Seastead Control & Monitoring Software Guide
Open-source solutions for operating your 40x16 ft seastead with 45° column support and dual 2.5m propeller propulsion
Project Overview
Your seastead design presents unique challenges for navigation and control:
Structure: 40×16 ft living area with 4 ft wide columns at 45° angles
Float configuration: Rectangle approximately 44×68 ft at column bases
Cable system: Cross-bracing between column bottoms with redundancy rectangle
Propulsion: Two 2.5m diameter propellers on submersible mixers
Power: Solar-powered with target speed of 1 MPH
Weight: Approximately 30,000 lbs with "tiny oil platform" drag profile
Key Consideration: Your platform's unique hydrodynamics and cable stabilization system require specialized control software that can handle differential thrust steering and potentially complex station-keeping algorithms.
Navigation & Control Software
For your seastead's propulsion system, you'll need software capable of handling differential thrust steering (using the two propellers independently for maneuverability).
PyPilot (Recommended)
Open-source autopilot system designed for boats, with strong community support.
Shinobi offers a good balance of features and efficiency, which is important for solar-powered systems. Its modern interface and API would allow integration with your navigation system for a unified control panel.
System Integration & Additional Software
Data Monitoring & Sensor Integration
Node-RED: Visual programming tool for connecting hardware devices, APIs, and online services. Perfect for creating a dashboard that combines navigation, power, and camera feeds.
Grafana + InfluxDB: For monitoring power consumption, battery levels, solar generation, and platform telemetry.
OpenCPN: Open-source chart plotter and navigation software that can integrate with PyPilot.
Communication Systems
OpenPlotter: Complete marine navigation system based on Raspberry Pi with AIS, GPS, and sensor integration.
Signal K: Modern, open-source data format for marine navigation that allows different devices and software to communicate.
Sample Integration Architecture
# Simplified system integration concept
1. PyPilot (modified) - Handles propulsion and navigation
2. Shinobi - Manages security cameras
3. Node-RED - Creates unified dashboard and automation rules
4. Signal K - Standardizes data exchange between components
5. OpenCPN - Provides navigation charts and planning
Implementation Considerations
Hardware Platform
Given the solar power constraints, consider energy-efficient hardware:
Single Board Computers: Raspberry Pi 4/5 or similar for low-power operation
Power Management: Implement sleep modes for non-critical systems
Redundancy: Consider backup systems for critical functions
Development Approach
Start with basic PyPilot installation and understand its architecture
Create a simulation environment to test differential thrust algorithms
Implement camera system with Shinobi or MotionEye
Develop integrated dashboard using Node-RED
Test in controlled conditions before full deployment
Important: The cable bracing system in your design may create unique hydrodynamic effects. Consider implementing sensor feedback from tension monitors on cables to inform the control system about sea conditions and potential stress on the structure.
Next Steps & Resources
Getting Started
Set up a test environment with PyPilot on a Raspberry Pi
Experiment with motor control using PyPilot's existing codebase
Install Shinobi on the same or separate hardware for camera monitoring
Begin developing the differential thrust control module
Create a basic Node-RED dashboard to unify system monitoring
Seasteading Communities: Consider connecting with other seasteaders for specific platform insights
