Yeah, I kinda figured that out on my own, thanks. I just felt it would be
prudent to point out that I am not one of those people, so that I wouldn’t be
the subject of false assumptions. Well, no more than usual, at least...

The electrical stuff is just a way to get trains to do their thing, in my
view and hence, less interesting. Others DO find this interesting and have
done a lot of actual research and documentation to advance the hobby which I
for one am very grateful for.

Considering how little overlap there seems to be between hard-core Train AFOLs
and people with lots of electrical experience, I’d think you’d be less
dismissive of any input provided by people with electrical experience even if
they aren’t as interested in the trains as they are in the electrical problems.
Oh wait, that’s right. None of my experience counts in your eyes unless I
provide specific details:
1. I helped rewire about half of a friend’s house during college
2. I spent two years working on the college theatre’s light crew, dealing with
50 and 100 amp circuits and 500-100 watt fixtures, and often custom-building
“practicals” (with both serial and parallel wiring) into the sets themselves. 3.
I provided the lighting design for two plays, including laying out the circuit
hookups and drafting the light plots. 4. I spent most of my summers working for
the college maintenance department, often fixing electrical fixtures in both
120v and 240v systems. 5. I’ve rewired a 3-phase vac pump and a 3-phase 7.5hp
table saw motor. 6. I rewired a CNC to 5-axis capability, even though the
control system can only handle four axes (and the only major problem there was
that my boss ordered the wrong relay switch).

But I’m not sure idle speculation by the uninformed is all that useful,
really.
|
How very fortunate that I am genuinely interested in solving this puzzle, and,
thanks in part to your overly-technical explanation and in part to the fact that
I’m a very quick study, I am no longer “uninformed”...
| |
That said, the electrical puzzle IS touched on by the reversing loop
writeups I suggested you seek out, but I guess you wouldn’t know that since
you apparently didn’t do so.
|
It was after 1am when I got started and I wasn’t going to spend hours doing
research at that time of night. Besides, I figured it was a safe bet that if
even you hadn’t seen Ville’s idea used before, it probably wasn’t directly
covered by any of these writeups you alluded to, and I was able to glean enough
information from other posts in the thread that it seemed irrelevent to the
problem at hand.
| |
It’s easy enough to discount this possibility if you just do a little
research(1) before you start speculating. There are a number of disassembly
photo series out there that make LEGO train motor internals quite clear.
|
That’s not relevent to the idea I proposed, and you know it.
...thereby ignoring the main point of the post. I drew you a couple of
pictures, so my explanation will be easier to understand:
Maybe they’ll manage to catch your eye a little easier before you can snip them
away in your reply...
