Weather Balloon Project Meeting

There are some people of the Hackerspace Ulm that are interested in sending a weather balloon with some measuring and communication instruments. On Thursday 2nd of October we will get together and start to plan the project. New people are more than welcome to join us. We will start the discussion around 9 pm.

The next meeting will be in one week on Thursday 9th of October at 9pm. If you can´t come for the first meeting you are welcome to the second one.

Thursday

It’s summer holiday season and we had a visitor from Hackerspace Bielefeld. He told us about the history and the ongoing projects of the hackerspace. We gave a tour in our hackerspace and we visited Radio freeFM as well. We had very interesting discussions and we got very good project ideas as well.

There was a short introduction into through hole component and SMD (surface mounted devices) soldering. Later in the spring there is planned to be a course on PCB (printed circuit board)-design and manufacturing.

 

Diesen Donnerstag: Vereinsgründung

Diesen Donnerstag (3. April) werden wir endlich die Vereinsgründung angehen. Besucher sind natürlich weiterhin willkommen, aber bitte habt Verständnis wenn wir ab 20:00 mit Organisatorischem Kram beschäftigt sind

Organisational meeting this thursday (April 3rd)

This week we will begin with the first official steps towards a hackerspace-association for ulm. Feel free to visit the Freiraum as always. However, please understand that our members will mostly be busy with organising things.

Freiraum offen am Wahlsonntag

Anlässlich der Bundestagswahl 2013 wird der Freiraum am Sonntag (22.September) vorraussichtlich von 12-20 Uhr geöffnet sein.

Wir werden wählen (oder auch nicht), Statistiken erstellen (oder es zumindest versuchen), das Bundesradio Wahlstudio schauen (oder was sonst gewünscht wird) oder den Wahltag sonstwie hackertypisch begehen.

Besucher sind wie immer herzlich eingeladen.

Freiraum hitzefrei

Auch Geeks machen Urlaub und deshalb wird der Freiraum heute (5. September) vermutlich nicht geöffnet sein (es sei denn von den Mitgliedern kommt doch jemand).

(man beachte das Wortspiel: frei-raum–hitze-frei ;))

Last Thursdays activities: Antenna building, project presentations

Every Thursday there is a Meeting day in the Hackerspace Ulm (also known as the Freiraum). New people are always welcome to join us.

Last Thursday (22nd of August 2013) there were lots of things happening in the Hackerspace. We build some ham radio (Funkamateur) antennas and then we measured them using Vector Network Analyzer (VNA). The antennas were surprisingly good although we did them quickly using some cheap basic material. The nature of laws don’t respect the price of building materials ;)

We also found out that the VNA is a really good instrument for testing different kind of antenna types that people themselves invent. Its really easy and quick just to make an antenna and them measure it. Then you can make some changes and measure again. This could be called evolutionary antenna building.

There were also other things happening. Some people presented their projects ideas and other people were giving comments and new ideas to them. This way the projects can get lots of input and some problems can be solved. It’s also an opportunity to get other people interested of the project and get them on board. To make something together makes it more fun.

Measuring a discone antenna with vector network analyzer.  Discone antennas are wideband antennas (in this case about 80 – 500 MHz).
