During the image and code module I tried to find a way to show how the wifi within my own house works. I found an application that gives a certain signal a color and specific sound. Green is for a good reception, red for a bad reception etc. With these elements I tried to find out where in my own house I can find the best reception. What I noticed was that trying different routes and ways to document this process, when I did the same walk again the signals were completely different. This sparked my interest even further. I tried to make an automated website that updates regular with new signal updates, of course this was too advanced for me yet, next to my best efforts at a website which changes when moving the cursor, I made a simple example with photoshop to show what I was thinking of. This shows the colours of the places and then a second bar which shows the second walk - and the differences within the signals. 

Based upon these small experiments I know now that I want to build my own signal identifier, which I'm currently trying to find a good basis for, meaning: will I use an arduino, or a raspberry pi, what else do I need, what kind of coding will be the best etc. I hope to find a way to analyse wifi signals, why do they change and what effects them and the other way around. How can we see these signals with our own eyes?
