That's like 15% of fatal road accidents involve a drunk driver. So surely it's

Yes - audio requires a constant data stream - or it'll cut out. You simply
can't get any decent kind of audio quality over Bluetooth - 732 kbits/sec
is
the max flat out without other devices contending. CD audio is just over
1.4Mbits sec for comparison without 'handshaking'.
You'll get m p3 quality over Bluetooth I guess.

732kbps is plenty for compressed audio. You know that cell phones get away
with something like 2.4kbps for their CODECs? 128MBps MP3 compression much
better fidelity than, e.g., FM radio. While MP3 (and cell phone CODECs)
require a significant amount of processing horsepower to
compress/uncompress, even simple compression schemes do OK with a could
hundred kbps.

You think you need a focused beam to solve some design problem. I think
we can assume that just running a wire for 50 feet is not in the cards.

If you go with electro-magnetics:

If you wind a coil onto a large rod core, you can get more of the power to
go in the desired direction than at right angles to it. This will be
about the best you can do with anything smaller than, lets say, 50 feet

You could change to using sound: 25KHz is high enough that most people

Why is it you think that I don't want an answer?

There is little motivation for you to know how I feel. Frankly, again,

there is serious problem on the left where they are consiously sewing the
seeds of hatred. Kerry's advocates (who help to propagate the hate)
are being more cruel against the new advocates than against Bush. New
people are being infected with the diseased thinking for crass political
purposes, and those who are knowingly passing the hate-disease
onto others are showing ethical/moral depravity (or are so diseased that
they have little self control.)

Those most damaged by the hate speech are those who are vulnerable to
the hate as participants. People looking at it from the outside (like me),
might feel disgust, worry, concern, pity or many other feelings about those so
very afflicted. Perhaps those who are 'religious' might even perceive
the seeds of evil or satan being propagated by the Bush hatred. I
don't manifest those kinds of thoughts, but do see destructive tendancies
in the afflicted. Much like VD, the hate being passed around in Democrat
circles does show a lack of respect for others.

Perhaps the cruel and poetic justice is that those who were so very critical
against those who couldn't love Clinton because of his childish, emotionally
incompetent behavior (and in fact, illegal actions wrt court testimony),
have themselves actually fallen prey to the hate. It hasn't been those who
simply couldn't accept Clintons' poor behavior who fell prey to hatred. Most
interestingly, some of the out-of-control pro-Democrat hate-mongers will be
paying an emotional price for their support of the very lousy traitor
against America, John Kerry. Even though he is a dispicable person, I just
don't have any strong emotions about him (other than dismissal.) With a
complete set of adult
emotions, it just doesn't make any sense to waste any consiousness on such
human debris. If John Kerry did become president, it JUST MIGHT be time
for even those who are non-religious to pray for some divinity to deliver
us from John Kerry, who would be (at least partially) elected based upon
'evil and destructive hatred.'

On the other hand, the strong, almost unconditional Bush supporters seem
not to have an equivalent emotionally incompetent hatred as manifest by
the overly strong Kerry supporters. The Bush supporters SEEM to be more
fearful of the previous (and in some respects, almost current) traitorous
behavior as manifest by John Kerry. So, from the Bush side, it seems that
those advocates probably see Kerry as inappropriate.

From the center (who would actually possibly be convinced of voting
for Kerry, IF he wasn't a traitor), I see both sides as being irritatingly
religious. The reflexive excuses for Bush's poor performance under
certain circumstances, or the prominant emotionally incompetent Bush hatred
espoused by Kerry supporters are both 'irritating', but perhaps with the
hate-emotion as not just irritating but also being a probable indicator
of true mental illness. More often than not, the Kerry supporters seem
to be more involved with Bush hatred than Kerry love. Frankly, both kinds
of emotions (mental illness as being indicated by misplaced hatred, or
loving a traitor) show a kind of incompetency that disappoints me, and
even makes me pity the twisted person for their pathetic life (from their
limited set of thinking tools.)

Interesting that you should talk about pulling "finding" from bad
businesses, because that is exactly what William C. Thompson, New York
City Comptroller decided to do with investments in Halliburton- and
specifically because of their dealings with State Sponsors of Terrorism
like Syria, Libya, Iran, Iraq, and the Sudan. Many prominent investment
groups have pulled the plug on Halliburton stocks and a few other
businesses. And this is not just a "liberal" slant- it is integrity-
these people know exactly how to investigate and assess an illegal and
immoral involvement, and unlike the DoJ and a criminal standard of
proof- the exercise of integrity is driven by a reasonably probable
cause. It is the height of hypocrisy and fraud that the vice president
of the US should have any connection with a company like that, and in
these times under these circumstances; or that the administration should
have made them a major contractor in Iraq under any circumstances:
http://www.cbsnews.com/stories/2004/01/22/60minutes/main595214.shtml
It is quite revealing that GW Bush wants to wage war on terrorism up to
the point and short of interfering with US business dealings- then he
backs off. The idiot must think that war exclusively means application
of military force. This is just the tip of the iceberg of their
stupidity- the US is going to pay dearly with an attack on the homeland
in the near future.

One of John Kerry's claims to the White House is that his diplomacy

the centerpiece of Mr. Kerry's arms-control offer to the mullahs.

We'll just let WSJ stick with their business news and leave the
international security assessments alone. It is Bush's truculence that
has induced N.Korea and Iran to accelerate their weapons programs and
designs for WMDs- how else could they hope to repel an invasion by this
international law breaking US with a lunatic at the helm. You can take
every single one of Bush's rationalizations for invading Iraq and apply
them x10 to Pakistan- but then they have nukes- so there's another "no

Ah CAMCORDER! Now I understand the reluctance to modify.
You may have said that before, I've been rather under the weather this
weekend, I may have missed it.

This is why the subject line said "revisited". I asked some questions
about this project in its initial incarnation a while ago. At that time
it was purely for camcorder use.

The original project - and it's going up on my web site soon, I promise-
was either:

a) to store telemetry data on the audio track of a camcorder,
synchronized with the image, or

b) to devise some reasonably solid method for putting sync marks onto
the videotape, so that a (flash or HDD-based) log could be
cross-referenced to the video stream.

The design restriction is: minimum possible reverse-engineering of the
cameras in use. It's acceptable to put a few patch wires into the
switches and buttons so they can be controlled remotely. It's NOT
acceptable to reverse-engineer any part of the analog or digital signal
paths inside the device and tap in anywhere, since there's no guarantee
that any particular tap-point will be available in a different model of
camera.

The circuit controls either a camcorder or a digital still camera (DSC)
over either async serial or SPI. For example, in powerdown mode it
disconnects the main power input to the camcorder. When the vehicle's
main controller requests it to start recording, it:

* applies power to the camcorder's battery terminals
* activates outputs that set the camera's mode switch to "record"
* "presses" the record button
* monitors the REC LED and signals back to the host if that LED goes out
(which signifies end-of-tape).

It can do similar tricks with a DSC. Someone pointed out to me that the
DSC control functions would be even more useful if there was a way of
recording the telemetry stream (since it's being sent out anyway, may as
well use it). Audio cassettes are by far the best and easiest way of
doing this. So that's why I'm looking at the problem. Seems like I have
it almost solved.

Well, if you do not mind what internal voltages are, or what the
circuit looks like (meaning what discretes are used), one might try
using 1000V FETs for the output stage (IRFBG20) for starters.

I've already gone with the high voltage MOSFETs elsewhere in the design.
Making a circuit that will output the 0.25A and won't fry the MOSFETs
proved to be a bit trickier than the lower current outputs. Even if the
circuit holds to 0.25A thats a peak power of 150W. The shut off can't be
thermal in that case since the smoke will leak out of the MOSFET before
enough external rise is seen.

FET; just make sure the power rating of the resistors is at least double
calculated power at 150V each.
That results in a driver that is bigger than the whole product. We end up

with trying to loose 150W out of it.

Hi,

On Wed, 16 Mar 2005 08:30:46 +0000, Rikard Bosnjakovic wrote:

Greetings

As a newcomer to the wonderful world of electronics, I have recently
setup a minor electronics lab in my home and started to build a few
things. My tools and equipment exists of standard components (resistors,
capacitors, ICs, etc), soldering iron, a bunch of veroboards and a
multimeter. I do not, however, own an oscillator or any of those more
expensive tools like PCB-etching equipment and such. Atleast not yet.

I don't think it's necessary to own PCB manufacturing gear. If veroboard
is not suitable you can have PCBs made reasonably cheaply.

Olimex [www.olimex.com] make PCBs very cheaply and seem to do a good job.

Keep in mind that most home-made boards are single-sided or double sided
without through-hole plating. This limits their usefulness quite
significantly.

As stated above, I'm using veroboards (stripboard and breadboard is a
synonyme for the same thing, i think) for building my circuits.

In my experience "stripboard" and "veroboard" mean the same thing. The
term "breadboard" usually refers to a plastic board with an arrangment of
holes into which components and wires can be plugged (no soldering).
Breadboards are used for testing circuits before final construction.

I also
own a licence of Electronic Workbench (Multisim and Ultiboard are the
ones I use most frequently). However, since I do not own any etching
equipment Ultiboard is of less use for me since it can only do
PCB-layout/routing. I have contacted the developers to hear if there was
any possibility to make Ultiboard output to veroboards, but regretfully
enough UB is designed for PCB only, was the answer.

I haven't used electronics workbench, so I won't comment on it. If you
want to simulate circuits cheaply you might want to look at LTspice
[www.linear.com/software].

1. Is there any layout/routing-application that is able to output
layouts for veroboards? I have only found two cheap shareware-programs
on Google. Even if they work, they were terribly tedious to use (limited
amount of components etc). Is there no commercial or fully developed
program anywhere? A great plus would be if the program could read the
format that Multisim saves to, thus allowing me to save time by not
designing the whole circuit all over.

I find that the best way to do veroboard layout is by hand using a large
section of veroboard, the components you intend to use, and of
course your schematic.

When plan a component layout you need to worry about grounding, mounting
decoupling capacitors close to the components which need them, adequacy of
power supply rails and many other issues. I really doubt that any CAD
package will do a better job than a person.

2. When constructing on veroboards, I often have the need in cutting the
boards to smaller shapes and I've found that it's pretty cumbersome
since I haven't found any good tips of how to do it the right way. For
new boards, I could take a small saw and shape it up without much
problems. But for new circuits that I haven't done before, cutting the
boards could lead to a too small board in the end, requiring me to start
it all over again.

The best way of cutting veroboard (I assume you mean the stuff with a 0.1"
hole matrix drilled in it) that I have found is to score it along one of
the rows of holes with a sharp blade and then snap it.

Sometimes it can be useful to initiate the break using sidecutters on one
end of the score line.

The break edge can be cleaned up with a file.

It is reasonably safe to cut the board with components in place. This
avoids having to guess the board size ahead of time.

Regards,
Alan

The characteristic impedance of a transmission line is *only* the value

For other loads, the input impedance wil *not* be given only by its

This simply isn't so. The impedance of the transmission line does not

change in response to the load on the end of it. What does change is
the impedance of the entire *network* as seen by the source. This will
be the load impedance rotated and transformed by the line
characteristics. To understand this in a reasonably intuitive manner,
get hold of a book on Smith charts.
