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.

Adding an external power supply to a cheap USB hub

Hi again! In this post I'm going to show you how to add an external power supply to a cheap USB hub. :)

I've been running some experiments with two Logitech Quickcam for Notebooks Pro and the Raspberry Pi and unfortunately I haven't been getting any good results. I can't get many fps and some of the captured frames contain corrupted data but I think I may have found out the reason for that. After some reading I verified that the USB ports of the Raspberry Pi can only source 100mA to a device and maybe the cameras are consuming more than that. To bypass that problem I went out to buy a USB hub with external power supply.

First Impressions on the Raspberry Pi

Hi again! A few days ago I made a post about the Raspberry Pi board that I recently got in the mail. I only made a short description of the board since I hadn't test it at the time. I still haven't much to say but I have finally tested it and I'll share my first impressions of the board.

Raspberry Pi has arrived!

Hi! I just want to share with all of you what I just got in the mail yesterday! :D

The world famous Raspberry Pi (model B) has arrived! :) I thought that I would have to wait 1 or 2 months from the order date to get one but happily it only took 2 or 3 days! RS was extremely fast shipping it :)

For the few of you who still haven't heard about the Raspberry Pi, it is a full computer with the size of a credit card (85.60mm x 53.98mm x 17mm)! It's just one of those incredible things that will change the world as we know it :).

Now you may be thinking "Wow, that must cost a lot of money!..." but the size of the board isn't the only small thing about it! It only cost me 40€ with shipping included (from UK to Portugal) :) . Here are the full specs:
