Small internet radio stations seem to be very popular at the moment. They are being installed more often in the bathroom, kitchen or living room because on the one hand they have more programs than the old-fashioned radios and on the other hand the sound quality is getting better and better. But what these Internet […]
In addition to some wireless connections such as 433Mhz, infrared and NFC, Bluetooth is probably the most common and popular mode of data transmission between smartphones, which is why the Raspberry Pi Bluetooth data transfer is interesting. Meanwhile, pretty much all devices support Bluetooth and can not only be paired with it but of course, […]
Frequently, a lot of data is generated in projects that run around the clock. One way to store them permanently is to store the data in a local database. However, there are also some reasons that speak against it. In order to keep the measured data (for example, from a weather station) available in the […]
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 […]
