Ralph: The AI That Codes Itself

Ralph turns your computer into an autonomous coding assistant that builds projects by itself. It starts with a simple text idea, writes a technical plan, and then enters a continuous loop of writing code, testing it, and committing changes to git. What makes Ralph fascinating is that it treats your project files as its memory instead of relying on a temporary chat window. It remembers exactly what it did last time, fixes its own mistakes, and keeps working until the feature is finished. You can even swap in different AI models to run the tasks.

Polymarket 5-Min Arbitrage Bot

This Rust-based bot automatically hunts for pricing errors in Polymarket’s five-minute crypto prediction markets. It monitors the combined cost of buying both "yes" and "no" tokens and triggers a trade whenever that total dips below one dollar. Once both tokens are purchased, the code automatically merges them back into stablecoins, capturing a small but consistent profit from the pricing gap. It also handles risk management by balancing positions and cleaning up trades right before the timer runs out, offering a complete automated loop for short-term market inefficiencies.

📦 arrow-air/project-caribou

Project Caribou Drone Design

Project Caribou is the hexacopter project that finally treats every motor arm as its own independent power station. Instead of wiring one giant battery to six motors like a traditional drone, this design gives each of the six arms its own dedicated smart battery pack and custom safety board. The clever part is the hardware kill switch: a physical cutoff that cuts power at the battery stage before it even touches the electronics, ensuring the flight computer can never accidentally cause a short circuit. This repository collects all the engineering blueprints, custom circuit board files, and 3D models that make this safe, scalable drone architecture possible.
