Video Streaming with Raspberry Pi Camera

In this post we’re going to show you how you can do video streaming with a Raspberry Pi and a Raspberry Pi Camera – how to stream live video into a web page that you can access in any device that has a browser and is connected to the same network the Pi is. This is useful to apply to a home surveillance camera, for example.

Prerequisites:

  • You should already be familiar with the Raspberry Pi board
  • You should have the Raspbian or Raspbian Lite operating system installed in your Raspberry Pi

7-segment Display Modules and the Raspberry Pi

7 segment displays are a well established way of electronically displaying numbers and a small set of letters. They’ve been around for as long as I’ve been playing with electronics but were a pain to wire up given the number of LEDs involved.

Luckily things are a lot easier now that they are available on pre-made modules that uses an SPI interface. This is easy to setup and use on the Raspberry so for about £3 you can add a strip of 8 7 segment digits.

BME280 I2C Temperature and Pressure Sensor

The BME280 device is a digital barometric pressure sensor and is a slightly upgraded version of the BMP180. This is available on a small module which provides access to the sensor via the I2C interface. This allows us to easily connect it to the Raspberry Pi and read the data using Python. The BME280 provides temperature, pressure and humidity.

The BME280 is made by Bosch and the official BME280 datasheet includes all the technical details. Their device can offer both SPI and I2C interfaces so you need to make sure your module provides the interface you prefer.

My module is a small pcb measuring 14x10mm with a 4 pin I2C header. The order of the pins may vary on other modules so keep an eye on the labels so you connect up the correct wires from the Pi.

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!
