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