Summary
- A low‑cost desktop solution that uses an SDR and automated spectral analysis to flag emissions that exceed common EMC/EMI limits before sending hardware to an expensive lab.
- Provides instant compliance scoring so manufacturers can prioritize fixes and reduce iteration costs.

Value |
| Target Audience |
Electronics manufacturers, freelance hardware designers, hobbyist compliance testers |
| Core Feature |
Automated emission detection with threshold‑based alerts and printable compliance report |
| Tech Stack |
Python (GNU Radio, NumPy), Qt for UI, SQLite for reporting, USB SDR dongle (e.g., RTL‑SDR or HackRF) |
| Difficulty |

| Monetization |
Revenue-ready: Subscription per user ($15 /mo) |
Notes
- HN users repeatedly cited the high cost and scheduling difficulty of lab EMC testing; this tool directly addresses that pain point (“expensive, time consuming and requires scheduling”).
- Could be packaged as a plug‑and‑play appliance for small firms, creating a clear business case and opening discussion about regulatory compliance software markets.
Summary
- A distributed network of inexpensive passive RF sniffers that triangulate unauthorized drone RF signatures and visualize detections on a real‑time map, similar to acoustic‑camera displays.
- Enables airports, stadiums, and large facilities to quickly locate hidden or rogue drones without costly active radar systems.

Notes
- Commenters emphasized the need for “local soft‑run testing” and “finding unknown RF sources across large assemblies,” which this system fulfills.
- Leverages the same passive‑array concept discussed for drone detection, promising a practical, scalable solution and sparking conversation about integration with existing counter‑UAS infrastructure.
Summary
- A web application that lets users upload raw RF capture files (e.g., .wav, .bin) and instantly generate spectral plots, frequency‑bands of interest, and basic compliance checks, all within the browser.
- Eliminates the need for expensive desktop analysis software, making RF insight accessible to hobbyists and researchers.

Notes
- Several HN remarks referenced “visualizer reminds me of acoustic cameras” and desire to “check for once” unknown RF emissions; this tool directly satisfies that curiosity.
- Open‑source nature encourages community extensions, potentially leading to a marketplace of custom analysis modules and fostering discussion about democratizing RF analysis.
