Raspberry Pi 3G using a Huawei E303 modem and DynDNS (English)

Long-time readers of this website might recognize this article. It was the first article, I published on nerdhut. As of today, this is still one of the most popular articles on the page and because of that, I decided to shorten it a bit and translate it to English.

However, the original German version remains online here!

Introduction

Due to my work on a remote-controlled unmanned ground vehicle, I searched for a way to control it anywhere in the world. Because I wanted it to have a high range and reliability, I decided to communicate with it over the internet, which should be available almost anywhere on the planet.

Use SCP for remote file transfers on Mac/Linux/Windows

This will be short article with a quick hint. I wanted to write it, because I often get asked how to easily transfer files from a machine to another. Of course you could just upload a file to dropbox and download it on the other machine, but for this method you can transfer files to a headless system easily and without having to physically access the remote computer, which is quite handy if the remote computer is somewhere else than you are.

Sometimes you need to transfer files from one computer to another. The simples way of sending files between computers in your home network is using SCP (secure copy). For those of you, who use a UNIX based system, SCP is already built into your system. I often have to transfer files from my macintosh computer to a Raspberry Pi or BeagleBone, so using SCP comes in very handy for me. This page is intended to be a quick and very short reference for secure copy. For more details, visit the scp man page.

If you are using windows, there is an alternative for you below!

BeagleBone Black programmable realtime unit (PRU) Hello World – Part 1

Introduction

This part covers the device tree overlay for our little Hello-World Example. I will not cover linux device trees here or why they are useful, because other articles in the interweb already contain great articles about this topic. I will give you some links at the end of this page. Continue reading BeagleBone Black programmable realtime unit (PRU) Hello World – Part 1

Raspberry Pi 3G mit Huawei E303 und DynDNS (Deutsch, Teil 2)

Einleitung

Fortsetzung von Teil 1!
In diesem Teil der Miniserie geht es nur darum, einen DynDNS Dienst auf dem Raspberry Pi einzurichten. Das ist, je nachdem welchen Dienst ihr gewählt habt, ein recht trivialer Vorgang. Ich verwende für meine Zwecke DuckDNS, ganz einfach aus dem Grund, weil das Einrichten schnell von der Hand geht und ich Enten mag.

Geschichte

Für meine Arbeit an der ferngesteuerten Drohne habe ich bereits vor langer Zeit angefangen, eine einfache Möglichkeit zu suchen, diese praktisch weltweit ansprechen und steuern zu können. Da die Reichweite und Zuverlässigkeit der Kommunikation bei dem Projekt an oberster Stelle stehen, kam mir schnell die Idee, die Kommunikation über das mobile Internet laufen zu lassen. Dieses ist doch grundsätzlich überall dort verfügbar, wo Menschen Handys benutzen. Also (fast) weltweit. Continue reading Raspberry Pi 3G mit Huawei E303 und DynDNS (Deutsch, Teil 1)
