Building a simple goban (Go board) DIY

goban_asm-wgoban_asm-draftgoban-finished1

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.

Raspberry Pi Case DIY

I finally got myself a Raspberry Pi and it obviously needs a case. (By the way, it runs the ARM version of Arch Linux, naturally.) Of course I wanted to build one myself, rather than buying one of those boring cases that almost cost more than the device itself. I already had a vague idea about the concept but nothing solid yet. The concept had to be simple (but solid), because besides a Dremel and an electric drill I only had standard tools at hand. (You do not even need a Dremel if you have a small saw instead.)

DIY: Building a Japanese shoji-style ambient lamp – the nerd way

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.

RAID5-Server to hold all your data – the NAS alternative with software RAID

This was an old project of mine. A few years ago I had a huge load of data comming in (~4 TiB) and the amount of storage I needed suddenly more than dubbled. Until then I was using two 1.5 TB HDDs which I mirrored by hand using rsync, because I’m paranoid of loosing data. It was annoying to always copy all data to each disk to have redundancy – and certainly not a smart solution. Now that data wouldn’t fit onto the two disks anyway, so it was time to think of a new solution. I had enough of wasting my time with copying files from one hard drive to another.
