Hi! I have some good news about this blog! :) Probably you've noticed the little Portuguese flags at the beginning and at the end of each post. Well, they're direct links for The Bit Bang Theory blog's Portuguese twin brother: Teoria do Bit Bang :) .
When I started this blog I decided to write in english for several reasons:
  1. We no longer live in our street, village, city, country, etc. We live in a global world. With the evolution of Internet we now have access to things made on the other side of the world in a matter fo seconds;
  2. English is the universal language;
  3. Portugal is a really small country and I thought that the number of readers would be rather small;
  4. Most of the Portuguese people that are interested in the things written in this blog understand English pretty well.
However, after one year and a few months of blogging, after creating a Hackerspace with some friends, after knowing some more people with the same interests and after seeing that Portuguese people are the #2 readers of this blog (being people from the United States of America the #1) I decided to create a twin brother for this blog and embrace some new objectives:
  1. Provide technical information regarding robotics, electronics, computer science, etc. to Portuguese readers;
  2. Show some people that technical stuff doesn't happen only in universities and big companies, it can happen at home too, and it can happen here, in Portugal;
  3. Motivate others with the same interests to get into electronics, robotics, mechatronics, computer science, etc..
So, if you're Portuguese, from now on you can read this blog in your mother language :) If you're not, you can still read it in English. I hope this to be a good decision and a big step forward for this blog :) . 

Take care!

Turning the Raspberry Pi into a Wireless Access Point

Hi! Following my latest posts on how to get started with the Raspberry Pi "headless mode" and Using Bluetooth with the Raspberry Pi now I'll show how to turn the Raspberry Pi into a Wireless Access Point. Most of this post follows what is described here but I added a few more steps. Moreover, I ran into some troubles and had to do some troubleshooting. I used a D-Link DWA-140 Rangebooster N Adapter which contains a Ralink RT2870 chipset.

 The process looks a little long but it can be done in under 10 minutes :) . Every time you need to edit or create some file (for example /etc/udhcpd.conf) among this process you can use "sudo nano /etc/udhcpd.conf".

Hi there!
Following my previous post on how to get started with the Raspberry Pi "headless mode" I'll now show you how to install the Bluetooth tools.
On the project that I'm working on right now I'll be using Bluetooth with the Raspberry Pi so that later I can connect to several devices via Bluetooth. For this purpose I have ordered some USB Bluetooth dongles from ebay and some HC-05 Bluetooth modules, also from ebay.

The first thing to do is type "lsusb" in the terminal to see if your USB Bluetooth dongle is being recognized. As an example, the ones I ordered from ebay show up as:
Bus 001 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

Headless start with the Raspberry Pi

Hi! Some time ago I made two posts about the the Raspberry Pi (Raspberry Pi has Arrived and First Impressions on the Raspberry Pi) and unfortunately since then it has been closed inside its box. I really wanted to do something with it but other projects always got in the way. Finally I'm doing a project where I'll use the Raspberry Pi and I hope to make some posts about Raspberry Pi stuff while I work on it. To begin I'll show you how to start playing with your Raspberry Pi without having to connect it to an external HDMI monitor or screen with RCA connector and using Ubuntu on your computer.

The first thing to do is get yourself a 4GB (or greater) class 4 SD card. Branded cards are usually better and more trustful. If you have one, then its time to prepare the card to be used in the Raspberry Pi.

How to install Chrome on Ubuntu 12.04

Hi! Today I'm just going to provide a very quick and easy tutorial on how to install Google Chrome browser in Ubuntu 12.04 Precise Pangolin.

It's really, really easy. First go to this link and download the .deb package for you CPU (32-bit or 64-bit). Then open the terminal and get into your Downloads folder and enter the following command:
sudo dpkg -i google-chrome-stable_current*.deb
If you get some error regarding unmet dependencies you can fix them by entering:
sudo apt-get install -f
And that's it! Google Chrome will be installed in your system! :)
