Hi Dan,
That bread board layout is well done, neat and tidy as possible, it should be a good basis for carrying out your noise testing, { a power lines decoupling, say 22uF and 100n]

Also impressed with the tabulated noise figures results and presentation.

What's your next step?

Hey Eric,
Thanks. It took so so long. Just trimming all the wires.

The next steps are to perform the same testing without the home made cables just short wires, but I need to test with the breadboard sitting on the bench, which is what I have been dong the whole time anyway, sitting on aluminum foil, board half covered with foil, then fully covered with foil with ambient noise and introduced noise sources once again. I have to do that tomorrow as the blender and drill are a bit loud for nighttime operation.

I have pretty much written up all the work so far, but I need to also do some component reliability calculations.

The joy of it all.
