The Raspberry Pi can be connected to the Internet very quickly and easily via the local network. But what if you also need a mobile Internet connection outside your own WLAN? There are GSM modules / Surfsticks (mostly from Huawei), which can be connected via USB. Sometimes are such GSM modules, which support 3G, UMTS […]
Part 6 of the web server installation is about making the server available outside of the local network using a DNS server (such as No-IP, DynDNS).
The Raspberry Pi can be used pretty much for any conceivable application – as well as a radio transmitter. Frequencies from 1Mhz to 250Mhz can be used, including the usual radio frequencies between 88 and 108Mhz. Depending on the position and antenna, the signal can be transmitted up to 100 meters. In this tutorial, I […]
With the release of the Raspberry Pi 2, Microsoft had announced they will provide a version of Windows 10 for the Pi. This has happened now. According to Microsoft, this is only possible with the PC version of Win 10, but it also works on Windows 8.1, as I show in this tutorial. Windows 10 […]
Anyone who has dealt with image processing in relation to the Raspberry Pi will sooner or later come across the OpenCV library. It provides many very useful features such as face recognition, the creation of depth maps (stereo vision, optical flow), text recognition or even for machine learning. In addition, OpenCV (Open Source Computer Vision) […]
Siri, Amazon Echo and “S Voice” are all voice recognition programs designed to make life easier. Even a Raspberry Pi voice control can be easily built by yourself. Because such a speech recognition is of course very beneficial for home automation. In this tutorial, I’ll show you how to digitize speech through a microphone, convert […]
This tutorial demonstrates how to automatically run scripts for text commands via Telegram after the installation on the Raspberry was covered in the previous tutorial. This allows you to, for example, easily query the status of your Pi’s on the go or simply perform actions remotely via your messenger.
Some of you know about the safer WhatsApp Alternative – Telegram. If you also want to send and receive Messages, Pictures and Videos on your Pi, this is the place for you. All you need is an additional Sim Card to receive the SMS. In a later tutorial, we will use receiving Messages to perform […]
Again and again, it happens that you install Programs, but do not start them automatically when booting. In order to use the Raspberry Pi autostart, all you need to do is to store the information in the /etc/rc.local file in the Linux system. This is, for example, the case with DNS service noip2. In the […]
The Raspberry Pi is ideal for monitoring, so local live streams can be set up (via Android, too). Also, a Raspberry Pi Youtube Live Streaming is possible, e.g., for somebody who wants to watch his plants grow or wants to share other projects live. In addition, it is possible to make the stream publicly or […]
MQTT is a protocol that specifically sends data from devices of the Internet of Things and is supported by most microcontrollers and systems. To use Raspberry Pi MQTT communication, not much is needed, which is why this type of transmission is very interesting. In addition, it is really easy to use. In this tutorial, we […]
