Reuse laptop webcam

This is a guide on how to reuse laptop webcam.

Laptop webcams are the easiest to salvage component from a broken laptop. You can reuse only the webcams that are connected to the mainboard through a usb connection.
I successfully converted the camera from an MSI MS-1682 cx600x laptop.

These are the easy steps on how to reuse laptop webcam:

1. Remove the camera from laptop screen

In order to get to the camera, you will have to dissasemble the laptop screen. Before starting work, you should search on
youtube a laptop dissasemble guide for your specific laptop model because there is a good chance to find one.

If you cannot find a video tutorial try this:
– make sure the laptop is not plugged in and the battery is removed
– open the laptop lid
– look for screws on the top cover (they may be covered with rubber )
– remove the screen basel
– disconnect the camera

2. identify the camera pinout

If the camera connector has markings beside it, you are lucky.
Many camers  has a five pin connector, usually it also has two twisted wires on the middle of connector. That wires are connected to data plus (D+) and data minus (D-) pins.
In one side of the connector, wil be two wires that are connected to Ground and in the other side there will be one wire that is connected to Vcc.
In order to find the Ground pind, you can use the multimeter (set on continuity/diode mode) to test the continuity between the big non-isolated area on backside of the camera and the pins.

3. connect the camera to usb

These usb cameras can work on 3.3V or 5V and if you cannot determine the voltage, it is better to try powering your device with 3.3V first.
We need an usb cable and a voltage regulator.
In order to reduce the voltage, we will use the LM1117T voltage regulator and two 10uf tantalum capacitors.
With the printed side towards you, and the pins down, the LM1117T pins from left to right are: Ground, Vcc out (output), Vcc in (input).
Connect one capacitor between output and ground and the other between input and ground paying attention to polarity (The longer pins on capacitors are the positive ones).

After the connections were made, you can connect the usb cable to a laptop and test if it works.
