att hackathon / Mbed 2 deprecated DallasHackathon

mbed application board program with most libraries pulled in to create a feature rich starting point for hackathons

Dependencies:   C12832_lcd EthernetInterface HTTPClient LM75B MMA7660 mbed-rtos mbed

Fork of HTTPClient_HelloWorld by Donatien Garnier

AT&T M2M Mobile App Hackathon

• DFW 09-14 & 09-15
• Attendee List
• API Details
• Winning team pitches idea to ATT Executives on Tuesday 09-17-2013

Team's Project Pitch Notes

• Car location and tracking system (GPS + Wifi + Cellular)
• Temperature / auto vent control for home and industrial use (cellular + servo)
• GPS triangulation (sonar + cellular)
• Emergency Tool (Low cost OnStar / Sync Emergency Assistance)
• Remote Video Conference: Tele-presense (cellular and buttons. Rest was web services)
• M2M Billboard (LED + Cellular)
• Order management (restaurants) - Interrupt driven service. Not polled by wait staff (level sensor and cellular)
• pool manager (simulated ph and chem readings -> cellular)
• sprest - learning electronic sprinkler system (simulated moisture and weather readings -> cellular)
• safe traffic signals: stoprite (lots of statistics, used buttons and toy cars to create a scenario)
• Ecosense

Keywords Used Frequently During Presentation

• real-time
• MQTT
• Arduino
• 2lemetry
• HTML5
• Big data
• Server side

Participants

• ARM mbed
  • low use. No wifly modules and little/no wired Ethernet
  • ATT Github page with arduino stuff
• 2lemetry
• MSFT
  • One group hacked on windows phone, rest on android / iphone
  • Most were HTML5 (better looking ones)
