I Stole This from the Military
By Data Slayer
“Built with $240 and zero remorse...
I put the newest long-range radio chip on a Raspberry Pi 5 — a $246 build that does what $20,000 military mesh radios do. I'll show you how I built it, how it compares spec-for-spec, and a live field test that proves it works. No subscriptions, no closed firmware, fully open-source.”

I Built a Mesh Network Across the World
By DataSlayerMedia
“That escalated quickly...
In my last video, I introduced Reticulum—an open-source protocol that could allow anyone to build networks without relying on traditional internet infrastructure. But there was one big question left unanswered: how far can it actually go?
In this video, I start with a simple setup inside my house and begin pushing the limits—testing communication across rooms, neighborhoods, and beyond using WiFi HaLow and mesh networking. The goal is simple: see if it’s possible to send real messages across distance without depending on ISPs, centralized servers, or the internet as we know it.”

The Internet, Reinvented.
By Data Slayer
“Unstoppable mesh.
In this video, I build a Reticulum RNode and prove that completely different radios — LoRa and Wi-Fi — can communicate through a hardware-agnostic networking stack. Reticulum routes traffic above the radio layer, automatically bridging dissimilar frequencies, interfaces, and modulation types. I then run it over Wi-Fi HaLow Haven nodes to create a long-range, encrypted IP mesh with no traditional infrastructure. Finally, I push it further by running ATAK across the network, demonstrating a fully open-source, decentralized communication stack in action.”
