RuView project leverages ESP32 nodes for WiFi-based presence detection, pose estimation, and breathing/heart rate monitoring
RuView is an open-source "WiFi DensePose" implementation leveraging multiple ESP32 nodes to turn WiFi signals into real-time human pose estimation, vital sign monitoring, and presence detection without relying on video cameras. WiFi DensePose is a sensing technique, first explored in academic research, that leverages WiFi signals to reconstruct human pose. RuView implements this technique in Rust or Python, and relies on your WiFi router and several ESP32 nodes to track body pose, detect breathing rate, and measure heart rate even through walls. As we'll discuss below, this project has its own controversy, as some claim it's fake. The solution relies on Channel State Information (CSI) disturbances caused by human movement to reconstruct body position, breathing rate, heart rate, and presence in real time using "physics-based signal processing and machine learning". That obviously means you need CSI-capable hardware, and not all consumer WiFi nodes implement it. The project description lists various
Anyone out there experimenting with Reticulum? Building RNodes?

Hi Mastodon 👋
We're Node Star — a publishing and community project building neighborhood mesh networks in Southern California and beyond.
We just published a free community playbook: "Own the Internet: Neighborhood Networks That Can't Be Shut Down."
Written for the person who wants to start, not the person who already knows how.

How-To Geek: This tiny radio lets me send texts without Wi-Fi or cell service . “Reading about community resilience recently, I came across talk of something called Meshtastic and how it lets you stay in touch with people miles away even if your internet access and the power grid itself were shut off.”

In 2030 Barcelona, the internet is a corporate prison. One hacker holds the key to freedom.Andrés "PingStarved" Reyes spent decades fighting for digital liberty, but the cost was everything—his relationships, his family, his soul. Now 56 and living in isolation, he watches surveillance capitalism strangle the web he helped build.When mysterious forces target his old friend—a surveillance company CEO who sold out their shared ideals—and threaten to unleash chaos unless Andrés surrenders his greatest creation—a revolutionary mesh networking protocol that could free global communications—he faces an impossible choice.Work alone, as he always has, and watch the world burn. Or trust a new generation of hackers who've revived forgotten internet protocols, built resistance networks in the shadows, and still believe technology can serve humanity instead of enslaving it.From Barcelona's smart-city surveillance to underground hackerspaces, this is the story of what happens when one of the last free hackers discovers that code isn't enough—sometimes you need connection.Perfect for fans of Neuromancer, Little Brother, and Mr. Robot. Features authentic hacker culture, real mesh networking technology, and modern attack techniques that cyberpunk readers will recognize as tomorrow's reality.
Live tracking with 4× LilyGO T-Beam SUPREME units.
Each node transmits GPS coords every 10s, logs TX/RX to SD, and stays µs-disciplined to avoid collisions. A Semtech SX1303 sniffer on an RPi 4B captures all traffic → UDP → CSV → live web map with fading positions. Includes 49 second video (sped up 500%).
