So if I got u right,, the design is complete but the problems are in the implementation only? I should give it a try then, and anyway any prototype would be built with air wires before pcb implementaion, if only air wires are the problem then that can be overcome. But why cant the regular scope probs be used?

 

 

A last thig, will u please arrange ure technotes site better than it is now, why dont u make it that when u go to the page u find a list of all possible technotes instead of the current design that doesnt show what are the currently available technotes?
