The Tools Index

everything that does something.

One page for every tool in the universe — the civil-engineering rigs, the Pulse family, the FlipSuite arts, the quantum and space toys. Built by one engineer, kept in one place.

EVERY TOOL  ·  ONE PLACE  ·  ONE BUILDER

Civil & Hydraulic

The day-job lineage — watersheds, basins, scour, the things water does. Meet the engineer behind them: Lester Pearson, PE.
📝 Lester Pearson, PE — the Finale
The hydrologist who built these tools. GFAS, the Three Gauge Test, the forty-year FEMA typo.

Real-World Apps · the human's tools

The index of every real-world app — made for the human, not the machine. Each one reads a real federal or scientific database directly: you click a point and verify what a machine told you, instead of trusting it. Your data stays on your own phone — nothing aggregated, nothing harvested, nobody's server. Zero API calls to any platform, so a million people can hit it a million times a day and it costs pennies. Born out of AI collaboration, then handed back to people. Always check your numbers — but at least these are reading the source.
📊 SnapBasin
Click a point → a drainage basin built to TDOT spec, hitting every federal source. The flagship: ~6 hours of preliminary hydrology compressed to ~22 seconds — zero API calls.

Watershed Pulse
Tennessee River Basin health monitor — live USGS gauge data, read straight from the source.

🌏 QuakeSimulator
“What if it shook here?” Seismic what-ifs on a map, on published USGS hazard data — not a machine guessing.

🚀 Space Pulse
Listen to space, from anywhere — live feeds read direct.

QuantumPulse
Photons & qubits — the small strange things, hands-on.

🫀 PT Recovery Trackers
Seven joint-by-joint rehab logbooks — ankle, knee, hip, back, shoulder, elbow, wrist. Your sets, your data, your phone; between you and your PT.
