How to make an electronic designer. We collect electronic circuits
September 3, 2014 at 03:56 pmHow to cross the Connoisseur constructor and Arduino with your own hands
- DIY or DIY
I will not tell you what it is and how to write sketches.
I will not explain which end to hold the soldering iron.
I will not state the arguments for and against the existence of an electronic designer on clothes buttons.
I will tell you a story about the successful experience of crossing the Connoisseur and Arduino in a single household.
background
One evening, we collect with the child a diagram from the Connoisseur constructor. Turn on. I smell burnt plastic. Turn off. I analyze the circuit and see that in my edition of the circuits of the esteemed A.A. Bakhmetyev, the transistor unsuccessfully modulates the chemical voltage source, giving out its sincere indignation at the temperature.The transistor died as a result. And I replaced it again:
To do this, I had to break off the white bottom cover, but valuable experience was gained in parsing the details of the designer:
The young experimenter did not stop there and soon announced: “Houston, we have a problem: block 23 failure”:
This is where the experience of parsing a block with a transistor came in handy. Inside block 23, there are two drop-shaped microcircuits marked TAIKONG-1 and TAIKONG-2, as well as an S9012 transistor. I replaced the transistor, although it was serviceable, but the unit did not come to life. Since I didn't have an electron microscope, I had to google a lot. Apparently, this module was supposed to make the sounds "Piu-Piu-Piu" and "Thousand-Thousand-Thousand" depending on which leg was on the ground. If both legs were on the ground, the combination "Piu-Tysch-Piu-Tysch" sounded.
The next evening, block 21 died. There are two transistors inside the block (already familiar S8050 and S9012). The replacement does nothing. The marking on the CLZSD1 board did not succumb to Google. Interestingly, there is only one melody, but you can set its duration through the resistance between the legs.
As time went. Block 22 died. Inside the S8050 transistor and a droplet microcircuit. The board is labeled CL9561. Replacing the transistor did not revive the block. Google has shown that this board is widely used in children's toys (automatic machines, cars) and in children's alarms. Able to make the sounds of fire and police sirens, ambulance and machine gun fire, again, depending on which foot is on the ground. That's right: two legs - four audio tracks.
Microchip analogs in the DIP and MSOP LM4871 package, or KD9561 boards cost from $0.30 in a commercial lot or from $3 from 5 pieces. I didn’t want to pay $15 for sound effects, especially on the evening of a hard day when you really want silence, and I safely forgot.
Summary: repairing blocks is impractical:
- economically;
- there are no guarantees that they will not fail on their own, or with the help of a young designer due to lack of protection and incorrect circuits;
- the element of novelty disappears and interest in design falls.
Theoretical research
I'm not an arduinist, but the idea of \u200b\u200bcrossing the Arduino and the Connoisseur constructor was in the air. If the child has mastered the constructor, let him continue playing with Arduino, especially since there is Scratch for Arduino. It is difficult for an adult to move from a leg step of 2.8cm to 2.5mm, and even more so for a child. Therefore, it was decided: we use the standard ones made by "Expert". We go to the store for clothes buttons and get prices of $ 1 per button. I didn't expect this. For $20, you can buy an entry-level "Expert".Once I was fiddling with the Arduino Pro Mini 5V board in my hands. Suitable sizes. The power supply is suitable for the "Expert" (4.8..6V = four batteries / accumulator). The price is reasonable around $3. I don’t trust the child to upload sketches until I trust them. Here are just too many inputs / outputs, and the choice of digital / analog adds degrees of freedom. How can all this be divided into three legs of a standard block (two for power and ground)?
- Idea times: we output three free clothes buttons of the block to the connectors. If necessary, the connector will be dressed by an adult on the correct Arduino pin.
- Idea two: the Arduino configuration can be set by setting the jumpers on the legs and interrogating them when starting the sketch. Choosing what Arduino will pretend to be: a traffic light, a music box, a burglar alarm, etc.
Implementation
We take a block. We understand carefully. First, gently tap the block around the perimeter with a hammer, in the hope that the fragile glue will crack. Next, we drive a thin knife (or rather a scalpel) between the block and the lid. Gently shake and loosen the glue around the perimeter. After a couple of minutes of careful manipulation, the white protective cover is removed and we can see the insides of the block.
Ruthlessly soldering the fee. We probably won't need it again.
We cut the cover of the block with a hacksaw or a dremel.
Slightly (literally by a millimeter) we increase the hole in length. The Arduino Pro Mini must not fit through the hole. We solder the pins. I was too lazy to think, so I soldered all the pins. Having a debugged sketch, you can solder only what you need, or do without pins at all. The skirted pins should fit through the hole (what's the other name for that black plastic ruler that holds the pins together?)
We solder food. Based on the standard scheme for the Connoisseur: the top will be "+" (RAW), and the bottom "-" (GND).
I could not resist - I collected the first scheme. Traditionally, it blinked with a built-in LED.
We wash the board and drill holes for the wires. Keep in mind that the parts of the designer being installed can block the holes and interfere with our wires, so it's better to step back an additional 2..3 mm from the center of the button.
Uploading the traffic light sketch. Putting together a new scheme. We hook the wires from the buttons to the corresponding legs of the atmega. There are only two LEDs in the Connoisseur's kit, so I soldered a white-lunar LED (there was no other at hand) into the base from a faulty light bulb. And enjoy!
The block can be stored in a standard designer box, you just need to pull the wires out of the pins. (Or down with pins, then you can not pull out the wires).
It would be nice to put protection, 20 ohms for each of the three legs of the block, and provide for a reverse polarity. But the $3 Arduino replacement price is way below my laziness.
The new building block "Znatok" revived the child's interest in electronics. What is the name of the new block now?
Amendment dated 09/04/14.
The support pin of the plastic base of the circuit board rests against the Arduino. Therefore, the board should be mounted above block, and not from below, as described earlier. It was this version that went into production:
No matter how changeable and unpredictable the modern world is, it is still considered useful and even honorable for a man to be well versed in various mechanisms, to be able to repair and even assemble them. At the same time, using improvised means, in our time it is easier to master complex programming than to assemble even elementary electrical mechanisms - almost no attention is paid to the latter topic. Fortunately, not everyone is so indifferent to this problem, so there are special designers of the Znatok brand.
What's the brand?
Probably, without exception, all representatives of the older generation still remember Andrei Bakhmetyev, the host of the previously popular TV show Crazy Hands. Thanks to this man, surprised viewers learned that almost anything can be assembled from improvised means and with one's own hands, and it is possible that many modern craftsmen grew up on his programs.
Today this program no longer exists - in particular, because its permanent host has become one of the co-owners and developers of the Znatok Plus company.
Probably, there will be no new information that learning any things, and especially rather difficult ones, should be started as early as childhood. By properly disguising learning as a game, you can instill in your child an almost intuitive understanding of the laws of physics and electricity, in particular, teach him to assemble any mechanisms. Usually such training is impossible without soldering, which is both dangerous and not very interesting for a child, so Bakhmetiev came up with a worthy solution to the problem - he began to produce special constructors that allow you to assemble a variety of mechanisms, including complex ones, without soldering.
A typical set necessarily includes wiring diagrams, wires, various switches and LEDs, radio control modules, speakers and much more, all of which can be connected in a plug-in way.
The set, of course, also includes a user manual that helps the kid quickly navigate the essence of the assembly.
The history of the company so far has only four years, but there are already some successes. Since the products are positioned as those intended for home and school, special educational institutions often act as buyers, and almost two dozen of them have even become regular customers. In 2017, the company sold several thousand of these construction toys, despite the fact that they are still not a popular gift for a child, so we can safely say that the company's future prospects are very bright.
Why should you buy such a designer?
If we talk about the reasons why sets of this type are becoming more and more active, there are several obvious reasons that encourage adults to buy such a gift for a child.
- For the first time, learning physics becomes really interesting! Instead of boring abstract stories, a child can see with his own eyes how this or that mechanism works, and even assemble a working model of this or that electrical appliance, which will become a real reason for pride. Obviously, with such a set, the child will not have to be specially forced to study - children's interest is guaranteed even without it.
- The main developer over the years of work on television has earned the unquestioned authority of a knowledgeable person, and he, of course, did not forget about safety and quality. Spare parts are produced from safe materials, which are also distinguished by high strength and durability.
- You can start teaching your child the basics of electrical engineering from early childhood, because there is nothing difficult in working with such a set. Soldering is not required here, because all parts are connected by plugs and bolts, the process is completely safe. The instruction is provided with a detailed and colorful description of the whole process, the kid does not have to reinvent the wheel to assemble something complicated on his own.
- In addition to actually mastering the skills of working with electrical engineering, in the process of working with "Connoisseur" Children also develop their own mindfulness and accuracy. For all its simplicity, the set is still not elementary - you need to sit on it for a bit in order to achieve decent results. However, the same result is so close that the child does not lose motivation in the assembly process.
- It is noted that the most complex varieties of the Connoisseur constructor can be interesting even for adults, if their professional activity is not directly related to the assembly of electronics. Since such an activity is equally interesting for both kids and adults, parents have an additional opportunity to spend more time with their children, improving the microclimate in the house.
In addition, such a set will be a great opportunity for every father to show his son that his dad is really cool.
Perhaps the only drawback of such a gift may lie in the wrong choice of set. If the child is still too young to understand the ongoing processes, then he is unlikely to be interested in the assembly. In addition, some children are so far from electronics in principle that they will not be interested in it even in a game performance.
First steps in electronics
If the kid is still very far from the first physics lessons, but he shows interest in technology, you can immediately try to play on his interest by buying him the most childish of all sets dedicated to the development of electronics. Such sets are divided into two types: the first one contains two different sets of 15 schemes, the second one consists of 34 schemes.
Even small sets of 15 circuits already make it possible to assemble a fully working, albeit primitive design - for example, a flashlight or a fan, to conduct experiments with a magnet.
After that, the child will not become a design genius, but will definitely master the general principles of electrical appliances. After that, you can proceed to a set with 34 schemes, which will allow the baby to assemble a full-fledged radio receiver with light and music, from which the child should be delighted.
The cost of small sets for beginners starts from a thousand rubles, a set with 34 patterns can cost parents more than 2 thousand rubles. It should be noted that none of the assembled mechanisms will work without batteries, so you should get ready to buy them in large quantities for a carried away kid.
Alternative energy sources
If you still don’t want to spend money on batteries, but there is an idea to show your child how electrical appliances can function without an outlet, you should buy him a kit called “Alternative Energy”. The simpler version of this construction toy includes 50 different projects that give your child a general idea of how to use solar and wind energy, as well as how to use mechanical energy for their own needs. The price of such a set will be up to 4 thousand rubles.
However, the above set is only a simplified version of another constructor, which includes 126 schemes at once. The extended version additionally introduces the use of water and hydrogen energy, significantly expanding the list of available sources of electricity in the understanding of a small owner.
Interestingly, for all its “alternativeness”, such a kit needs ordinary batteries, but they are needed, in particular, for distilling water, which does not flow in the kit itself, as it would be in nature. With an increased number of parts and projects, the cost of the set also increases, exceeding 5 thousand rubles.
Complex sets
For those parents who are confident in their child's stable interest in physics and electronics, an extended set of 180 circuits and a complex one of 320 should be of interest. In many ways, they represent somewhat supplemented sets described above, but they also have quite a lot of completely new details. . At the same time, the abundance of projects should not be intimidating - such designers are still considered more like gaming than serious teaching aids.
It should be noted that in the set with 320 circuits, all the circuits from the "truncated" set are repeated, so their sequential acquisition does not look quite logical.
The smaller of the two sets allows you to assemble such unusual mechanisms as a flying propeller or a light and sound doorbell, and even a burglar alarm. It will be possible to control the assembled mechanisms in several different ways, using a variety of power sources and adjustment methods. The price of such a gift is almost 3 thousand rubles.
The expansion to 320 circuits is due to the fact that radio components and the ability to remotely control mechanisms are included in a more advanced set. A bonus to such an assembly will be a telegraph and a megaphone, a metronome and a radio receiver made by hand. The cost, of course, will be higher - it reaches 4.5 thousand rubles.
Special Sets
In some designers, the developers of "Znatok" pursued the goal of visually showing the kid this or that branch of electrical engineering. These sets include "Voice Magic" and "Super Meter". The cost of each of these sets is almost 7 thousand rubles.
As the name suggests, Voice Magic is all about voice control. The creators focus their attention on the fact that voice control is the technology of the future, which has already become quite firmly established in our homes, so it’s worth understanding it. Accordingly, all or almost all mechanisms assembled from this set allow voice control.
"Super Meter" teaches you how to work with measuring instruments. Unless the simplest mechanisms do not use them at all, but the same car is literally crammed with various measuring equipment, and the functionality of the model as a whole largely depends on the correct installation of it. The level of lighting and noise, temperature and electrical voltage in the network - these are just a small list of indicators that can be measured with such a set.
Homemade toys based on electronics
A radio-controlled car is the dream of any boy, but most varieties of such a toy cannot even do half of what the Connoisseur assembled from the constructor can. Additional pride, of course, will be the fact that it is assembled independently, albeit from finished parts. The key feature of such kits is the absence of numerous schemes for assembly - it will be possible to assemble only one model, but what kind!
These "Expert" kits include the radio-controlled all-terrain vehicle "Leader" and the so-called "Smart Machine". If the “Leader” is actually an ordinary radio-controlled car, which differs only in the ability to turn on the headlights, then the “Smart Car” even allows for such advanced options as voice control and signaling. Interestingly, the last set can go even without external control, accurately avoiding obstacles that arise on the way, but both options cost the same - 7 thousand rubles each.
999 schemes
The manufacturer classified only one of his kits as a medium complexity category, but in fact, absolutely all electrical engineering is shown here in a section. This is a real #1 superset that has even won awards at various international competitions. The usual instructions are not enough for him, so he contains two books on physics at once, showing the connection of the school curriculum to real life. Reviews indicate that kids with relevant interests experience great pleasure from working with such a set, but it will also give adults a lot of food for thought. On the example of such a designer, you can even consider the work of a lie detector, and the composition includes a huge number of components of different types.
The idea of creating an electronic construction set has been on my mind for a long time. As a child, I had an EKON-1 constructor and I wanted to create something similar, but at a modern level. The Connoisseur rules the ball on the market, there are also examples of modular constructors abroad, but the price and exchange rate are not pleasing to the eye.
On the other hand, there were interesting developments in the USSR (one of them still lives in Germany and is being produced):
I also wanted something “warm” in materials, such as wood. In 2014, within the framework of the PROSTOROBOT project, the idea of electronic cubes was born, which in 2015 even received a prize from AIDT for the idea at one of the qualifying stages of the Startup Tour.
It was also during this time that I came up with the logic board game "Circuit", which allowed "electrical circuits" to be played. The game can be freely downloaded and printed from the link.
Time passed. The cubes had to be put aside, since the price of magnets of the required power made them quite expensive. The game "Chain" waited for its turn to be finalized.
In 2016, I decided to return to the project and "got" the cubes. The first idea was to use the same cubes, but make fasteners like spring contacts and glue a cardboard box with cells, on the walls of which the contacts would be located:
The design turned out to be cumbersome, and due to the low rigidity of the walls, the cubes did not provide the desired quality of contact.
Engineering thought moved on. A small digression on the choice of material. Can you reasonably say why I did not use 3D printing or laser cutting? The answer is simple - I don’t have a 3D printer (more precisely, there is nowhere to put it in the apartment), and the nearest sane cutting in terms of price and quality is 500 kilometers from my city. Even finding thin plywood turned out to be an unrealistic quest, not to mention a special model one. Plus, I have long wanted to try the material familiar to fans of board games - cardboard.
The second option was to apply the method that I had already used earlier when designing Scratchduino - that is, 2.5 modeling of the constructor blocks themselves and magnets for fastening. This method did not require powerful expensive magnets, and at home I had a supply of cylindrical 5 mm magnets of different heights (2 and 3 mm).
It was also decided to first make a “physical” analogue of the board game “Chain”, since it required a field only 4x4, and then after collecting all the “bumps”, make the assembly field larger (at least 4x6, but better 6x8).
There was one more question - from what to make contacts. The ideal is a copper strip. The problem of the ideal is where to get it. Also, copper is non-magnetic and it would be necessary to put magnets on the field and on the blocks. Taking into account the fact that more powerful magnets would be needed to place them under the contacts (and this means both money and time for shipment), the search for a suitable material continued. And the eye fell on the staples for the stapler. The houses had staples of various sizes, they were steel (that is, they conducted current and were magnetized) and there were a lot of them.
As a result, the list of necessary components was determined - staples for stapler No. 35 (26/6 1 pack), neodymium magnets C-5x2-N35 and C-5x3-N35 with nickel coating (conductive), cardboard (microcorrugated cardboard left over from packages from - under photos and boxes), wire, solder, LED, resistor, microbulb, diode and button. To glue the parts, it was decided to use PVA glue, and an ordinary hole punch came up to punch holes for the magnets.
The materials were determined, the dimensions too (cell 40x40 mm, block 38x38 mm) and the direct process began.
The field is a sheet of cardboard, marked into squares 40x40 mm, the side faces of which are “stapled” in the center with a block of staples.
I took the staples the same as for blocks-cubes, but immediately made the first mistake. I did not see that the staples were covered with a non-conductive material on top and therefore had to be protected later. I also tried to tin them (which turned out to be not very high quality) and the size of the brackets should be taken more so as not to depend on the errors in the manufacture of blocks. If you decide to repeat this design, take staples about 20 mm wide and make a block 1 cm wide.
The staples were inserted into the slots in the cardboard and bent from the back. In the photo, the side wires are needed to "imitate" the common bus of the board game "Chain" and in the final version of the designer they will be replaced by blocks.
So, as a result of this painstaking work, we get a field with contact pads, to which our contact magnets are well magnetized.
Now it was necessary to make the blocks themselves with conductors and radio components. The problem was also that in the board game there were elements with a cross-shaped intersection and crossing conductors, and it was impossible to ensure the contact of all 4 magnets (remember how many points the plane passes through). Therefore, it was decided to abandon such blocks and make the maximum of T-shaped elements. For crossing elements, I plan to use special wire bridges in the future.
The block itself consists of three squares of cardboard measuring 38x38 mm. On average, holes are made for magnets and slots for brackets. On top of it, a second square is glued to the PVA glue only with slots for staples. After that, a small magnet 5x2 mm is installed in the hole, closed from above with a block of brackets that are bent on the other side. Radio components or conductors are soldered to them. On the other hand, we put magnets 5x3 mm and glue a square with holes. Due to the fact that the magnets "stick" to the magnets under the brackets, they hold very tightly and do not remain on the field.
Thus, we produce blanks with two and three magnetic platforms. Then solder the conductors or radio components.
We glue cardboard strips on top (two or three layers depending on the height of the parts) and close everything with a cardboard “lid”, on which we draw a designation with a marker (straight conductor, angular, T-shaped or radio element).
As a result, we got such a field and a set of details. I did not make the battery in the form of a block (although there is an idea to use a 5 V tablet in the future), but I made an element with two wires to which 3 batteries are connected.
During testing, it turned out that the bulb did not light up if there was an LED or a resistor in the circuit, and the LED could not be used without resistance (the smell of burnt plastic clearly showed this). Therefore, to simulate the gameplay, it was decided to assemble a “signal” circuit from another LED and a resistor on a breadboard, and simplify the game a little, leaving only one LED that needs to be “lit” to win. This turned out to be not critical, and this option was even more interesting, as it allowed changing the starting conditions of the game. The Circuit game itself in the tabletop version will also be redesigned and moved to a larger board, with multiple lamps and LEDs and different starting positions.
Cards were also prepared for the game, by drawing which the player understands which element he can use. Below is the final photo of the radio constructor game, as well as the game process.
Electronic designers are well known to many from Soviet times: it was very interesting to assemble circuits and watch how the device starts to really work! Today, such sets are also on sale, and they have become even better and more interesting.
A set of electronic blocks and connections that allows you to design electrical circuits without soldering.
The manufacturer of these kits today: Connoisseur.
In the series there are different electronic designers, differ in the number of circuits.
The largest set is 999 schemes + school.
The Znatok electronic construction kit has been released in a new version "For educational institutions". This is 21 practical lessons for the school and many schemes for additional classes. And for the house such a set is a real dream!
The main task of practical classes is to show the connection between the school curriculum and the modern life around us. That is why the constructor contains elements that are present in almost all the technology around us - computers, phones, cars, photo and video cameras, televisions, musical equipment, etc.
Practical classes are consistent with the existing school curriculum and physics textbooks for grades 8, 9, 10 and 11. But since education is becoming more and more differentiated, the tasks are not divided into classes, but into 3 groups of different levels of complexity:
Blue - entry level;
Green - medium level;
Red - the level is above average.
A practical lesson contains one or more tasks. The teacher, depending on the level of preparedness and career guidance of students, may require the completion of all tasks or only part of them.
The proposed practical tasks can be performed when studying the following topics and sections: Mechanical oscillations and waves. Sound, Fundamentals of electronics, Integrated circuits, Digital technology. Logic circuits, Electrical phenomena. Direct current, Electromagnetic phenomena, Electrostatics, Electric current in various environments. semiconductor components.
The specified product was highly appreciated by specialists in the field of electronics, and was also tested in many Russian schools and institutions working with children.
There is a smaller set, for example, 180 schemes:
Very good designer!
From the reviews:
I bought a similar one for my son when he was 5 years old and, frankly, I was worried - is it not too early, whether the child will be able to understand what it is, what is the point of constructing all kinds of schemes and, most importantly, whether he will be interested.
At first, my son and I assembled simple circuits together, and most of all I was pleased that already on the third day he himself (of course, using the instructions attached to the designer) was able to assemble a relatively complex device without anyone's help and was sincerely happy about it.
So, despite the apparent complexity and the use of "dark forces of electricity" in the constructor, even a small child who has not yet reached school age will be able to figure it out with the help of his parents and subsequently create various schemes that implement various special effects.
What can we say for schoolchildren: they can deal with the schemes themselves, already without the help of their parents, and this one is really very interesting! 
Real magic is manifested with these constructors - several connected elements, and now, under the breath of a breeze, a sound is born, when a person approaches, a light comes on, music is heard from nowhere (with the help of a designer, you can also assemble a simple radio) - so please your children, and at the same time in teach the simplest basics of electrical engineering in a playful way.
Physics in action! The essence of the designer is that you need to assemble electrical circuits according to the schemes, with the correct assembly, either the light bulb lights up, or the fan turns on, or music plays, etc. Moreover, according to one scheme, when making various changes to it, it is possible to achieve, for example, that the propeller from the fan takes off into the air or the light bulb and the LED will flash alternately. For younger kids, this is amazing! For older children - live physics.
The constructor is made with high quality, everything works, the parts are attached perfectly, according to the principle of buttons.
In addition, the Connoisseur releases a series of Magic Tricks with Hmayak Hakobyan for games, electronic sound posters, and much more.
Electronic constructor "Alternative energy sources"
This is also a set from a series.
Environmental protection is a global problem that has no borders and crosses all oceans. The destruction of the environment by industry leads to irreversible consequences for life on the planet.
The constructor allows you to understand the principles of operation of innovative resource-saving technologies.
The electronic designer considers 5 programs on topics: solar energy, wind energy, water energy, hydrogen energy, mechanical energy.
A color book is attached to the designer - a guide for assembling 126 projects.
If you wish, you can come up with new projects yourself and collect them. All elements of this construction kit are compatible with other electronic construction kits of the Znatok series.
Radio-controlled all-terrain vehicle "Leader"
Also from the Connoisseur series.
A new electronic designer for creating a radio-controlled all-terrain vehicle; machines working in the dark, and more than 20 different projects.
Open the box and find: over 30 different model building parts; remote control; all-terrain vehicle body; detailed color instructions; description of more than 20 different projects; special projects for those who have already become the owner of the "Znatok" constructor, as the details of this constructor are compatible with the details of other series.
If you present this set to your child, he will be able to: assemble different cars; control the car with the remote control - make it move forward and backward, left and right; turn on and off headlights, red and blue marker lights; observe the movement of mechanisms in the car; work on many different electronics projects; connect parts and get different sound effects; learn Morse code; see how the machine assembled by him moves in complete darkness; create a machine with two signal volume levels; build your own lighthouse fun to spend time for not only very interesting, but also very informative and useful activity.
With the help of unique schemes, you can create numerous educational projects that are easily described in the instructions. More than 20 projects. A very useful toy and a great gift for a boy.
The electronic designer is a great entertainment for a child, which allows you to combine the game with gaining knowledge about the physical world. Being engaged in the creation of electronic circuits, the child will get acquainted with the world of electronics and will get great pleasure from the gameplay.
The electronic designer is most useful for children. At this time, they receive basic knowledge about electronics, and playing with the designer allows them to deepen. The student has the opportunity to independently create a sound simulator, a voice recorder, or all these radio-electronic devices are contained in the abstract that comes with the designer.
Not only schoolchildren, but also younger children can play with the electronic designer. The fact is that to create an electronic circuit, the parts do not need to be soldered - they are connected using buttons. This allows you to easily and quickly make the desired electronic device. And if you don’t like the result, then the details can be disassembled. And start all over again.
When purchasing an electronic designer, remember that only children over 4 years old can play with it on their own. The construction set contains many small parts that the baby can accidentally swallow. Therefore, if your child has not yet reached the recommended age, then assemble the electronic circuits yourself, and the child will watch with interest all the ongoing manipulations.
In the production of the designer, only environmentally friendly materials are used - non-toxic plastic and metal connecting elements. This ensures that (subject to the rules of operation) the parts of the designer will not emit any harmful chemicals.
Assembly of electronic circuits can be carried out both on the table and on a special plastic platform, which is included in the kit. But, of course, the second option is much more practical and convenient - the finished electronic device can be easily transferred from place to place, due to the fact that all its elements are fixed on a rigid and solid "substrate".
Electronic designers create different manufacturers. In Russia, the electronic designer "Expert" is especially popular. There are many reasons for this. It is noteworthy that the electronic designer can be produced in different variations (the number of schemes varies). Naturally, the more of them, the higher the price, since the kit includes additional parts.
As already mentioned, a high-quality designer comes with detailed instructions in which you can find images of electronic circuits. The number of them depends on the variation of the designer. At the very beginning of the abstract there are schemes, the assembly of which is not particularly difficult - even a preschooler can design them. On subsequent sheets, the complexity of the circuits increases. It is better to start the game with the simplest options.
In general, an electronic designer is a great way to keep your child entertained with an exciting game that will increase their intellectual abilities. In addition, the game with the designer develops fine motor skills of the hands - in the future, when the baby learns to write, this will undoubtedly be beneficial. And for schoolchildren, the designer will facilitate the acquisition of knowledge about electronics and translate this process into a game form.
