Recently, I have written an article Automatic router reboot device with Arduino where I have presented a simple Arduino–based solution to reset router periodically. Since this is not the best idea to reset it, even if it does not require resetting, I have applied purely software–based solution. As the title says I have used a Python script which runs on Raspberry Pi connected to a local network.
Recently, when I wanted to install IPython notebook server I discovered that for quite some time the project had changed its name to Jupyter. You may recall one of my posts about the IPython where I presented how to install it on Raspberry Pi. Now, I would like to present the Jupyter project to you which comes with some neat new features.
Many articles here and there describe how to use OpenCV on Raspberry Pi. However, most of them are about setting up the environment by hand — meaning compiling OpenCV from sources. There are two main disadvantages to this approach. Firstly, you have to spend some time to compile it. On Raspberry Pi 3 it takes quite some time, and not mentioning the earlier versions of this mini PC. Secondly, maintaining up–to–date version requires additional time. Still, you can go for middle ground — cross–compilation that requires less time but you have to set up the environment properly. Having above in mind I will introduce you to the OpenCV with Python interface installed from pre–compiled packages. If I have your attention keep reading 😉
There are plenty of screens for Raspberry Pi on the market. However, most of them is quite small varying from 3 to 10 inches most.
Some of those screens are dedicated ones some have HDMI interface through which you can connect it to RPi. Well, you can even use analog output to display the content of RPi’s desktop on a TV.
IPython Notebook is a great Matlab-like/Mathematica-like thing. You can write and run scripts written in python by using a web browser only. This post describes how to set up IPython Notebook server.
Raspberry Pi is a small factor fully-featured computer. It can be used for multiple purposes such as a controller.
In most of applications it is necessary to use some kind of communication interface. Raspberry Pi delivers, among others, UART, SPI and I2c. However, UART (serial port) is most commonly used if you just want to send some data between RPi and other devices. While using SPI or I2c in i.e. python script is rather straightforward, using serial port, or making it to work, isn’t so easy as it might seem.
There are situations when we would like to encrypt our Internet traffic. One of those situation is when we use a public computer. Those computers are vulnerable to sniffing. This article will shed some light on this problem.

The Raspberry Pi allows you to connect a camera, either a dedicated one or a Webcam which can be connected via USB port. This post covers how to get an USB Webcam to work.
If your Raspberry Pi is connected to the outside world it is vulnerable. In one of previous post I have described how to make web server out of the Raspberry Pi. There you can find how to make it visible using DDNS.
There are few simple steps which you should follow to secure up your tiny server.
