 For the presentation of the work, I can imagine an exhibition in which on the one hand the machines and other working models created on the way to them are shown. The second machine I have described can also be described in a video work in which one can establish a stronger connection to the analyzed place and compare the two sound worlds.

+==Project Documentation==
+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>

+<q>
+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>

+<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>
+[[File:structure_TODAN1.jpg|400px]]<br>[[File:TODAN_Schaltplan1.jpg|400px]]<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 rotating 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.
