Master’s Degree project added

Added the following pages:

  • UniPA BCI Framework project page:
    a Brain-Computer Interface framework which includes many novel features.

Edited parent and other reference pages accordingly.


Brief introduction to the Master’s Degree Thesis:

  • The UniPA BCI Framework is an augmented framework based on the P300 paradigm and allows a user to select individual actions to be performed by a robot or, in the more classic configuration, to spell a sequence of symbols.
  • The framework takes advantage of additional developed modules, which perform the acquisition of eye gaze coordinates and biometric signals.
  • The use of such modules allows to achieve a combined response which does not only take in account the response of a traditional BCI system based on the P300 paradigm, but it also considers useful information, such as the user visual focus and her level of engagement with the system, providing a more robust and effective global response.

Kyoto: A map of places to visit

I thought to share a map of Kyoto points of interest I created some time ago. It mostly contains locations of temples, but it also includes other places I found interesting to visit.

The map is dinamically linked from my google account, so whenever I’ll add more places, they will automatically appear on this post as well. I realise that, for an easier reading of the map, I should change the pin appearance depending on the type of location pinned on the map, but this is something I’ll try to do later, if I find some spare time.

Comments issue and New theme

I have just discovered that there have been some issues in leaving comments which were, apparently, related to the fact that I was still using an outdated theme on the latest WordPress release. I’m not sure how long this problem has been around, my apologies for the trouble.

I’m temporarily using this new theme, and although I don’t particularly like it, it’s still better than a theme that doesn’t let people leave comments at all.
It’s still a bit messy, but it’ll do for now.

More configuration guides for the Raspberry Pi are on my to-do list since quite some time by now. I’ll put them up once I’ll be more free.


Raspberry Pi – VPN Server

Connecting from the University network, I often incur into a very annoying issue, that of blocked ports. I have therefore decided to configure a personal VPN (Virtual Private Network) server where to connect to from university and have true freedom of access to whichever service I would need to use.

Raspberry Pi – Webcam streaming

Now it’s time to make my old Creative Live! Cam Vista IM (VF0260) Webcam work on the RasPi, I also tried a new Logitech C270 HD Webcam and they both work flawlessly out of the box.
I have tried three softwares for the webcam, which I previously tested on my desktop machine running Fedora and I wanted to try them also on the Pi. These are:

  • fswebcam
  • motion
  • mjpeg-streamer

Let’s now have a look at them.

Raspberry Pi – Firmware and Updates

Now that the system is installed on the SD card and the ssh service has been configured properly, we’re going to take care of the system and firmware updates; few words have to be said about the system partitioning scheme.
The Raspbian installation consist of two partitions: the fat16 boot partition, that contains the firmware needed to the Pi to boot, and the ext4 system partition.

Raspberry Pi – SSH and static IP

By the time I received my RasPi, I didn’t have an usb keyboard yet, so my first concern was about how to use it without the keyboard from the very first boot. It wasn’t clear whether the ssh daemon would be active by default or not, and I’ve also got to know that for some distributions, or even among different updates of the same distribution, its default state changed over time.
I found out that in Raspbian, ssh is installed by default but it’s not configured to start up automatically since the first boot.

Raspberry Pi – Preparing the SD card

Download the image:

First step would of course be that to choose and install a linux distribution on the SD card.
I’m personally a RedHat/Fedora user since quite some time but I thought, for the RasPi, to give Debian a go. I decided to install Raspbian “wheezy”, an optimised version of Debian for the Raspberry Pi, and it comes with LXDE as default desktop environment, for those who care about it.
You can download the image from the RaspberryPi Downloads page.

Raspberry Pi has arrived

It’s been almost one month since I received my Raspberry Pi. I actually received two of them, both on day 18th of July, one from Farnell/Element14 via Royal Mail and the other one from RS Components via DHL, which I got for my friend Giuseppe. So far so good, the little RasPi is behaving very well, and I’m testing its stability keeping it up and running, checking cpu and memory usage.
I installed the system on a Sony 8GB SDHC Class 4 card, which I got along with my Sony HX9V camera, bought in Hong Kong a couple of years ago. I’m surprised by the speed of this sd card, achieving 17.4MB/s in read speed and 11.8MB/s in write speed, checked on the RasPi itself with a dd test.
As PSU I’m using my HTC Legend phone charger, rated 5V/1A, which is flawlessly powering it up, by now, for one good week already.
I plan to write some posts as I go developing stuff with it, hopefully and time permitting, so if you are interested, stay tuned : )
