Docker on RaspberryPi

Installing Docker on a RaspberryPi might seems overkill, but it actually works pretty well, even if installing the tools can be a little messier if you don't know how to do it and you start searching the Internet for clues. After being intimidated by the many alternatives given to you to overcome the lack of …

nRF24 walk through – Introduction

The Nordic nRF24 is a family of silicon integrated radio transceivers operating in the 2.4GHz band, the most popular one being the nRF24L01. This is the core element of some extremely cheap module boards available in online stores like eBay, Aliexpress and Banggood. These boards do not provide WiFi (801.11) or Bluetooth connectivity (both in …

nRF24 walk through – Building the sensors

It's now time to physically build the sensor devices part of the nRF24 sensor network we are planning to build, so move to your electronics bench and pick some breadboards! From an electronics point of view each sensor node consists of: 1 Arduino (any low-end model will do, I will be using two nano and one pro …

nRF24 walk through – Sensors’ firmware

Let's move to the 3rd part of the nRF24 walk through series before the excitement cools off, shall we? Now that I have three boards wired and I'm certain only my code can break things up, it is time to create the sensors' firmware. It should be quite simple: all we need to do is getting the …

I took the opportunity to perform …

nRF24 on Raspberry Pi

NOTE This post has been quite successful, so I decided to publish a complete series on nRF24 transceivers. I'm working on a home automation project and I'm planning to use my Raspberry Pi as central node of a network of cheap nRF24 nodes. First thing is to get the necessary compilation tools, something quite easy to …

Raspberry PI First Hands-On

I just received my Pi and as soon as I started using it I found a few issues: nothing exceptional, but if you have got the habit to have almost everything working out of the box on your Linux boxes (due to good Linux distributions) you might have lost a little of confidence with this …
