Do someone has a list of hackerspaces in Berlin worthy to frequent for programming / electronic projects ?

I frequented CCCB in Berlin for some time, but I didn't find the experience unpleasant for a number of reasons:

1. is more like an office space where people go to work and are not so inclined to speak with you;

2. apartheid exists there: if you aren't a member you have no access to the "hackerspace", that in truth is very small. If you are lucky, you become friend of a member and you gain access to that place, but often , because it's near to the "relax area" you have to ask the permission to literally everyone to use a drill or other instruments producing noise, plus the place is considered some kind of "secret cave" for members so they have little tolerance for your presence even if you went there for months;

3. They don't like new members, they do they can to discourage you to became one. The process is based on the endorsement of senior members that you can't meet , in matter of fact, because they rarely frequent the area open to not members plus , this is my impression they are a little bit snob ...

So at the and I was tired of that place , chasing to avoid going there further and I'm actively searching for a new place. I'm interesting in system programming ( I use C++ but I know other languages ) , security, open source, electronic, telecommunication. I'm looking for an inclusive ambient ( I'm not German ) where I can talk with people with same interest and developing hardware is viewed favorably. I have necessity to specific tools, normally I have available all I need. Every suggestion is welcome, thank you in advance.
