A proof-of-concept for a <$35 offline audio device that delivers farming instructions in local dialects. Supports the Oracle69 D-Prize proposal for distributing proven agricultural practices in Nigeria.
# Oracle69 SRI Audio Device
**A proof-of-concept for a low-cost, offline audio device to deliver System of Rice Intensification (SRI) instructions to smallholder farmers in Nigeria.**
This repository contains the design, firmware, and documentation for a purpose-built audio player. Its sole function is to store and play pre-recorded agricultural guidance in local dialects, designed to overcome connectivity and literacy barriers for farmers in Ondo and Ekiti States.
> **This prototype directly supports the D-Prize Concept Note for the venture "Oracle69."**

## 🎯 Core Principle: Simplicity & Cost-Effectiveness
This device is intentionally a "dumb" audio player—not a smartphone or AI chatbot. This design minimizes cost (<$35), maximizes battery life, simplifies use for all literacy levels, and ensures perfect reliability offline.
| Aspect | Why It's a Better Fit for This Pilot |
| :--- | :--- |
| **Cost** | **Very Low (<$35).** No expensive smartphones, data plans, or server costs. |
| **Usability** | **Press button, listen.** Requires no literacy or digital skills. |
| **Reliability** | **Fully offline, long battery.** Works anywhere, independent of cellular signal. |
| **Scalability** | **Easy to clone and distribute.** Simple hardware is quick to assemble and repair locally. |
| **Focus** | **Distribution of proven knowledge.** Technology is an enabler, not the product. |
