This is a small project that I worked on last year. I have a desk made of dark wood, and it was very difficult to see what was inside the bottom draw. I put together a simple circuit with the schematic below - something which lit up a few strips of LEDs using a magnet stuck to the side of the door to switch a transistor on/off.

 

I also made a video with my old iPhone 3GS and uploaded it to youtube.

What blew my mind was the popularity of the post - in a few weeks, over 15000 people had seen the video, and the project was picked up by Hackaday and LifeHacker.

This has been a great inspiration for me to share the projects I am working on.
