Due to my soldering snafu (described in gory detail else-thread) I came to be needing a new board for my "$50 robot". I went to radio shack and they don't seem to have the same board - check the web and no luck there either. They still have a 371 pin board, however, whereas in the guide it is listed as '276-149' what is now offered is '276-149a'. The difference, from what I can tell, is sets of 3 pin holes have copper across them.
My question is whether I can use this board the same as the last board, or if that copper on the back end means I'll be getting funny shorts all over the place - not sure what the purpose of that copper is other than to provide a soldering surface. If I can't use the new board, any thoughts on another board to use for the "$50 robot"? I did find a much larger board that doesn't have the running copper connections all over the place but wanted to avoid it if I could as it would be rather clunky on top of the robot for this particular project.
Appreciate the help.
