Micro Camera Circuit Mod!

This is a very simple mod for a KODAK FUNSAVER disposable flash camera. It allows you to take the large bulky circuit that you get and turn it into a 1.5cm by 1.5cm circuit that charges capacitors faster than the unmodded circuit.

In some places the video is kind of fast so you may need to pause to read the directions.

If you have an questions you can send me a pm. I am also working on a 4hv wiki How to article for this which will be very clear with paragraph explanations for each step.

Here are the links to the schematic, and a picture of the circuit assembled.

@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?

[Halo2maniaccc]

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.

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 ! ;)

[Halo2maniaccc]

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 !

Thanks for watching!

[Halo2maniaccc]

You should be able to. Some people have gotten it to work while others have had issues with it. Tinker with it, it may or may not work.

what is the code of the transistor that u are using?

[Halo2maniaccc]

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.

how to do it with a 6 pin

[TheKaos90]

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

[lowang438]

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?

[chilidress]

@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

[chilidress]

i have a 4 pin transformer what do i do now?

[coatduck]

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

[Dem0D1ck]

This is an Excellent circuit.

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.

Other than that, excellent circuit mod.

@ExplosivetipStudios try my latest video see if it helps with your type of circuit.
