The Ultimate Elements Crossword Puzzle

With great satisfaction I present my latest work of DIY



I think a picture is much better than 1000 words!

Features

1) Manual on / off
to 8 devices in high voltage

2) Timer and clock
Allows you to set a time on and off for each outlet.
In case of power failure the clock will be preserved thanks to a battery.

3) Temperature Monitoring
constant temperature with accuracy to hundredths of a degree (23.55 °), visual display. Ability to display minimum and maximum temperature of the day with time. N-
thermostat thresholds (currently managed only a fourth and less than 3). For example you can set: below 25.7 heater switch on, turn on the fan above 5.26, above the 27 ° and above 28 degrees cooler off the HQI. Delta configurable thresholds.

5) If set
delay after delay, prevent a device from immediately after a shutdown. For example, to prevent the metal halide light up immediately after a shutdown.

6) 2 osmoregulation
Using floating probes allows for the automatic refilling. Report visually mancaza osmosis water in the tank (red LED). In case of lack of water suspended The top up and prevents the pump topping from burning. The delay ensures that top-ups will not occur which could lead to prolonged flooding.

7) Ph
pH monitoring.

8) Blackout
specific to the system a chance to say a device that in case of blackout lights. It is also possible to know the date and time start and end of the last blackout.

9) automatic feeder
I changed my manger EHEIM. Now you can make that is synchronized with circulation pumps, and then go off for 5 minutes.

UI
The user interface is very simple. The menus are numbered eg.

1.Temperature 2.Ph

The same applies to the sub-menu.

both pH and temperature are equipped with self-calibration, respectively, up 2 points and one point.

Realization
I tell you immediately that it was not a walk, for months, the evening after work, I devoted myself heart and soul to this achievement.
The controller is based on an open source hardware for the Italian production called "Arduino" (http://www.arduino.cc/). E'ormai popular in quite as versatile and economical. Featuring onboard programmer, USB port is very convenient to set (for me, a computer).
Many manufacturers have so-called "shield" or cards that are inserted literally sull'arduino equipping of additional features, such as Ethernet, GSM, etc. .. Although powerful
arduino alone is of little use without proper RTC (real time clock), for the uninitiated a clock can keep track of time passing.
Same question goes for the keyboard and display. Before finding the right components I had to try on my skin the most varied problems .. but in the end the components have been identified and wired together.
I opted for a membrane keypad 3x4, 4x20 backlit LCD BLU.
for connections to various sensors for ease of assembly I was directed to common RCA jacks. To connect the power unit I chose a RS232 (serial port).
For the power unit, which is the part which is responsible for driving the output high voltage, I used a pre-packaged form, to have already implemented a pcb without loosing too much head. I inserted the card in a special container with IP66 and RS232 port.
As regards the part of the transducers, ie those components that are used to acquire information from the outside, I used:

For the temperature sensor: LM35DZ
I had to make it 4 probes to identify each kind of problem. Some of the mechanical assembly (infiltration of water) nature of other electronic means (magnetic interference disorders of neon). To end of the probe that came out is really good with very high precision.

for pH I used an amplifier operation at the highest level. On the ph
I studied for several months. After several attempts and more than 10 different types of operational I have identified what appears to be the best (mouse secret :-).
Clearly, the probe has a BNC connector, consequently, the unit was equipped with BNC

similar to the floats I used the common floating vertical coupling through rca very comfortable.

Reliability

To date, the unit is running on my tank for about 1 month and I must say that is behaving very well, except for small bug that I am making from time to time. The Arduino is very good, it really is a gem made in italy.

Future

Unfortunately for the study of the investment component has not been recently, so have a little catch up with developments.
Anyway the next thing I will realize is the combination of SMS alert and management of the redox probe ...
If anyone is interested in participating actively in the project, being willing to invest time and money can contact me by email.

2005 Elantra Is Overheating

Electrical equipment

As for the electrical part I for a long time to study.
First, the mobile division of the electrical / hydraulic part, has allowed me to achieve greater security against short circuits caused by splash on thorns. I also decided not to put anything on the floor of the cabinet in order to avoid electrical problems in the event of flooding. I have to do it with the cabinet of a cabinet hung on the wing and back to the heavy metal halide ballast, I used a medium (ikea) drilled in order to obtain a good heat dissipation.
But let's get to the real power ...
I used a cabinet with 36 modules ... and yet many seem to believe that they are always too short!
The first line I have taken for use in the control unit which I'll discuss shortly in a dedicated post. The second line is left free for private use of automatic control, the last line is partly free and partly related to the good old and very reliable thermostat. For reasons of cost per hour I did not expect any breaker in the future but I do not exclude the possible addition.

And finally water and rock

I tried to create the terraces rather low because the tank is low and wide and deep enough. I also tried to create the ravines where fish can hide .. I'm not yet 100% happy but we say that provision does not go bad as before ..



But since I'm pleased with the burglary and refer back! :-)
2 hours last night hands in the water and the result satisfies me loooong more. Of course the water is still dull and need to take into account what time I turned on the light, but I think he knows that, compared to before I changed many things.

When will the oil? My living will

When will the oil? The question has no simple answer. Indeed : the question is as widespread as misplaced. The oil will not end, probably, is rannicchierà ever deeper, sliding under the land and oceans on ancient, obscure. Ends, however, the possibility of human technology to capture: the transaction costs, slowing down the mining market, and this is in fact already happening on a massive scale.

According to the 'Association "ASPO" peak oil, ie the maximum value of oil extraction at the lowest price, exceeded his china in 2005, and the -down is initiated, inexorable and totally unpredictable in its stages.

course is linked, without exception in this global scenario, the economic crisis. Several British and Canadian oil companies have already applied for state aid to their countries and our own ENI has withdrawn its projects in Alaska, launched last year. In Nigeria, the giant Shell is abandoning their fields because the local guerrilla resistance, fueled by anger at the havoc caused environmental and social over the years by international oil companies, is costing too much more than the meager results counted in barrels. The collapse of banking systems hinders even the investment in alternative energy, in a dizzying carousel. Meanwhile, in Italy, the electricity consumption increasing by 1.5 year and talk, very inappropriately, nuclear power, while the more enlightened governments like the U.S. or the Norwegian link independence from depletable sources, whose order is clearly horizon.

These themes were discussed, a few nights ago in Milan, during an evening of film clubs in Chiamamilano, dedicated to the electric car and sustainability Energy Efficiency: " Who Killed the Electric Car? .

Who Do I Write To To Cancel La Fitness

I decided to make public my living will, which I wrote at the height of my mental and physical abilities. I do so following the decision of the Italian government to prohibit the suspension nutrition and hydration, written decree to prevent the father of Eleanor Englaro to let go of his daughter after seventeen years of vegetative state artificially supported. For some time, since when Giulio Mozzi launched the idea on vibrissae bulletin, I thought to publish it. Today it seems inevitable.

Sometimes I think about death. It happens occasionally, when the mind constructs reality next hypothesis: not a fixed idea, and perhaps twenty-five years is a good thing. I learned that it is wiser to look death in the face to try to understand it for what it is, a common human destiny. I think I feel more serene, despite the discomfort of thinking from the inevitable. The Buddhist doctrine says that the first truth of life is the existence of suffering is called the noble truth , and rightly so. E 'noble because it leads to a clear awareness, that - that my experience - helps avoid the anxiety of the future: it is worthy to be known, taught to accept and allow to dissolve the suffering. Why make their own living wills seems to me an act of conscious civilization. Then make it public is a way to emphasize the legal limbo of unconsciousness in which our society is compelled today.
few months ago I learned that this year I will have to undergo spinal surgery. I am confident that the operation, while challenging, will be fine. I'll close who loves me. However, the possibility of an error on the part of medicine and there is always convenient to put them into account. So, typing these words, I also think it is inevitable that this experience that I will do next.
may happen that one day this year, as the next, as in ten, twenty, thirty, forty, I no longer have to find a way to express rationality, feelings, instincts, and even I think is called state vegetative state, and you will not, presumably, reversible. If you ever happen to ask people who are close to me and are in a position to decide whether or not to pursue this was not to be but make the best decision, made on behalf of their respect to my beliefs and their beliefs. I ask for courage and awareness. The aggressive treatment on someone who will never draw a any real relief because it kept alive (non-conscious) only by machines is not the choice I would do to someone I love: after the time required (which will tell the individual event and medicine, and the empirical evidence) for identifying the conditions stable, after the time required for the acceptance of a situation now final, I find it fair that you decide to go ahead with the natural cycle of life and death.
I'd like to die at home, not in the hospital. I would like my organs were donated to those in need and would like to be cremated. I wish there was peace in doing this, despite its weight, you should live the present, not the past. Thank you, thank you.

Where is the culture in Milan? Jaar, "Questions" and Cox 18

LONDON. Discuss and write about culture in Milan in the days when one of the centers free of the metropolis, the Cox 18, is cleared by methods old and unhappy, raises doubts about the heavy awareness of this city against its social, cultural, civil and political. That's why the public project signed Alfredo Jaar, " Questions Questions " , celebrated a few days ago at a conference dedicated to the research culture in Milan and Italy (promoted, theater Litta, by province and foundation Hangar Bicocca), succeeded only partially. Over one hundred days of questions addressed to the inhabitants of Milan, through posters and video screens, panels and postcard, using space usually occupied by advertising, what they left behind in the shadow of the Palazzo Marino? And among the citizens? Doubts? Reflections on stature, but huge invisible, Antonio Gramsci, and Giuseppe Ungaretti Pierpaolo Pasolini? Maybe. They have, however, ignored any deep investigation of the critical issues and the conference "We have forgotten the culture?" Has reaffirmed the essential ambiguity. In his homeland, Chile, horrible years of the Pinochet dictatorship, Jaar Santiago had started filling up with words: "Are you happy?", he asked, a little 'a bit spontaneous' rhetoric, with his compatriots. "Questions Questions" has dropped the same formula in the mass media dictatorship that Jaar, first, to recognize the Italy of today. "What is culture? policy needs culture? Culture is social criticism? Culture, where are you? "Was read for months, and white letters on burgundy background night, on squares and streets, with trams and subways, buildings and monitor. And again: "In Search of Pasolini in Milan ...";" The culture of the emergency ..."; so on, in a chain of microprovocazioni. Many eyes were raised to read, to suffer, and a few to answer. Jaar did not seek answers: "Through these actions I wanted to work in the shadow of three masters, Gramsci, and Pasolini Ungaretti - told the Litta - to penetrate the system anywhere in its cracks, and generate an image of change through public space . Of change has never been read and written so much at least thirty years: "The culture has imagined a Barack Obama even before it existed one. Culture is powerful, "he chanted Jaar. A power, both positive and negative if, as has sharply underlined the anthropologist Marco Aime, among Guests at the conference, the term has come to replace the culture of twentieth-century race. "We are witnessing acts of cultural fundamentalism, which are based on a very simple rhetoric, that dell'ognuno 'at home' and identity as a single identity. But the cultures of the yards are always open. " Just the tools of the shipyard culture penetrate the concerns about the work of Jaar in Milan. To give them a voice was Carolyn Christov-Bakargiev , the next curator of Documenta, which has admitted difficulties in accepting, without a doubt, "Questions Questions": " Let us ask ourselves: is there really still space public or completely privatized? " . Who knows Milan from the nearest node knows how this cultural melting in a city increasingly standardized, intoxicated by private speculation. An intervention like that of Chilean may be unwittingly complicit in the superficiality of knowledge that you hear the collective, interconnected, but it is fragile. What do we mean when we speak knowingly of public art? On this key question was not answered. Only works with high schools in the artistic intentions of Jaar found suitable locations for an educational purpose, of course crucial. So who is right has insisted that all project materials are donated to schools. Training outside the perimeter, a retraining civic there was, and instead of questions of Jaar are back images of the usual publicity. And the talk of the intellectual salon.
