Use your Raspberry Pi as your local NodeJS Webserver

June 12th, 2016 17 comments

*** An updated version of the article is available here ***

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

May 12th, 2016 No comments

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.

Some findings of my master thesis about biosensing are published in the new book:

The Green Thread: Dialogues with the Vegetal World

Book about Plants

Edited by Patrícia Vieira; Monica Gagliano and John Ryan

Together with Christa Sommerer and Laurent Mignonneau, we wrote the chapter 13 The Art of Human to Plant Interaction. If you want to see videos of these featured Human Plant Interaction, please check: Biosensing for Human Computer Interactions

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:

Happy tinkering!

Plants as a barometer: “Charisma Garden”

October 20th, 2014 5 comments

The last introduced projects were characterized by its approach of attaching data to a plant. In this project “Charisma Garden” (2013 - 2014), the data will be directly integrated in the health and growth process of a plant. In comparison to the “Travelling Plants” and “Dead Tree Project”, the data is not added to the plant then rather the representation of the data is the plant by itself in this project. In relation to the chapter “3.1. Visualizing techniques with plants” on page 44, the “Charisma Garden” project can be assigned to the category plant displays and takes over the role as a data sculpture. This dynamic (visually changing) data sculpture presents the social activity of a Facebook user.

Digital Network and Community Design with plants

June 15th, 2014 9 comments

Plant Colour Patterns

After the introductions “Visualization techniques with plants” and “Biosensing for Human Computer Interaction” the next projects using some of the already mentioned techniques. However, this chapter focuses on various approaches of network and community designs. Previous Land Art initiatives and projects were always closely tied to social and cultural resonance. These efforts resulted in social activations of local communities and local conditions [KastnerWallis2010, pages 15-28].

Our exploration investigates the application of current technology and design tools in this field. We will start with community design approaches that do not need a physical presence of humans. Design approaches for location-based communities with a supportive use of digital communication technology will be described afterwards.
