Show HN: ADSBee, an open source dual band embedded ADS-B receiver for anything I grew frustrated with closed source ADS-B receivers a few years ago, and wanted to build a true low cost embedded ADS-B receiver from scratch for low power applications. I ended up developing a custom radio frontend that uses RP2040 PIO for Mode S preamble detection and demodulation, and also released the first open soruce implementation of UAT decoding on an RF MCU from TI (which works somewhat beyond the publicly stated specs for the chip). Today, ADSBee is a fully featured dual-band ADS-B receiver, with Mode S, ADSB, UAT ADSB, UAT TIS-B / FIS-B, a ton of configurable reporting protocols, WiFi / USB / Ethernet, and a web server. Beta testers have been using ADSBee to feed everything from online data aggregators to drone autopilot systems and tablets running Electronic Flight Bag apps like ForeFlight.

I'd love to hear what people think about the project, or answer any questions. I've been posting regular updates to the blog on my website, it's been a very fun journey taking an open source hardware project from an idea to a business that makes and ships real things: https://pantsforbirds.com/blog/

Show HN: AI video generator that outputs React instead of video files

Show HN: AI video generator that outputs React instead of video files Hey HN! This is Mayank from Outscal with a new update. Our website is now live. Quick context: we built a tool that generates animated videos from text scripts. The twist: instead of rendering pixels, it outputs React/TSX components that render as the video.Try it: <a href="https://ai.outscal.com/" rel="nofollow">https://ai.outscal.com/</a> Sample video: <a href="https://outscal.com/v2/video/ai-constraints-m7p3_v1/12-01-26-18-47-41" rel="nofollow">https://outscal.com/v2/video/ai-constraints-m7p3_v1/12-01-26...</a>You pick a style (pencil sketch or neon), enter a script (up to 2000 chars), and it runs: scene direction → ElevenLabs audio → SVG assets → Scene Design → React components → deployed video.What we learned building this:We built the first version on Claude Code. Even with a human triggering commands, agents kept going off-script — they had file tools and would wander off reading random files, exploring tangents, producing inconsistent output.The fix was counterintuitive: fewer tools, not more guardrails. We stripped each agent to only what it needed and pre-fed context instead of letting agents fetch it themselves.Quality improved immediately.We wouldn't launch the web version until this was solid. Moved to Claude Agent SDK, kept the same constraints, now fully automated.Happy to discuss the agent architecture, why React-as-video, or anything else.

Show HN: SubTrack – A SaaS tracker for devs that finds unused tools

Show HN: SubTrack – A SaaS tracker for devs that finds unused tools Hi HN,I built SubTrack to help teams find unused SaaS tools and cloud resources before they silently eat into budgets.The motivation came from seeing how hard it is to answer simple questions: – Which SaaS tools are actually used? – Which cloud resources are idle? – What will our end-of-month spend look like?SubTrack connects to tools like AWS, GitHub, Vercel, and others to surface unused resources and cost signals from one place. Recently I added multi-account support, currency localization, and optional AI-based insights to help interpret usage patterns.This is an early-stage project and I’m actively iterating. I’d really appreciate feedback—especially from people managing cloud or SaaS sprawl.
