Laptop webcam to usb

Former Member
Former Member over 14 years ago

Hi

 

I have an old ACER Tm 7514WSMi laptop. its broken, so I took its internal webcam from it. Iv heard that most of laptop webcams are usb wabcams.

 

So from my webcam comes 5 wires. red, blue, orange, and green and yellow twisted together.

 

Inside usbcabe are only four wires, white, green, black and red.

 

So how could I connect those wires from webcam to usbcable.

 

My webcam detects when I have turned it around, pointing away from laptop unlike most of webcams.

My webcam has a swich insede, which detects when its turned. so I guess that one of wires is for it. I cant trace which one of wires goes to that swich.

 

so hos should I connect this to usb cable. Which color goes to which?

    I have done this successfully. Mine only has four wire. The ones twisted together will be the USB data lines. You will need to work out what ones are +5V and gound. Maybe you can work it out by inspecting the board (Or the main board of the laptop).

     

    On mine the +5 and ground wires were coloured Red and Black but the Black one was +5V. I had it around the wrong way at first and the camera got quite warm but was not damaged.

    Thanks for reply,

     

    Its really hard to see anything fron that boad.

     

     

    I  opened  my webcam, and here is a picture. that boad if guality is not good enough, I have a picture on my webserver (wount be there forever...)https://jarmo.homelinux.org/pictures/Webcam.JPG , sorry, no http, only https, and self signed cert.

    Its hard to teke picture from that board, background and everyting are basically made with same colour. In that picture you cant see wires , so I wrote colours to that connector.  I hope that you could take a look.

    My biggest consearn is that if I connect it wrongly, could it destroy my laptop?

    You could most likely find the ground connection by measuring with an ohm meter to the metal around the screw holes.

    Also there is a ceramic capacitor near the connector (Has a + sign at one end?). It is probably the input decoupling capacitor. So check if each side of it is connected to one of the input wires.

     

    If that works out then you should know how to connect the power supply correctly and you will be able to hook it up to a USB plug. If it won’t work when plugged in then reverse the data lines (the twisted ones).

    Maybe don't try it on your favourite USB port until you confirm it is working.

    orange and blue are connected to those screw holes. and seems to be connected to that ceramic capasitors other / "not + side"

     

    Red seems to be connected to that ceramic capasitors + side.

     

    In usb cable are four wires; Red, Black, Ehite and Green.

     

    So are Red wire +

    Black is -               

    Green and white are datalines in USB

    Green and yellow are data lines in camera

     

    Is that correct?

     

    red from USB  to  red of camera

    black from USB  to  Blue and yellow

    white from USB  to  Yellow from camera

    green from USB  to  green from camera

     

    Does this look right?

     

     

     

    EDIT: I connected orange and blue to "-" in power supply and red to "+" in powersupply. I set it to output 5V (DC)

    That cam used 0.06-0.07A, which seems quite right for me.

    You can't really say if it is right or not until you try it and see what happens. If you have a USB Hub try it though that.

    But my basic idea of USB cable is right?

    Red is +

    Black is -              

    Green and white are datalines

    Right?

     

    So if I connect it wrongly it woun't blow up my computer, only that usb port its connected to.

    Yes that is the right pinout for USB.

     

    I think it would be unlikely to damage the USB port if connected wrong. The power lines are normally protected by a PTC or similar.

    I REALLY need help, my camera looks like the other guys and is a Acer "Camellia_2" from a acer laptop But it has whole different wires! it has Black, White, Lime Green, And Pinkish Red. I tryed connecting red to red, green to green, black to black and white to blue but the camera always gets hot if the usb black is attatched to any other color but the red from the camera.... i tryed other various combinations and nothing happens.. The only major thing i noticed is that when i hook the red from the usb to the black from the camera the green light turns on..., but any other combos nothing happens.....
