.. so you do not have the cellphone yet. One advice: do not buy one for this project. Spend the money for **broken link removed** if you want to continue working with pics. It has a debugger and logick analyzer integrated.. you'll need them.
I gotta say no. You've been struggling with basic electronics & programming for years, never seem to actually test what you're working on, don't appear to read, understand or follow replies and are easily distracted.
This sort of project requires the opposite set of skills, and someone with those skill would be very unlikely to attempt it.
The S3520 is a feature phone, ill suited to this sort of project.
What exactly is the plan? Disassemble the phone so that the LCD is at your face and the rest of the phone with camera is attached to your back? If you already have the phone, of course you can experiment with it.. but you are pretty much on your own.
sahu: what is this project for? Why do you want to build it yourself? Why don't you buy a working cctv system? You can find cameras with sd-card recorders and monitors. Building your own will be more expensive and very difficult project.
