In a stripboard the blue layer must be implemented on both sides (because the strips are one way.) This leaves us with a situation that if the red layer overlaps the blue layer and if the blue layer needs to be implemented on top(the other direction to the strips) we get an impossibility. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
