windclocks:anemometer

Sun, 16 Jan 2011 19:03:20 +0200

In this setup we use the inspeed Vortex anemometer to measure windspeed. It is connected to an arduino with an ethernet shield. The measured data is uploaded via the shield to the server. At least that is the idea. Right now, the shield doesn't upload the data yet. Instead you connect to the webserver on the shield. After the server and network workshop, uploading to the server should be possible. For now it is possible to connect to one of the anemometers at OKNO to get its reading : open …

source: We use the Ethernet shield on an Arduino Duemilanove for testing. The Ethernet library does the trick, we just print raw JSON-formatted strings over a TCP connection and TAK accepts it fine.

Required things for TAKserver: *java *openfire xmpp server *mysql database install java; For installing OpenFire on Debian Squeeze with the .deb from ignite we need to install Java on the machine. The deb package only accepts the Sun JRE, which is debian non free. So, add non-free to your /etc/apt/sources.list, should look like this:

TAK-Server is based on XMPP protocoll so the easeast way to get started with Processing is to use jabberlib, a XMPP library for Processing. Installation Install Processing and the libraries OSCP5 and jabberlib. Your folder structure must be like that:

Working meetings Every Wednesday, 16:00 on freenode.net #tik Needed pre-info TAK server und json protokoll (updated!) some info on MACs of Clocks XEP-0060: Publish-Subscribe Server Requirements Browsers don't support a built-in support for XMPP protocol. However you can tunnel XMPP sessions over HTTP connections using HTTP long polling. XMPP server (Openfire in our case) has a built-in support for HTTP-managed connections called BOSH (Bidirectional streams Over Synchronous HTTP).

This small model is based on a design by Ed Lenz from The design of the ATKN windmill is also based on this model. You can find schematics for the design on And a sketchup file i made for a small design, here

This clock is based upon a model designed by Leonardo Da Vinci. Take a look here for an collection of historical anemometers : The idea was to use a device that has a different approach to measuring windspeed. Instead of measuring rotation, we measure the movement of the pendulum in the design.

Thu, 27 Jan 2011 12:21:53 +0200

source: So for Processing, we got started with this effort by Christian Liljedahl, which also works with our server. However, we need extra functionality, this just receives. We also use PubSub functionality in OpenFire, we need the latest Smack lib and API. Alternatively, we could format the xml messages by hand to comply to the client side protocol, but at the moment the Smack API seems nice enough.

TAK server by Erwan Erwan proposes an existing XMPP server called OpenFire in combination with Arduino's that send JSON messages and a server app calle TAK-server that handles different message streams etc. He's writing the system in Java, more info here.

Remember, we put all code on , properly link to it from this wiki when you commit something. Still something wrong there it seems... What will be running on the server An Openfire xmpp server. The TAK-server, a fancy custom thing written by Erwan that takes care of subscription to data streams etc.

As Time Inventors we have decided to invent a new time. We have to decide how to construct, share and diffuse it. This is not a light undertaking, time as we know it shapes every aspect of our daily life in one way or another. WindTime Intro Our historical time was defined by the Sun, the light it emits and the observed moving through the sky of the planetary bodies. The sun's central position in our understanding of time is superseded by what for some TimeInventors is a controversial set o…

About DIY windvanes. Different opinions, some prefer to use 360° potentiometers to measure the rotation. Others use a system with a array of reed switches. Like the circuit in this thread :
