Etcher: the app you need to record operating systems for your Raspberry Pi on an SD


When you buy one of the versions of the Raspberry Pi board, one of the things you have to do is to prepare the SD memory card to have a bootable operating system compatible with this SBC board. For that to be possible there are many tools, although one of the most popular and that I recommend is Etcher or balenaEtcher. With it you will have everything you need to prepare your OS in the SD in a very intuitive and fast way.

You should know that there are a lot of operating systems that are already compatible with the Raspberry Pi board. Many GNU/Linux distributions already support ARM and can work well on the Pi. You also have other open source operating systems that are not based on the Linux kernel and are special to the Raspberry Pi, such as RISC OS, RaspBSD, etc. You can even find some for specific use like Windows IoT, OpenELEC for setting up a media center, RetroPi for retro games, etc.

Raspberry Pi 4: new model with many new features

Raspberry Pi 4 Model B

Well, now the Raspberry Pi Foundation has renewed its hardware. There’s a new board out, the Raspberry Pi 4. This SBC (Single Board Computer) has blossomed after the success of the Raspi, and many other manufacturers have taken advantage of the wave to create their own similar boards with the original or with some changes, better performance, new features, etc. But the original Raspberry Pi is still the queen.

How to make a Geiger counter


home geiger counter

Three Milles Island, Chernobyl, Fukushima, and even some on national territory such as the Coral-I reactor in Madrid or the Vandellos-I in Catalonia. There are many nuclear accidents that have occurred throughout history, and despite the terrible consequences, it seems that the issue of radiation continues to raise some attraction. But what few people know is that, every day, we are all exposed to natural radiation, both that which comes from outer space and that which comes from the minerals of the earth…

Well, if you want to measure the radiation around you, in this new guide we show you step by step the procedure of how you can build a Geiger counter, that is, a device capable of measuring radioactivity. Basically, it is a device that can measure particles that impact with the sensor, such as ionizing radiation, that’s why it’s called a counter, since it can count the number of impacts and therefore the radiation level of an object or place.

Raspberry Pi launches its own keyboard and mouse; available in Pi stores

Raspberry Pi keyboard and mouse

When I read this news I couldn’t help but remember a comment made by an acquaintance: they have been taking things from the devices until they turn them into mobiles/tablets and now they are adding things to them again to turn them into computers. But thinking about this I am wrong, since the reason for the Raspberry Pi boards is not exactly to make portable devices. In any case, the famous motherboard company has launched two more products: a keyboard and a mouse.

As you can see in the image above, the keyboard design is striking for two reasons: firstly, because it looks very much like a keyboard that Apple would have designed and, secondly, because it includes its own logo in what in other keyboards we would see the Microsoft logo, an image that, as a Linux user, I don’t like to have in my laptop. As we will explain later, both devices are in two colors, but I think the one that looks best if we want to be faithful to Raspberry’s philosophy is the one they have used in their promotional image: red and white.
