MEP EP #151: Why Mesh Networking Matters – Brandon Satrom

Podcast Notes

  • Brandon Satrom
    • Developer Advocate for Particle, an IoT platform company
    • The founder of Carrot Pants Press, a company dedicated to educating makers
    • Loves to talk about Javascript, open source, microcontrollers, robots, and what ever new shiny tool or technology that is currently distracting him
    • On the MacroFab Engineering Podcast Episode Number 122, Brandon discussed the Particle Photon and built an IoT breathalyzer with Parker live on the podcast
  • What is currently distracting Brandon now?
    • Why mesh networking matters (as opposed to putting Wi-FI and Cellular radios in every IoT device)
    • Existing mesh networking standards (Z-Wave, Zigbee, Lora)
      • Closed vs. Open standards
    • Thread/OpenThread and why Particle built OpenThread into 3rd gen devices
    • Mesh Christmas Tree project
      • 5 device network with a gateway and 4 edge devices
      • Particle Blog detailing more about the project
      • One edge device publishes multicast messages to all other nodes, which light up neopixel strips when those messages are received on each device
      • The goal was to see how low latency UDP-based mesh messaging was
      • Researching theory around “the color of sound” and added a mode to the firmware that converts the frequency of a played note into a corresponding rgb value on the color spectrum. Kinda.
      • Working today on a mode that ties the Adafruit Neotrellis into the network to create a “tree synth” mode where you can mash buttons and make the trees light up
  • Questions from Jarret from our Public Slack Channel
    • Could you have a sportsgame of some sort, and hand out each spectator a little LED/LCD with mesh chip, and have all 10k systems attempting to figure out where they are in the stadium, and maybe also connect to a base station, so they all receive color information and turns the audience into a huge display?
    • What is a good distributed power system for mesh networking?
    • I’ve started logging metrics for my indoor garden, but currently I’m using a million phone chargers plugged in everywhere and that kinda sucks
  • Update on the Carrot Pants Press?
