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/)

A pixel-art companion for Claude Code: a little character sits on the title bar of the terminal where the agent runs and shows what it is doing. It thinks, works with tools, waves when it needs permission, stumbles on errors and falls asleep when idle. It also has a mood guessed from the conversation, a context-usage battery, helper drones for subagents and swappable skins with a built-in editor, including a Christmas Robo-kun (Python, PySide6, KDE Plasma 6 / GNOME / X11; code MIT, skins CC BY 4.0)

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
