Building a rocket involved wiring sensors to the Raspberry Pi. Custom coding the telemetry data with Node.js. Cutting and assembling the soda bottles to house the electronics. And a bottle that houses the pressurized water that makes the rocket fly.
Putting a rocket together took most of the day with assembly and QA testing. As this was an Atlassian sponsored activity we wanted to add a little extra incentive. We offered Amazon gift cards to the team that had the best integration with HipChat using Atlassian Connect.
Many teams put together a good effort and we're happy with what the winners came up with. You can see more from that day as well as an interview with the winning team in the video below. The Atlassian's team rocket launched their rocket five times that day.
