And so much! You’ll find so many crazy home-made projects. Maybe, in large projects, you’ll have some problems to find the pieces and then, when you finally get them, you realize they’re so much expensive (specially if you don’t live in UK or USA) Perhaps, if you have experience with electronics, you can replace them. Anyway, this web is a great source of knowledge and inspiration!!
