Projects
Selected work — hardware, embedded, and software
AD-LED Clock
ATmega8535 driven LED-Matrix clock with shift registers, brightness control, and time sync. Pure C++ at register level — no external libraries. Circuit designed in KiCad, housing fully 3D-printed.
Traffic Light System
Full street crossing simulation — traffic lights, pedestrian signals, day/night mode, ultrasonic sensors. Arduino Mega, LN298, interrupt-driven pedestrian buttons. Traffic light housings fully 3D-printed and CAD-designed.
Weather Station 2.0
Modular IoT weather station on ESP32. Multi-sensor fusion, WiFi telemetry, clean data pipeline. Each sensor module independently swappable — designed for extensibility from the start.
GO-CORE-LAB
Personal low-level research framework in Go. ELF/PE binary parsing, hardware bridge for SPI/I2C/UART capture from embedded targets, network probe module. Statically compiled — drop anywhere and run.
Home Lab — Server & Network
Private server infrastructure on Ugreen NAS. Docker services, Cloudflare Tunnels, VPN, VLANs, switch administration, monitoring. This website runs on it. Built and maintained entirely by hand.
Electronics Workbench
Personal electronics lab for embedded development and signal analysis. Oscilloscope, signal generator, bench PSU, SMD/THT soldering station. Signal capture (PWM, UART, I2C), PCB design with KiCad and EasyEDA, rapid prototyping with 3D print.
