ANPS-TradeMeUp - LLM-powered AI News Prediction System for short-to-medium term market forecasting, featuring real-time analysis and a Dash-based monitoring dashboard. License: Proprietary source-available (strict).
CrawlLama - Local AI agent that answers questions via Ollama and integrates web- and RAG-based research.
A-AIO-process-optimization-and-training - This is a testing / prototyping repository for experimenting with AOI/AI concepts and implementing them as clean, reproducible building blocks. License: Proprietary. No permission is granted to use, copy, modify, or distribute this software without prior written permission.
IoT & Embedded
ESP-ProMicro-HidKey - A multi-password USB HID keyboard emulator for the Arduino Pro Micro (ATmega32U4). Different button press sequences trigger predefined passwords, typed automatically over USB.
ESP32-Multi-OS-Launcher - Minimal firmware launcher that allows installing and switching between different ESP32 firmware builds from an SD card. Intended for projects where multiple applications are too large to fit in flash simultaneously, enabling the user to select and flash the desired firmware at boot.
Security & Cryptography
GPG-Meister - Local-first desktop app built around GnuPG for managing PGP keys, encrypting and signing messages, and exporting encrypted key backups. Supports English and German UI. License: MIT.
Network Security
FritzDump - Live FRITZ!Box packet-capture helper that streams pcap data to Wireshark, ntopng, files, or stdout, with PBKDF2 login support and optional metadata-only redaction. License: MIT.
Games
ZombieEscape - Open-world, location-based zombie survival game for Android that turns real streets and buildings into a survival map. This is a preview repository featuring production updates, playable alpha, beta and test builds to evaluate, development insights, and contact options to get involved — the main repository is kept private. Current phase: feature implementation, bugfixing and polishing.
