  • Hopeok Code Studio Own analog of the cursor with AI

    AI & Machine Learning
    Hopeok Code Studio Own analog of the cursor with AI — example of freelancer's portfolio work in category AI & Machine Learning
    This is a closed development, my own version of the cursor that I wrote for myself; it has no limitations that the cursor has.

  • Professional AI Voiceover

    Audio Processing
    Studio quality sound for your videos, YouTube channels, or audiobooks in Ukrainian. Correct accents, natural pauses, and perfect audio clarity (WAV).

  • Dual-channel PWM generator for single-phase motor (STM32)

    Embedded Systems & Microcontrollers
    based on the STM32F411 microcontroller.

    This solution is specifically designed for controlling single-phase BLDC motors and can also be adapted for other electronic devices where high signal synchronization accuracy is required.

    … Technical specifications and capabilities: Frequency range: from 1 Hz to 1000 Hz (stable operation even at very low speeds). Control: Three potentiometers for full parameter control. Adjustment:

    Change of duty cycle.

    Setting phase shift between channels.

    Adjustment of delay relative to the Hall sensor. Stability: Signals remain symmetrical and clear across the entire frequency range.

    How to obtain this controller? Want to use this solution in your project right now? Support the channel's development with a donation of 1000 UAH, and I will send you a ready STM32 board with a secure firmware installed!

  • Digital magnetometer on STM32F407

    Embedded Systems & Microcontrollers
    Ready project (Source Code + Python GUI scanner)
    This project is based on the popular debugging board STM32F407G-DISC1. It is perfect for developers, students, and enthusiasts who need a stable foundation for working with analog sensors and high-speed data transmission to a computer.

  • Professional Data Logger: STM32G4 & INA226 STM32 Python

    Embedded Systems & Microcontrollers
    STM32 + Python: How I Overclocked the Logger to 1000Hz (Real-Time GUI) In this video, I show how to achieve professional measurement accuracy (140µs) using the Nucleo-G474RE and custom software in Python. No delays — just real-time! Technical details:

    Hardware: STM32 Nucleo-G474RE

    … Sensors: 6x INA226 (Turbo Mode), HX711 (Scales), Tachometer.

    Software: Python (Multithreading GUI) + CSV Export + FTP Cloud.
