International Space Station on the Raspberry Pi 2

Having a play with ISS above, a very cool Raspberry Pi image for the raspberry pi 2, to view international space station cameras, tracking and info.

ISS above website

However not having access to rasp-config setting and no GUI to update I used my phone with SSH juice (lots of similar apps available) to update and make the connections a bit safer as follows.

Your IP address will be shown on the screen a few seconds after starting ISS above.

sudo apt-get update 
Updates your raspberry Pi.

sudo apt-get dist-upgrade
Upgrades your Pi and installs security patches.

sudo apt-get install ufw 
installs UFW (uncomplicated fire wall) .

$ sudo ufw default allow
This sets the default policy to allow, this will allow your connection from any port to your Raspberry Pi after your firewall is enabled.

$ sudo ufw enable
Starts the firewall.

$ sudo ufw allow 22/tcp  
Allows incoming TCP connections to port 22 (for SSH).

$ sudo ufw allow 80/tcp  
Allows incoming TCP connections to port 80 to access settings via a browser.

$ sudo ufw default deny
This changes the default policy to leave only used ports open. 

$ passwd
Change the default "raspberry" password to something less obvious. 

$ sudo reboot
reboots your Pi.

Windows 10 privacy


Here are some privacy adjustments I made before connecting to the internet and having Microsoft spy on me too much!

I will list the options as they appear in the settings and menus, so you can follow along with another device.

After downloading/installing (this takes ages) choosing location/keyboard layout, you will get to the internet settings screen, don’t connect yet, choose the option to skip.

Select custom settings - (don’t choose express settings.)

Browser and protection screen - switch everything to off.

Personalization screen - switch everything to off.

Make it yours screen - skip this step.

Now Windows will load into the desktop environment, once Windows 10 is loaded, go to Settings - Privacy and disable everything.

General settings - switch all to off.

location - off.

Speech, inking and typing – Turn off Cortana.

Feedback to Microsoft - never in the first box, basic in the second box.

Windows update - automatic update, then open advanced settings - how updates are delivered - switch off update from more than one place.

Windows defender - real time protection - on. cloud based protection - off. sample submission - off.

Network and internet – Wi-Fi – Manage Wi-Fi – Wi-Fi sense – both off.

Then go to the search bar and type in cortana, in cortana settings disable it by switch both options to off.

You can connect to the internet now.

Open your browser - in the Edge browser go to settings - advanced settings – switch on do not track, and block third party cookies.

If you are signed in with your Microsoft account, Microsoft will store your information, passwords, Wi-Fi password etc, if your not happy with this, sign in with a local account (just a user-name) not linked to an email account.

Family Friendly

Open DNS family friendly works by replacing you Internet service provider's domain name system (DNS) servers.

You can either change the DNS in your router settings, so all devices that connect to it automatically use open DNS, blocking adult, phishing and anonymity websites.

Or change to open DNS in one or more devices directly, so you will be blocking adult websites with only the the device/s you chose to use it on.

This will not stop all unwanted content or viruses, but will block all known websites that have adult or unsuitable content. So please be careful what you click on, and email attachments that you open. 

Router settings:
Log onto you router by entering 192.168.1.1 into your search tool-bar, then enter your admin user name and password, usually admin, admin or admin, password. Then go to DNS settings, usually under advanced or dynamic DNS settings, then replace the primary and secondary DNS servers with.

Primary        208.67.222.123
secondary    208.67.220.123

Then save your settings, reboot your router and check to make sure adult sites are blocked.

PC settings:
go to settings/control panel, then network settings, then replace the DNS servers with the ones above, then save your settings, reboot and check adult content is blocked. 

The single PC option is great for a children's PC.

More router security settings can be found here.

Inspirational children

I recently had the opportunity to talk to a class in a local primary school about the Raspberry Pi computer and basic programming with Scratch and Python.

What a great class of children!

I'm a shy person so public speaking is something I have always avoided, the children quickly put my nerves to calm with such great input and questions, I done it for the kids to learn and have fun, but my thanks truly goes to the children as I have gained lessons from them in the process.

Here's an outline of the talk:

1 - Introduction to the Raspberry Pi

2 - Coding what it's used for / how it's used / coding in everyday life + a demonstration of traffic lights with LED's

3 - Other Raspberry Pi projects (Bird box camera, nature camera, weather balloons in space)

4 - Robots, brought my one along for a demo (should have got the kid's to name it!)

5 - Hacking Minecraft, this went down really well, they would have been happy doing this for the rest of the day.

A big thank you to my good friend Les Pounder for help and ideas for using Minecraft to inspire. (http://bigl.es/

How to text install crunchbang 11 (waldorf)

When trying to install CrunchBang 11 on my Asus 701 4gb eee PC, there was no option to text install, this is because of a bug in the Debian installer, this is how to fix the problem.

Install CrunchBang 32 bit to a USB drive, (I used USB installer in Linux mint).

Boot PC and press ESC to enter boot order menu, then select boot from USB.
Once loaded, use curser keys to highlight install. (Don't press enter yet) then press tab key, this will bring up the installer commands, press the space bar once then type "vga=normal" then press the space bar once, then type "fb=false" then press enter.
This will start the text install, where you can follow the instructions, to install as normal.

Windows XP alternatives

All versions of windows XP will no longer be supported from April 8th 2014

This means there will be no more system updates and security vulnerabilities will not be patched (made safe) leaving XP unsafe to use on the internet.

The bad guys/girls will be ready and waiting, knowing that there will be plenty of XP machines online to exploit, so ignoring this will leave you open to all sorts of nasties.

I’ve seen a few anti-virus companies offering support for a fee, I’m not sure how secure this will be, alarm bells are ringing with me.

What can we do about it?

First of all, back up all your documents/photos etc to a safe place.

You can use an XP machine safely offline, such as a word processor or games machine, if this suits your needs.


You could upgrade to a later windows operating system as long as your computer has the correct specifications to run windows 7 or 8, in my opinion windows 7 is much more user friendly, stable and sensibly laid out if you can get hold of a copy.

You could simply buy a new computer with a later version of windows or an Apple computer.

You could leave windows and buy a chrome-book, they are cheaper than a windows machine and although they have their limitations, they also have lots of advantages, such as more secure and easier to maintain.

Or my favourite option, recycle and install a free version of Linux onto your computer, this will completely wipe your windows operating system and all your files, but if your computer will be no good anyway, what do you have to loose?

These are my favourite Linux distros:

1 Xubuntu: (xubuntu.org) a lightweight version of Ubuntu, good for a Linux beginner, easy to use.


2 Peppermint: (peppermintos.com) again good for beginners, easy to use menus, Google chromium browser as default, good for older hardware.

3 Crunchbang: (crunchbang.org) Lightning fast, minimal, fuss free, not aimed at the beginner, but learn a few Linux terminal update commands and you will be up and running in no time.

4 Mint: (linuxmint.com) cinnamon version is beautiful looking, very easy to use, not as lightweight as the others so will work better on more powerful PC’s (4gb ram or higher).

Loads more versions of Linux can be found on distro watch (distrowatch.com).
