Some Projects I've Been Working On

Simple CPU Simulation & Visualization

Front View
Front view 		LED Display
LED displays
This was my undergraduate thesis project. I built an ESP32-S3 based RGB LED device for students learning computer science fundamentals. The device simulates a simple CPU called "Maszyna W", visualizing its internal operations in real-time.
  • Connectivity: WiFi-enabled for live integration with a web simulator via WebSockets.
  • Modes: Supports both local and online operation.

Low-Level Image Pixelization Filter

Program UI 		LED Display
Output example
This project implements a pixelization algorithm that averages blocks of pixels to create a pixelated effect.

  • Algorithm Implementation: Three dynamic libraries written in C++, x86 Assembly, and x86 Assembly with AVX vector instructions.

  • Performance Features: Supports multithreading for faster processing.

  • User Interface: Built in C#, including histogram visualization for both original and pixelated images.

    Nixie Tube Clock

First Prototype 		LED Display
PCB Design

This project combines retro Soviet Nixie tube displays with modern IoT functionality to show time, date, temperature, and humidity.

  • Display: Uses authentic 170 V Nixie tubes for a vintage aesthetic.
  • Sensors: Includes a gas sensor for detecting CO levels.
  • Hardware: Built around an ESP32 microcontroller.
  • Companion App: Allows users to set alarms and interact with the device remotely.
