- But if you put it back together will it work? Or will it shock you?(7 votes)
- It all depends on how you disassembled the product. If you were careful enough to not damage any component, it should work like before. Manufacturers assemble it like this before you buy it.(11 votes)
- How many resistors and capacitors are in the new camera?(2 votes)
- Actually both circuit boards are the same, (manufactures rarely change it as long as it's working fine) . As seen in the video the only changes are for reduce in production costs. That's normal, mainly for electronics.(2 votes)
- why are batteries placed the way they are, like + - and - + ?(0 votes)
- Electricity, as you probably already know, is the flow of electrons through a conductive path like a wire. This path is called a circuit.Batteries have three parts, an anode (-), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a traditional battery) are hooked up to an electrical circuit.The chemical reactions in the battery cause a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. You can think of this difference as an unstable build-up of the electrons. The electrons want to rearrange themselves to get rid of this difference. But they do this in a certain way. Electrons repel each other and try to go to a place with fewer electrons.In a battery, the only place to go is to the cathode. But, the electrolyte keeps the electrons from going straight from the anode to the cathode within the battery. When the circuit is closed (a wire connects the cathode and the anode) the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. This is one way of describing how electrical potential causes electrons to flow through the circuit.However, these electrochemical processes change the chemicals in anode and cathode to make them stop supplying electrons. So there is a limited amount of power available in a battery.When you recharge a battery, you change the direction of the flow of electrons using another power source, such as solar panels. The electrochemical processes happen in reverse, and the anode and cathode are restored to their original state and can again provide full power.(4 votes)
- does the quality of the product reduce if the upgrade is done? or only the size of product reduces?(1 vote)
- I do have one question, how come he couldn't watch the video he made in reverse so that he could put the camera back together?. I get that it would be confusing and buying another would be easier, but still.(1 vote)
OK. So I took a part two of the exact same camera. And I did it, to be honest, because I took the first one apart to identify the parts inside of it and had some issues getting it back together because some of the screws just were stripped, and it did not want to go back together. And so I bought another one and found out something kind of interesting. So this camera, a lot of products go through different revisions that don't necessarily show up in model numbers. So that means that the manufacturer may have found a better way or a less expensive way to produce something. Or it could be that they just found a cheaper way to produce something and were able to improve their margins. And so with this camera being so low cost, I'm sure the margins are of a great deal of interest to the manufacturer. If you look, this one says version 3.8 and this one says version 3.3. So this is an older version. This version has an epoxy potted central processing unit or CPU. And this one has just a plastic cover over it. So the plastic cover may not be as robust as the epoxy potting. I'm not sure, but it doesn't look quite as stable. It would be harder to mess up those wires. And when I pop this off, the wires are clearly messed up to the CPU there. And obviously, the boards are totally different colors. I guess that lets the manufacturer know that they are different revisions. If you the flip the boards over, you can take a look at the-- let me zoom in just a little bit on this. You can see the charge couple device or the light capturing device is very different. So this one looks larger, more robust. This one looks a lot smaller. So it appears that what they've done this is a cost reduction, probably a reason to change. Also, the onboard memory is a different manufacturer. So it may be that this memory is less expensive, the new memory. This board doesn't need this capacitor. And so perhaps this electrolytic capacitor was a cheaper way of storing a charge during the photo process. And if you look at the lenses here, this one's got a big lens cover over it. And this one has no lens cover over it. So that probably added cost. I don't believe that's actually the lens. I think it's still that tiny little thing that you see inside this one here. But it looks bigger with that. And they probably just got rid of it to reduce cost. So anyway, that's the difference between one of the earlier iterations and one of the later iterations. But as far as consumers go, you wouldn't know any difference at all when you bought the two cameras because they're virtually identical on the outside.
