Tim Cash

I teach math and robotics for fun. Here I keep a small record and collection of my work.

What I Build

Clean, math-forward systems that translate equations into working machines, maps, and interfaces.

Pinned Repositories

  • Dialtone — AI-assisted CLI for designing, operating, and scaling large robotic video/data networks with a network-first architecture.
  • Code CAD — Web-based CAD powered by Python (FastAPI + CadQuery) and Three.js for parametric, geometric modeling and STL export.
  • Pipe — Encrypted P2P messaging demo with a Rust backend and Bun/TypeScript frontend for real-time communication.
  • AutoScreen — Desktop automation via image matching, built in C with SDL3 and a custom UI framework.
  • Earth Engine DEM — GIS viewer for DEM and road overlays with a game-like HUD, built with Bun and TypeScript.

Projects and Experiments

  • Global soil spectroscopy visualization and GeoJSON generation.
  • Math + code sketches for Mandelbrot, Lorenz, and multi-circle systems.
  • Visual explorations of spherical geometry and differential equations.
  • Chromatic Systems: fractals, complex numbers, and coloring algorithms.

Industrial Robotics

  • Robot programming and cell deployment with Fanuc, Yaskawa, and Universal Robots.
  • GD&T-driven fixturing, process validation, and tolerance-aware automation.
  • 3D laser scanning for metrology, alignment, and in-cell verification.
  • Adaptive weld sequencing for heat control, distortion reduction, and consistency.

Weather Modification

  • Drone-based cloud seeding using CCNs to induce precipitation.
  • Operations in cold and warm weather environments.
  • Led teams of engineers and scientists as Chief Technology Officer.
  • Weather radar processing algorithms for targeting and validation.
  • Flight controllers, DAA radar integration, rapid assembly, and FAA coordination.
