Logitech K810 Keyboard


The Logitech K810 is a wireless, back-illuminated keyboard. You can use it with any bluetooth-enabled device. It even allows you to pair up to 3 devices and switch between them with just one keypress. Besides the excellent ergonomics, it looks fantastic and is easy to use in a dark environment due to the back-illumination. The keyboard automatically turns off the backlight when the keyboard is not in use. A proximity sensor magically reactivates the backlight when you approach the keyboard with your hand. To further save energy, the back-illumination can be dimmed or even turned off.

Home Cinema – Part II


When I think about home cinema, the first thing that comes to my mind is a big screen. It ultimately distinguishs a standard TV setup from a home cinema.

Home Cinema – Part I


This is the first part of how to build your own home cinema. Well actually, I will not tell you how to ‘build’ it, but rather help you to choose the right components and give you some hints.

Before we start, I’d like to try to answer one of the most common questions that comes up when someone asks me about a home cinema: “How much do I need to invest?” I will discuss each component separately in the following article, but to give you an indicative value beforehand: If you start from the ground up (without any components), then you’re probably looking at 2500 to 4000€ for a descent setup – without major room optimizations, seating furniture or other extras! This is just my recommendation and does not mean you can’t realize a home cinema for 1000 bucks or less.

There will be 3 parts in total:

  • Part I: Room
  • Part II: Video
  • Part III: Audio

These are the three essential parts of every home entertainment system. We start with the first and obviously most important part, the room which will accommodate your home cinema.
