Most of this weekend I spend digging through some of the lightest documentation around, trying to figure out how to make a simple plasmoid in python. Took me over two days, but I finally got it done. I even wrote a tutorial on how I did it!
The fruits of my labor:

And of course, powerchart-pre0.1.plasmoid
Hi,
very cool example of a python plasmoid that works with the Soliddevice and uses the Plasma SignalPlotter class .
Another more basic example you can find here http://www.developers-blog.org/blog/default/2009/06/01/Python-Plasmoid-Example .
Have fun
Rafael
Brilliant, just what I was looking for.
I shall soon be making plasmoids in my favourite language:)
