Funny facts about the Airbus A380

As I live in Toulouse, I have the chance to see all flight tests from Toulouse Blagnac airport. Indeed this is where Airbus final assembly chain is located. Therefore each aircraft does some flight tests from there and I have the chance to see them. Blagnac was also the place where the first magnificent Concorde took off.

By the way, if you come to Toulouse you can visit the A380 assembly chain. I did it with my school last year and it was awesome, you feel very tiny in there.
For more information, you can go on this link.


Among the aircraft, there is the A350 (I will make an article for this one later) but also the A320neo and the A380 on which I am going to talk this time.

The Airbus A380 is the biggest airliner aircraft on earth. It first flight was in 2005 in Toulouse of course, unfortunately I wasn’t there yet to see it !

There are some specificities with this aircraft that I find intriguing, so I’ll share them with my own pictures.

Unlike the others Airbus aircraft, most of the pieces are not transported with the Beluga A300-600 Supers Transporter ( a beautiful aircraft that I will also talk about don’t worry !). Instead the pieces or carried by boat and then by truck. During the last step they are moving by night and it takes few days. Once I saw where they stopped, here is a picture, it’s a bit blurry sorry :

An other thing is quite interesting in the assembly process. Other Airbus aircraft are fully painted in a hangar in Toulouse. But the A380 is too big to be painted there. So it goes to Hambourg. The rear part also comes from Hambourg and therefore is the only painted part during the first flights. Here is an example with an A380 for British Airways :

My Ideal District in Paris

In this article I’m going to introduce to you the website I created about Paris. Here is the link, for now it is French … sorry. It is meant to find your ideal district in Paris when you want to live in it (hence the title). The result is based on multiples criterias that the user can enter. Every data for the criterias were collected from public database published by the State and the city of Paris thank’s to the OpenData policy. Here are some examples of criterias that you can choose (you can choose up to 10 criterias) :

  • number of velib (the famous self-service bike system of Paris)
  • acces to public transport (Metro and RER)
  • privilege district with bars and restaurant
  • and so on …

The user chooses the priority for every criterias and the website calculates a mark for every district. Here is what the result page looks like, it is an interactive map :

The result page displaying the districts of Paris (in French)

With this website I have 2 goals :

First, it is a great way to provide data to people wanting to live in Paris (the concept can of course be applied to any city). It is very hard to come and live in a city that you barely know, therefore this kind of tool can help you.

Secondly, this website shows what I consider as the true power of OpenData. In my opinion what is really interesting is not that you can do with a set of data but the fact that you can gather a lot of databases. We can now build powerful applications that can show things that were impossible to show before because everything was compartmentalised.

I’ll try to add modifications in the future …

DIY Alarm Clock

For a long time I used my smartphone (which is not that smart by the way) as an alarm clock. But some days ago I decided to create my own alarm clock with Arduino.

I wanted to have an original way of showing the time, I realised that LED matrix were quite cheap, so here is a 3D image of the idea I had :

DIY Alarm Clock project

3D image of my idea – made with Blender

The green lines corresponds to the seconds. The “box” will probably be done in wood (so the picture is not 100% accurate) but I’m sure about the way i’ll place the LEDs.

Here are the features I want to have :

  • simple alarm with a buzzer
  • display time or date
  • control will be done thank’s to a gesture sensor :

    RGB and Gesture Sensor – APDS-9960

    That’s right I want to control it minority report style !

  • Thank’s to the sensor above, I’ll also be avaible to know what is the luminosity in the room and therefore adapt the brightness of the screen.

I’ve already ordered the components, I’ll keep you informed as soon as I start building the project.

High school project : hexapod

I just found old pictures of we project that I had in High School. I thought that it might be interesting to share it with you !

It was in engineering class, there were three of us in my group and we had to make this six-legged thing walk :

hexapod - base

“This” is what we were given at the beginning of the project.

To make it walk, he had to control 12 servo motors (two per leg) with an external card (I can’t remember its name) linked to an Arduino card.

The robot was following the walls of a room. So we needed two ultrasonic range finder in order to avoid and follow them.

Finally, this yellow/ugly thing needed a lot of power to move. So we used a LiPo battery to power it, the same kind of batteries that are used in RC planes.

hexapode - walking old model

First walking model

The electronic part was going well, but our hexapod had difficulties walking because of mechanical reasons. So as our school had a 3d printer (yeah I know we were lucky !), we decided to recreate the robot on Solidworks and to print it.
