John, I really don't see why you're arging this point.

Because he is under the mistaken impression that he is an engineer.
A real engineer has the all-impotant attribute of listening to what
people tell him. You can tell Larkin how lifters work and explain
that the only reason they have wires going to them is because the
power supply is too heavy to lift all day, but it won't get you
anything but questions and - eventually - personal abuse. Ignore
him.

Have you calculated whether a big stack of coin cells driving a
DC-AC inverter and then a Cockroft-Walton stack will be light
enough to fly yet? what number are you getting?


The "thin nylon wires" are used to hold the lifter in place so it
won't fly away. They are not the conducting wires for the power
supply. Lots of amateurs have made lifters with no tethers: they
usually fly up far enough to disconnect the power supply wires or
damage the lifter. There are many web sites online discussing the
lifters which you can find by Googling. You can write the authors
of these web pages if you don't believe how they work.

You are wasting your time explaining. Usenet being what it is,
I strongly advise you to look at how helpful each person who
responds to you is and to not reply to the non-helpful. I even
wrote up a nice explanation of how this works so folks can quote
it. Here it is:

---
"I even"...? Just more of your narcissitic bullshit, Macon.

THE STANDARD ADVICE:

There is a way to influence what gets discussed in a newsgroup that
works well, and another way that has never worked no matter how many
people have tried it.

What works: Post articles on the topic you wish to see discussed,
and participate in the resulting discussion. Use killfiles and
filters so that you don't see the articles that you dislike.
If you don't know how to use a killfile, use good old fashioned
discipline and don't read the articles that you dislike.

---
Geez, how do you expect to know whether you'll like them or not unless
you read them? Just another of your badly thought out schemes which
you offer as the infallible "Macon's way".
---

Never, ever respond to articles that you dislike.

---
See above.
---

What doesn't work: Respond to articles that you dislike, complain
about articles that you dislike, complain about posters that you
dislike, complain about how terrible everyone else is for not posting
what you want them to post. Talk about how to respond to articles
that you dislike. Make the articles that you dislike the center of
attention, the main topic of discussion, and a personal crusade.

---
I've seen you not take your own advice on that, so you're advising "Do
as I say, not as I do."?

Also, what I've seen you use killfiles for is mainly to get the last
word in and not have to pay attention to rebuttals. Burying your head
in the sand, of course, so _your_ reality is the only one which exists
and you don't have to admit error to those you don't like.

The funny part is that the same search criteria on Google can and will

least in the order of importance...if I am not mistaken.

Such a coincidence: the very first search pulls up

You may have overestimated the search engine,

For example, If you Google "poor to nonexistent" engineer:

Yes, agreed. But to be taken more as a very well-earned and
well-deserved compliment to John than a slam to Guy. Frankly
I wonder if Guy has acquainted himself with John's technical
accomplishments as they've been detailed here in the last few
years. And to John's revelations about the SF cultural scene.
Perhaps Guy's been completely oblivious to it all.

In case there is any doubt, here is one possible scenario when
performing a search for the following:

any serious critique, and we may
{see guy flame the engineer} (also number 1)

I find the psychology of design to be fascinating, and too little
studied.

Arrogance: On one day, you have to stand in front of a bunch of
customers or fellow engineers and state calmly and confidently that
you can certainly fit 16 channels of whatever ghastly thing onto a 6U
Eurocard, meet insane specs, and deliver in three months for $200 a
channel.

Discipline: now you have to design it, manage all the tradeoffs, cram
it onto the board, and not screw up, because there's no time for a
respin.

Fear and paranoia: after it's on paper, and you're about to etch
boards, you have to question the sanity and competance of the morons
who designed it; you just know that these guys made a half-dozen
stupid, fatal mistakes.

Despair: when you occasionally do find a fatal mistake, and before you
come up with a work-around.


One key to success is to accurately gauge one's own incompetance, and
to take carefully calibrated risks in only the situations that demand
it.

Suppose you had a light, high-voltage, high-current power supply. You

John

This page shows construction of a lifter:

How to build an HexaLifter for your experiments.
http://jlnlabs.imars.com/lifters/hexalifter/index.htm

One lead from the power supply is connected to wires at the top of the
lifter. The other lead is connected to metal foil at the bottom. You
have insulators separating the wires from the foil. Then the air
between the wires and foil serves as a dielectric for a capacitor. The
asymmetric geometry of the two sides of the capacitor, the wires
compared to the flat metal foil, causes a flow of ions from one to the
other.


Bob Clark


But that's not the way the hexalifter is wired. External (grounded)
+HV is run through a wire from the power supply to the upper wire
array, and no connection is made to the foil thingie.

If you did make an unthethered lifter, with no return current path to
ground, its ion emission would quickly build up a huge net potential
on the whole structure. Has anybody ever got this to work?

There's a much more efficient way to convert electrical energy to
lift; a helicopter rotor.

John

Perhaps the second wire connection is not visible on that page, but
all lifters are made in this same way. See for example this page:


The hexlifter page says that one wire supplies hv to the lifter's
upper wire array, and that it "is maintained with three thin nylon
wires to the styrofoam base plate" which doesn't sound conductive to
me.

So the single uplink wire replentishes the charge lost by creating
ions. If you float the power supply onboard, and still eject ions, a
huge charge will quickly build up on the structure.

Has anybody ever built a self-powered, unthethered lifter?

John

John, I really don't see why you're arging this point.

Because I'm an engineer.

The "thin nylon
wires" are used to hold the lifter in place so it won't fly away. They
are not the conducting wires for the power supply. Lots of amateurs
have made lifters with no tethers: they usually fly up far enough to
disconnect the power supply wires or damage the lifter.

But can they fly with *no* wires?

Yeah, it's sounding to me like, "Put up or shut up" time. Hell, if

I'm allowed to use an extension cord, I can fly a fuckin Muffin fan. ;-)

I loved those old ADM-3 Dumb Terminals.

Kindred spirits?

You wish! ;-) ;-) ;-)

I've built a dumb terminal. Kinda like the "TV Typewriter". Hey,
didn't Don Lancaster write that TV Typewriter article? I was
so frickin' proud of myself, because I pipelined the character
ROM. ;-) IIRC, my "dumb" terminal had a uP in it, just to
initialize the video sync generator, and manage shuttling
characters from the input to the screen. It might have been
a Z-80; I don't specifically remember which uP it was - it might
have been a Motorola - it was so long ago. *-) - except that I _do_
remember that my keyboard thing used a 6502. I had got a naked, raw
keyboard at some swap meet - each key had two terminals sticking out of
the plastic behind it. 64 (or so) individual SPST switches; and I
had a passel of uPs and RAMs and stuff, because I was working at
the video game place where they'd bring in an obsolete video game,
and for about a tenth the price of a new game, they'd refurb
the cabinet, and swap out the board with a 'Mr. Do!'. They
tossed the OE board. Everything from Asteroids to Space Invaders
to games nobody's even ever heard of - I had dozens of discarded,
but still fully functional, video game boards. This is a PCB
about the footprint of a PC Motherboard.

Sigh, those were the days.

I also once as a programming exercise, wrote a dumb terminal.
I admit, I used CodeView, the popup debugger, to steal somebody
else's COM port interrupt handler, but the rest of it was a
piece of cake. ;-)

Cheers!
