Здравствуйте, Андрий. Надеюсь у вас всё хорошо. У нас есть задание для ESP32. Необходимо сделать АР на котором будут DHCP и DNS серверы, и функция маршрутизации пакетов между Wi-Fi Ethernet портами. Эти функции есть в отдельных примерах ESP-IDF, а нам нужно объединить их в одной программе. Сколько времени вам понадобится, чтобы реализовать это и во сколько вы оцениваете эту работу?

Добрый вечер Андрей, я студент электроники и мне нужна помощь с разработкой печатной платы и firmware. Плата должна иметь микрофон чтобы читать частоту звука (0-40khz) и с помощью модуля ESP32 показывать её на телефон через bluetooth. Должна также имеется возможность передачи данных сквозь API.

Здравствуйте, Viacheslav T.! Я обратил внимание на ваш профиль и хотел бы предложить вам свой проект. Есть ESP32 DEVKIT и I2S микрофон. Нужно, чтобы по нажатию кнопки начиналась запись, по второму нажатию останавливалась и файл отправлялся по интернету. Стек технологий на твое усмотрение, но чтобы была возможность получать эти записи по интернету и работала более менее стабильно (а не по локальной сети). Никаких больше специфических требований нет. Можем связаться в телеграмм - @kishovRasul

Hello. It is necessary to translate text from video to English, German, French, Japanese, Chinese. Text from the video with time points attached to the project. Link to the original video Next, the translated text should be recorded in audio files. Professional audio recording and expensive studio is not required. You just need to use a microphone with noise suppression and a native speaker with normal diction. The audio file should be recorded with reference to time points specified with the source text. Or without reference to time points, but then each sentence is written to a separate audio file. The names of the audio files in the second case are "00:08 English", "00:16 English" or "00:08 German", "00:16 German" and so on. ...

...the recording requirements, you will be asked to re-record. This can be very troublesome. Need your special attention. Pay attention: 1. Need a quiet environment, but not an empty room (need to avoid the echo problem in the room). Do not have the sound of electric fans, air conditioners, or outside traffic. Quietness is the most important thing! 2. Do not record with your mouth facing the microphone, you must keep a distance of 15cm,When recording with a mobile could place your phone on your chest or on a table. 3. Need to use APP to record.I will sent you details after you bid. 4. Each person is expected to work for 50 minutes, which needs to be completed on the same day. 5.

...this new platform that relates to and potentially resembles the Girl Power Talk design. We expect the designer to be creative in coming up with a meaningful, memorable, yet clean and understandable design. You can decide how the logo represents the existing Girl Power Talk “butterfly logo”. Similar to how the existing logo uses symbolism with its components of women's faces in the wings and a microphone, the Girl Power X logo needs to showcase how the platform will transform the Girl Power Talk community—and scale it to help unleash the creative energy, heart, and mind of the global youth. Technical Guidelines • The designer has the freedom to think of color schemes. The logo, however, needs to be first created in black and white so that it can be a...
