Engineering playground

Precision tools for motion, force, and acoustics.

A home base for the calculators and simulators I build — fast to open, clear about what each one does, ready for the next tool on the bench.

Live tools

Open any card. Each app keeps its own data credits and disclaimers.

Vehicles

VelocityBench

Explore acceleration, force, and timing for vehicle scenarios — a clean gauge-and-chart bench for dialing in performance intuition.

Open tool
Acoustics

Sound Distance Calculator

Estimate how suppressor muzzle levels fall off with distance — inverse-square SPL curves with OSHA reference lines for quick comparison.

Open tool
Firearms · Sound

Gunshot Sound Propagation

Map how a shot’s sound field spreads with wind, terrain, and Thunder Beast Summit–based bare vs suppressed profiles — plus OSHA distance tables.
