DIY: Black Rolls/Trigger Point-like foam rollers for myofascial release

Black RollsFinished DIY version

I am a big fan of using foam rollers for myofascial release, especially after workout.

There are a lot of foam roller products for myofascial trigger point treatment out there, but I am too cheap to buy a piece of recycled plastic pressed into a cylindrical form for 20 EUR or higher. This is one of the easiest DIY projects possible, so make your own! Continue reading

Samsung Galaxy S3 repair – Glass screen/digitizer replacement and why it is not recommended

Glass screen replacedA friend asked me to repair her friends Samsung Galaxy S3 mobile phone, that had a broken glass screen/digitizer, so I had a closer look at it. The process of replacing the glass screen/digitizer on a Samsung Galaxy S3 is straight forward and not many tools are needed. However, what you really need is patience… a lot of it.

This post shows how it is done and why I still would not recommend it anyway.

DIY: “barefoot”/natural running shoes

Finished sole

At the end of last year I went to a sports and health fair, where I wanted to have a closer look at the available natural running shoes, especially the ones from Vibram (FiveFingers) and Leguano. Both type of shoes were comfortable and seemed to be of good quality. However, with an above the 70 EUR price range, they are quite expensive for a shoe that aims to be like no shoe at all. In fact, they are more like a pair of high quality socks with a special thin rubber layer glued to the sole (whereas the Vibram FiveFingers also seem to have some supportive structure integrated, which is kind of a contradiction to the barefoot philosophy). Making a custom fitted version should not be that hard, so I decided to make my own.

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.)

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.

Cheap Home Server: Introducing the Thin-Server

A little while ago I finally made the decision that I would like to have a server at home and I was at first fascinated by the SheevaPlug, but many people complained that the powersupply of it would die within weeks, so I needed an alternative but I still didn’t want to use a regular computer because of several disadvantages;

  • It would be to loud
  • It would consume too much energy
  • It would be overkill for my purposes
  • The hardware is relatively expensive

But when I had a look on Ebay, I stumbled upon a Thin-Client, which is essentially a small, low power computer, that is used in companies as something like a next-generation terminal. Since it did only cost 50€ I thought I would just give it a try.
