Pi-Birdies! Part VII - Priorities

...what can I say....

 
 
I spent some time writing a python code for streaming to a server (which I shall post as soon as it is completed).
 
And then I played around with the desktop settings of Raspian to be more "spacey"....for my Feng Shui and well for a myriad of other reasons, including: should I forget what it is that I do professionally, I now have to only turn on my Pi and stare at the desktop in oblivious ignorance! Soooo simple! :-)
 
And this what I have come up with so far in terms of the nesting box. I will not refine it at the moment and will play it by ear as I construct it. I have to add some inner structure to it as I will be making both the front and sides "openable".
 
 
 
Oh!...and....a happy and serene 2016 to all!

Pi-Birdies! Part VI - Technobabbel

Trying to write a python programme to stream to a server and hence am reading up on network services, protocols, sockets and the likes and then trying to explain this to someone whilst myself trying to understand why it is not working..... what ensues is definitely technobabbel (https://en.wikipedia.org/wiki/Technobabble) on my part.... that is what it feels like at any rate!

Someone remarked: "sockets are small socks"....

Pi-Birdies! Part V - parts which are still missing

Just a few quick and rough annotations as to things that I wish to add:

Camera Multiplexer - for more than one camera (http://www.ivmech.com/)
very much like so: https://hackaday.io/project/2847-ivport-raspberry-pi-camera-module-multiplexer, requiring https://github.com/ivmech/ivport

GPS - ok just a gimmick.... because I can for the moment - bringing birdies and space together is a thrilling idea - but mostly for the future when nesting boxes will populate the woods and scientists need the GPS position of the boxes. At any rate this is what I intend to do: https://learn.adafruit.com/downloads/pdf/adafruit-ultimate-gps-on-the-raspberry-pi.pdf

Bluetooth - ...as already mentioned before

Sensors - of various types...

Pi-Birdies! Part IV - RPi-Cam-Web-Interface and JUICE: ESA's JUpiter ICy moons Explorer

And another thing....
I discovered this in my attempt to avoid programming a whole web-interface! Open-source is indeed something quite fantastic.

It is called the RPi-Cam-Web-Interface and it is great.


So all I do is:
ifconfig .... check out the ip address ... http://192.168.1.4/ ... and voila' ...

...off to Jupiter and its moons....

 
..which brings to mind ESA's JUICE Mission http://sci.esa.int/juice/
 
The mission "The JUpiter ICy moons Explorer (JUICE) will perform detailed investigations of Jupiter and its system in all their inter-relations and complexity with particular emphasis on Ganymede as a planetary body and potential habitat. Investigations of Europa and Callisto would complete a comparative picture of the Galilean moons." [http://sci.esa.int/juice/50068-science-objectives/]
 
"The JUICE mission will address two themes of ESA's Cosmic Vision programme: What are the conditions for planet formation and emergence of life? and How does the Solar System work?"

I am quite exicted about JUICE and in addition to the wonders of space science it also reminds me of "Farmer in the Sky"...

...a 1950 science fiction novel by Robert A. Heinlein about a teenaged boy who emigrates with his family to Jupiter's moon Ganymede... [https://en.wikipedia.org/wiki/Farmer_in_the_Sky]).

...for, as an esteemed colleague pointed out to me this year at the IAC, we are Solarians....

Pi-Birdies!...and more

2015 is coming to an end....an amazing year with several surprises and rollercoaster rides! I loved every bit.

My nesting box activities did however "suffer" from my other "adventures", but!....I had time to reflect on a few modification which I intent to make.

I wish to construct a nesting box which is more modular. More easily adaptable to configuration changes and adjustments I might have to make to the optical unit as the seasons progress.

The second thing I wish to implement is a simple, one-off solution for all the nerdiness I wish to install in the nesting boxes. By this I mean pressure sensors, temperature sensors, humidity sensors and the likes. The solutions I had so far, for lack of time, and for lack of me being a dedicated electronics person, were improvised solution requiring multiple platforms. One for the cameras, one for the temperature sensors, one for the lighting: a high maintenance configuration which, in case of lack of time, ended up suffering because I ended up dedicating my little spare time to other things.

And this is where the pi-ness comes in!

I eyed the raspberry pi (https://www.raspberrypi.org/products/raspberry-pi-2-model-b/) as my solution!

It struck me a near-perfect as can be for my needs....including the non-negligible fact that it is open-source, allowing me to profit from all the genial minds out there improving the platform for the most varied of applications.

So this is how I now plan to turn the "birdies" into "pi-birdies".....

I decided to indulge into this endevour on the 12th of Decemeber. Ordered everything I thought I might need the same day and by the 18th (which was my last day at home prior to a weekend with my PhD Students and then some work-related travel) I had all I needed.

And this is how it continued....

Step 1: take picture....and put the basics together...

 
Step 2: install NOOBS from micro SD card...

 
 
Step 3: excitement at booting and ensuing check that space activities had not continued without me in the meantime...

 
Step 4: first light....

 
Step 5: first senses....

 
Step 5: IR vision test...



And then, and then I killed the internet.

I am only kidding, as the only thing I did manage to do was kill internet on my pi.
The thing I want to do is have a nesting box that can transmit information - optical and sensory - via wifi but at the same time be an isolated, stand-alone system. A curious soul passing by can then just tune in and check what is happening inside.

So I wanted to set-up a point-to-point wifi connection, but I kind of got stuck as I wish the two things to be functional in parallel. Now, I might sound like I know what I am talking about, but I don't. So for now I am going to leave things as they are and add bluetooth capability and then decide at a later stage, as.....

...my main priority is to have an optical  stream with overlayed sensory information ...very much like this:


And this is the current state of affairs at the Pi-Nest!

As for other thoughts.... this gave me something to chew on:
"It's the way a man chooses to limit himself that determines his character. A man without habits, consistency, redundency - and hence boredom - is not human. He's insane." [The Dice Man, George Cockcroft].
