Raspberry Pi – Fetching live meteorologic data from the web!

In version 1.0 of the paludarium, I had fetched an entire year of data, and I put that into the controlling software. That software in turn simulated that year of weather over and over again. But wouldn’t it be the coolest thing if I managed to pull the meteorologic data live from the web? With the Raspberry Pi I figured it should be possible. Todays goal was to fetch live meteorologic data from the La Selva biological station in Costa Rica. After some fighting with basic Python, I managed to get it going!

Where the data is

The data is actually freely available here: http://www.ots.ac.cr/meteoro/default.php?pestacion=2.

I found out you can build a URL that will fetch half-hour data for one entire day. As an example: Read more »

The first two hours playing with Raspberry Pi

Unbelievable what can be accomplished in only two hours. Today I finally unpacked my Raspberry Pi and started to play with it. Pretty soon I had it up and running… This is going to work out just fine 🙂

The Raspberry Pi. This will be the new brains behind the Paludarium v2.0!

I just typed up the downloads page at raspberry.org, found the tool to Read more »

Paludarium software – Need a little help here!

The old Paludarium had a kind of down-to-basics way it was controlled. It did have an application server and a webserver, but everything was very much in “nineties style”. Now I am planning to modernize everything. I want an INTERACTIVE website. An iPhone app. You name it. And I need your help – I know a lot about C and assembly, but java? REST? Spring? I wish I knew more!

How the old system works

The old system was quite simple, and as a result it worked perfectly. But also, it had a lot of limitations: No buttons on the website. No configurable graphs on the website. No search, no preview of tomorrow or look back to yesterday. This is a schematic of how it all ticked: Read more »

Real-Time statistics website has moved

Because I have launched my paluweb blog, the original page behind www.paluweb.nl had to move. You can now watch the realtime stats here: http://realtime.paluweb.nl

Have fun watching! For now the webcam is down. I might put it up again, but it is likely to return only when Pauldarium 2.0 is starting to take shape.
