Electronic Designer (EKON-02 vs Expert)

As they talked with a work colleague about electronic designers, it turned out that Ekon-02 was collecting dust on his shelves. In my childhood, there was no such happiness, and I really wanted my son to have some kind of analog Econ-02.An electronic designer of the Soviet type, the development of the All-Russia Scientific Research Institute "Electro-standard", cost this happiness 14 rubles of Soviet money. I was very interested in the prospect of at least doing something similar on the model. Radio components are fixed on the plane, conventional wiring is used for the connection, the contacts of the radio parts inside the case are inserted into the springs, so all the contacts are brought to the surface with the help of the springs. It is necessary to say that the springs are rather dense, the coils touch each other, if the spring is stretched and the wire is inserted between the coils, the spring will tightly clamp the wire, there will be a fairly stable connection between the radio parts without soldering.Resistors, capacitors, diodes, transistors can be bought in the store. And some components can be made by hand, for example, a button or a coil. At first I thought that it would be difficult to get a photoresistor, but this turned out to be wrong. It’s nice to do it yourself, but if you buy it in a store it’s much better. Search on the Internet did not give anything, of course, I found electronic designers in online stores, but I did not like them, besides the price was high. The presence of the Soviet designer Econ in the workplace for two weeks did not pass by the attention of colleagues, someone remembered his happy childhood and it was this designer, someone with children's delight rejoiced at the sounds of the siren just assembled on the designer circuit, but most importantly they gave me a tip where a similar designer is sold in my city. Unlike ekon, which is designed for children of senior school age, the electronic designer "Expert" for children from 5 to 55 years old, the Chinese are kidding. Produced in China under the patronage of the Russian company, the usual things. It was a bit disheartening that the three parts are a black box, i.e. what's inside is not clear what kind of chips for sounds. Although it would be difficult to interest the five-year-old son to make a chip playing Happy birthday to you, in principle, it will grow interested in what's inside.Do not count for advertising, but my five-year plan was happy when we yesterday collected the imitator of sounds from star wars.
