This night lamp isn't only cheap, it is also very easy to make. All you need are cheap and easy to find electronic parts and a little of soldering knowledge.
If you are one of those who has a roomate and need to work on night but he/her needs to sleep, this lamp is very useful for you. All you need to do is connect your lamp, turn of the light and your roomate can get some sleep, and you're still available too see your keyboard!!!
Step 1: You need:
- Hot glue gun (optional)
- Soldering iron
- Welding grease
- Cutting pliers
- 1 USB male connector
- 1 white light LED
- 1 120 Ohm resistor
- About 20 centimeters of cable for speakers
- Wire of a notebook
- Same size of heat shrink tube (5mm in diameter)
- A small piece of another heat shrink tube (around 10mm in diameter)
A tip from my brother: sanding the LED so the light spreads and it will look brighter
