- 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 whatever 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?
