Is this a CMU cam? Can I do good use of this in my boebot?

I found this from a toy that is like a karaoke with mike and this camera looking thing. I made the camera working which is connected to the whole thing. If someone could help me to get thing working with my boebot. dragging a cable is just fine I am just a beginner and have no idea about wireless stuff. thanks for the replies. -bert (aka noxnox)

    It's probably different. A cmu cam is made to send messages made for the basic stamp. The camera you found could probably be useful though. I don't know how myself, but you can probably attach it to your tv for security (if you want it) or, if you can find a way to make it wireless, you could attach it to your robot and watch what it does without being near it. Also, you could post videos online showing how it works. See if you can find an attachment to make it work on your tv, and, if so, the next step would be to try and get it on air.

    Yeah! thats what I'm looking for I think its the same with one of the accessory offered for boebot but this don't have additional circuits on it to be useful in basic stamp programming. I hope someone could point me to a diagram of the needed circuit. If I made this work wireless with my boebot I just need to teach my boebot to walk the ceiling and lexy(i named my boebot) can be a boebot gecko!

    It's probably an NTSC-output TV camera. Check the frequency printed on the crystal (not visible in your photos). If it's an integer multiple of 3.579545 MHz, that's virtually certain to be the case.

    That on the shinny silver thing on the back of the cam. what is NTSC? If you could point me to a diagram from which I could make to have an output video going to my TV it would be much appreciated.

    14.318 = 3.5795 x 4, so it's bound to be NTSC. My guess is that the video signal is between the yellow (center) and black (shield) wires, with power going to the red (+) and black (-) wires.

    I have no idea what voltage to apply to the supply leads, though, especially since it looks like the regulator has not been populated on the board. Therfore the supply voltage may be critical. If you have a variable-voltage power supply, start at 0V and work your way up slowly until you see a picture. Or, if you can remove the lens, there may be a part number on the sensor chip, which will give a clue as to the proper supply voltage — probably either 3.3V or 5V.

    NTSC stands for "National Television System Committee" and refers to the baseband video output that is standard in the U.S. Baseband video is not modulated RF, though, and cannot be fed into the antenna terminal of a TV. If your TV or monitor has a yellow RCA (phono) socket labeled "video input", that's the right place to connect your camera's output.

    Cameras like this are not compatible with the BASIC Stamp. Since this is no longer a BASIC Stamp question, perhaps the moderators could move this thread to the Sandbox.

    Phipi! thanks a lot! thats really helpful. but how can I connect it to the video input of our tv? is that what the yellow wire for? but isnt it that there are 2 connection in a RCA/video input? How can I put this to the sandbox.

    P.S. Thanks again for your time.

    yes the yellow wire is for video. to conneect it to your tv - connect the yellow wire to the pin part of the RCA plug and connect the other part of plug to the to the ground or black wire on your cam.

    This thread is being moved from the BASIC Stamp Forum to the Sandbox Forum.
