Hello Brian,

Keep the dogs under control as responsible people keep their children under
control.

Even then it can still happen and we all have to use our cars carefully.
One kid didn't get injured because I was going 15mph in a 25mph zone
(the street where we live). It dashed out when the garage was opened,
zooming into the road from behind a van. Couldn't see it coming but I
never go faster on that street, for that very reason. I came to a stop
about one foot before the child.


I was once in a parking lot, and just kind of _knew_ that some kid was
going to run out in front of me, and not a second later, there came the
ball and the kid. I had already stopped.

Cheers!

What a fu**ing jerk. I asked a technical question in a technical newsgroup.
I expect a technical answer.

As to your political and ethical questions to my question, go find another
newsgroup to tell others how to live. Our little tiny community knows how to
do it, we all agree on the problem, and we're going to solve it. I'm
providing the technical know-how.

And don't tell me how to use local law enforcement or local political action
how to do it. I've spent 12 years of my life in local elective office at
the highest local levels. I don't need your unsolicited advice on how to
work the system.

Please, no more of this crap. Anybody with a source for doppler radars,
please post. Others, BUTT OUT.

Jim

Hi Jim,

I don't know if I'm going to be graciously asked to butt out, but what
do you expect to gain by an alarm that goes off when presumably some
pre-set speed is exceeded? I do know that when I was a teenager, I would
have viewed such a thing as an almost irresistible attractant.

If you want a radar-based device, get an old police radar gun, and
design an interface to a camera to photograph the licenses of the cars.
Perhaps the parents of these miscreants might enjoy seeing what their
larvae are doing with the family jitney!

Sorry about the dog. 8^(

I just wonder why you are posting to an amateur radio newsgroup ?

Your rambling about speed traps has nothing to do with amateur radio.

Back in the '60s and early '70s I did some work with Impatt and Gunn diodes,
building a little self-detecting doppler for speed sensing. However, 35
years have passed and my notebooks for that stuff are somewhere in a dusty
archive along with my venerable sliderule.

Is there a cheap source for onesies-twosies of a radar front-end that will
give me doppler audio as a function of a large metal object's speed at a
range of 20 meters or so? I don't need to go into production on this thing,
just build one. A surplus source would be ideal.

It seems that the little kids on our rural country lane have all become
teenagers at once and are trying to outdo the others in how fast they can
drive daddy's car up and down the lane. We've lost one dog this week and
unless I can put up some sort of a siren that goes off when they exceed some
agreed upon limit, the carnage will continue.


Regards,


Jim



IIRC I've seen police radar guns as surplus.

It's been quite a few years ago now, so I don't recall the details,
but I bought a "sports gun" for my youngest that he used at dragster
events. I think it was about $100.

no offense but:

ramsey's kiit emits all of about 500 microwatts at 1.6 ghz, useless
for dogs, but Ok for part 15 radar of cars.

Do a looksie on E-Pay, cheap old style X and K band units are available.
With a 12vDC power supply, you can have your very own source. Even if you
just buy the head without the counter, the 12vdc will supply the head and it
will put out.

Do NOT purchase the Ramsey "kit" for this applicaiton. While it may be fun
for a budding electronics wanna-be, it does not put out at a frequency that
will trigger radar detectors.
