[OSM-talk] Never run out of batteries again!

[Patrick Weber]

German C't Magazine had an article a couple of months ago about how to 
keep a PDA/GPS charged with a hub dynamo while cycling. They basically 
showed you how to construct a buffer battery and electronics for it, 
that can fit into the seat tube. I dont know if there a English 
translation, the article unfortunately is paying.
