Build an USB LED Light From an Old Webcam




Introduction: Build an USB LED Light From an Old Webcam

About: My name is Duarte Cancela, I'm from Portugal and I'm also a science and art's lover.

If you have an old damaged webcam, you can use it to make an USB LED light.

Step 1: Components and Tools


  • Soldering iron
  • Driller
  • 5mm Drill
  • Multimeter
  • Hot glue gun
  • Adhesive tape
  • Miscellaneous tools


  • Old webcam
  • 1 - 5mm LED high bright (white or other colour)
  • 1 - Resistor 200 Ohms

Step 2: Disassemble the Webcam and Get Ready To

Disassemble the webcam and remove the pcb.

Use the lens support to fix the LED, in my case I needed to make a 5mm hole with a driller.

Step 3: Solder the Components

Solder the 200 Ohms resistor to the LED.

Step 4: Find the 5 Volts Wires and Make the Connections

Cute the USB cable end connector and connect the cable in your PC to find the 5 Volts wires.

Then, connect the 2 wires (in my case the black and red) to the LED, the positive cable must be connected to the anode LED terminal (the big terminal), in my case it's where I soldered the resistor.

Protect one of the terminals with adhesive tape or a small piece of plastic wire cover to avoid a short circuit.

Step 5: Assemble the Components and Mount the Webcam

Fix the LED to the the lens support with hot glue and mount your new webcam LED light.

Step 6: ​Connect It in Your PC USB Port and Voilà

Connect it in your PC USB port and voilà, use your new cheap LED ligh.

    Very nice Bling factor.

    These should be rocking with 1W or 3W Luxeon Stars.

    Very cool! I may have to try this...I think I have the parts laying around.

    Thanks for sharing!

    Black hot glue would work well for this, to avoid light spilling out the cracks in the case

    if you install this and to prevent mucking up you computer ensure that you insulate effectively the connections. As shown this will damage you computer or 5v supply

    Take a look on the next photo, the entire terminal was isolated with adhesive tape.
