Default Very low power dynamo (alternator actually).

So, say something new about alternators.

Just to give you something to feed on?

I don't think so.

I'll say something new...

Perhaps Larkin would be happy to address Ian's question, "What I was
wondering was whether its possible to get more energy into the battery
by letting the generator output voltage stretch its legs so to speak
and convert the excessive voltage down with a buck converter"?

How about it, JL? Address the original question with your wisdom.
Dazzle us with your brilliance. We're waiting.

...Jim Thompson

We're still waiting, though it's no surprise... push the question back
to technical details only, and Larkin enters "silent mode" :-)

Indeed.

I can't recall a single instance where he boasts about his circuits


Right, I don't boast about circuits. I do like to discuss them.

and shows his work,


How about this? It sort of evolved in some recent SED discussions.

That's more like it!

Keep up the good work.

and the board is

That's just boasting; it adds nothing to the discussion.



It's a picture of a PC board, it's not boasting. The Brat could boast,
getting all that stuff on six layers *and* getting the placement and
conduction cooling right.

Aren't the power pours pretty? I love this color graphic shapes
stuff... it's the way my brain is wired.

There's a lot of information in that image, for people who appreciate
that sort of thing.

I post all sorts of schematics, from goofy concepts to sections of
actual in-production products, like this one. And you mostly whine.


---
You call it whining because, of course, you try to trivialize any
criticism directed at you.


So stop all the clucking and talk about electronics. This isn't
Facebook or some daytime soap opera.

---

although he's certainly critical about me showing
mine.


Only when you get them wrong.


---
You don't criticize, you gloat.


That's your neurotic hypersensitivity. When you got the attenuator
values wrong, I merely pointed it out.

Check your work and you won't have to be corrected.

---

Something about that posting the math and working through the problem
is something I shouldn't be doing in order to prove that what I'm
talking about is right, mathematically, while out of the other side of
his mouth he extols the virtues of the inexactness of qualitative
exposition where _his_ "work" is concerned.
---

He'll not be heard of again in regard to this topic... except perhaps
he may toss a few snarky "old hens" or "cluck-clucks" our way.

---
That sure seems to be his wont - name-calling - when he's faced with
having to reply to anything where he has to admit to error or which
makes him feel uncomfortable because he can see it leading to where he
dare not go.
---

But he'll have no technical answer, for he has no clue.

---
Be fair.

John's a smart guy, but considers himself to be above the hoi polloi,
(anyone who isn't Phil Hobbs, whom he knows he can never rise above)


"Rise above" is meaningless. Phil and I do different things.


---
While it's lacking in your other posts, the deference in your tone
when you communicate with him makes it easy to see that you consider
yourself to be his inferior.



What is this incredible status thing you have? I like Phil, and he can
do a lot of stuff that I can't. And I do some things better than he
does. We have a heap of fun when we work on something together.

Have you read his book? It's amazing, a must-read even if you don't do
a lot of electro-optical stuff. I've given away six or eight copies by
now.
