Well, not supposed to be a practical project but I was thinking of making one for a science fair. By the way thanks!Possible? Of course. Practical? Not even close. Why would you want to build something so complex that you can buy for next to nothing?
So, would extremely low density data accomplish the goal? I mean, if you could just put a few bits on the disc, would that be acceptable? I could see having a chance if you could aim a laser to within, say, a half inch block on the disk as a single bit. It would still be a BIG project to achieve that mechanical accuracy, and make all the laser control circuits. Merely hard instead of nearly impossible.Well, not supposed to be a practical project but I was thinking of making one for a science fair. By the way thanks!
Hi guys, is it possible to create a CD reader/writer at home?
If you mean ,that you want to make the CD drive mechanism ,then I am sorry you can't because that kind of work is not done by humans its rather done by machines.I think it maybe is possible but I want to ask first, just in case of hazards.
Just don't look at the laser.just in case of hazards.
Well, such a project would involve the use of IR lasers that exceed the limit of safety for items such as laser pointers, etc. As such, that would place the project in a "hazardous" category, which also puts the project beyond the scope of the forums.
You could put an eye out with that!
But seriously, you wouldn't be able to see the laser light with the naked eye, so you wouldn't know for sure whether you were being exposed to it.
Also, the project would have to be completely enclosed in an opaque material (like steel) so that the laser light couldn't escape. This limits the usefulness of the project from a science fair aspect as the viewers would not be able to see the "inner workings" of the device.
