Desktop tools, embedded hardware and utilities for Linux/KDE.

▶ Sencurio LITE 1.0 — a smart home-safety sensor without a camera — a first look at the device from my Sencurio project: it knows when someone is home without using a camera, monitors temperature, humidity and air quality, alerts by voice and over Wi-Fi, and runs from the mains with a backup battery. (Video in Czech)

KiCad schematic symbols, footprints and STEP 3D models for parts without ready-made library support, built from official datasheets.

• ESP32-S31-WROOM-3 — STEP 3D model — a detailed STEP model of the Espressif ESP32-S31-WROOM-3 module
• IWRL6432WMOD — KiCad symbol & footprint — schematic symbol and footprint for the TI IWRL6432WMOD 60 GHz mmWave radar module

A set of tools for the look of Fedora with KDE Plasma 6, in one repository. Each part is standalone:

• Panel & Window Colours — a native settings module (KCM) for panel, title bar, border and shadow colours, plus saved themes with a live preview (colors/)
• Outline Icons — an outline icon set; the Accent variant follows the Plasma accent colour, plus fixed White and Black (icons/, Python, freedesktop)
• Expanding Icons Task Manager — an icon-only task manager; the icon under the cursor smoothly expands into a label with the window title and neighbouring icons move aside. It is a port of the app rail from the svec-elektro.cz header. Icons and labels stay readable on any background thanks to a contrast outline from a custom shader (taskbar/, QML, GLSL, KDE Plasma 6 widget)
• Plasma Search Bar — a VS Code–style command palette in the KDE panel: live KRunner results and prefix modes (> terminal, / files, : system actions, ! web, ? help), aliases, recent items and configurable features (QML, KDE Plasma 6 widget) (search-bar/)

An open-world simulator of the village of Dukelčice on a real cadastral map — NPC dialogue, work, skills, weather, wildlife, flying (Godot 4.3, GDScript)

A platformer that runs entirely in the browser (vanilla JS, Canvas, Web Audio API), with its own map editor

An interactive compression and communication simulator — a visual node editor with real-time data-flow simulation (Python, PySide6)

A KDE Plasma 6 wallpaper that renders the animated PSP XMB waves from system_plugin_bg.rco files (C++, Vulkan/OpenGL RHI)

A TUI manager for diagnostic, security and pentest tools on Fedora KDE (bash, whiptail/dialog)

Internal / non-public repositories — code, configuration and internal documentation stay private. A short overview without sensitive details (no credentials, internal IP addresses, customer data, etc.):

A monorepo for assisted living and home safety monitoring (AAL / smart home): mmWave radar + ESP32-S3 edge devices, a Laravel backend, a Next.js dashboard, an Expo mobile app and a PySide6 desktop monitor. Not labelled as a medical device. PHP/Laravel TypeScript/Next.js Python/PySide6 ESP-IDF MQTT

A desktop GUI/TUI work environment for Fedora: a kiosk shell (Wayland), a plugin API, a local AI agent and management of the static svec-elektro.cz website. A tool for my own daily use, not a product for distribution. Python PySide6/Qt JavaScript Rust

An independent multiplayer engine (Godot 4) built on the physics of a classic DOS platformer, with a LAN deathmatch for 2–4 players. BYOG (Bring Your Own Game) — the repository contains no original game assets. GDScript Python

An STM32 Nucleo-H753ZI as a replacement controller for an industrial 24 V I/O board — hardware reverse engineering for my own workshop, with terminal documentation and RE findings. C STM32 HAL

A summary across all repositories, public and private (stone-and-clay, HardCoreMode, infoflowlab, Vlnky, Fedora-SecuriTUI, svec-studio-fedora-theme, k3x020-nucleo, svec-studio, PRE2MULTI, sencurio-developer), by bytes of code as counted by GitHub — no file contents are used. I excluded vendor libraries and third-party add-ons (STM32 HAL/CMSIS, ESP-IDF managed components, Godot add-ons, Three.js/floorplan3d JS libraries) with .gitattributes (linguist-vendored), so the graph reflects the code I wrote, not the SDKs and plugins I linked:

Python JavaScript / TypeScript Rust PySide6 / Qt C++ GDScript Bash STM32 / ESP32 Godot Laravel Next.js
