At this year’s Funk Hackathon in Mainz we developed a platform to organise and participate in protests all around the world. This platform helps to strengthen the democracy we live in by bringing together organisers and participants for protests against right-wing ideology, nationalism or for animal’s rights. In the last couple years, young people have often been accused of not being political. A generation where political activism equals clicktivism or slacktivism that remains digital, but fails to show visible dissatisfaction with policies on the streets. The visibility of the moderate majority in our societies has been overshadowed by populists, who have been able to make pan-European connections both in their protests and their communication campaigns. However, with Brexit and Trump as painful[…]

This year’s Hackathon Stuttgart took place in the beautiful Römercastel location in Bad Cannstatt. This is a huge building with plenty of places to work and sleep at night. This hackathon is organized by logicline. The Idea When it comes to hackathons I am always a fan of crazy projects you wouldn’t or cannot do at home. In this case we were interested in Car2Go and Kärcher (which is a German company producing machines and equipment for cleaning) – both provided interesting hardware for the event. Car2Go had different versions of their cars and Kärcher had a street sweeper. After looking at the different APIs we chose the street sweeper to work with because it just provides more capabilities. It has multiple sensors and interfaces to[…]

THack was a hackathon organized by the airport administration. The hackathon took place within SFO – the airport of San Francisco. Larissa and I decided to participate in the hackathon before flying home. Inspiration Two German developers came to San Fransisco two years ago for Apple Developer Conference. Looking for a cheap and convenient place to stay, they booked a room at a hotel at Tenderloin, SF. However, they had no idea that Tenderloin was an unsafe place at nights. So, they were followed by a drunk person late night on their way to the hotel. Two years later, an international team of students from Germany, MIT and UC Berkeley came together to take revenge. They created SafeStay that helps travelers to visualize[…]

This is a cultural music radio which plays suitable music depending on your gps location or travel route. Our backend server looks for artists and musicians nearby the user’s location and sends back an array of Spotify music tracks which will then be played on the iOS app. We use a python server backend to process RESTful API requests. Clients can send their gps location and will receive a list of Spotify tracks which have a connection to this location (e.g. the artist / musician come from there). We provide a javascript web fronted so the services can be used from any browser. The gps location is determined via html5 location services. In our iOS App we get the user’s location and send it[…]

Evernote organized an AppleWatch hackathon in Zürich. I met there with Arik, whom I know from previous WWDCs.   We developed an Apple Watch app which helps to learn vocabulary on the go. We use different sensors to determine when the user is idling, for example waiting at a red traffic light. We then push a little exercise notification which includes one vocabulary. This can help to learn a new language on the go without a big effort. We received the second price for this project.

MealHub was our project at the Hackathon Stuttgart 2014. We developed this app to be able to meet new people, cook and eat together. The initial problem was the lack of lunch options at our university. But what if every dorm could be a canteen? Cooking for five people is not much more time-consuming than cooking for one or two. After all we received the “price for best project”. After winning the hackathon we decided to continue working on MealHub and release the app on market. We worked on a server infrastructure, that organizes and exchanges events between participants, an iOS app and an Android app. After several months of work, customer interviews and business studies we were able to release the app. Mache Essen und Kochen[…]

We developed an app which helps to collect donations for charity by running. People who participate pledge a certain amount of money for every mile you run which is then automatically collected and donated to the charity organization. You can select from different charity organizations manually who should receive the donations which are collected by your running activity.  

At IBM’s bluemix hackathon we developed an iPhone app with intelligent weather capabilities: The app can wake you up earlier when harsh weather conditions occur (for instance snow). It is also able to warn you before certain weather conditions appear using the weather forecast. All calculations are done on IBM’s bluemix backend system, which then sends out a push notification to our fronted iPhone app. Read more about the hackathon and our project on IBM’s website. After all we were rewarded with the first price for our project.

A single restaurant can have thousands of reviews. Way too much noise to actually get exactly what you may want. At Reviewily we help organize the reviews, ratings, and comments so you can dive directly into what you care about, what people mention a lot, and you can be a more informed customer. Using IDOLOnDemand API (Sentiment Analysis) we pin point specific topics people people care about when reading reviews & comments. We can detail how many positive and negative comments a topic generates. Thus, a better way to understand a restaurant or a product than just the 5 star rating system. We won the second price at this hackathon.  

Our goal was to create an API for connecting different mobile devices of all types to one big screen without huge afford for the users. Our product is web-based, which means you don not have to install any software on your device to use it. Therefore we used Websockets, so you just have to type in the server’s IP and can connect. Via our server’s webcam we take pictures of the different devices that should be connected. At this point some image processing was required. In order to separate the background from the foreground, we grayscaled our picture and programmed some kind of the Otsu algorithm to get the optimal gray-scale value. All pixels that are darker, are drawn black,[…]

We developed a game which can be controlled using a smartphone. The controller is a website which uses touch-input events which are then transferred to out server which displays the game on a large monitor-matrix. The school where this took place offers such an monitor-matrix, this is why we came up with this idea. Up to for players can play together using their smartphones as controller and seeing the game on the monitor matrix. The game itself is a jump-and-run game with multiple characters. All assets, the game and the remote control have been developed by our team during the hackathon. The game is programmed using processing and then exported as javascript-website. We received the first price for our project. The source code[…]
