   Well I believe there's a trick or two to using the vectorboards.  I 
use the type that have no strips.  That means its all just holes and 
pads.  I do that because it allows me the most flexibility in placement 
and routing.
   My main trick is to route as much of the traces as possible without 
using wire to jump from one point to another.  What I do is take 
component lead clippings and start soldering them from pad to pad and 
snake them around the board until they connect to where I want them to 
go.  Obviously you can't really route everything there, so in the end, I 
have both "traces" and wire doing the connecting.
   Another trick is to keep all components connected to the inputs of 
things as close as possible. Of course this is something that you'd worry 
about if designing a real PCB, and certainly more important for these 
vectorboards!  It's usually the inputs that get priority as traces on the 
vectorboard and the outputs that get wires.

   The best measure against noise is supply filtering.  That and using 
reliable voltage references not based on the supply voltage!
