Links

There are various people around the world who have excellent link lists related to the automata subject.
My favourite is the Swiss one of 'Kugelbahn':

www.kugelbahn.ch

There are three major blogs related to automata where I regularly take a look:

Falk Keuten (German blog): www.kugelbahn.blog.de

Phil Sing (France): http://manivelles.unblog.fr/

Dug North (USA): http://blog.dugnorth.com/

I didn't find an English blog with regulars entries yet, but I suppose English people concentrate more on making automata than talking about.

There is also an community on Facebook, look for 'Mechanical adventures'.

Last but not least the Crankahead Facebook group:
