I am in need of how exactly to build a transmitter @ 20hz-1KHZ at a
high enough wattage to overcome/overload a simple stereo speaker.
Yes I did mean 20 HERTZ to One Kilo-Hertz.

I have a couple of hundred dollars to spend on this project and also
have a lot of free time these days on my hands.

As far as a electrical power source I have up to the 110 volts coming
into my home as a source and as low as a 1.5 volt battery. I also have
a power supply that mimics a standard car battery's 12 volts of power.

Can one of you get me started with the basics so that I can eventually
build such a device?

It's not for a job or college project and it is simply my need to
understand and learn this concept if possible.

I do know how to read simple, very simple, schematics.

Another Thing: I used a computer program many years ago that simulated
a very simple circuit to check for faults and errors. Does such a
program exist today in the Windows environment for simple designs
which is free or nearly free to troubleshoot the project to save as
much money as possible? I'd hate to spend $100 on parts and have it
blow up just because I made some rookie mistake if you understand what
I mean?

thanks

Robert,
Could you explain what you mean by "transmitter" in this context, and also
what you mean by "overcome/overload".
20 Hz to 1KHz is only going to get into the speaker through wires. (barring
extreme magnetic energy to pull the cone out at 100 yards )

Why does humility matter? What matters is the fortunes and lives of
the least fortunate in the world. This isn't some political game for

IMO, becuase humility helps both an individual, and a nation, to approach
others as valued equals rather than as underlings.

The Europeans have more than enough humility to go around. It takes a
good deal of arrogance to believe that you can and should change the
world, and Lord knows, the world needs some changing.

John

I think that the semantic of "humility" is the only differnc Ihave with
your statement - looking up the definitions...

OK, it's messy -
:The quality or condition of being humble.:
humˇble (hmbl)
adj. humˇbler, humˇblest
1. Marked by meekness or modesty in behavior, attitude, or spirit; not
arrogant or prideful.
2. Showing deferential or submissive respect: a humble apology.
3. Low in rank, quality, or station; unpretentious or lowly: a humble
cottage.
tr.v. humˇbled, humˇbling, humˇbles
1. To curtail or destroy the pride of; humiliate.
2. To cause to be meek or modest in spirit.
3. To give a lower condition or station to; abase. See Synonyms at
'degrade'.

What I'm thinking of is: "not arrogant or prideful".

I don't think that it requires arrogance to believe one can/should change
the world. It's *common*, but unnecessary.

I think that what would be an example of arrogance is insisting that the
entire world be exactly like oneself, becasue one believes everyone else to
be inferior or "less human".

I think an example of non-arrogance is to want to change the world becasue
one believes in encouraging the best aspects of Human potential and wants
to reduce human suffering, even if only in some small way.

I find that VHF SSB signals are good at doing that. Much, much, much easier
to construct antennas that concentrate their output in a fixed direction at
those frequencies as well. A couple hundred watts and a 12dBi yagi antenna
and you should be set. One more thing, you'll need to obtain a federal
license to do this.

Warning from Pakistan

This morning, from a cave somewhere in Pakistan, Taliban Minister of
Migration, Mohammed Omar, warned the United States that if military
action against Iraq continues, Taliban authorities will cut off
America 's supply of convenience store managers and possibly Democrat
candidates for President of the United States .

And if this action does not yield sufficient results, cab drivers will
be next, followed by Dell and AOL customer service reps, and then
Motel 6 managers.

It's gonna get ugly .. folks!

The LynxTwo runs neck-and-neck with an AP System 2,
according to its designer who of course has one.

So not actually 'better' then ?

Testing a LynxTwo with an AP2 won't give an answer either way, for obvious
reasons.

I seem to remember that the designer said that my www.pcavtech.com results
for the LynxTwo were significantly better than what he got while measuring
it with an AP2.

Hi there - I was just looking at a datasheet for some CCFL
transformers (http://www.cooperbussmann.com/pdf/dc8ad71f-
f3ce-4c72-8bfd-5d8373663c5b.pdf) and noticed that the secondary coils
on some are labeled as floating, while others are labeled as fixed
(see middle of page 2, schematic a and schematic b).

What exactly does this mean?

** Email the company and ask them - as they seem to have invented their
own term for the design.

The "floating" and "fixed" secondary versions vary only in pin out, as far
as the specs indicate.

So, is this a neighbor that has the volume to loud for you?
Mike



No it's those loud bass thumping stereos from cars that drive by, also
the same system for people who live 2 houses away from me.

I have nothing against loud music but this is literally shaking the
entire house, you can feel it deep into your own body. I don't think
that's fair so I'd like to see how they would feel.

If it's ok for them to interfere with me then they should be willing
to let me do the same thing.

As an anti-doof-doof measure what would happen if the incoming doof was fed
via a microphone and low pass filter to a threshold circuit. If the doof
exceeds a the set threshold delay the original recieved doof signal ( xx
milliseconds), amplify it and send it back via a sub-woofer of your own.

They turn it down - the feedback stops....

What would it sound like for the source - unpleasant?

Then what do you call my dozen or so neighbors who think it's ok to

Are you saying that your neighbours, whose homes must be similarly

I think thig guys setup leaks microwave RF and somehow this provides the
microscopic thrust he is measuring, or maybe the air inside heats up and leaks
generating thrust.

He himself mentions EMI problems with his camera so clearly there is some RF leaking.
So much for a demonstration.

What's amazing is that he managed to convince the idiots in British gov. to finance this crap.

I wouldn't say they exactly "equal" the US in space capability after one

be more impressed when they leave orbit.

Neither space walks, no putting men on the moon, is inherently
valuable. And nowadays, with so much technology behind us, neither
is especially difficult; all it takes is a heap of money.

What might well be inherently valuable is doing a bit of asteroid
mining.

Do asteroids have any valuable stuff inside? Seems like even a solid
gold asteriod wouldn't be worth the energy it would take to exploit
it.

It's not worth it if you intend to bring the stuff home. But it's
unimaginably valuable if it's to be used in space. The same energy
costs apply to getting stuff from here to space, so raw materials
that are already there are inherently valuable.

And it sure wouldn't make sense to send up people to do it.

Agreed.
