EP#122: Brandon Satrom and the LANoT

• Brandon Satrom
  • Developer evangelist for Particle
  • The founder of Carrot Pants Press
  • Loves to talk about Javascript, open source, microcontrollers, robots, and what ever new shiny tool or technology that is currently distracting him
  • Kitchen Sink of badges designed for Maker Faire San Mateo.
  • Favorite Bagel
• Blinky of IoT
  • Parker unboxed a Particle Photon
  • Included in the box is a photoresistor, a LED, breadboard, and some resistors
  • Parker built the circuit and programmed the Photon in under 5 minutes
• Building an IoT Device
  • Spec Sensors 3SP Ethanol 1000
    • Low Power Consumption of around 10 to 50 uW
    • 0-1000ppm Ethanol range
    • It has 3 analog outputs 
      • Vgas which is proportional to the gas we are measuring
      • Vref which is around half the supply voltage and is used as a fixed zero reference
      • Vtemp is the temperature of the sensor used to set the temperature compensation
  • Particle Photon reading the analog outputs of the Spec Sensors 3SP Ethanol 1000
    • Posts to the cloud about the status of the sensors
    • Code for this can be found here
    • Issues porting the Arduino Code to the Particle Platform 
      • Floats -> Doubles
      • Particle.Variable do not show up if you are doing Particle.Publish too fast
  • The relay board is connected to an industrial light tower 
    • Light tower - NPTL5-W-E 
      • 24V
      • Pull down I/O lines to turn on lights
• Discount codes for MEP Listeners
  • Particle is giving MacroFab Engineering Podcast listeners a discount
  • Use the URL https://store.particle.io/discount/MacroFabFam to get 15% off anything in the Particle Store
  • For free shipping use the code “"ParticleFamShipping"
  • Gets a free starter kit with the mesh Particle boards by using the code "ParticleFamStarter"
• Announcements
  • Houston Hardware Happy Hour
    • June 7th at Slowpokes
    • Bring hacks and hang out
