He wasn't actually worth that much.

Aren't you capable of grasping a concept btw ?

You mean communism? Even the kibbutz, probably the only experiment in
communism that ever actually worked [1], are giving it up.

The emotional power of music is amazing. It has an incredible ability
to make people not think. Barbara "People Who Need People" Streisand
has a rule that domestic help and hotel staff are not allowed to make
eye contact with her. Cat Stevens sang all those love-and-freedom
PeaceTrainWildWorld songs "to make as much money as fast as I possibly
could." Do you grasp that concept?
[1] because the coherent force was religion.

I think you're missing the point - the first word of the song, after all,
is "Imagine."

Can you do that? ;-)

A working class hero is something to be.

But YOU'RE STILL a fucking peasant as far as I can see.

What is it you are trying to design? Maybe we can suggest some
all electronic ways to switch the signals.

Small DC motor speed control. Switching resistors or diodes or...? to
provide
several speed choices.

12v motor pulls 2-4 amps.

Suggestions?

Thanks,
FBt

You'll need a pulse width modulator to control the motor speed yet maintain
good
torque. There are ways to create such a modulator with an LM555 timer IC.
You
use it output to control a power FET.

FDB603AL is such a FET and I found this one on an otherwise dead
motherboard.
It is rated to handle 33A at 30V with a Vgs of 4.5 volts and having a
Rds(on) of .036 ohms

I'll drop copy of a modulator that ran in Electronics Design onto
alt.binaries.schematics.electronic

it's a Word doc...

Multisourced, that's another misrepresentation. For the most part, chips
from different vendors are just similar archetectures, not "compatible"
chips insofar as actually being able to drop one in place of another. Not
to mention how vastly incompatible the code internals are for anything but
the most basic peripherals.

But that's just my opinion. ;-)

They were interchangeable when we did them Anthony! We used the same
masks to make the chips!

Well now those should be compatible. So you were making 805x true

Pretty nice specs for a $1 part, especially the Rds(on). What did it power on
the moboard?

Thanks. Without doing all the math, what R & C values would you recommend?

I found a near-identical circuit here:

http://www.discovercircuits.com/PDF-FILES/SIMPLEPWM2.pdf

Any idea what function the diodes connecting to the pwm adjustment pot
perform?

Thanks again.

Poppycock, TV ghosting is caused by multipath length differences.
Calculate the position ratio and the horizontal scan frequency
(15750 Hz is close enough). That gives you the path length
difference; it is generally on the > order of miles (= major
terrain features).
______________

Analog TV ghosts can be produced within the TV transmit antenna system as
well as by reflections of the transmitted signal in the propagation
environment. I know this from my experience as an RCA Broadcast Field
Engineer, because I've evaluated and corrected many transmit antenna systems
that had been the source of such ghosts.

For example, a reflection from a mismatch between a 1,000 foot long,
air-dielectric transmission line and the TV transmit antenna connected to it
produces a ghost with ~ 2 Âľs delay from the main image. The active scan
width of an NTSC TV line is about 53 Âľs, so 2/53 = ~4% of the width of the
screen, or maybe 5% counting overscan. This ghost is easy to see in a
typical TV set/viewing setup.

Unbeliever in gods: Show me one and I'll believe in it.

Faith: I have total faith in gravity and avoid challenging my
belief.

There is physical evidence for gravity, so a belief in gravity is not
faith.

It could suddenly stop working.

Faith is belief without evidence. This should be contrasted with
lack of proof. Proof is rarely possible in science, and is not a
requirement of science. Beliefs without proof is completely
reasonable. We just need sufficient evidence to hold a belief as a
"correct"

Beliefs without proof lead to questions of what to believe in.

But, you cant prove pretty much anything, so one justs gets on with the job
in hand.

There are mathematically proofs. That is axioms are *defined*, and based on
these definitions, results can be shown to follow. However, in he real
world, we simply cant prove that, for example, that an object will fall at
the same rate in the same gravitational field at any and every point in
space and time. We just have an enormous amount of evidence that this is so.
You can't prove the real world. However, one can often use contradiction to
disprove something. Absolute proof of the physical world, is essentially,
meaningless.

"I believe god is a blue spheroid. You believe god is a purple
cylinder. Which is correct?"

Whatever is the simplest and gives the best predictions is "correct".
Science just is not about proof, despite many claims to the contrary.
Science is about stating axioms and predicting results. Its irrelevant to
science whether or not the axioms are true in the real sense.

"The universe, is at any time, what we say it is" - James Burke - BBC Scienc
writer/presenrt/historian

e.g. http://cseclassic.ucsd.edu/~goguen/courses/275f00/Burke.html (just a
quick skim, I havnt read this page before, just know the quote)

"If this is so, then all views at all times are equally valid. There is no
metaphysical, super-ordinary, final, absolute reality. There is no special
direction to events. The universe is what we say it is. When theories
change, the universe changes. The truth is relative."

For me this should really be many views are equally valid, of course, some
views can be shown to be contradictory, hence invalid.

The poles are the armature or internal moving portion and a throw is the

So the term "throw" has nothing to do with the positions, or "stops" that you
go through when moving the actuator (handle)?

No, "stops that you go through" is exactly what "throw" means, except for
those pesky "center-off" switches.

If the pole is the source, then the throws are the destinations.

Gurus,

I need your help...

I am an amateur triathlete and I'm getting ready for the start of the
triathlon season and I had this problem last year that I'm trying to
solve.

The problem is that during an open-water triathlon swim I need to skip
a stroke every so often to lift my head out of the water and site the
next turn buoy. I usually find myself off course by a few yards and
need to make corrections. This costs me time from being off course
and from skipping a stroke. So, I had this idea to take apart an old
digital camera or picture phone and mount the camera part to the back
of my head and attach the LCD part in front of my goggles.

Sound crazy? I did a Google search and found that someone has
patented the same idea...

http://www.uspto.gov/web/patents/patog/week25/OG/html/1307-3/US07062796-20060620.html

The thing is, as far as I can tell it's never been built, and I need
your help to build it.

I took apart a digital camera and was able to power it up and get an
image on the LCD, but the LCD is connected to the camera by what looks
like a proprietary 24 wire ribbon cable and connector that I would
need to build an extension to. Any ideas if that is possible? It
would need to be about 15"-20" long to go from the back of my head to
the front of my goggles. The ribbon is about 1" now. Do you think
the picture quality would get much worse at 15"?

Another issue is that the camera has a lot of extra stuff on it that I
don't need. Do you think there is a way to trim it down to just the
ccd, lcd, a battery and a switch? Do you think a phone would be a
better starting point? I took apart a broken camera phone and I was
able to separate the pieces - but it has the same issue - a very thin
proprietary ribbon cable.

Greetings Jerry,

I imagine that you've already considered the effect of the extra drag
from the camera and display on your lap time compared to being off
course and correcting. And since you have determined that the
camera/display assembly will shorten lap times by keeping you on
course then maybe the best camera to hack would be one of the cheap
disposable digital cameras for sale at drugstores and similar places.
These cameras will certainly have as few parts as possible, and may
also be the lightest once the case is ditched. There are some cameras
with fold out displays that may have cables with fewer conductors in
order to make the swivel work. Have you thought about how well you can
focus on a display only a 1/2 inch or so away from your eyeball?
There may still be available glasses for video games that had tiny
displays in them with optics that made the image appear to be some
distance away. It could be that they used a standard video format,
like NTSC for example. If so then you could hack these and use a
cheap, tiny CMOS camera with lens and you would only need three wires.
When swimming do you get off course because of currents in the water?
Or because you pull to one side? If it's the latter maybe you could
use a timer that would beep at the rate necessary to add extra strokes
on one side or the other to train you to keep swimming straight.
Good luck,
ERS

I won't get into the character of Lennon - I didn't exactly study the guy.
But, him, the Beatles and a host of many others - regardless of their
private lives/beliefs - brought us some of the best damned music ever. Any 1
of their songs can beat hands down any dozen or so of some of the trash
music today.

Just my 2 cents for what it is/was worth.
