I've never used WW, but it seems as though it would be much easier to check lots of points with a 'scope than it is with a bread-boarded circuit. Once there are a few jumper wires dotted around the place it can hard to find somewhere to clip on a probe. Admittedly, this is without the experience necessary to know the best way to arrange common combos of ICs to optimize interconnecting them.
OT - I see Dave's or Shariah's breadboards when they demo a circuit (such a useful thing) and they're so neat and tidy. I know they obviously spend extra time on that aspect as they know it's going on YT, but even so, I don't think there IS enough time for me to get a prototype circuit to look that smart.
I really regret the 40+ years of my life spent thinking that electronics was more akin to black magic than science, and that the whole subject was "beyond me". I feel like I started a little late.
Although, I know realise that the main problem was getting explanations of basic electrical concepts from people who didn't have a scooby-doo, though they professed to be experts. Inconsistencies are bound to arise. Until coming across people like Alan (W2aew), Shariah and Dave (and the NEETS course) it seemed that most of the people who do know what they're talking about didn't start at a basic enough level for me.
