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).

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:

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
