Project Arrakis: The Open-Source SCADA for Home Spice Farming

An open-source, low-cost SCADA system using Raspberry Pi to automate and monitor small-scale, high-value indoor farming operations, integrating real-time market price data to maximize profitability.

Inspired by the resource scarcity of 'Dune' and the rugged independence of 'Star Wars' moisture farmers, Project Arrakis is a SCADA system for the modern homesteader. The concept casts the user as the head of a small, independent 'house' cultivating their own 'spice'—a high-value, niche crop like saffron, gourmet mushrooms, or wasabi, grown indoors. This project empowers individuals to compete against larger agricultural corporations by leveraging smart technology.

The system is built on a low-cost, accessible stack. A Raspberry Pi acts as the central control hub and Human-Machine Interface (HMI), running open-source software like Scada-LTS or a custom Python dashboard with Grafana. In the 'fields' (grow tents or shelves), Arduino or ESP32 devices function as Remote Terminal Units (RTUs). These RTUs connect to a suite of sensors (monitoring temperature, humidity, pH, nutrient concentration, CO2 levels) and control actuators (pumps, lights, fans, dosers).

The key innovation, inspired by the 'Retail Sales' scraper, is the CHOAM (Combine Honnete Ober Advancer Mercantiles) Module. This is a software component that scrapes web sources for the real-time wholesale and retail market price of the specific crop being cultivated. This financial data is displayed directly on the SCADA dashboard alongside production metrics (yield rates, resource consumption). This allows the 'farmer' to make data-driven decisions, not just about growing conditions, but also about when to harvest and sell for maximum profit, effectively creating a personal commodity exchange for their 'spice'.

The project is designed to be easy for individuals to implement, with modular components and detailed online guides. Its high earning potential comes not from selling the software, which is open-source, but from several potential business models: selling pre-configured hardware kits, offering premium cloud-based data analysis and forecasting services, or providing paid consulting for setting up specialized crop environments. It turns a simple gardening hobby into a sophisticated, data-driven, and potentially lucrative micro-enterprise.
