I took about a printer someone was junking, to see what it's like and what I can get out of it. I have pictures here with a bunch of questions(this is the beginner forum after all
):
Picture 1:
- Near the top left there are little coiled packages. Are they just standard inductors?
- Near the top left, there are these little bulb things. What are they? They don't seem to be LEDs, one of them is fairly black on the inside
- In the middle, is the square thing a transformer? It's a bit different than the ones I've read about but it seems to match some I see online
Picture 2:
- Laser diode? There are three pins on the back. I think I may wait to play with that until I can be safe
Picture 3:
- Assuming the large part is another transformer
- What is the thing on the bottom left? The silver top with black surroundings. There is a side profile picture of it in picture 4
Picture 5:
- At the bottom left, there are silver resistors. What would these be called? The stripe pattern is different than I am used to
- At the bottom right there is a device that appears to have something go in the middle and interrupt the signal. Is there a name for these?
Picture 6:
- What's the thing on the left labelled as CHG? Is it a standard component or some custom packaging?
- The two square wound things on the right look a bit different than the other transformers. Is it safe to assume they are still transformers?
Picture 7:
- Is it normal to be able to get these kinds of LCDs to work? Or do they tend to have some native encoding/signal that proves tough to figure out? I may try to look up or figure out how to make it work if it's not nearly impossible
Picture 8:
- Mid left, what are those two coil things that are placed together? Is this another form of transformer?
- There seems to be another big one to the right
Picture 9:
- There is a big of darkening on the board under these resistors. What causes this? Heat? Chemicals from manufacturing?
