    Hi everybody.

    I want to build a circuit for my car that shows me the front and rear camera in the same screen (splitted).

    Is this possible with a simple circuit?, any ideas about how to build the circuit?

    Thanks

    That is a complex function that can't be done with a simple circuit.
    To start, you need to know what the video format is.

    Edit: You best bet may may be to buy a split monitor such as one of these or this.

    You could program it, I recommend windows media foundation for the library. Actually doing it in hardware is old school, and really cool if you did it tho. :)

    Program what?
    Are you proposing putting a computer in the loop?

    I dont mean putting a computer in the loop, i mean just using a computer by itself. :)

    When CBS introduced the quad split screen, what most people don't realize is that it was a purely mechanical effect. The took the cases and frames off of four monitors so the screens could be pushed as close together as possible, and pointed a camera at the assembly. An all electronic split screen came years later. I installed the first one in Columbus.

    All RCA connectors implies all NTSC composite video, which makes an all electronic split screen very easy with Maxim chips. BUT ... the two cameras must be synchronized, and most small low cost cameras will not sync up to an external signal. So if you don't want to do this with a pc that has two video capture cards, then you need to buy a split screen device that has frame synchronizer built in.

    I fail to see how that helps solve the OP's problem. :confused:

    If its a crt, cant you hack the position of the ray gun? Since its signal controlled, maybe you affect the signal to do it.
