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.

Features:

- 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

Picture of Tools and Materials
Tools:

- Rotary tool
- Hot glue gun
- Soldering iron
- Solder
- Cutting pliers
- Wire strippers
- Torch
- Multimeter (for testing voltage and circuit continuity)

Materials:

- Old Memory USB
- Rigid copper wire (12 AWG)
- Heat shrink wrap
- Ethernet wire sheathing
- Wire
- 2-pin connector
- LED
- resistor (220 Ohm)
- Plastic cylinder (optional, you can find it on any old plug)

Step 4: Checking connections to prevent short circuit

WARNING : This is the most important step, because this will prevent damages to the laptop.

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 6: Soldering to USB base

- Fold copper wire as shown on the photos
- Solder copper wire to the USB base as show on photos

Warning: :Confirm that all pins are free and are not connected between them.

I have the same problem, I often take my laptop to bed to do a bit of work beofre going to sleep, my wife keeps complaining .... you know the story ;-)

I came up with a similar solution, mind you, the cable I used was way longer. your solution is much, much better !!

Elegant, compact and very practical. Well done sir

Fantastic, I'm making a few of these this weekend. I've needed them for a while but have been too lazy to find a cheap place to buy them.

One thing I have on my prototype right now is a light guard to prevent the LED from shining light into the user's eyes. Right now, plugging it in lights up the keyboard well, but the LED is blinding. I suppose I could just coat one side of the LED in something opaque, or even reflective.

If the LED socket was longer, you could just cut the underside away to expose the LED while the top side would block extra light.

Very cool...
However, my MBP has a backlit keyboard.
But seriously... very cool.

for better keeping of LED-light form you can solder paper-clip to USB-connector and put it alongside of wires, then put on the heat-shrink tube and to heat it by cigarette-lighter

Sorry if someone has already told you this but, it's called a rotary tool. Great project. my laptop has stacked ports on both sides so i made two so that each side of the keyboard is illuminated.

Did you use an rgb led?
hpsaturn (author)  Adam Manick4 years ago
No, in the photos I show 3 different LEDs because I made it in a way that they can be interchangeable. Anyway, you could use a 2-pin or 3-pin RGB LED, but those would be differents projects.
