver and on google images to get the schematic. There are also youtube videos of it so look at those as well. If that design is too hard google single transistor flyback driver. The flyback can be taken from a crt monitor or projection tv and ALL off the components (two resistors and a big transistor) can be obtained from radioshack. That was the first driver I built and it charged MUCH faster than a camera circuit.
I do not really know, I have never come across a 7 pin transformer in these cameras. You best bet would be to go to Walmart or a local photo store and ask for their used cameras (they should just give them no charge). Go to many places and do that, and soon you should have hundreds of disposable flash cameras. One of those many is bound to be the right transformer! So my advice just keep looking for a 5 pin transformer.
Next time use a very fine tooth hack saw or a dremel with an abrasive cutting disc on low to medium speed. It may take some time but its better than going at it with pliers!
I can't say that I haven't tried doing this before.................
The transistor is the small black component on the circuit board with 3 legs, I am unsure as to what model number the transistor is as its really tiny.
This circuit is essentially a voltage booster, 1.5v to 330v. Its nothing super special and its purpose is to charge a capacitor. So yes you can use this circuit to charge your big capacitor but it will only charge to 330v (if your cap is 330v+ it simply won't charge it all the way) it will also take longer to charge depending on just how large your capacitor is.
Oh ok.. The cap is thicker than my thumb! I fell of my chair when I got shock by it at full power! The only way to charge it is by using the original driver that came with it, but is to large to fit anywhere..
Yea you should watch out, capacitors that big can deliver enough of a jolt to cause irregular heart beats and eventually a heart attack.
You should be able to charge it from this charger, if its a basic capacitor then it shouldn't have a problem.
And if you think thicker than your thumb is big you should see some of the capacitors that I have. They are thicker then my forearm (3in diameter) and are about 12 inches long = to about 200 photo capacitors! This will not shock you it will KILL you.
lool where did you get those? you could build a power station in your room! Think my cap can´t realy hurt me like a police tazer.. by the way, where can i get one?
I got them off ebay, a guy had a used industrial surplus and sold them for next to nothing. Your cap can hurt you, a tazer is different it delivers high voltage low current to disrupt the nervous system and inflict pain. The capacitor delivers high voltage & high current in a massive jolt which can stop a heart. If you don't know what your doing don't play with these capacitors there is no second chance it will KILL you instantly.
When I say that the small capacitor will stop your heart think of it like this. You can throw a small wrench into an engine and stall it but that small wrench can't restart that engine. Your heart is the engine and the wrench is the capacitor.
BTW you have to use SCR's to switch these super big capacitors no switches can be used or they will vaporize the contacts & (possibly explode the switch apart) !
I take no liability if you hurt yourself using the information that I provided!
no no .. I don´t wanna mess with that kind of caps . when i ask you where can I get one, I was talking about the Tazer not the cap.. i´m ok with the size of mine :) ( cap ) xD
But thanks for the advice, I had no idea it could be dangerous..
I really don't know how, if you have some extra electronics knowledge you could use a 555 timer to make the transistor oscillate. I can't really help with the schematic for that, just research it and build it. Go to walmart or any photo store and ask if you could have their used flash cameras. You are bound to find the right circuit. Kodak may have change the type of circuit in the cameras which I will have to check on.
I am aware of this, I never made the video. It turned out to be a bad flyback driver lots of heat with very little power so I abandoned it. Give it some time and I will make a ZVS driver for the flyback but I have to order parts. In the mean time why not google it, the info is out there.
Yes you need the external diode or the board will not function. If you need to get an extra diode you can either carefully (WATCH THE HEAT!) desolder one from another board or get one from Radioshack or preferably an online vendor such as digikey or mouser.
No problem. These are great for coil guns SUPER COMPACT I wish I had created this mod when I first started electronics I remember using full sized jumbo camera circuits lol. This is so small and sleak that you can practically put it in any project enclosure! Be safe capacitors from these cameras are not toys and enough of them can stop a heart so be really careful not to zap yourself with them.
Do what with a flyback? If its charging then yea its possible I know I said that a tutorial was coming but I had stopped work on it due to inefficiency and slow charging. I may start working on a new one however 555 timer driven or a ZVS system however the tutorials will be more complicated but still step by step and the parts will have to be internet bought.
I built this tonite. It is awesome ! I am potting it in jbweld. So I was wondering, what's the best way to switch that 330V? I tried (on the bench) using a household light switch, but the cap kept arcing. SCR maybe? Oh, I wanted to ignite my rocket igniters with it. Thanks for a great vid !
The best way would be an scr but if its just 1 or 2 capacitors a push button switch from a hardware store will suffice. Make sure its in a nice plastic project enclosure, you don't want to touch hv leads! Igniting model rockets with this is the best it provides instantaneous ignition!!! Not the (1-2) second delay AA batteries give!!!
I never used AA batteries, always a 12V. This circuit doesn't work, but I think it's because it discharges so fast, it doesn't have time to melt the wire (igniter wire). I paralleled 3 of these caps, so there's plenty of energy, (E=0.5CV^2), and it drains 2 AAA batteries to almost dead after just 5 shots, so maybe I'll make a coil gun instead, and come up with another scheme for my rockets. Thanks again for a great vid.
You must be using a different type of ignitor with thicker wire, I used estes model rockets, motors, and ignitors. With 4 capacitors it vaporized the thin wire in the tip causing the ignitor to make a large spark and loud pop. But if the wire is to thick then it will not work.
No, because it only outputs 330v. That's not high enough to see any arc. You would have to get a transformer that boosts the voltage way higher like 2kv minimum.
with regards to the circuit, i have a few different types of camera, all containing 5-pin transformers with 3 on one side and 2 on the other. but they all sem to be wired differently. like different things go to different places than yours does. are all of the transformers the same, and can i just wire all of them the same as yours and they will work, or are some transformers differnet and will also need to be connected differently???
If the capacitors are all 330v and the transformers are all 5 pins then they should be no different from the transformer in the video. They are basically 1.5v to 330v center tapped transformers, its nothing super special but if they are the same then my schematic will work assuming you wire everything up the same. Watch the transistor though if it gets to hot when soldering it gets destroyed!!! I did this many times....the frustration it causes lol
Well if it fails while its running you will smell a nasty burning plastic smell and a small amount of smoke will come from the transistor. After the smoke clears there will be physical damage on the transistor usually its split apart down the middle. It can however fail without the above and it just won't work when you give it power. If this happens make sure everything is wired right, like the diodes and capacitor. If it is and it still doesn't work then I would say it is a bad transistor.
Yes, if you don't remove or damage the led during the mod it should light. Mine lights every time at 320 - 330 volts like it should. You can also de-solder the led if the led is burnt out and solder wires on so that you can you an external led in say a project enclosure or box!
With 3v input the output voltage didn't change but I noticed a faster charge time because it drawing more current. If you simply increase the input voltage without changing wires or anything then it will work with the capacitor without problems. If you go to high on the voltage then you will hear a sizzling noise and smoke will come from the transistor!!!
No, it doesn't matter which way a resistor goes. The color bands on larger resistors and markings on smaller resistors are just codes to tell you the resistance of the resistor.
Just make one its really simple. I can show you the schematic. It only require very few parts. One only needs to learn to read schematics, and thats it.
The disposable camera circuit is very basic and universal but each manufacturer has their own little twist on it. Mine has an oscillator in it, without an oscillator the circuit wouldn't work. The transistor is the oscillator in this circuit. It took me forever to understand how these little circuits worked!
Current cannot be induced continously to the secondary winding using DC current. Househould ac current makes it convenient because its already oscillating at 60HZ (60 cylces per second. The camera uses ferrite, or powdered iron making an efficeient transformer with 80% turnover, probably oscillates at 40 to 200KHZ.
Yep that's the best way to sum it up. Except I remember reading that the camera circuit starts at around 40 - 50khz and dip's down progressively as the charge increase to around 15khz because it operates on feedback voltage.
I once made an oscillator to drive a cars ignition coil. They did not last very long. LOL They can't seem to withstand very high frequency current. It was fun tho.
If you used low current transistors that were made for low frequency applications then they won't last long. However if you use high frequency high current transistors it should last for a very long time. It could also depend on circuit design ect... Ignition coils are a lot of fun to play with!!!
I was using an HD video camera but even then the camera can't pick up everything, the bang was much louder and the flash was brighter. It may not have had a full charge as I wasn't measuring it but it was more of a proof that the mod worked than to fully charge the capacitor.
have you measured the output? the camera flash circuit reaches 330v via two coils acting like a tuned oscillator, if you are using only one transformer are the coils configured to reach 330v (or higher?)
The basic transformer is 2 coils of wire wrapped around a ferrite core. The camera transformer has a specific ratio of windings between coil 1 and coil 2 (1.5 to 330). This provides the voltage boost and current decrease. So the transformer is only configured to reach 330v.
I thought in the original camera circuit it was the capacitor that limited the voltage across itself in this case 330v? and since the cct. is an oscillator it would continue to gain voltage so long as it had legs (current) or until it reached the caps nominal voltage rating? that's why people have been using the cct. to charge banks of large capacitors! Try measuring the o/p then you will know turns ratio on the transformer...
I have attempted to charge up 500v capacitors with disposable flash camera circuits and the charging stops at 330v. The transformer is what determines the output voltage its all about that ratio of the windings. Large banks of photo capacitors in parallel just take longer to charge, in series the voltage increases across the capacitors but you don't need a higher charge voltage. Its sort of like battery's, series increases voltage, parallel increases the current.
If I want to charge a few capacitors in sequence, could I do it with these resources? I have about ten of these cameras that I plan to use for a coil gun.
If by sequence you mean charge multiple capacitors in parallel (or series) then yes you can use the camera circuit to charge the capacitors. The more capacitors you add however will increase the time that the circuit takes to charge them. Just google flash camera coilgun, there is a ton of information on it.
Normally the circuit is run at 1.5v but I have successfully run them at 3v, the extra voltage notably decreased the charge time. Don't run it higher than 3v though because the transistor will burn out.
Hi, i was wondering if someone here could help me...
i would like to use a thyristor to discharge a flash capacitor, i just tried it a minute ago, it discharged once, when i pressed the button, but now there is a dead short across the thyristor (i take it thats what the pop was). could someone tell me what i did wrong?.
i put the cap (-) on the cathode along with the (-) from the 12v battery, i put the cap (+) through coil to Anode, and the battery (+) through a 1k resistor, switch, to gate.
It sounds like you may have burnt out your thyristor. I have a huge one rated for 250 amps continuous at 500v (7000 amp peak for 2ms) and I have hooked it up in the exact same manner you did without any problems. The capacitors that I hooked it up to were also 100 times more powerful than a flash capacitor. The thyristor was probably not rated for such a high voltage and current. I could be wrong but this is just the most logical guess that I could come up with.
thanks for the reply, came to that conclusion, when i replaced the thyristor, and added a 330ohm resistor, i repeatedly charged and discharged the cap, until the camera charging circuit stopped working :-( lol.mine was rated at 8amp @ 800v , i suppose i better see how much a descent one will cost :-/. thanks
Hi, me again, been looking everywere for a descent thyristor, how much did yours cost? did it run into £100's?. have you aver had a schock of one of these? it hurts!
Can you connect multiple transformers to increase capacitor charging? like the picture that showed input and ouput wire. Connect another tranformer to input and then connect it to the output. (Put it in series I mean)
I don't think that would work because each circuit would not be synchronized with the others so you would have a really weird output. This can be done with batteries obviously but with using multiple transformers in series it would be really hard to get each one synchronized and pulsing at the same time. With a 555 timer you could do this but the camera circuit is based off feedback so the charging frequency changes based on the charge level, initially its like 40Khz and it ends at like 10Khz.
"Why cant u just hook the cap + battery directly to the amp, and screw the diodes and transistor? Last i thought this was a 1.5 - 320V transformer, and the other parts are just for too much into the transformer...."
ya, youtube does this weird thing when you post a reply to an older comment, it posts your comment after the older comment and at the beginning of the list.
The transformer uses DC current which is steady direct current with no alternating or switching, AC current alternates 60 times per second. The current must alternate on and off into the transformer in order for it to work. The transistor switches the DC current on into the first transformer coil, then it shuts it off which allows the energy in the first coil to move to the second coil where the voltage is increased. the diodes then rectify the output to be 330v DC. PM me if you need more help!
I was in the process of making the flyback tutorial but it was so unreliable and in-efficient with the components from radioshack it took 1 minute to charge a photo capacitor. I have also not been able to find a good transistor for the single transistor driver. I might do a video about the ZVS driver with a parts list, schematic, and tips on building it. This video won't happen for a while though, I don't have a lot of time to make the videos anymore.
why do u add an extra diode ....there already is one on there
and besides that, i think the way ur cutting the board, is cutting off a small capacitor from between the transistor pin3 and battery minus, does that affect performance?
If the extra diode is not added the charger will turn on and the led will shine but it won't charge. I am pretty sure that the extra diode prevents the capacitor charge from flowing back into the transformer which will prevent it from charging. Without the extra diode the circuit will not charge the capacitor. As for the capacitor I thought the performance after I cut it off was better but I can't see a little tiny capacitor really affecting performance that much.
no but really the circuit already has the diode to rectify the current from the transformer and to keep the capacitor from discharging backward...i gues if u tried the set up both with and without the extra diode and it only worked well with the extra diode , then sumthing wierd is going on
Are you talking about bridging the transistor and transformer? They are not connected if you look closely at the pcb the blues lines are the electrical pathways not the dark spots. There is no blue line going from the transistor to the transformer pin so you must solder in a wire as a pathway.
If this is not what you asked then please ask again but include a little more detail on which parts ect...
on step 3 at 2:42 it says "solder two black wires into the hole next to the transistor and connect it to the transistor" and the picture shows that you have the negative leads and the transistor pin bridged, even though they're already connected on the pcb. i've made one without bridging it and it works just fine. im currently working on a bank of them and already have 3 together working great.
Alright, I understand what you are saying now. As you said they are already connected on the pcb but the extra solder ensures a good strong connection. But it will work without bridging the connections with solder as you said.
I'm asking you the wrong stuff. I ripped the parts out like you did. but what's that silver small capacitor doing on your picture there? blowing it up? lol
Its just there to show where the bigger capacitor would go. Also because its small and flat meaning that it was easy to scan into the computer as I did not use a camera.
So if the charge time is 1 second to get 320V, doesnt that mean u can rapid tap and get loud pops? maybe given 10 hours cut a hole in metal haha.
Thanks for this tutorial, i was looking for way to make this smaller, and faster :) And im guessing the diode helps protect the cap from risk of well.. you know...
If by "Rapid Tap" you mean rapidly charging and discharging then yes, you can do that. As for cutting a hole through metal it would only be possible if there was enough current to melt a hole instead it would erode the metal over time and you would eventually get through. I have however vaporized a hole in aluminum foil with 6 of these capactors. Aluminum foil is very thin which is the reason this happened but if it was sheet metal it would have just burnt the surface.
I also have hooked many together. sure u did parrell to ramp the amps up. But, 2 things.
1: Do you know how to hook a fuji? The led wasnt even on the circuit and i'm having problems with it.
2: Why cant u just hook the cap + battery directly to the amp, and screw the diodes and transistor? Last i thought this was a 1.5 - 320V transformer, and the other parts are just for too much into the transformer, (learned that )
Yes, the led will iight up when the charging is over. You can also remove the led from the board and extend it with some wire. That way you could mount this in a project enclosure and have an led indicater to show the level of charge.
I prefer a voltmeter over the led, its nice to have the led but the voltmeter has some advantages. You can tell if the battery's are low and the rate of charge so you could charge to a different voltage for more or less power.
I just wonder how you turn the DC current from the battery, to AC currnet for the transformer, and to DC again, for the capacitor, with only 2 diodes.
note that this message is not to criticase your work, but beacause I can't understand how it works :). If you reply, please be as thorough as possible cauz im only 15 ;)

This circuit has 2 diodes, a transformer, a transistor, a surface mount resistor under the circuit (or two I don't remember) they look like little black squares on the circuit. The schematic linked in the video description shows the entire circuit schematic so you could check that out.

why haven't you put the small capacitor that you find on the original board? and what does the capacitor changes?
G3NN4R0181195 1 year ago
I don't understand what your asking? The original board has many small components but many of those are part of the 2nd stage which makes the flash. The first stage charges the capacitor and that is what I hacked in the video to make it smaller. Anything not in the video is not necessary to make it work. Finally the big capacitor that was originally on the board is reused, watch the end of the video when I test it.
Hope this helps!

G3NN4R0181195 1 year ago
sorry to post again, im worried about my capacitors seeing as i have a very limited supply (only 50 x 330-400v 80uf) and ill probably not get any more for a long time as i stole them from a camera shop, is there a way to regulate voltage from the circuits cos im getting 500 volts from the two in parallel or is there a simple indicator circuit i can make to warn me that im overcharging my caps?. My electronics knowledge is pants. thanks
TeslaCoilArbiter 1 year ago
You cannot really regulate the voltage but you could turn it off. Use a voltage divider to drop the 500v bank to a lower voltage (1.5v). Then use that low voltage to turn on a transistor amplification circuit which would control a normally closed relay that sits between the battery and charger. When the bank gets to 500v the circuit would turn on and power the relay breaking/opening it causing the power to get cut thus stopping charging.
Ghetto but functional...
Halo2maniaccc 1 year ago
will it decrease charging time if i simply wire two of these circuits in parallel? that being said will i need more batteries (+1 battery per circuit) or will it just need one?
TeslaCoilArbiter 1 year ago
This is something many people have asked about and honestly you just have to experiment to find out what works. Get 2 circuits and try them in parallel, try them with 1 battery....2 batteries ect... Time the charging time and then compare it. When I tried to do parallel circuits I couldn't get them to run only one would turn on but others have gotten them to work. If both circuits work then yes charge time should go down because of an increased charge current.
I hope this helps!

how much input voltage can this lil board take b4 ir burns out? i applied a 9v to a camera board once and it fired in a sec. the max V i apply to my input on my mini coil gun is 4.5 (3x 1.5vAA) because i am afraid to burn it out.
shinobi1014 1 year ago
The board should be run at 3v to stay safe 4.5v doesn't give you all that much more. Anything more and the board will fry do to way too much power going through the transistor on the board. Keep it at its current voltage if it works and don't change it. If your in need of a higher power charging circuit you will have to build it I have several links and designs varying in difficulty and power I could send you just message if you want them.
I hope this helps!

@Halo2maniaccc 1 1.5v AA battery did not charge quickly. my bank is 3 in series 5 sets in parallel (15 caps total) voltage total of 990v. i doubled the batteries going into this board and it shot up to the range of 600V. i decided to double that with 6V in thats when it all went wrong. its there a way to make a decent portable DC cap-bank charger?? i was all over the ACG site with no luck. i cant make the boost converter and not all boards i have seem to have limiting resistors to remove.
shinobi1014 1 year ago
Google ZVS flyback driver and on google images to get the schematic. There are also youtube videos of it so look at those as well. If that design is too hard google single transistor flyback driver. The flyback can be taken from a crt monitor or projection tv and ALL off the components (two resistors and a big transistor) can be obtained from radioshack. That was the first driver I built and it charged MUCH faster than a camera circuit.

I do not really know, I have never come across a 7 pin transformer in these cameras. You best bet would be to go to Walmart or a local photo store and ask for their used cameras (they should just give them no charge). Go to many places and do that, and soon you should have hundreds of disposable flash cameras. One of those many is bound to be the right transformer! So my advice just keep looking for a 5 pin transformer.

Yeah, I had a really good five pin transformer on a camera, but in my infinite wisdom tried to get it of with a pair of pliers, breaking it.

Halo2maniaccc 2 years ago
hey. I found a huge capacitor from a big camera.. can I use a simple driver like the one on the video to charge it?
andretodopoderoso7 2 years ago
This circuit is essentially a voltage booster, 1.5v to 330v. Its nothing super special and its purpose is to charge a capacitor. So yes you can use this circuit to charge your big capacitor but it will only charge to 330v (if your cap is 330v+ it simply won't charge it all the way) it will also take longer to charge depending on just how large your capacitor is.
Hope this helps!
Halo2maniaccc 2 years ago
Oh ok.. The cap is thicker than my thumb! I fell of my chair when I got shock by it at full power! The only way to charge it is by using the original driver that came with it, but is to large to fit anywhere..
andretodopoderoso7 2 years ago
Yea you should watch out, capacitors that big can deliver enough of a jolt to cause irregular heart beats and eventually a heart attack.
You should be able to charge it from this charger, if its a basic capacitor then it shouldn't have a problem.
And if you think thicker than your thumb is big you should see some of the capacitors that I have. They are thicker then my forearm (3in diameter) and are about 12 inches long = to about 200 photo capacitors! This will not shock you it will KILL you.
Halo2maniaccc 2 years ago
lool where did you get those? you could build a power station in your room! Think my cap can´t realy hurt me like a police tazer.. by the way, where can i get one?
andretodopoderoso7 2 years ago
I got them off ebay, a guy had a used industrial surplus and sold them for next to nothing. Your cap can hurt you, a tazer is different it delivers high voltage low current to disrupt the nervous system and inflict pain. The capacitor delivers high voltage & high current in a massive jolt which can stop a heart. If you don't know what your doing don't play with these capacitors there is no second chance it will KILL you instantly.
Halo2maniaccc 2 years ago
When I say that the small capacitor will stop your heart think of it like this. You can throw a small wrench into an engine and stall it but that small wrench can't restart that engine. Your heart is the engine and the wrench is the capacitor.
BTW you have to use SCR's to switch these super big capacitors no switches can be used or they will vaporize the contacts & (possibly explode the switch apart) !
I take no liability if you hurt yourself using the information that I provided!
Halo2maniaccc 2 years ago
no no .. I don´t wanna mess with that kind of caps . when i ask you where can I get one, I was talking about the Tazer not the cap.. i´m ok with the size of mine :) ( cap ) xD

I really don't know how, if you have some extra electronics knowledge you could use a 555 timer to make the transistor oscillate. I can't really help with the schematic for that, just research it and build it. Go to walmart or any photo store and ask if you could have their used flash cameras. You are bound to find the right circuit. Kodak may have change the type of circuit in the cameras which I will have to check on.

utuber1418 2 years ago
I built this tonite. It is awesome ! I am potting it in jbweld. So I was wondering, what's the best way to switch that 330V? I tried (on the bench) using a household light switch, but the cap kept arcing. SCR maybe? Oh, I wanted to ignite my rocket igniters with it. Thanks for a great vid !
malleusdeus 2 years ago
The best way would be an scr but if its just 1 or 2 capacitors a push button switch from a hardware store will suffice. Make sure its in a nice plastic project enclosure, you don't want to touch hv leads! Igniting model rockets with this is the best it provides instantaneous ignition!!! Not the (1-2) second delay AA batteries give!!!
Halo2maniaccc 2 years ago
I never used AA batteries, always a 12V. This circuit doesn't work, but I think it's because it discharges so fast, it doesn't have time to melt the wire (igniter wire). I paralleled 3 of these caps, so there's plenty of energy, (E=0.5CV^2), and it drains 2 AAA batteries to almost dead after just 5 shots, so maybe I'll make a coil gun instead, and come up with another scheme for my rockets. Thanks again for a great vid.
malleusdeus 2 years ago
You must be using a different type of ignitor with thicker wire, I used estes model rockets, motors, and ignitors. With 4 capacitors it vaporized the thin wire in the tip causing the ignitor to make a large spark and loud pop. But if the wire is to thick then it will not work.
Halo2maniaccc 2 years ago
That's exactly what it is. I make my own igniters, never liked the estes. The pyro mix always falls off. I have a box now that works.
malleusdeus 2 years ago
Would you be able to use the output leads to create a continuous high voltage spark?
MattJBaugh 2 years ago
No, because it only outputs 330v. That's not high enough to see any arc. You would have to get a transformer that boosts the voltage way higher like 2kv minimum.
Halo2maniaccc 2 years ago
Also, would you possibly be able to post the colour code stripes of the 2 resistors (100 and 220) so i can identify them easier.
GenXCypher 2 years ago
with regards to the circuit, i have a few different types of camera, all containing 5-pin transformers with 3 on one side and 2 on the other. but they all sem to be wired differently. like different things go to different places than yours does. are all of the transformers the same, and can i just wire all of them the same as yours and they will work, or are some transformers differnet and will also need to be connected differently???
GenXCypher 2 years ago
If the capacitors are all 330v and the transformers are all 5 pins then they should be no different from the transformer in the video. They are basically 1.5v to 330v center tapped transformers, its nothing super special but if they are the same then my schematic will work assuming you wire everything up the same. Watch the transistor though if it gets to hot when soldering it gets destroyed!!! I did this many times....the frustration it causes lol
Halo2maniaccc 2 years ago
how do you know if its dead? lol
do you only find out when you fire it up and nothing happens?
GenXCypher 2 years ago
Well if it fails while its running you will smell a nasty burning plastic smell and a small amount of smoke will come from the transistor. After the smoke clears there will be physical damage on the transistor usually its split apart down the middle. It can however fail without the above and it just won't work when you give it power. If this happens make sure everything is wired right, like the diodes and capacitor. If it is and it still doesn't work then I would say it is a bad transistor.
Halo2maniaccc 2 years ago
after this mod, does the led still light up when the cap is done charging?
PyroTechyX 2 years ago
Yes, if you don't remove or damage the led during the mod it should light. Mine lights every time at 320 - 330 volts like it should. You can also de-solder the led if the led is burnt out and solder wires on so that you can you an external led in say a project enclosure or box!
Halo2maniaccc 2 years ago
Ty, and before you said you could also use 3v instead of 1.5v input.
What would the output voltage be and would iit still be safe to hook up to caps?
PyroTechyX 2 years ago
With 3v input the output voltage didn't change but I noticed a faster charge time because it drawing more current. If you simply increase the input voltage without changing wires or anything then it will work with the capacitor without problems. If you go to high on the voltage then you will hear a sizzling noise and smoke will come from the transistor!!!
Halo2maniaccc 2 years ago
silly noob question: does it matter which way round the resistors go? :S and if it deso, how do i find which end

Maybe different manufacturers use slighty different circuitry? ..and yours just does the job without the oscillator.
MattBlytheTheOne 3 years ago
The disposable camera circuit is very basic and universal but each manufacturer has their own little twist on it. Mine has an oscillator in it, without an oscillator the circuit wouldn't work. The transistor is the oscillator in this circuit. It took me forever to understand how these little circuits worked!
Halo2maniaccc 3 years ago
Current cannot be induced continously to the secondary winding using DC current. Househould ac current makes it convenient because its already oscillating at 60HZ (60 cylces per second. The camera uses ferrite, or powdered iron making an efficeient transformer with 80% turnover, probably oscillates at 40 to 200KHZ.
tangnatalaga 2 years ago
Yep that's the best way to sum it up. Except I remember reading that the camera circuit starts at around 40 - 50khz and dip's down progressively as the charge increase to around 15khz because it operates on feedback voltage.
Halo2maniaccc 2 years ago
I once made an oscillator to drive a cars ignition coil. They did not last very long. LOL They can't seem to withstand very high frequency current. It was fun tho.
tangnatalaga 2 years ago
If you used low current transistors that were made for low frequency applications then they won't last long. However if you use high frequency high current transistors it should last for a very long time. It could also depend on circuit design ect... Ignition coils are a lot of fun to play with!!!

there was a good spark across the cap but it didn't look like it had much power in it...?
MattBlytheTheOne 3 years ago
I was using an HD video camera but even then the camera can't pick up everything, the bang was much louder and the flash was brighter. It may not have had a full charge as I wasn't measuring it but it was more of a proof that the mod worked than to fully charge the capacitor.
Halo2maniaccc 3 years ago
hi, what is the nominal output voltage? and what voltage is the capacitor rated at?
/watch?v=N-Va2HE9ldQ
MattBlytheTheOne 3 years ago
The nominal output voltage is 330v from the transformer at 1.5v input. The capacitor was rated at 100uf at 330v.
I watched that video, it was quite interesting. I had never though about powering a mains light bulb direct from the capacitor!
Halo2maniaccc 3 years ago
and you say it signif. reduced the charge time? good work!
MattBlytheTheOne 3 years ago
Yep, the charge time was notably faster.
Halo2maniaccc 3 years ago
have you measured the output? the camera flash circuit reaches 330v via two coils acting like a tuned oscillator, if you are using only one transformer are the coils configured to reach 330v (or higher?)
MattBlytheTheOne 3 years ago
The basic transformer is 2 coils of wire wrapped around a ferrite core. The camera transformer has a specific ratio of windings between coil 1 and coil 2 (1.5 to 330). This provides the voltage boost and current decrease. So the transformer is only configured to reach 330v.
Halo2maniaccc 3 years ago
I thought in the original camera circuit it was the capacitor that limited the voltage across itself in this case 330v? and since the cct. is an oscillator it would continue to gain voltage so long as it had legs (current) or until it reached the caps nominal voltage rating? that's why people have been using the cct. to charge banks of large capacitors! Try measuring the o/p then you will know turns ratio on the transformer...
MattBlytheTheOne 3 years ago
I have attempted to charge up 500v capacitors with disposable flash camera circuits and the charging stops at 330v. The transformer is what determines the output voltage its all about that ratio of the windings. Large banks of photo capacitors in parallel just take longer to charge, in series the voltage increases across the capacitors but you don't need a higher charge voltage. Its sort of like battery's, series increases voltage, parallel increases the current.
Halo2maniaccc 3 years ago
If I want to charge a few capacitors in sequence, could I do it with these resources? I have about ten of these cameras that I plan to use for a coil gun.
Growf911 3 years ago
If by sequence you mean charge multiple capacitors in parallel (or series) then yes you can use the camera circuit to charge the capacitors. The more capacitors you add however will increase the time that the circuit takes to charge them. Just google flash camera coilgun, there is a ton of information on it.
Halo2maniaccc 3 years ago
What would the limit on the input voltage be?
Growf911 3 years ago
Normally the circuit is run at 1.5v but I have successfully run them at 3v, the extra voltage notably decreased the charge time. Don't run it higher than 3v though because the transistor will burn out.

Hi, i was wondering if someone here could help me...
i would like to use a thyristor to discharge a flash capacitor, i just tried it a minute ago, it discharged once, when i pressed the button, but now there is a dead short across the thyristor (i take it thats what the pop was). could someone tell me what i did wrong?.
i put the cap (-) on the cathode along with the (-) from the 12v battery, i put the cap (+) through coil to Anode, and the battery (+) through a 1k resistor, switch, to gate.
HVdischarge 3 years ago
It sounds like you may have burnt out your thyristor. I have a huge one rated for 250 amps continuous at 500v (7000 amp peak for 2ms) and I have hooked it up in the exact same manner you did without any problems. The capacitors that I hooked it up to were also 100 times more powerful than a flash capacitor. The thyristor was probably not rated for such a high voltage and current. I could be wrong but this is just the most logical guess that I could come up with.
Halo2maniaccc 3 years ago
thanks for the reply, came to that conclusion, when i replaced the thyristor, and added a 330ohm resistor, i repeatedly charged and discharged the cap, until the camera charging circuit stopped working :-( lol.mine was rated at 8amp @ 800v , i suppose i better see how much a descent one will cost :-/. thanks

Halo2maniaccc 3 years ago
Can you connect multiple transformers to increase capacitor charging? like the picture that showed input and ouput wire. Connect another tranformer to input and then connect it to the output. (Put it in series I mean)
Ex: input----transformer----ouput----input----transformer---output----Capacitor.
Is this correct?
1016JP1 3 years ago
I don't think that would work because each circuit would not be synchronized with the others so you would have a really weird output. This can be done with batteries obviously but with using multiple transformers in series it would be really hard to get each one synchronized and pulsing at the same time. With a 555 timer you could do this but the camera circuit is based off feedback so the charging frequency changes based on the charge level, initially its like 40Khz and it ends at like 10Khz.

"Why cant u just hook the cap + battery directly to the amp, and screw the diodes and transistor? Last i thought this was a 1.5 - 320V transformer, and the other parts are just for too much into the transformer...."

tonedizzle6289 3 years ago
The transformer uses DC current which is steady direct current with no alternating or switching, AC current alternates 60 times per second. The current must alternate on and off into the transformer in order for it to work. The transistor switches the DC current on into the first transformer coil, then it shuts it off which allows the energy in the first coil to move to the second coil where the voltage is increased. the diodes then rectify the output to be 330v DC. PM me if you need more help!

why do u add an extra diode ....there already is one on there
and besides that, i think the way ur cutting the board, is cutting off a small capacitor from between the transistor pin3 and battery minus, does that affect performance?
romnite 3 years ago
If the extra diode is not added the charger will turn on and the led will shine but it won't charge. I am pretty sure that the extra diode prevents the capacitor charge from flowing back into the transformer which will prevent it from charging. Without the extra diode the circuit will not charge the capacitor. As for the capacitor I thought the performance after I cut it off was better but I can't see a little tiny capacitor really affecting performance that much.
Halo2maniaccc 3 years ago
no but really the circuit already has the diode to rectify the current from the transformer and to keep the capacitor from discharging backward...i gues if u tried the set up both with and without the extra diode and it only worked well with the extra diode , then sumthing wierd is going on

I had tried it with and without the extra diode and it seems to only work with the extra diode.

why do you need to bridge the 2 neg wires to the transistor if they're already connected on the pcb
eggman01010101 3 years ago
Are you talking about bridging the transistor and transformer? They are not connected if you look closely at the pcb the blues lines are the electrical pathways not the dark spots. There is no blue line going from the transistor to the transformer pin so you must solder in a wire as a pathway.
If this is not what you asked then please ask again but include a little more detail on which parts ect...
Halo2maniaccc 3 years ago
on step 3 at 2:42 it says "solder two black wires into the hole next to the transistor and connect it to the transistor" and the picture shows that you have the negative leads and the transistor pin bridged, even though they're already connected on the pcb. i've made one without bridging it and it works just fine. im currently working on a bank of them and already have 3 together working great.
eggman01010101 3 years ago
Alright, I understand what you are saying now. As you said they are already connected on the pcb but the extra solder ensures a good strong connection. But it will work without bridging the connections with solder as you said.

PhxSt0rmz 3 years ago
If by "Rapid Tap" you mean rapidly charging and discharging then yes, you can do that. As for cutting a hole through metal it would only be possible if there was enough current to melt a hole instead it would erode the metal over time and you would eventually get through. I have however vaporized a hole in aluminum foil with 6 of these capactors. Aluminum foil is very thin which is the reason this happened but if it was sheet metal it would have just burnt the surface.

1. I have only used a kodak funsaver so I do not know how.
2. I sent you a pm because there is not enough space to tell you here.

does the led light up when the cahrging is over?
silverska8er 3 years ago
Yes, the led will iight up when the charging is over. You can also remove the led from the board and extend it with some wire. That way you could mount this in a project enclosure and have an led indicater to show the level of charge.
I prefer a voltmeter over the led, its nice to have the led but the voltmeter has some advantages. You can tell if the battery's are low and the rate of charge so you could charge to a different voltage for more or less power.

Good Idea!
I just wonder how you turn the DC current from the battery, to AC currnet for the transformer, and to DC again, for the capacitor, with only 2 diodes.
note that this message is not to criticase your work, but beacause I can't understand how it works :). If you reply, please be as thorough as possible cauz im only 15 ;)

it also has a transister which acts as a switch

Are you talking about the coil and barrel?
If so you would hook them up to the capacitor with a switch.

where do u hook up the coil and the tube for a coil gun
