  Zephyr is a compact LoRa communication device designed for trust-based messaging. Built with pocketability and offline resilience in mind, it aims to support intentional connection without distractions.

   Core Features

  • E-ink display: Promotes low-power use and slows interactions, helping users engage mindfully.
  • Extendable LoRa antenna: Enhances range for peer-to-peer mesh networking, ideal for remote communication.
  • GPS SOS functionality: Adds a safety layer—users can send emergency signals even in off-grid scenarios.
  • Modular build: Enables easy repairs, customization, and sustainable design practices.

   Potential Use Cases

  • Backcountry or rural messaging with no cell coverage.
  • Community organizing tools in low-infrastructure areas.
  • Secure communication during events or fieldwork.
  • A quiet alternative to smartphones for those seeking digital detachment.

• Building the Sendrel Ecosystem

  Jeremy • 07/27/2025 at 07:11 • 0 comments

  When I first began designing Sendrel, I imagined a singular device—a quiet terminal for trust-first, offline messaging. But as the design matured, I realized the strength of Sendrel wasn’t just in its functionality, but in its adaptability.

  That realization led me to expand Sendrel into a suite of devices, each shaped by different use cases.

  • Sendrel Core: Something you can rely on, a central device to store and back up message threads.
  • Sendrel Terra: Built for outdoor deployment, disaster coordination, off-grid communication
  • Sendrel Zephyr: A pocketable companion for everyday mobility, balancing simplicity with presence

  Each form factor shares a common soul: no cloud, no surveillance, no assumptions. Just presence, trust, and consent.

  I didn’t want Sendrel to scale like software—I wanted it to echo like stories told in different voices. Different needs call for different tools, but the core values never change.

  I still plan to begin with Sendrel Core—formerly the Sendrel Terminal—to deepen my understanding of the system’s behavior before shaping the more complex forms.

  I've continued to iterate on the Sendrel terminal, trying to remove complexity and streamline the user experience, reinforce Sendrel’s core values, and respect the constraints of both materials and manufacturing.

• Concept Log: Why Sendrel Exists

  Jeremy • 07/22/2025 at 00:08 • 0 comments

  This project is still in its early conceptual phase—but even now, I believe it’s worth building.

  Sendrel began as a question: What would communication look like if it were rooted in trust, locality, and consent rather than scale or speed? As our digital networks grow louder and more centralized, I wanted to explore a quieter, more intentional alternative. Not just software—but physical terminals that feel like tools instead of toys.

  Right now, I’m sketching out Sendrel’s hardware design, interface flow, and pairing logic. It’s far from complete, but the core ideas are solidifying:

  • Real-world ID exchange to foster presence and accountability
  • LoRa mesh messaging without the need for Wi-Fi or cellular infrastructure
  • A minimalist, retro-inspired interface with tactile input and an e-ink screen
  • Focus on consent-first communication, where users opt in actively, not passively receive

  I see Sendrel as more than a device. It's a philosophy wrapped in hardware: communication as a ritual, connection as a choice, and networks as ecosystems—not pipelines.

  There’s plenty still to prototype—firmware, encryption logic, physical casing—but I wanted to share my intent early so that others can weigh in, challenge it, or maybe even help shape it.

  If this idea speaks to you, feel free to reach out, share thoughts, or contribute. The project might be quiet by design, but the conversation around it doesn’t have to be.
