I am a big fan of the old Japanese board game Go. Some time ago I wanted to get my own Go game, consisting of a Go board (goban) and black and white stones. Unfortunately, I found out that wooden Go boards are quite expensive, by far exceeding the price range I was willing to pay. Actually, gobans are quite a simple piece of equipment. It is nothing more than a (wooden) board with a grid of 19 x 19 lines on it, why should I pay over 100 euro for it? So I decided to build my own and just buy the stones, which are cheap to come by.
This is another old project that I made a while ago. I have to admit, the idea itself is stolen from instructables.com and you can see that the outcome looks similar at first glance. But I wanted to take a different approach. While I really like the shoji-design, I wanted my lamp to be more solid and long-lasting. Besides, I preferred the size (and ratio) of the DIN-A4-format, so that I can easily replace the paper without trimming it first, in case it gets damaged or i want to change the color. It has a beautiful ratio (297 / 210 = √2). The length of the sticks within the frame are chosen in a way that the rectangular pattern on the frame also has a ratio of √2.
