Ryan

Ryan is a Senior Infrastructure Engineer in aerospace who spends his days keeping critical systems running and his nights tinkering with homelab projects that definitely don't always work on the first try. After years in the public sector and nonprofits learning that uptime matters most when the people are your end users and networks span multiple sites, he recently made the jump to the private sector where the stakes are just as high but the scale is... different.

He believes in learning by doing, especially by taking the hard way, and is always happy to chat about the "why" behind the tech we use every day, things like: why containerization, IaC, or why your homelab really needs 10Gb, 25Gb, or hell 100Gb networking. Fixing your motorcycles or car wrong is also part of the same journey, don't discount how deep the rabbit hole goes.

Long range, cheap comms through Meshtastic
Slava I. Maslennikov, Ryan

Learn how to configure, use, and abuse long-range, cheap communication devices through Meshtastic, without a license! Talk to friends, control remote devices, gather remote sensor data - all at low power use, low cost, with encryption.

This workshop is designed for experience levels ranging from 0/5 to 2/5:

  • Beginner: never touched Meshtastic
  • Intermediate: installed Meshtastic, played with the app, messaged people

Specifically, we’ll cover:

  • Hardware involved, mild theory
  • Configuration and set-up
  • Messaging and interacting with others
  • Working with telemetry and sensors
  • Basic walkthrough of controlling remote devices
  • Show and tell of several projects that use Meshtastic
  • How to keep advancing after the workshop

For the price of admission ($50), you’ll receive hardware you’ll be working with at the workshop, that you will keep:

  • Heltec v3
  • 4000mAh battery
  • Temperature/humidity/barometric pressure sensor
  • GPS sensor
  • A custom case to house all of the above
  • An ultrasonic distance sensor
  • Stickers
