Title: Schematic Diagrams of Commercial Products (Reverse Engineering)
Post by: aleid on December 17, 2007, 02:24:16 14:24
Hello everybody,

One way to unleash many tricks of good quality designs and projects is to reverse engineering a commercial product. From my experience, reverse engineering is a very complicated task unless you got the schematic diagram which then the life will be much easier.

I would suggest that as we have cracks for softwares we can have a portal for reverse engineered schematic diagrams!

I have been looking for some since long time but really hard to find. I have done some when I was working with Siemens but unfortunately not anymore. If anyone got any schematic diagram for any of the commercial products then it will be very nice to share it.

Cheers,

Hi,
Before starting manual reverse engineering, I suggest to check if Integrated Circuits and/or components are standards reference or 'special'. I spend hours in a temperature regulator until I got stuck on an unknown IC, sticking me at that point.  Hope my bad experience will avoid you wasting your time in the same stupid mistake...

Reverse Engineering has a logical methodology and steps to carry before tracing any circuit. In some circuits, you do not have to know what kind of IC it is! Depending on your electronics-knowledge about the overall function of the circuit, sometimes you can define this IC as a block which has certain Input and Output. If you know the Input and you know the output (which is an input for another block of the circuit), then you can predict the function of IC even if it is unknown.

I have said earlier, reverse engineering is quite complicated. But, it is a fact that doing it worth so for the result(Just look how the chineese are doing it and how they cope up with the world technology). It turns out sometimes that it was a waste of time.

Cheers,

Hi!If you need(badlly) a service manuals of any producer/produces-maybe I have it-just post model & producer-and I upload them on rapid(Cant help everyone :'( but someone -yes :)).With best wishies...

I think reverse engineering is really hard to do with the recent systems. PCB with so many layers, SMD parts which are not marked, etc.
