A LCD display my RPi and RPi-Monitor

I saw on the internet that it is possible to use a LCD to display information from the Raspberry Pi. RPi-Monitor is gathering a lot of information and it could be interesting to have such an information available without a computer. So I decided to purchase a PCD8544 from dx.com.

      RPi-Monitor: Build a multi-sites SSL certificate to improve user experience

      This post comes in addition to my previous post: RPi-Monitor: Security and authentication with a reverse proxy.
      You may notice that your browser do not trust the certificate we generate consider it as insecure. In this post we will see how to create our own certificate and certificate authority. We will also see own to configure our browser to trust our certificate authority and consider the associated certificates as secure.


      Thanks to this actions, we will then move from https :-( to https :-) and remove the security warning.

      Note: A new version of RPi-Monitor is available: Version 1.1
      All the details about the latest version of Rpi-Monitor are in RPi-Monitor overview
