A beautiful and dynamic experience that I hope will be repeated again.
Congratulations to the organizers and participants of this conference.
Their contributions to Free Software was invaluable.

On 21/12/11 at TheHackerspace we made 3 presentations on game developing by using open hardware and free software. Specifically, the presentations were: a) competitive multiplayer game for reinforcing visual skills and reflexes implemented with Arduino, b) engine for moving various sprites in two-dimensional games implemented with Python and Pygame, c) various games with Arduino and Gameduino.

TheHackerspace (Thessaloniki’s Hackerspace) is here!

We announce that at 7.00 pm on Thursday 30/6 we organize a kick-off event for the presentation of TheHackerspace at the Art Cafe “Kokini Klosti Demeni” which is the permanent meeting place at 32 Nicosia Street, Kalamaria, Thessaloniki. Come to get to know us, to see you and share ideas!

The TheHackerspace is an open laboratory for research, collaboration, creativity and learning. But above all, it is a vibrant community of people with ideas and concepts stemming from the philosophy of Free Software / Open Hardware. The idea for the project was started a few months ago by people who love Hacking, both software and hardware, and soon was put into practice with passion and desire to contribute to the community.

Our moto is “Love to hack embedded & operating systems!“.

Happy Hacking,

Dear Readers and Friends of Free Software,

On 5/30/11 (Sunday) there was the fifth seminar, thus completing the circle of free seminars on the ARDUINO open source electronic platform. Specifically, at the fifth seminar I presented my thesis whose subject is the following:

Network implementation of wireless radio communication between two embedded nodes (identification node ​​and control node) for the remote control of devices via digital identification and recognition of physical objects using the Arduino platform.

I feel I must express a very big thank you to the Association of Greek Users and Friends of FS / OSS, especially the living people behind it who are perfectly respectable and cooperative personalities, open minded and with a progressive dynamic potential, giving me the opportunity through this cycle of free workshops to distribute freely my knowledge and my experience on the world of Embedded Systems.

Sincerely,

Efstathios Chatzikyriakidis

The Association of Greek Users and Friends of Free Software / Open Source Software invites you to the new presentation in the new round of free courses and presentations organized with a view to deepening the knowledge and alternative use and exploitation of FS / OSS:

Fifth Seminar on the Open Source Platform ARDUINO about:

Network implementation of wireless radio communication between two embedded nodes (identification and control node) for the remote control of devices via digital identification and recognition of physical objects using the Arduino platform.

Important Notice: It is necessary to attend this seminar for obtaining certifications by those who attended the Arduino seminars organized by the GreekLUG in the year 2010 – 2011.

The presentation will be made by the Informatics Scientist and Communications Engineer as well as Arduino hacker, Efstathios Chatzikyriakidis on what is the first thesis based on the Arduino in Greece.

The event will take place at 17:00 on Sunday, May 29, 2011 in the Computer Laboratory of the Department of Economics, University of Macedonia.

The Free Software / Open Source Software Association (FS / OSSA) recently organized a conference entitled “Open Source: Opportunity Development” in various cities. Also, last Sunday (22/05/11), I had the opportunity to attend the one-day workshop held at the University of Macedonia in Thessaloniki.

Within the framework of the course “Computer Networks III – Theory” (Department of Informatics and Communications, T.E.I. of Central Macedonia) we were asked to write a presentation related to the content of the course. The topic of my presentation was Genetic Routing.

On Sunday 19th December 2010, there was the fourth seminar on the ARDUINO open source electronic platform in the same place where the previous one was also held.

In the presentation of the fourth seminar, we studied cases of use of wireless communication with ARDUINO. Initially, we discussed the basics and the theoretical aspects of wireless communication, the advantages and disadvantages in radio and infrared communication.
