I didn't test the breadboard, since I 'know' the schematic works. I just wanted to get an idea of how all this would look on a first attempt. (The very faint/fuzzy pics in the article look like a work of art. Mine, not so much.)
I don't think the circuit is terribly complex--1 quad op-amp, 3 transistors, 22 resistors and a few caps, diodes, etc. I realize there is probably not a 'best' way, but was hoping there might be some general principles to follow. For instance, this board has 2 rows of connected holes running down the middle. I presumed it would be a good idea to use those for the multiple components that need to go to ground. Now after looking at it, I'm thinking that may not be the best use of space. I know that with my level of expertise, sometimes what seems like common sense, isn't.
Perhaps another way to ask the question is: When you go from a schematic to a board, do you just start plopping components down, from say, left to right on the schematic, and then moving them as the need arises, or do you instictively group some here and some there, connected with jumpers, or is it all simply a matter of trial and error, tempered by experience?
Thanks again.
