Test of Turing

Alan Turing considered to be one of the parents of the computer science proposed a test, a method to decide if a machine is intelligent.

The test consists of the fact that a person (the llameremos assessor) will report with the entity that supposedly has intelligence and another person, without direct vision, for example that each of them is connected to a chat.

If the assessor, after rising all the questions that he considers opportune, does not manage to differentiate the human being of the intelligent entity, we will have obtained an intelligent system.

At the moment it has not become possible to spend the Turing test, we continue to the waiting.

Since there does a checker of batteries of 4,8V TTL

Tomeu Simó, we are sent by this Checker of Batteries of 4.8v (TTL). Great thank you.

Electrical scheme:

electrical scheme checker batteries
1.-Materiales

  • A badge of perforated printed circuit of 55x40 mm
  • Integrated circuit LM3914
  • Electrolytic condenser 2.2μF
  • Diode 1N4001
  • Potenciómetros (470 Ω, 100 Ω)
  • Resistances (10K, 20K, 2 of 280 Ω, 100 Ω, 825 Ω)
  • 10 LED's (4 red ones, 2 yellow ones, 4verdes)
  • A box to put the whole set and to hold the leds

To see the attached scheme to know the exact components.

Assembly of the components in the badge:

  • The resistances are mounted, then two potenciómetros, the electrolytic condenser, then the diode and finally the integrated one

Detail of the leds:

  • The potenciometro R4 fits the threshold of intensity that comes to the leds.
  • The potenciometro R6 is the manager of the calibration of the checker.

Finished assembly of the checker of batteries

3.-Calibración of the checker:

There is taken a pack of batteries of 4.8v and with the polímetro the tension is verified in terminals of the battery. In accordance with this tension there looks in the attached table the number of the led that should be burning. Continued the battery gets connected to the checker, being careful with the polarity. With the potenciómetro R6 we will fit until the illuminated led is the one at that we look earlier in the table and that corresponds to the current tension of the battery. Next we put the table for the calibrated one.
LED
VCC (V)
4.51v - 4.60 v #1
4.61v - 4.70 v #2
4.71v - 480 v #3
4.81v - 4.90 v #4
4.91v - 5.00 v #5
5.01v - 5.10 v #6
5.11v - 5.20 v #7
5.21v - 5.30 v #8
5.31v - 5.40 v #9
5.41v - up #10
This table costs us to know that we have tension according to the led that ignites. In spite of the fact that there knows which is that of the limit that we want for our batteries, then it will be enough that it is in a top led and we will know all that loads he has left.

Tinkering School - summer Camp for apender experimenting

Seeing TED'S chat, which for my inspiration is becoming indispensable, I discover Tinkering School, possibly the summer camp that we had liked going to those that we continue and write this blog.

tinkering school

What do they do in Tinkering School?

Since basically, the children, choose projects and during his stay they construct them.

What can be better for a child to do with your own hands a roller coaster and then throw you for her? Few things, the truth ;-)

to construct a roller coaster

Certainly this roller coaster was constructed by 7-year-old children


All this is a work of Gever Tulley, which as he mentions that there is consturido the campamente than to the one that he had liked going.

Here the children and adolescents use all kinds of hardware and gadgetry; of considered dangerous for them.

children using hardware

If you want to see more project images here you have the gallery of Tinkering School

The point of view of Gever Tulley on the education and development of the children, you can see it in another conference TED, in that he speaks about 5 dangerous things that our children should do. Here it includes.

  • To play with fire
  • To take razor
  • To dismantle devices
  • To throw objects

These ideas I already consider them to be a little more controversial.

The conference: "Gever Tulley teaches life lessons across experimenting"

What does all this look like to you?

Introduction to the electrical model airplane making. Part 9

Constructing IKKARO 001.


I hope that you should have constructed some plane of indicated in the previous post. They are simple and of easy flight. As I commented previously, the target is to construct experimental devices with aptitude to keep on doing even more experiments with them, to be in consonance with the spirit of this web.

I have the prototype IKKARO001 practically built, my intention was to prove it before to begin showing the tutor of his construction, but good, I trust that insuperable problems do not arise.

I had liked using also only materials of easy access, but in the end I could not have done without the deprón. Some other solutions as for if they are more original.

Next and in successive post, I will be showing the construction of the different parts.

Before beginning, I want to warn that the things do not have to be done as I show them, want that this alone is a guide.

What I claim is that you squeeze your creativity and your innovation capacity, using the resources that each one has to hand, and learn to combine the different materials, looking for your own solutions. Like that it is as really it is learned.

The fuselage.

The fuselage is the central part of the plane. The body.

For the fuselage I mentioned already that he was trying to use aluminum. I located in a supermarket a level of material saying that it was promising. It was costing 1 euro, so I bought two units. The Chinese purify so much the material, which instead of aluminum looks like a role. Villain if we want to use it in a work, but ideal to use it in our plane.

photo of two levels.

These levels have a section in the shape of beam, also it is perfectly valid, and enclosed better, if you find at good price one with rectangular section.

In the attached plane there is the form in which it is necessary to cut it. In next post, I will complete the plane with more details. A unit is one centimeter.

To cut it two things can be done, use a saw for metal or use a retractable chopper, doing marked in the surface and taking advantage of the properties of the aluminum, to double it several times for the mark and to break it thanks to the asperity that we provoke. This operation is dangerous, ask for help and use gloves. To use the cutters, always the chopper to the minimum, blocked and cutting with the auxiliary hand behind where it goes the cut, like that it cuts ham or sharpens a pencil with razor.

Also it is possible to cut with shears, but it is necessary to go been careful not to deform it.

(in this photo it would be necessary to see my another hand as the safety norms, but I have it in the camera).

Only to mention that the profile of the level, once we take the plastic ones from him, weighs 52 grams, but he can support a force between his 2 Kilograms ends without distortion, as they show the following photos.

Following the attached plane also you can realize the surfaces of the tail, the horizontal stabilizer and the vertical one. to give them it is possible to use expensive double adhesive tape or specific glue. I have done them with depron of 5 mm, because I was the rest of a packing, they can be done in deprón of 3 mm. or with some feeding salver, already ue are small surfaces. In the following post, we will realize also the surfaces of control and important thing, the flexible union.

Not if I have already commented on it earlier, but they do not cost all the glues to stick depron and the rest of polystyrenes. DO A TEST EARLIER:

Quantum processor (I)

To answer the question about the quantum processor, I will explain first the Idea of the Quantum Computing:

It was in the 70s and at the beginning of the 80 in which there was proposed the idea of using the quantum properties of the matter at subatomic level to process information at very top speeds that the binary computers; For it there proposed a theorist (in that one of that time) information unit to herself, the qubit, which would come to be the quantum counterpart of now very well-known bit.

Fundamentally, a bit, it can only take the values zero and one, minentras a qubit can take different values inside the status (0,1), in addition to being able to have several states simultaneously; Allowing to realize more complex calculations and much more rapid than the binary computers.

Between the problems that the quantum computing find the limitations of the hardware and some of the same quantum properties that try to take advantage. Nevertheless, nowadays this one has managed to construct herself some models of quantum processor, slowly, technology has gone developing since in 2007 the company candiense D-Wave Systems announced having developed the first quantum computer; that turned out to be really a "hybrid", a digital computer, which 'was using quantum technology to solve some problems'.

The first quantum processor, of the solid, programmable state it developed in the university of yale in 2009 (or at least in this year Nature published it) by Robert Schoelkopf.

I leave them some of linkage:

Like cutting crystal bottles in 30 seconds

After seeing that there are the people to whom him the skills do not work to cut glass or crystal that we saw in Ikkaro, we left a new skill to cut of clean form the crystal bottles.

But anyway it is based also on the changes of temperature on the crystal.

It consists of marking the crystal with a widia and then of throwing cold and warm water alternatively, until it sets off.

You can see it clearly in the following video realized by Green Power Science

I hope that it is if that you works ;-)

Introduction to the electrical model airplane making. Part 10

CONSTRUCTING IKKARO 001, STABILIZER AND RUDDER.

Homage to tecob, (obsolete Technology), Broadcasting station of radiocontrol of 1937. (POPULAR MECHANICS). Almost portable broadcasting station.

THE TAIL.

Continuing with the construction, we are going now to show how the pieces of the tail are realized.

The staff of the tail is printed on real size. The role stands out and they are placed on the depron iron, are marked in the iron and it stands out with a cutter, helped by a metallic rule.

Next, once we have the pieces of the tail and the corresponding mobile surfaces, we are going to realize the flexible union.

so that it turns without problems the rudder and the horizontal stabilizer, we are going to realize a pair of rebajes to leave in wedge the contact side between the fixed surface and mobile. In the following photo the process appears and him the result.

Now we are going to realize the union of the fixed part and mobile with two methods. The two are valid, everything depends on the materials which you have. I have used a method for the vertical one and other for the horizontal one, so that you see the two.

Method 1.

Adhesive tape countergiven in two stretches. (this name I have invented it to myself right now).

When the hinges were done of cloth, two strips were standing out and they were making pass at the top and for below in alternative stretches, and were sticking with wooden tail.

To do this with adhesive tape, they prepare a few pieces for themselves and adhere if in a central stretch for the side of the adhesive.

next they are mounted as in the photo.

The resultant union is very effective like hinge, since the mobile surface always remains at the same distance of the fixed surface. If also you use adhesive tape with reinforcements of fibre of vidro like that of the photo, the result is a very trustworthy union.

The method 2 is simply to place a piece of transparent fixo or white seal or of the color that queráis longitudinally in the union of two surfaces, for both faces.

The tape is necessary to put it with the surface turned how in the photo, to allow the later movements.

This method has the disadvantage of which the surfaces tend to separate and which is necessary to check it occasionally do not be going to break.

It is sure that there will exist some other methods of union, miscellany of two previous ones. Do experiments!!.

FIXATION TO THE FUSELAGE OF THE STABILIZERS.

To give the horizontal stabilizer in the aluminum fuselage, we are going to use expensive double tape, as the following photo shows.

To place the vertical stabilizer, we will make use of the form of T invested that presents the fuselage in the tail, and will do a central incision to him in the low part of the vertical rudder, and will fix it in the fuselage, fixing it with a little of glue (read the above mentioned on the glues in the previous post).

Here we have the mounted tail.

AND THE SAFETY ALWAYS.

To use the cutters, always the chopper to the minimum requierido, blocked and cutting with the auxiliary hand behind where it goes the cut, like that it cuts ham or sharpens a pencil with razor.

Always use gloves of protection and goggles.

If you are going to work with glues ventilate well the work area, or do it in location. On tod if lasinstrucciones they come in Chinese and you do not know the language or if they come in Spanish and like that he recommends it. Also use gloves adapted in these cases.
