Parker talks with Brandon Satrom of Particle about the future of IoT and then design and prototype an IoT device.
  • 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
      • Individually Calibrated with NIST Traceable serial number
      • 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
      • Get code for this
      • 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
    • Another Particle Photon pulls data from the particle cloud and drives a relay board
    • 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

About the Hosts

Parker dillmann
  Parker Dillmann

Parker is an Electrical Engineer with backgrounds in Embedded System Design and Digital Signal Processing. He got his start in 2005 by hacking Nintendo consoles into portable gaming units. The following year he designed and produced an Atari 2600 video mod to allow the Atari to display a crisp, RF fuzz free picture on newer TVs. Over a thousand Atari video mods where produced by Parker from 2006 to 2011 and the mod is still made by other enthusiasts in the Atari community.

In 2006, Parker enrolled at The University of Texas at Austin as a Petroleum Engineer. After realizing electronics was his passion he switched majors in 2007 to Electrical and Computer Engineering. Following his previous background in making the Atari 2600 video mod, Parker decided to take more board layout classes and circuit design classes. Other areas of study include robotics, microcontroller theory and design, FPGA development with VHDL and Verilog, and image and signal processing with DSPs. In 2010, Parker won a Ti sponsored Launchpad programming and design contest that was held by the IEEE CS chapter at the University. Parker graduated with a BS in Electrical and Computer Engineering in the Spring of 2012.

In the Summer of 2012, Parker was hired on as an Electrical Engineer at Dynamic Perception to design and prototype new electronic products. Here, Parker learned about full product development cycles and honed his board layout skills. Seeing the difficulties in managing operations and FCC/CE compliance testing, Parker thought there had to be a better way for small electronic companies to get their product out in customer's hands.

Parker also runs the blog, longhornengineer.com, where he posts his personal projects, technical guides, and appnotes about board layout design and components.
