What is PoE? PoE, or Power over Ethernet, descibes several standards for passing electric power along with data over twisted pair Ethernet. This way power can be delivered to devices such as Acces Point, Camera’s, Phones,… From the several common techniques for transmitting power over Ethernet cabling, only three are standardized by IEEE in the IEEE 802.3 standard. Requirements In this episode we’ll adapt our cluster to use the PoE switch (or injectors). we’ll do this to reduce the required …

This tutorial is a basic view into the ansible package. Ansible is to big to incorporate in a single tutorial so we’ll only touch the outer layers. In this tutorial we’ll use one of the nodes, later on known as the Master node, to control the other nodes in out network. Note that you don’t need a cluster to use ansible. Requirements Any raspberry Pi Cluster with 2 or more nodes.Or multiple Linux servers/machines. Setting up the software Before we …
You got a nice project running when suddenly krrsttrsrs, your SD card fails. Disaster has struck. Now you need to begin all over again, and s**t you can’t remember exactly how you’ve done things. Now how could we have prevented this from happening? SD cards fail due to constant writing to it, so if its possible you could make it read only.But that is out of scope for this tutorial and will be covered in a future one.What we are …
If you have a lot of spare Pi’s around, like I do, you’ll probably want to do something with it.So after a few searches for a new project i found that it was possible to use them in a cluster. So what is a cluster? In this case a cluster is a group of Raspberry Pi Computers all working on a part of the task you want to complete. You can start your cluster with as little as two Pi’s, …
What is Node Red? –Node red is a Open Source flow based tool and IOT platform and Dashboard developed by IBM and written in Node.js. Node-red lets you easily applications by joining together black box functions (nodes) using a web interface and requires very little, if any, programming knowledge. Because of its flexibility and ease of use node-red is ideally suited for building IOT and Home control dashboards and automations. Here is a the official introductory video from the node-red …
When you are in a cooperate building, or just at home where you have to connect to a proxy server to be able to connect to the internet or a separate network.In this quick tutorial we’ll take a look on where you need to put these demn settings so you can update your Pi and access the internet behind your proxy server. Know your Proxy Before we can continue you need some basic info about your proxy. Without these you …
What is NTP?NTP or Network Time Protocol is, as the name implies, a protocol that is used to synchronize time over a network. All system clocks in a network use the same time reference. When using the term NTP, we are referring to both the protocol and the programs running on the computer(s)/server(s). In this tutorial we’ll setup a NTP server and configure a Client to use this server.The method described here can be used on any Debian system. NTP …
You can check the status of your Pi using SSH and typing some commands, of even run a shell script to simplify it. This could be a big chalange when you don’t have a big knowledge of Linux and Raspberry Pi. But it wouldn’t be Linux if there wasn’t an other way to do it. RPi monitor gives you a basic view of the information about your RPI’s CPU core temp, CPU load, Uptime, … For the more advanced users …
In this mini series we’ll take a look at the Pi Desktop from element 14 (not compatible with the RPi4!)In this Episode we’ll take a look at the hardware itself and how to ‘built’ it.Lets get started. Requirements Pi Desktop Raspberry Pi 3B (+) Intro The Pi Desktop is a case for the raspberry pi version B or B+ (including the 2B, 3B and 3B+).Due to hardware changes it is not possible to use this in combination with the PI4. …
