The actual project developed differently from what I planned to. This is why you find a huge difference in between the proposal chapter and this one here.<br> | |||
But the descriptions will not be discarded. They will be used for upcoming projects, like in my thesis.<br> | |||
Still, the work according to this class is based on the described thoughts, ideas and readings:<br> | |||
Despite various other cycles that influence processes in ecosystems, the day/night rhythm is very present and <br> | |||
divides all processes into two time domains.<br> | |||
When researching the Odum's approach, it must be noted that these cycles have been completely ignored.<br> | |||
In general, this is a big criticism of their work, which I would like to work out with "Thoughts on day and night".<br><br> | |||
<br> | |||
For a quick impression on the work<br> | |||

What you see here is the confrontation with our ecosystem,<br> | |||
with views from recent decades, with a tree and with the flow of energy.<br> | |||
Can you see, feel, hear the energy?<br> | |||
If it were up to the brothers Howard and Eugene Odum,<br> | |||
which coined the term ecosystem in the 1960s, you should now see here a<br> | |||
perfect analysis tool. <br><br> | |||
But over the years, it has been shown time and again that their simplifications<br> | |||
and mechanical trains of thought cannot be equated with the image of reality<br> | |||
neither on a scientific level nor on an emotional level.<br> | |||
Nevertheless, their research has made a decisive contribution to our<br> | |||
understanding of the interrelationships in nature and continues to provide a<br> | |||
large playing field for our own experiments. <br><br> | |||
So what you see, hear and experience here is the proportion of sunshine<br> | |||
hours on 21st March 2011 compressed to 2.4 minutes. This date is the day of<br> | |||
the forest in the year of the forest. The various circuits, one purple, one<br> | |||
orange, receive their energy from the light, react to it and collect it for<br> | |||
processes at night. | |||

===technical explanation=== | |||
the work consists of two parts. | |||
There is a stepper motor that is controlled by an Arduino and powered by a 12V power supply.<br> | |||
The motor is rotation very slow so that it takes 2:40 minutes for one whole rotation.<br> | |||
Attached to the motor is a translucent disc. (see image).<br> | |||
The rotating disk shades a pin spotlight for an amount of time that is equal to the night hours on the 21st March 2011.<br>During daytime/sunshine hours there are always sections which simulate the shading by clouds on this day.<br> | |||
<br> | |||
The pin spot is lighting on the actual machine of this project.<br> | |||
It consists of two electronic circuits (see image). | |||
The first circuit is powered by the light of the pin spot. It transforms the light into electronic energy <br> | |||
by using small photovoltaic panels. <br> | |||
The energy powers a 555 timer, that then plays a sound. <br> | |||
The frequency of the sound is depending on the intensity of light shining on the circuit, which is detected by a photocell.<br> | |||
this sound stands for the activities that are taking place within an ecosystem<br> | |||
(I am focusing on plants, basically a tree) during the daytime. <br><br> | |||
<br> | |||
The second circuit is focusing on the processes at nighttime in the darkness. <br> | |||
A photocell detects the amount of light and triggers a relay as soon as it gets dark.<br> | |||
The relay closes then another circuit the powers a dc motor on which some metal wool is attached. <br> | |||
While rotationg the wool touches a piezo element connected to a sound mixer and speakers. <br> | |||
The processes at night are represented not only by the visible movement of the engine, but also on an auditory level. | |||
