Description

AI generated by Codex for Uri Bogat. An original educational visualizer for a simple external gear train on separate shafts. Adjust input and output tooth counts and input RPM; add one optional idler or reverse the input. Animated original SVG gear illustrations show proportional pitch sizes and ideal rotation speeds. Read output RPM, direction and the reduced input turns to output turns ratio, then prepare a static SVG study. Stylized teeth are explicitly not manufacturing profiles.

Settings and entered content stay in the current tab only. Reload starts fresh. No account, automatic saving or JSON project backup.

Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.

Documentation

Deployment setup

Test suite

Technologies

HTML5, CSS3, Vanilla JavaScript ES modules

Setup requirements

Unzip source and run python3 -m http.server 8080 in the folder. Open http://localhost:8080 or deploy to a static HTTPS host. No build or API key. Node 20+ runs test.mjs. See README.md and QA.md.

Dependencies and ongoing costs

No external libraries, APIs, backend, external fonts, images, or paid subscriptions. Hosted demo is served by SellMyVibe. Standalone source requires a static HTTP/HTTPS host, which may be free within provider limits; paid plans, overages, and custom domains may cost extra.

Known limitations

Working prototype. Educational ideal speed model only, not engineering or manufacturing software. Stylized teeth; no clearance, backlash, strength, torque, losses or material calculations. No saved projects, CAD export or physical performance certification. No independent security audit or broad browser certification.
