AERIS-10 is an open-source radar system that can detect and track objects — like drones or aircraft — up to 20 kilometers away, built with off-the-shelf components at a fraction of the cost of commercial radar. It comes with all the hardware designs, software, and a visual interface, so researchers or startups can build and customize their own working radar system.

§ 1 — what it does

AERIS-10 is an open-source radar system that can detect and track objects — like drones or aircraft — up to 20 kilometers away, built with off-the-shelf components at a fraction of the cost of commercial radar. It comes with all the hardware designs, software, and a visual interface, so researchers or startups can build and customize their own working radar system.

§ 2 — why it matters

Radar technology has historically been locked behind military contracts and multi-million dollar price tags, but this project could open the door for drone startups, airspace monitoring companies, and defense-adjacent ventures to prototype radar-based products without massive upfront investment. For founders, it signals a growing 'democratization of sensing' trend where capabilities once reserved for governments are becoming accessible building blocks for new commercial products.

§ 3 — why it’s trending

The idea of building a functional 20-kilometer drone-detection radar from off-the-shelf parts for a fraction of commercial costs has clearly struck a nerve — this project went from 119 stars last week to over 10,000 in a single week, an 8,400% acceleration that signals a viral moment rather than organic growth. The timing makes sense: as drone incidents near critical infrastructure dominate headlines, researchers and defense-adjacent builders are actively hunting for affordable, hackable alternatives to expensive proprietary systems. With 178 commits in the last 30 days and over 3,100 forks already, there's real hands-on interest here — people aren't just starring it, they're pulling it down and building with it.

New Expensify is an open-source rebuild of the popular expense management app, redesigned from the ground up around chat and real-time financial collaboration between teams. Instead of treating expense tracking as a back-office chore, it weaves money management directly into conversations, making it feel more like a messaging app than traditional accounting software.

why it matters: With nearly 5,000 stars and over 2,300 contributors, this project signals that Expensify is betting its future on a chat-first, collaborative financial workflow — a direct challenge to legacy tools like Concur and even newer players like Brex or Ramp. For founders and PMs, it's a live case study in how an established fintech company is open-sourcing its core product to accelerate development and build community loyalty while repositioning against a rapidly evolving competitive landscape.

Blender is a free, professional-grade 3D creation tool that handles everything from building 3D models and characters to animating them, adding special effects, and rendering final visuals — all in one package. It's the open-source alternative to expensive commercial 3D software like Maya or Cinema 4D, used by indie creators, studios, and game developers worldwide.

why it matters: With nearly 20,000 stars and over 1,400 contributors, Blender has become the default 3D production tool for budget-conscious teams, making high-quality 3D content creation accessible without licensing fees that can run thousands of dollars per seat. For founders building in gaming, film, virtual reality, or AI-generated media, Blender's open-source pipeline and active ecosystem represent a cost-effective foundation for content production workflows.
