Hello
DB Fernverkehr AG and DB Systel GmbH hosted the DB Open Data-Train Challenge on March 20 and 21 in Frankfurt am Main. This was a 24-hour hackathon in which participants were given access to historical data from train journeys, which they could then use for their own project ideas.
A total of 65 participants divided into 15 teams took part in the competition. The challenge started on Friday at 5 p.m. and ended 24 hours later - with the presentation of the results in front of the jury and the other participants. The event took place in the Silberturm, an impressive location in Frankfurt am Main.
Let's dev also provided a team and realized an Android smartwatch application as well as an Android app for smartphones within the 24 hours. The smartwatch app maps various functions:
The Android smartphone app obtains the required data in JSON format and prepares it so that the data can be processed by the smartwatch. The Android smartphone app communicates with the smartwatch app via Bluetooth Low Energy (LE).
With the project idea, the realization as well as the successful presentation the team prevailed against other exciting and impressive projects and secured the category award "Best Presentation". In addition to the video published by the organizer, a few impressions of the event can be found below. Our thanks go to the organizers and participants for the great event!
