Use your Raspberry Pi as your local NodeJS Webserver

June 12th, 2016 1 comment

A couple of months ago, I tinkered around with NodeJS on my local machine. After a while I got kinda addicted to the NodeJS Plattform for webservice (SOA) applications as well as Desktop Apps (Electron/NodeWebkit). Hence more complicated NodeJS experiments will start, I decided to set-up my own webserver environment for my (local) network with a Raspberry Pi 2 B. My tools of choice are:

  • Raspian Jessie Lite from 2016-05-27
  • GIT v2.1.4: Version control for source code
  • NodeJS v6.2.0: for REST APIs and Websocket applications
  • Nginx Webserver: Deliver static files, Reverse Proxy for NodeJS, and Load Balancing
  • MySQL Server and Client: for Relational Databases
  • CouchDB v1.6.1: as my NoSQL Database with strong JavaScript tools
  • PM2: NodeJS Process Manager for starting and stoping NodeJS Apps
  • Nodeadmin: Admin Tool for MySQL (like PHPmyAdmin)

Let's get started:

 

Download Raspian Jessie Lite from the foundation website and write the image on your class 10 SD Card. For more information please read this tutorial (in German).

Guestlecture and Workshop Human Plant Interfaces

Plant Colour Patterns

On May 2015, Myriel Milicevic invited me for a Guestlecture & Workshop on Artistic Human Plant Interfaces/Elektrobotanik for her Interfacing with Nature class at University of Applied Science Potsdam. The starting 90-120min lecture provided the students (in that case communication, product, and interface designer) an introduction about interfaces with plants. This includes viusal approaches as well as bio sensing projects.

Workshop Format: Create a Game (Art) Installation

May 7th, 2016 No comments

During mid of 2013 until the beginning of 2014, Juliane Springsguth and me had the chance to develop a new game design hacking workshop format for teenagers (Mostly 8th graders around 13-15 years old) in cooperation with "Berufsorientierte Schulprojektwochen (BOP)" organized by the Media Education Institution WeTeK Berlin gGmbH.

Our objective was to generate a tangible and audiovisual output in shape of a Game (Art) installation during the workshop. Furthermore, our intention regarding those young participants was to empower them to express their ideas in a (media) technology driven environment. Officially the objective was that they get a first impression how a job as digital media worker could look like.

Create speaker on the body of a leaf

November 27th, 2015 No comments

For almost more than a year I wanted to write a tutorial about how to create a speaker on a leaf. Unfortunately, I found no time to write one. I think it is now time to show you the video as an example and provide you the links for built your own leaf speaker

For several years, I am really excited about Hannah Perner-Wilson aka Plusea's textile circuits. Fortunately, I could join her workshop during the Schmiede 2013 and applied her textile speaker to a lead of a plant. First experiment worked well with conductive thread, which kinda harmed the leaf structure. Therefore, we experimented with conductive ink, too. The result was much quiter noise.

Information and tutorials for building your own leaf speaker:

Falling in love with REST APIs and Backbone

February 28th, 2013 No comments

How I mentioned in my previous post, there is some stuff that I really like about developing with JavaScript. Especially, working with REST APIs and Backbone is so simple. There just a view steps to do. In my case I have chosen the Qype Rest API. Create your model and define your properties you want to work with.

Get in touch with JavaScript

August 26th, 2012 4 comments

Some time passed since this Adobe public relation dilemma about Flex and Flash happened. Honestly, it hit me very hard. Exactly at this time, I was diving deeper into the Flex 4 Component Framework and tried to adapt my new knowledge to Flex Mobile. After some failures and misunderstandings I was on a good way and I was convinced that the (new) Flex 4 Framework is a real step forward for developing User Interface. For this reason, I got a little bit mad about the whole discussion of HTML5 vs. Flex. I expected that HTML5 + CSS3 + JavaScript will come, but not so fast and powerful. However, I got a good opportunity and checked what it is all about this new hype of web technologies. As a Flex and Flash Develeoper the transition to this open standard development approach is not very difficult, except the tooling is like from another planet.  I had the feeling that finding the right tooling is as difficult as finding the appropriate life partner. There doesn't exist an one simple solution for everything like Flash Builder environment. In my case I recommend for writing Code to use the IDE Webstorm, for debugging I am using Firebug for Firefox. Whatever everyone has his own preferences, so decide for yourself what is the best.
