thank-you! Great step towards what I'm looking for 
As the boards I've shown are verry cheap, double sided and aviable from differnt sources (ebay, aliexpress etc) it might be worth the effort to alter the Basic-Single-Sided Perfoboardsto to fit the "real existing ones" .
Being a newbie I'm not / feeling not able to take this task 
(Found horrible stories about creating / changing fritzing parts ...)
Thanks!
