I have an old damaged flash drive that I don't want to throw away, what can I do with it?
Thinking about the nights my girlfriend was bothered when I had to work at bed with lights on, I decided to bring it to life as a Laptop light. Then here is what I did,
How to make a laptop USB Light from reused materials.
- With LED socket (For easy replacement for any LED)
- Small, very portable
- Custom angle adjustment
- Very cheap, since most materials are reused (it won't cost more than $2)

Step 1: Tools and Materials
- Rotary tool
- Hot glue gun
- Soldering iron
- Cutting pliers
- Wire strippers
- Multimeter (for testing voltage and circuit continuity)
- Old Memory USB
- Rigid copper wire (12 AWG)
- Heat shrink wrap
- Ethernet wire sheathing
- 2-pin connector
- resistor (220 Ohm)
- Plastic cylinder (optional, you can find it on any old plug)
Step 2: Preparing USB Memory
- Remove board components (Photo 2)
- Round the edges (Photo 3)
Step 3: Socket Building
Step 4: Checking Connections to Prevent Short Circuit
Confirm that all pins are free and are not connected between them. Please see the diagram and photo below which shows the five pins to test.
Use the multimeter and if test fails, go back to step two.
Step 5: Building the LED Socket
- Insert the rigid copper wire into the ethernet wire sheathing
- Peel the rigid copper wire at its base
See photos for details
Step 6: Soldering to USB Base
- Solder copper wire to the USB base as show on photos
Warning: :Confirm that all pins are free and are not connected between them.
Step 7: Connecting LED and Resistor
- Connect resistor to GND (See diagram in step x)
- Connect LED red wire to VCC (See diagram in step x)
Step 8: Hot Glue Gun
- Cover the resistor with the hot glue gun
- Insert platic cylinder recovering the LED socket
Step 9: Heat Shrink Wrap
- Use torch to heat the shrink wrap
- Insert the heat shrink wrap over USB base
- Heat again.
