48 hours in Seattle

Monday, December 19, 2016

by Alex Donn, Kandy developer relations

From 48 hours of hacking, 50 gallons of coffee, 120+ creative thinkers, 21 hard-working teams came an awesome lineup of inspired ideas. Teams combined T-Mobile SIMs, boards and APIs from, and to create a number of unique and innovative hacks that a number of the judges said that they wish were on the market today. While there were seasoned developers in attendance vying for the $10k+ in prizes, there were also number of grade school, high school and university students who participated as well. Some even brought their own microprocessors such as Intel, Arduino, Tessel and Raspberry Pi boards.

Invisible computing was the theme explored at the recent Seattle Interactive Conference Hackathon, which was sponsored by a number of companies:, T-mobile,, Apptentive and By combining a communications API like with an IoT accelerator device like or Raspberry Pi, the developer teams created product prototypes that a number of the judges said that they wish were on the market today.

To frame up this coding challenge, we had Sharon Read from Seattle Tiny Home and Gene Ehrbar from HP how to invisibly integrate technology with efficient home design as well as production wearable design/development with the hope of helping the attendees see the larger picture of technology need within the ecosystem.

The “Internet of Things” can be a tricky space to navigate especially with so many hardware and software development options/preferences. Team USES was able to creatively leverage both and a Rapsberry Pi to create a home monitoring system that watched for motion and then notified the home owner via the SMS API and then as a second step, call the owner via video with the API. As a REST API,’s communication capabilities can be easily adapted to any platform as the students have so easily shown!

Big thanks goes out to T-Mobile,, Seattle Interactive Conference and for providing an insane amount of free hardware! Also to the mentors who brought their own gear to help with soldering, wiring and spare parts!

  • Github Repo: None
  • Technology Used: Particle io, Flashing Firmwares and getting the HTTP Request and Responses to work with the SMS.

Team Nahm - We’re Nahm and we created a system to measure water consumption in the home. Why? California is currently struggling through its worst drought in over 500 years and we expect this problem to spread to other states as water tables drop. While the problem is not entirely consumer consumption (hint, hint, … corporations), the government and utility companies are asking consumers to be more ""mindful"" with their water consumption, but how mindful can we be when we only see an end-of-month summary of gross water usage and a nice big bill to pay. We believe there is value in tightening the feedback loop between the water bill and consumption behavior. The device we made can be installed at water outlets, e.g. the shower, toilet, dishwasher using standard plumbing connections to provide greater insight into water consumption and empower consumers to take control of their water consumption behavior. Additionally, this device can be a channel for utility companies to gamify and reward water conscious customers." among others.

  • Github Repo: None
