One of the first things I noticed was a little thermometer sign came up in the right hand corner after a short while. A quick Google revealed this meant that the temperature had risen to a level where it may start to affect performance. Decided to buy a case with fan and some heatsinks (about £11 from Amazon). The question was how to monitor the temperature. Knowing nothing about Linux at all led to a lot of googling and I've managed to cobble together something that works.For anyone that knows how to code - be kind I don't, but this works and is literally just a few lines that are easy enough to follow. All info is pulled straight from other peoples work, please don't ask me to explain any of it!
Create a Python script to monitor the temperature of the Raspberry Pi

What I wanted to do then was create a desktop shortcut. The following info applies to anything really that you need a shortcut to.
First thing to note is that when you create a shortcut and double click it that a popup appears saying the file seems to be an executable and asking what you want to do with it. Very annoying and took a lot of Googling to find, so lets straighten that out as a starting point.

One thing I Iearned along the way was that not all the GPIO pins behave the same when rebooted. For example GPIO2 is set to high on boot, which meant that if my Raspberry Pi rebooted the relay I had set up would be triggered until I ran the script to switch it on/off.
GPIO18 on the other hand is set to low by default, so this is what I have used for this example.

Initially I thought I'd be clever and buy components to build my own relay - big mistake as its so much cheaper to buy ready made unless you intend setting up a factory! I bought a pack of 3 relays for under £7 from Amazon, so you're looking at just over £2 a relay that will switch up to 2A and has power and relay state LEDs built in.
There are 3 terminals to connect so you will need jumper wires (female to male, or just female as I stripped the ends that screw onto the relay).

There is a lot of info on how to set up cron, this is the method I chose.
Open a terminal and type:

There are loads of options that can be set, but I feel if you're going to use HDMI you may as well set the output to 1080p 60Hz and be sure it will work on any standard TV or monitor.
To do this I edited the config.txt file as follows:

First make sure your packages are all up to date
sudo apt-get update
sudo apt-get upgrade

Little bit of tweaking and away you go.
The server initially runs on 0.0.0.0:8000 which is great if you are local to the box or have teamviewer installed. I wanted the server to run at boot and use the IP address of the Pi (eth0 or WLAN) Problem is that if you use the IP address of the Pi you need to set the Pi to wait for network on boot (just use sudo raspi-config and select boot options if you want to do that) or it just doesn't work. Also limits you to one interface that you can access it from. So after a bit of work this is what I came up with (googled, copied and pasted - I'm not that clever!)

I'd originally thought I'd dual boot the machine so I could switch between OS's so I proceeded with the install from USB, and just followed the instructions.
Upon completion the laptop would just boot to Windows. Spent a while googling Windows Boot Manager problems and playing with various things, before giving up and deciding to just install Ubuntu on it's own.

Why did I select the minimal install? I figured I didn't want office software or media players etc, so rather than having it all sat there doing nothing but take up disk space, I'd just go with the basics. Little did I know just how basic that is!
Open a terminal and type ifconfig, hit enter - net-tools isn't installed, so you're not going to get any luck there. Long story short I like to work remotely on side projects so I installed what I call the basics as follows.
