Fab academy 2009-2010 Graduates

First year of Fab Academy was a success and we congratulate all the graduates.

The ceremony was held in Amsterdam during Fab6 and unfortunately not all the graduates were able to attend the ceremony.

I was asked to prepare a speech on why i choose to be a Fab Academy student this year and one great lesson she learned from her year in the Academy.

LCD CIRCUIT

SOCCER STADIUM

INTRODUCTION

We as the fab academy students from South Africa we decided to collaborate on the projects and build a soccer stadium as the world cup is coming to South Africa in the next few weeks and we all have the fever for soccer.

When we were thinking on what to do for the final project we asked ourselves the following questions

1. Its 2010 what can we do?
2. The world cup is coming to South Africa and what can we do in the fablab that can show that we also support the world cup?
3. What is that that we can do that will be a combination of what we have learnt throughout the semester of fab academy?
4. Print T- Shirts, ok may build a stadium with Perspex and add some electronics on it?

And we finally got our answer a soccer stadium.

THE IDEAL PICTURE

Soccer-City

We will build the structure with Perspex which will be a combination of computer-aided design, manufacturing, and modeling, computer-controlled cutting, molding and casting , and add the light intensity controlled lights which will switch on when it is dark and we hope that we will succeed on the sound as we want to add the vuvusela sound as we South African a soccer match without a vuvusela is not a match which will fall under digital fabrication principles and practices, electronic design and production, computer controlled machining, embedded programming, sensors, actuators and displays.
