Day 4

Two last workshops and let's go to Munich!

On the 4th day, we have done 2 workshops. Firstly, we followed the German one and next, we presented our projects!

I T A L IA N W O R K S H O P

At the Italian workshop we were separated into 2 groups so as not to be too crowded. He showed how a capacitor worked, so we connected a battery to which iron wires were taped to the + and – sides, which we previously stripped to be able to connect crocodile clips and the free ends were inserted on the Breadboard, one in the positive and one in the negative. We then on the Breadboard inserted a capacitor and

resistors then on excel we took measurements every 10 seconds until we reached 1500 V (which was very long) then we disconnected a wire which caused the voltage to drop and then we took new measurements again. After that on Excel, we have used our measurements as a graph and we could well see that at the beginning the curve is increasing then that it decreases.

This curve varies depending on the capacity of the capacitor, rated in uFarad. To see this variation, we have realized this experience with two capacitors, first with a capacity of 1000 uF and the second with a capacity of 2200 uF. We have found that while the capacity has doubled, the time of charge does the same. Moreover, the time of charge and the time of discharge are the same.

FRENCH WORKSHOP

Save lives

During the first part of our workshop, we introduced other students to TI-rovers and added to these small rolling computers different sensors. The goal of our workshop was to imagine a car where greenhouse effect would have made the air inside dangerously hot, and how a smart car could react to such danger.

The first sensor was here to detect an excessive temperature in the car (with temperature sensor). We also added Hall Effect sensors (magnetic sensors) to detect the presence of a magnet (representing a living being present inside the car).

Anemometer

During the second part of our workshop, we presented to the other students an anemometer we had made to measure the speed of the wind. It was a simple prototype that could be easily mounted and unmounted.

We gave them the different pieces and let them try to mount the anemometer up (with a bit of help).

Finally, once the anemometer was mounted, and the wires plugged in, we showed them an incomplete program and let them try to complete it to make everything work.

We had, as usual, lunch in Mensa and met after to leave for Munich! We took the S-Bahn again, but it was shorter this time and arrived 5 min away from the Museum.

We explored the Deustch Museum of science, a huge building where are installed numerous exhibits on very various science-related subjects (physics, pharmaceuticals, astronomy, computers,).

We focused on the electricity part, as it is the main subject of this Erasmus week, and saw a show about electric arcs, very impressive and loud!

There are also very instesting exhibitions about history of science, air transport and sea transport.

This visit was really interesting and we had the first view of Munich, we couldn't wait to come back the next day !

We had dinner directly after the museum, always mixing the nationalities at the tables, sharing and talking in English, we created a real bond with all of these European students!
