day 3 of embedded world

OSADL

The final day of the exhibition “embedded world” was a bit less exhausting. We spend some time speaking to the people of the stand linux meets industry. This organisation is supporting big companies running and developing open source software as well as spreading the open source thinking.

The rest of my day was quite relaxed… we walked around a bit and talked to several companies as well as some people who were interested in the project leobots.

All in all the exhibition was a big success for the team as well as for me. We all got some great impressions what the embedded industry is like at the moment.

Today I spoke to some companies that I might work for in saxony. There are quite a lot of them, that I did not know before or I did not know that they also develop hardware themselves. This is why today was a great success for me. But on the other hand the days get more and more exhausting – fortunately the exhibition ends one hour earlier tomorrow. I’m very tired right now…

After the official end of the visitor opening times there were some parties at the microsoft and ebv stand among others. Thanks to them for providing some food and drinks for us while playing music! Also thanks to the “open source meets industry” guys who are always worth talking to! Especially I was enjoying to meet Benedikt Sauter (http://embedded-projects.net/) finally after following his work since several years now.

One thing I want to show you finally is an automatic solver for the rubik cube. Basically they built a lego mindstorms robot that handles all the turning and used a smartphone to capture the recent state of the cube. These two elements are combined by a pc that solves the game and controlls the robot while capturing the images form the smartphone:

Today was the start of the exhibition embedded world. I’ve met a lot of interesting people and got some offers for the practical semester starting this september. I will visit some other halls tomorrow.

Because I’m at the exhibition with the leobots team, I was also going around the halls with the robot and talking to some of the sponsors and companies who might become sponsors.

Today I travelled to Nuremberg with the other participants of our exhibition stand. We arrived really early about 4pm and equipped our stand for the tomorrow starting show.

Afterwards I went to my hostel room. I took a bed at A&O Hostel in the city center of nuremberg. It is next to the main station. As far as I can judge until now it is great.

After unpacking my stuff into the tiny locker in the room, I went to buy some food. On the way to the supermarket I came along a shop that was selling used stuff. I noticed a tripod in the shop windows. They sold a really nice looking one for only 29€, so it had to buy it at this bargain 😉 Just a picture with my crappy mobile phone cam:

When I came back to the Hostel I tried to connect to the internet. Seems that simyo delays the booking of the umts flatrates by some hours, so that I started whatching a movie. Some minutes later a roommate arrived – he came directly from india. He is going to visit the same exhibition, so we talked a while until we decided to go to a bar and have a beer and talk about the different cultures…

Some random updates

Some of you might know it already: I stop to participate at the students project Leobots at my university. There were some disagreements in the team over the last weeks that led to my decision to leave the team as of now. I just finish the documentation of my work as far as I got and support the team at the trade fair “embedded world” next week.

As I still like to play around with robotics I bought a small rc car, a wifi-router and some electronics. I hope to get it somehow self driving and self navigating in unknown terrain.

I think my other new toy, the 3d printer will be a good help for my modifications… at least for adding backets for the distance sensor that is scanning the sourrounding of the car it will be superb to have a costum made part that really fits my needs 😉

Greek Letters in Inkscape

I am currently writing a report for a university project. In this report I’d like to illustrate the eurobot playing field, because I work on the absolute positioning system for the robot of the team leobots. To visualize what angle definitions I used I wanted to label them in an vector image which I already created in Inkscape.

First I tried copying the greek letters from wikipedia… for alpha and beta it looked quite nice, but not for gamma. So I searched the web for it and found that (german) discussion about it: http://www.inkscape-forum.de/index.php?p=/discussion/1359/griechische-buchstaben/p1.

In short: you can do:

  1. create a text element
  2. switch the font to any font that supports unicode (Times New Roman does)
  3. CTRL + U
  4. enter the unicode (03B1 for alpha, 03B2 for beta, 03B3 for gamma)
  5. press enter
This is how my result now looks:
