Build Your very own DNS server with a Raspberry Pi

In order for computers to communicate with each other over the internet, all participants in the network have a unique address: Through IP addresses, clients know exactly which servers they should address. But no user can be expected to memorize the numerical sequence of the address, so instead, domain names are used. For this, there’s a domain name system (DNS): It converts numbers into domains and vice versa. To do this, clients first have to query one or more DNS servers before they get the correct address. This can cost valuable time. Therefore, it can be useful to speed up the internet connection by setting up a dedicated DNS server. A Raspberry Pi, the small but many-sided computer, provides a good base for this. We explain to you here how DNS functions and how you can set up your own home DNS server.

Connect Bluetooth Headset Or Speaker

In this post, I’ll share with you the final solution that lets you connect your Bluetooth headset or speaker to Raspberry Pi 3.
You’ll be able to use both output speaker and input microphone.

By the way, thanks to the people who kept me updated in the comments, it was a long journey together (:

Firstly, let me sum up the root causes of this long time problem:

  1. Drop-out of ALSA support in Bluez v5 (replaced by PulseAudio).
  2. Unavailability of correct PulseAudio version for Raspbian Jessie.
  3. Incorrect audio rooting SCO-HCI for the Bluetooth chip BCM43438.

I solved the issues 1 and 2, but I couldn’t find a good solution for 3. For issues 1 and 2, I found how to install manually PulseAudio, with code sources, or using Debian backports. For issue 3, I used a BT-USB dongle that bypassed the internal Bluetooth chip and let me use A2DP and HSP profiles.

Install WordPress on a Raspberry Pi using Nginx

Today we will install WordPress, the most popular CMS in the world (not to mention the fact that it runs Raspbian France) and see how to install it on the Raspberry Pi.

The Raspberry / WordPress compatibility exists since the beginning, nevertheless, the performances on the first Raspberry Pi were not incredible! Today, with the Raspberry pi 3 and the Raspberry Pi 2, it’s ancient history! Their processors and the RAM mounted at 1GB offers us the possibility to run more than correct way a wordpress site under Raspbian!

Interfacing the Neo-6M GPS Module & Raspberry Pi with LCD Readout

One of the coolest embedded platforms like the Raspberry Pi has given makers and DIYers the ability to get location data easily using GPS module and thus build things that rely on location. With the amount of power packed by the Raspberry Pi, it certainly will be quite awesome to build GPS based projects with the same cheap GPS modules and that is the focus of this post. Today in this project we will Interface GPS module with Raspberry Pi 3.

The goal of this project is to collect location data (longitude and latitude) via UART from a GPS module and display them display on a 16×2 LCD, so if you are not familiar with the way the 16×2 LCD works with the Raspberry Pi, this is another great opportunity to learn.Read More

Measuring Rotation and acceleration with the Raspberry Pi

Acceleration and rotation sensors are most known from smartphones. The rotation of the device can be detected and can be addressed directly.

With the Raspberry Pi and a Gyroscope / Accelerator sensor it is possible to measure the rotation as well as the acceleration of the 3 axes.
In this tutorial use the MPU 6050 Gyroscope / Accelerator sensor interferfaced to a Raspberry Pi, and reads the values using I2C.

Components:

For this tutorial I have used the following components:

  • Raspberry Pi
  • MPU 6050 sensor module
  • Jumper Cables
