Open-Source Exam-Approved Calculator with Modern Dev Environment
P6/10May 1, 2026
WhatAn affordable, open-hardware graphing calculator that ships with a full Python environment and meets standardized testing requirements, undercutting TI's pricing by 60%+.
SignalThere is widespread frustration that TI charges $160 for hardware with an estimated $10 bill of materials, while competitors like NumWorks already prove the market will accept alternatives — TI's dominance rests on institutional inertia, not product superiority.
Why NowPython is now part of standardized math curricula in multiple countries, NumWorks has proven exam boards will certify non-TI devices, and component costs for color-screen ARM-based devices have cratered.
Market15M+ graphing calculators sold annually in the US alone, primarily to high school and college students; key gap is TI's near-monopoly pricing power with no credible scaled challenger in the US market.
MoatExam board certifications create a regulatory moat — once approved for SAT/ACT/AP, switching costs for school districts are high and competitors face a multi-year certification process.
Universal Cable Intelligence Platform for All DevicesP5/10A cross-platform hardware diagnostics tool that identifies the real-world capabilities of any connected cable, adapter, or dock — not just USB-C — across Mac, Windows, Linux, and mobile.
Verified USB-C Cable Certification and Testing ServiceC5/10A hardware testing service and consumer database that independently verifies USB-C cable capabilities against their marketed specs, exposing counterfeit and underperforming cables with a searchable ratings database.
Automated Kernel Vulnerability Mitigation Deployment ServiceC7/10A managed service that automatically deploys eBPF-based or config-based mitigations to production Linux fleets within minutes of a vulnerability disclosure, bridging the gap before official patches ship.
Hardened Linux Mount and SUID Policy EngineC5/10A security policy engine that enforces least-privilege filesystem mount options (nosuid, nodev) and audits SUID binary exposure across Linux systems, with NixOS-style isolation as the default.
AI-Powered Stylometric Deanonymization Defense PlatformP7/10A privacy tool that rewrites text in real-time to strip stylometric fingerprints while preserving meaning and readability, protecting users from AI-based author identification.
