Intro: Build an USB LED Light From an Old Webcam
If you have an old damaged webcam, you can use it to make an USB LED light.
Step 1: Components and Tools
- Soldering iron
- 5mm Drill
- 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.
