Re: Using "Conductive Pen" for drawing traces

2007-07-15 by Jim

Hello,

Forth the sentiment.  I'm not even sure how you could solder 
components to the conductive ink...  Disappointment awaits you on 
this path I think.

Point to point is a much better way to go.  Have you tried a 
prototype board?  Take a look at radio shack part #276-168.  You can 
solder your parts to the board and use hook up wire for the 
connections.  The nice thing about this particular kind of board is 
that you can easily replace parts and jumpers without too much 
trouble.  Kind of a hybrid PC board.  I've used boards like this for 
quicky one-time projects and have had great success.  Vector makes 
similar products, but they are unreasonablly expensive IMHO.
