A wall shelf with a hidden LED backlight and a wooden touch tile that switches it on. The original is solid oak and costs about €300; I rebuilt it from a single pine panel and two AliExpress parts for less than €50. Measurements, cutting layout, how the light is hidden, and the one problem I have not solved yet.
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.
