Interactive, zero-dependency automotive electrical & mechanical drivetrain simul
AutoCircuit Builder is an interactive browser-based automotive engineering and simulation suite featuring two specialized workbenches: ⚡ Electrical Workbench: 28 components (batteries, switches, relays, diodes, circuit breakers, colored lights, voltmeter) with a live graph-reachability current solver. ⚙️ Mechanical Workbench: 31 components (engine with real displacement & redline physics, clutch, transmission, differential, brakes, cooling, turbocharger) with power-limited top-speed simulation, live efficiency waterfall graphs, and fuel economy estimation. 🌍 Community Hub: Fully integrated REST API & PostgreSQL database allowing users to publish builds, like, comment, and remix each other's configurations with 1-click loading. Key Technical Highlights: • Zero-dependency frontend: Pure HTML5/Canvas/CSS and vanilla JavaScript (ES modules). Zero build tools, zero Webpack/Vite complexity, and instant load times. • Turnkey backend: Lightweight Express.js API + PostgreSQL database on Render. • Turnkey monetization ready: Pro Mechanic ($9/mo or $49 lifetime) and Educator/Classroom ($199/yr) pricing tiers, watermark-free Ultra-HD exports, and Bill of Materials (BOM) CSV parts generator. Single-file Stripe configuration in js/proConfig.js. What's Included: Complete private GitHub repository ownership & source code (Frontend + Backend). PostgreSQL database schema and live community data (builds, comments, likes). 59 custom SVG automotive component vector designs. Comprehensive Buyer Handover Guide (BUYERHANDOVERGUIDE.md) and Asset Transfer Manifest. 14 days of post-sale onboarding support.
Next step: <p>1. B2B Vocational & STEM Licensing: Sell classroom licenses ($199–$499/yr) to automotive trade schools, community colleges, and STEM high schools for circuit and engine diagnostics.</p><p>2. Automotive Creator Partnerships: Partner with or embed the interactive simulator on car enthusiast forums, automotive blogs, and YouTube channels.</p><p>3. Component Brand Sponsorships: Partner with automotive aftermarket brands (battery, turbo, brake manufacturers) to feature branded parts on the canvas.</p><p>4. Mobile / Tablet PWA: Package as an iPad/tablet app for hands-on automotive mechanic workshops.</p>
