New Raspberry Pi 3 Model B+

First of all, just have a look at this new model in the picture below (kindly taken from the raspberrypi.org release article). Looks familiar, isn’t it?

Now, let’s look directly at the hardware and understand what are the main features, the difference from the previous RPi 3 and what benefits the users are going to get, using this new model!

New Features

As mentioned earlier, this is the first company’s 64-bit product. And it seems that RPi 3 B+ has a networking bias due to the connectivity which gained pretty much attention in this new product version. Thus, the main technical peculiarities of this product are:

  • CPU: Cortex-A53 1.4GHz Quad-Core ARM (there are also versions with the processors of 2.4GHz and 5GHz)
  • LAN: Wireless, dual-band 802.11ac
  • Bluetooth 4.2 (also wireless)
  • Ethernet: Gigabit USB 2.0
  • Power-over-Ethernet
  • PXE network and USB mass-storage booting
  • Cooler

It’s worth noting, that CPU has become a little bit faster (+ 200MHz). The product is built upon BCM2837B0 Broadcom processor, which includes power integrity optimizations and a heat spreader. This feature has become especially valuable since the last news, which annonced adopting the Raspberry Pi devices for artificial intelligence (see the article on Electronics Lab).

Speaking about the Dual-band wireless LAN and Bluetooth, they are provided by the Cypress CYW43455 chip, connected to a Proant PCB antenna (just like it was used for Raspberry Pi Zero W). This gives the company an opportunity to certify the board as a radio module, meeting the FCC regulations.

The updated LAN7515 (comparing to LAN951x, used in previous models) supports Gigabit Ethernet now and significantly increases the wired and wireless network throughput.

The implementation of “magjack” now brings the relevant signals to a new 4-pin header. Also, the launch of a new PoE HAT for generating the power from the 48V PoE supply will be shortly announced as well!

Power Efficiency and Cooling

Obviously, due to all the improvements mentioned above, Raspberry Pi 3 B+ increased the level of power consumption. And with that, the hardware has gained better peak and longer-duration sustained performance. To achieve this, the Raspberry Pi engineers improved the power integrity and accuracy of their new MaxLinear MxL7704 power management integrated circuits.

With the temperature accending 70°C the smart thermal management technologies are implemented to decrease the core voltage so that the next 80°C thermal throttle becomes longer reachable in time. With that improvement, Raspberry Pi 3 B+ can run faster at a lower level of temperatures. This is clearly displayed in the graph below (which has been borrowed from the Raspberry Pi Foundation blog post).

And by the way, to cope with the increasing temperatures of a new model, by adding the board its own small cooler, which is quite convenient.

Final notes

The new model of Raspberry Pi, which has been recently released, is not that big technological “jump” from its predecessor, but still offers great features to make RPi 3 B+ worth purchasing. Among them, there are improvements which have been really liked by the community such as better performance, increased Ethernet throughput and smarter thermal management. In addition, all this is for the price of the previous model and it makes the deal even more attractive!

Also, a larger field for doing different projects on RPi appears now and thus, the demand for Raspberry Pi software tends to grow as well. With the new Raspberry Pi features, makers and developers may widen the range of software they use on Raspberry. And ExaGear Desktop can help them to bring the necessary applications to this ARM-based device.

We’ve got a lot of use cases when ExaGear helps to make up a Plex media center or manage music with Spotify on Raspberry Pi. The cases of running Teamspeak and Teamviewer on Raspbian or creating a MetaTrader bot for automatic Forex trading on Raspberry Pi and many others.

Moreover, with ExaGear Desktop, you can run almost any x86 app on any Raspberry Pi models as well as on the new Raspberry Pi 3 Model B+.

 

How to set screen resolution for VNC Server

Here is how you change the screen resolution for VNC Server on a Raspberry Pi.

Go to terminal and type:
sudo nano /boot/config.txt

Find this section of the config.txt file:
# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=2
#hdmi_mode=16

Change to this to set the default resolution to 1280×720:
# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=2
#hdmi_mode=16
hdmi_ignore_edid=0xa5000080
hdmi_group=2
hdmi_mode=85

These values are valid if hdmi_group=2 (DMT):

Root File Browser for Raspbian Jessie

I am often asked how to run the file browser with root privileges on a Raspberry Pi, here are the instructions.

Typing gksudo in Terminal and then hitting enter. A window named Run program will pop up.

Then typing pcmanfm on the Run text field. Pressing ok. Always use caution when running the file brower with root privileges, you can easily break your system if you don’t know what you are doing.

Open Source Media Center

I’ve started using OSMC for my Kodi No Limits Magic builds. The OSMC image for Raspberry Pi 3 is an excellent choice for building media centers since everything you need is included in the image making setup fast and easy.

OSMC (Open Source Media Center) is a free and open source media player based on Linux. Founded in 2014, OSMC lets you play back media from your local network, attached storage and the Internet. OSMC is the leading media center in terms of feature set and community and is based on the Kodi project.

Vero 4K is OSMC’s flagship device. It’s designed and manufactured by OSMC developers to ensure that users can get the best OSMC experience on purpose built hardware and enjoy the very best performance and support.Simple and easy to use.

Although OSMC is based on Linux, you don’t need to have any experience with Linux to get it up and running in the way you want. Everything is easily managed through the OSMC interface. For those that do want to tinker, you have the full Debian repositories (which bring over 30,000 packages) at your disposal.

It’s free and open source.

It’s not just free in price. You’re also free to do whatever you want with the software. OSMC is licensed under version 2 of the GPL. Anyone is free to use OSMC and its code, but should they make any changes, they should contribute them back to the OSMC project. This fits in perfect with our development philosophy. OSMC is great because it’s built on great software with the same values.

OSMC installs in a matter of minutes

We’re proud that you can install OSMC on a number of devices (find out which ones here) in just a matter of minutes. Our easy installer is what separates OSMC from other media center products out there. We’re always happy to help as well if you run in to any trouble.

Get easy updates and apps

You’ll receive regular updates which make OSMC better every month. You can choose when (and if) you’d like to install updates, as well as install new apps via our app store. Everything in our app store is free. Get a torrent client, web browser and TV tuner up in seconds. All from your remote.

OSMC has a big community

OSMC has a large, bustling community full of users willing to help newcomers get up and running. We’ve also got a wealth of resources to help you get the best of OSMC.

Play anything from anywhere.

OSMC can play all major media formats out there and supports a variety of sharing protocols so you’re guaranteed to be able to stream from other devices. OSMC can stream media and serve files to other devices as well!

It looks fantastic.

A great deal of love and care has been put in to engineering OSMC to be the best media center out there. OSMC’s look and feel is no exception. OSMC is more than just a media center: it’s an experience. Don’t take our word for it though. Give it a spin!

OSMC wouldn’t be where it is without an excellent team behind it. OSMC is developed and maintained by a group of volunteers in their own time. This hard working team bring a multitude of skills and expertise to the table and ensure OSMC stays the leading media center experience out there.

We would also like to thank our community staff. These include translators, forum moderators and everyone else who helps move the project forward.

OSMC would also like to thank all upstream developers for their contributions, in particular Team Kodi and the Debian project.


Ubuntu Mate

If you are looking for a good Raspberry Pi OS for general computing Ubuntu Mate is the way to go.  Ubuntu MATE is a stable, easy-to-use operating system with a configurable desktop environment. It is ideal for those who want the most out of their computers and prefer a traditional desktop metaphor. With modest hardware requirements it is suitable for modern workstations, single board computers and older hardware alike. Ubuntu MATE makes modern computers fast and old computers usable.

If you are new to Ubuntu MATE, or only casually acquainted with Linux based distributions, it can be difficult to understand how a Linux operating system compares with other computer systems that you may already be familiar with. Hopefully this page will help demystify Ubuntu MATE for new-comers.

Ubuntu is one of, if not the, largest deployed Linux based desktop operating systems in the world. Linux is at the heart of Ubuntu and makes it possible to create secure, powerful and versatile operating systems, such as Ubuntu and Android. Android is now in the hands of billions of people around the world and it’s also powered by Linux.

Ubuntu is available in a number of different flavors, each coming with its own desktop environment. Ubuntu MATE takes the Ubuntu base operating system and adds the MATE Desktop.

The MATE Desktop is one such implementation of a desktop environment and includes a file manager which can connect you to your local and networked files, a text editor, calculator, archive manager, image viewer, document viewer, system monitor and terminal.

MATE Desktop provides an intuitive and attractive desktop environment using traditional metaphors, which means if you’ve ever used Microsoft Windows or Apple Mac OS, it will feel very familiar.

The MATE Desktop has a rich history and is the continuation of the GNOME2 desktop, which was the default desktop environment on many Linux and Unix operating systems for over a decade. This means that MATE Desktop is tried, tested and very reliable.

Powerful Applications

While MATE Desktop provides the essential user interfaces to control and use a computer, Ubuntu MATE adds a collection of additional applications to turn your computer into a truly powerful workstation.

Productivity & Entertainment

Firefox

Safe and easy web browser

Thunderbird

Email client with integrated spam filter

LibreOffice

Full-featured office productivity suite that is Microsoft(R) Office compatible.

Rhythmbox

Music player and organizer

Shotwell

Digital photo organizer.

VLC

Play, capture, broadcast your multimedia streams.

Naturally you’ll also find a firewall, backup application, document/photo scanner and printer management all included in Ubuntu MATE. And this is just the start. The Ubuntu Software Center includes thousands of applications suitable for just about any professional or recreational pursuit.

Games

In recent years Linux has become a first class gaming platform thanks to Valve bringing the Steam platform to Linux. At the time of writing Steam has thousands of high quality indie and AAA titles available for Linux. Ubuntu MATE is fully compatible with Steam for Linux.

While Steam is a major step forward for gaming on Linux, there are also many high quality and enjoyable Open Source games titles available for Ubuntu MATE via Software Boutique and Software Center. It doesn’t matter if you like flight simulators, motor racing, first person shooters, jump and run or card games, you’ll find something to keep you entertained.

Open Source

Open Source Initiative

What Linux, Ubuntu and MATE Desktop all have in common is they are Open Source. Open source software is software that can be freely used, changed, and shared (in modified or unmodified form) by anyone. In a nutshell Ubuntu MATE is free, in the truest sense of the word.

Although you will find some versions (distributions) of Linux for purchase, the vast majority are provided free of charge, like Ubuntu MATE. Open Source software is licensed in a way that allows anyone to give it away for free, no strings attached. For example, the license gives any member of the user community the freedom to use Linux for any purpose, to distribute, modify, redistribute, or even sell the operating system. If you do modify and then redistribute Linux with your modifications, you are required by the license to submit your modifications for possible inclusion into future versions. There is no guarantee that this will ever happen, but if you have made it better, then your changes just might be included in the next release of Ubuntu MATE.

This is how we can continually improve and grow without having to charge our users money. Many of the users of Linux are corporations that use the operating system to run their businesses, or include it within their products. Many of these corporations provide fixes and new features for Linux as they use the software for their businesses. These improvements are given back to the Linux distribution and the software improves as a result.

Unlike Windows, and OSX, Linux is not created and supported by just one company. It is supported by Intel, Redhat, Linaro, Samsung, IBM, SUSE, Texas Instruments, Google, Canonical, Oracle, AMD, and Microsoft. Over 4,000 developers contributed to Linux over the last 15 years.

Whether you are a home user of Ubuntu MATE, a Ubuntu MATE software or application developer, or an employee of an organization that uses the operating system, you are a member of the Linux and Open Source communities and benefit from the efforts of the developers who contribute to Ubuntu MATE and its related projects, Linux, MATE, and Ubuntu. Members of the community can and do run Linux on almost any hardware, from the prettiest Macbook to the cheapest netbook, from the newest Chromebook to some very old machines designed for Windows, and from the most powerful Internet servers to the smallest smart thermostat.

No Limits Magic Build Kodi Krypton

No limits Magic version  is one of the best Kodi builds v6.1 available. It has a very nice layout and uses the Aeon Nox 5: Silvo Skin. It also has all the latest and best video add-ons installed such as Covenant, Bennu, BOB Unleashed, Elysium, Quantum, Stream Army, UK Turk Playlists and many more. The install for Kodi No Limits Magic build has changed since it was first introduced. The popularity of the Build slowed down the servers which gave long download times. Echo wizard gave a better quicker solution but has closed down recently moving on to other things. Using the No Limits wizard is now the best way to install the Magic Build and has all the Build versions including Fire Stick options. Using a good VPN with Kodi is always suggested for privacy and security. If you need a good low cost VPN to use with Kodi try BTGuard or ipVanish, they both have speed servers with no throttling or logs. For non-techies its easier to setup a proxy server. I use TorGuard for my proxy, they have good speed and also keep no logs. I have it installed on a Raspberry Pi 3 with OSMC  and my testing have produced very good results. It does occasionally lock up the system which requires a hard reboot but other than that I have not found any major bugs. As always you can contact me if you require any assistance setting up a Kodi box or if you don’t want to mess with it I can build one for you.

Pi Cluster Super Computer

pi cluster super computer

The Raspberry Pi family of single board computers transformed education and has become one of the drivers of the Internet of Thinks revolution. These boards are low-cost, well-featured, and easily available. So what do you get when you take a bunch of Raspberry Pi boards and wire them together? An incredibly cheap and surprisingly high performance parallel computing system that’s not only valuable in education but can also solve some useful, real world problems.

In my case I am in the process using my cluster into a Turing Bombe to break the Kriegsmarine four rotor  Enigma M4 machine.
