Build an USB LED light from an old webcam

Today  over at instructables is going to show you how to build a USB LED light from an old webcam.


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
