The Raspberry Pi just turned 10 years old. It all started in 2012 with the announcement of an inexpensive, power-saving computer on a single board running Linux. What followed was a sensational success, with about 40 million units sold and many thousands of projects and applications developed, from video/audio to home applications to surveillance systems. Elektor was one of the first magazines to cover Raspberry Pi, with the usual mix of theory and practice. Below I highlight 10 memorable RPi-related articles from Elektor's comprehensive archive.

Notable Raspberry Pi Articles in Elektor

Raspberry Pi: One Year Later, One Million Sold
In 2013, Clemens Valens from the Elektor lab met Peter Lomas (the “Raspberry Pi hardware guy” at that time) at the Embedded World 2013 trade show in Nuremberg, Germany. Valens found it to be an excellent opportunity to catch up with the Raspberry Pi Foundation. Read the Article

Raspberry Pi Voltmeter with Color Display
It is simple and it works: just a few additional components are needed to turn a Raspberry Pi into a DC voltmeter capable of reading up to 5 V and displaying the results in color on a monitor. The entire display area can be used, which makes the project an ideal basis for demonstrations (for example, in schools). Read the Article
Raspberry Pi Buffer Board
If you experiment with the Raspberry Pi on a regular basis and you connect a variety of external hardware to the GPIO port via the header, you might cause some damage. A voltage that’s too high, or an electrostatic discharge, can blow up the port and you can say goodbye to your cherished credit card sized computer. You can use the Buffer Board to prevent this!

Raspberry Pi Buffer Board
RPi Buffer Board: never blow up the I/O again.
DIY I2C for Raspberry Pi
Check out this short article to learn about building your own I2C slave device using a PIC microcontroller and how to control it with the RPi. This approach combines the power of a microcontroller with the flexibility of the RPi. Read the Article
Door Spy using Raspberry Pi
An unexpected visitor can be a welcome surprise; but at other times, you might want to ignore a less desirable guest on your doorstep. With this project you can, in principle, see who rings your doorbell, have a conversation with that visitor, and even remotely open the door provided you have your smartphone on you. Read the Article
Audio DAC for Raspberry Pi
Small single-board computers like the RPi are ideal for use as small stand-alone network audio players. With Volumio and other specialized Linux distributions, putting together an audio player is remarkably easy. And as Elektor Audio expert Ton Giesberts shows in this article, you can also use this approach to build a high-end audio player. Read the Article
Swiss Pi
One thing that has certainly contributed to the popularity of the RPi is that the 40-pin GPIO connector makes it very easy to extend the basic board with custom modules. Peter S’heeren and Ilse Joostens from Elektor Partner company Axiris felt challenged to develop a multi-purpose tool. Read the Article

Java on the Raspberry Pi
While the Java programming language has been around for a long time, it is still very suitable for developing code for modern computing platforms such as the RPi. To demonstrate its capabilities, the first part of this series provides some background on this programming language and examines how Java can control and read GPIO pins. Read the Article
Windows on the Raspberry Pi
In 2015, a special version of Windows 10 was released that runs on the Raspberry Pi 2. In a short series, software journalist Tam Hanna took a look at what it could do for the electronics hobbyist. Ready the Article

Raspberry Pi as a KVM Remote Control
KVM stands for keyboard, video, and mouse, and whoever has access to it can remotely control a computer. Using the clever PiKVM software and a Raspberry Pi 4, you can inexpensively control a PC and other devices via the Internet without having to install software on the remotely controlled computer. PiKVM also enables the provision of virtual disks, so that a computer can not only be controlled and maintained remotely, but also a complete reinstallation is possible. Read the Article
