Posts about some projects from students of Stuttgart Media University will address the progress, problems and howtos from their different project topics.

IoT with the Raspberry Pi – Part 1

~ mr143@hdm-stuttgart.de

Introduction to the project

As part of the lecture “Software Development for Cloud Computing” in summer term 2017 we primarily wanted to work on a project that has something to do with the Internet of Things. In more detail we decided to measure air quality using a Raspberry Pi with the MQ135 Gas sensor and send this data to our self-built cloud application to analyze it.

We started out by getting IBM Bluemix student accounts. Playing around with different Bluemix Services we found the IBM Watson IoT Platform which can display data you can send to it from other devices out of the box. Despite displaying the data in charts it is also possible to create rules and send alerts based on them and to authorize other Bluemixusers to manage your devices as well.

How to build an Alexa Skill to get information about your timetable

~ dm080@hdm-stuttgart.de

Introduction

With information technology today we can easily get any kind of information someone is interested in. Whether you want to know how the weather will be tomorrow or how to cook your favorite cake, you can find out almost anything today. But as a user it’s getting more important to gain information quickly, and in a comfortable way. Google for example did just that. If you are using Google’s search engine, then you either type in what you are searching for or you can just say it. With spoken language this feature can be used easier and the response you get is quicker.

Dapp Development on Ethereum

~ Patrick Hidringer

In this blog entry we take a look at how to develop a Dapp (‘decentralized app’) on the Ethereum blockchain network and enhance our development process through Gitlab’s continuous integration (CI) services. It is part of the examination for the lecture “Software Development for Cloud Computing”.

First, all the necessary technologies to develop a Dapp are shown and explained, followed by an example of a crowd funding smart contract. Finally, a possible CI setup for this kind of application is shown.

Livestreaming with libav* – Tutorial (Part 1)

Lifestreaming is the real deal of video today, however there aren’t that many content creation tools to choose from. YouTube, Facebook and Twitter are pushing hard to enable their users to stream vlogging-style content live from their phones with proprietary Apps, and OBS is used for Let’s Plays and Twitch streams. But when you want to stream events or lectures you are pretty much on your own.

In this series of posts I want to share the experiences I gained over the past couple of weeks while writing an application that captures video and audio and creates a simple livestream. This application is designed to be the basis of a simple streaming desktop application.  Continue reading →

Hello there, today we want to feature a project, we were working in the last semester. A Smart Mirror.
It’s not that new to build such a mirror and we’re not the first who built one. We still wanted to do it in another way with another focus. Instead of focussing on our own needs we wanted to build an open and extendable solution.
