In my new house I have a stair going upside in the bedrooms. There, I had only one light source but I needed to have enough light to cover the whole stairway. So, inspired by a lamp design I saw on the web, I decided to make my own design and made three lamp to hang on the wall. It is made of wood and iron with hammered effect, so it has a rustic appearance matching the rest of my furniture.
A "furniture-compatible" DIY RGB lamp I made. it uses Arduino-based hardware. The whole project is DIY, both in the microcontroller part and in the lamp part.
