  • Control system of granulation

    Embedded systems and microcontrollers
    The creation of the ASU of the granulation plant (mast extraction plant). Description of the software for the Siemens Simatic S7-400 controller and the implementation of the SCADA visualization system (WinCC).
  • Apparatus for Wending Automatic

    Embedded systems and microcontrollers
    The system reads the RFID card, sends a PUT request to the server( via media or WiFi), with a positive response on the balance connects with the automatic controller (MDB) and gives the command to the vacation. receiving feedback - manages to the server data on the operation...
  • Equipment for the City Questa

    Embedded systems and microcontrollers
    The device is programmed and memorizes the coordinates of 6 points on the locations (GPS module), then when enabled is no longer in the programming mode, but in the state - indicates the indication from 4 LEDs the direction of the movement in parallel to each of the recorded points in the memory (work synchronically GPS modules and magnetometers ("digital compass")). When players enter the right point, the device disable the indication of the direction, includes the record of the voice clue, awaits the password input (keyboard) and with the right input - leads players to the next point.
  • System of Automated Drying

    Embedded systems and microcontrollers
    The system is controlled both locally (click on the controller body) and remotely from any Android device (from the application). In the controller is installed a GSM module, for connection with the server, through which it is the exchange of data with the application. There is the possibility to choose the amount of the irrigation zones, the time of irrigation of each zone in the cycle until the moment when the moisture of the soil reaches the given level. The humidity is measured by the sensors of the emcostic type.
  • The flexible system of control

    Embedded systems and microcontrollers
    Control of the machine through a touchscreen display. The ability to ask: the number of iterations, the angles and their quantity in each iteration, the angle of the stretch and so on. The number of iterations is traced and displayed in the separate menu, the passes are stored in the energy-dependent memory. The drive of the engine is implemented on the step engine.

Good day .Unfortunately, they are forced to close the order and leave a negative feedback, as the project was not and will not be completed by this executor.Chronology of events:
On April 18, 2023 the project was initiated.Duration of work: 2 calendar months.The cost of the work: 80 thousand SEK (the commission for "Safe" is paid by the customer).Due to the impossibility of entering 80 thousand by one payment, the project was formally divided into 2 parts by 40 thousand SEK.- On 1 June, the executive informed the customer that "can't guarantee that it will be invested (in time)", as there are "a lot of nuances",
which he could not foresee at the planning stage.On June 18, the executive sent a video with a demonstration of the work of the system.On the question asked on June 19, whether the system was checked with laser rather than LEDs (but we have the "Laser" labyrinth project), the answer was: "Welcome.I didn’t buy the laser and I didn’t have them in the stock, I check on the diodes.”We were contacted via telegram: there was a need to discuss the situation by voice, not by text.The executive warned us that despite the difficulties he will be able to complete the project.I apologized for the broken deadlines.On 25 August, nine weeks after the deal was agreed at the very beginning of the deedline, the executive announced that the project was ready and that he sent it to the customer by mail.On August 29 the mail was received by the customer.- September 12 after the system was collected in accordance with the scheme sent by the executive.Unfortunately, it didn’t work, about which the customer informed the executor.For the next 10 days, the customer was in constant contact with the executive, trying to solve the problem.On 22 September, the customer addressed the executive through the platform with a number of specific questions to which he did not receive answers.During the next 10 weeks, numerous attempts were made to force the system to work, which cost the customer funds (payment of the work of specialists) and time (according to the agreement, the system should have been working for more than 5 months).These attempts did not lead to the system's work.The end:
- 33 weeks later (with a period of 8 weeks) the customer has not yet received the work system,
The amount of funds (basic fee, additional purchases, the payment of the work of the specialists) and time (lost profit) are spent in order to come to understanding with the executor.The executive did not perform his work neither in the period nor in 25 weeks after the deadline.The customer requires the full refund of the funds entered in the seafood.

Спасибо очень огромное Сергею, очень профессионально отнёсся к Моему проекту за что отдельное Спасибо. Были проблемы не со стыковкой железа, человек переписал программу под мой дисплей и очень внимательно меня выслушал, что требовалось сделать по моему описанию над проектом. Заказ был выполнен в оговорённые сроки еще порадовала цена в итоге Я получил то что хотел за разумные деньги что не может не радовать. Если будут еще проекты буду всегда обращаться к Сергею, надеюсь это мой не последний проект. В итоге Я получил то что хотел.
