Today I had a very interesting seminar about Robolab and the LEGO Robots. I made a program that lets the robot follow a line with only one light sensor.

Finally reached term break. Had Math in the fourth and fifth lesson and did calculating until the last minute. The pupils had no problem with it and did well until the last second.

In every semester on a monday at 5 p.m. you can sign for courses online. And as every semester the server breaks down at 5:01 p.m. Surprise!

Our school got two new LEGO RCX "mindstorm" robo-bricks. I have one at home to test it for use in school. The Robo-brick cannot only be used as robot, that acts in a scenery interactive, it can also be used for taking data and working with them. In my case I attached a temperature sensor and logged the temperature. For this I programmed it so, that it logges the data while it drives a distance. As using the rotation sensor I am able to (later) calculate the temperature with the distance. But that will be another story. The mindstorm project is able to display the data and to generate a website. Have a look at it at this site. And here you can see the robot:

Finished the "Akademielehrgang Elektrotechnik" with a test during a course in St. Kathrein am Offenegg in Styria successfully. The first step to the lectureship for the PTS is done.

It is strange for me and has a "deja vu" experience for me: writing articles for special themes with 20 to 30 pages amount. That means reading, reading, reading and reading other articles, and generate my own thoughts. But two of them came back with: "Well, thats fine and ok". I wrote one more wright this week, so there are only 4 left...

Had a nice advanced education yesterday. 3d pictures in many ways. Stereographs and anaglyphs, autostereographs and optical irritations. We built a stereograph-watcher, took a lot of pictures and produced stereo-pictures, autostereoraphs and anaglyphs. For my anaglyph you need color glasses, left is red, right is blue. Have a look at it:

Today I had my second schoolday and my first lesson. Mathematics. My decision was making a test about 4 years Mathematics in secondary school. Frightened views of the pupils but 50 minutes full concentration. We have 5 classes with 26 - 29 pupils. And on it goes.

At least they started: Summerholidays. Only 65 days remaining until school starts again.

On monday we had a nice trip to Bozen and the Montiggl-lakes. Take the chance and have a look at it: Montiggl.

Today was the last thursday with my pupils from the electro-group. As special event I invited Martin Hotze to tell about internet, networking, security and things like this. Tired kids looking forward the end of the school followed him, some of them used their brain and so they got a glimps of what he does. It was quite interesting, for me too, but after two hours my kids were filled up with info and shut down to silent mode. So this nice afternoon ended, and I hope, Martin will come again next year.
Now have a look at my kids:

Martin telling stories about tracert:

After 6 and a half year of teaching, this year I have the first pupil that uncovered my homepage that I never made public in school: Dominik Lang. His hobby is to offer sound and light equipment for partys. You can have a look at him at dmd-showtechnik.

It took me some days, but now I have finished the grades. Tomorrow I have 2 hours to write them into the catalogues. Then we have a teachers meeting about the grades.

Today I had a fine school-ski-day at Kaltenbach / Zillertal. I had the worst ski-driver. But I had no scruples to show them the black ski-runs. They managed it. The style from 3 of the 8 is called racing-plough. But we had great fun and enjoyed the day together. No bone-brake or other accident occured.

First schoolday after christmas-holidays. Done. So today there are 100 schooldays left until summer-holidays.
