WAAAAAHHH!!! Do tell.
Would these be broadcasting continously? If so, wouldn't reflections cause
the V1 to be constantly going off?
Alternatively, would one wire it up to the V1 so that it broadcasts only
when a laser warning is given? What would be the advantage of doing it this
way? Since the LEDs are so cheap, why aren't we all running 16 of them
surrounding our front plates, constantly emitting??
In other words, if it was this easy, why aren't folks selling simple,
always-on jammers for $100?

OK, being a Mech E., I jsut hit up my EE counterpart, who dug up a 16

I just found the perfect xmas present for my better half :)
Pictures to follow after the holidays... of the install that is.
THANKS FOR THE IDEA!

Ah, fair enough! But in the greater scheme of things, if this really is
that cheap and easy, we should ALL be running the jammers and turning off
the laser detection on the V1! :-)
Seriously, in terms of effective counter measures, wouldn't a constant
emission have a better chance of defeating the laser gun?

You guys seem to be overlooking one thing. In the eyes of the court, a
police officer's estimate of your speed is considered the testimony of a
trained professional and therefore admissable. So even if your
super-keeno-dweebazoid laser jammer throws off his reading, all he has to do
is testify that he esitmated your speed to be whatever. Unless you hire a
good attorney (which I might consider for a triple digit offense), you're
going down.

But... Even a not so good attorney can probably argue that if the cop is
staring through a telescopic sight on a laser gun, he can't possibly be
able to accurately estimate that vehicle's speed visually.
That'd be my defense, anyway. As someone who's been trained to estimate
distance and speed for much more lethal reasons, I might be able to put
up a good fight if I managed to get one of the 4 honest judges in the
country.

Not where I practice law . . .
Here in Maryland, the officer is trained to estimate speed first, check
second, but his estimate is simply that, an estimate.

OK, I'm going to crack the V1 and use THAT as my "instant on" for the LEDs...
Using a relay (so as not to toast the V1) to turn on the power to the LEDs...
With a 1K ohm or so resistor to to limit max current based on the LEDs...
Here's the LEDs I'm using (901nm)
http://www.ledtronics.com/ds/sml10ir941t/default.asp
L120CWIR881
Everything will be benchtested BEFORE fires or fried german electronics ensue ;)
(the joy of having 2 V1s in the house for each driver :)
If everything works out, an FDM ABS model will be used for the LED
enclosures... me thinks tucking them just under the E46 headlights might work,
but I need to poke around and see where those 4 clusters of 4 might need to go!
Plans will be sold cheap :)
(Supply your own V1s though!)

I imagine you also could reverse-engineer the V1 remote display and get
some kind of trigger from that instead of opening up the V1 itself.
Valentine might even provide documentation for the remote display port.

Or make a style statement. How about a license plate frame with the LEDs
built in? Or for a more stealth application, buy a cheap auxillary driving
light, remove the guts and put the LEDs in the case.

Message-ID: <[EMAIL PROTECTED]>
Actually, my understanding is that a combination of the following will reduce
the effective range at which a cop can get you with laser
- blinder or some other active jamming device-
- "Veil" - some sort of translucent coating you put on the front and rear of
your car (or whereever you think they aim laser at)
- Not having a silver car
- Not having a highly-reflective front license plate
Any of the above countermeasures will reduce the ability of a laser to get a
fix on your speed.. in some cases the effective distance can be reduced by a
factor of 10. If your V1 is going off at 10x and the cop cant get a read until
x, you've got 9x to slow to an acceptable speed and disable your blinder
(assuming its not automatic)
So laser detection is still helpful, especially if you've got an assymetric
setup where you can detect them before they can get a fix on you.

What beam spread? Packed how closely together? Are there specs for
what kind of overall IR field is needed for effective jamming? IR LEDs
come from ~120 degrees down to 15, with increasing intensity as the beam
narrows. There are also little reflectors available in single led size.

Message-ID: <[EMAIL PROTECTED]>
Hi!
I have 97' 540i/6 with 170k miles. It has oil leak that starts getting worse
with time. I see puddle of oil about 4 inches in diameter after every night in
garage.
Today I inspected everything with a mirror and it seem to be that upper covers
leaking oil. I replaced leaking Valve covers 2 years ago and they look good.
So.. I need word of wisdom on this new problem. According to Bentley since I'm
not going to touch chains - I won't need any special tools but crank holder.
I need to replace valley pan gasket and radiator(preventive), so it will be 1
decent size job.
I'm wondering if there any tricks doing that job or everything straight
forward. Also, what else I need to replace while doing that? I have all new
intake gaskets and I will need to replace valve cover gaskets again, as it's
not good idea to reuse them..
THanks,
Ivan

Message-ID: <[EMAIL PROTECTED]>
Fundamental issue here, getting back to the original point, I think):
There was little engineering reason, other than sourcing expediency, to use
904nm lasers for this application, and I know of discussions in the
engineering community at least as far back as the '70s that indicate any
effective modulated distance-following anticollision or intelligent cruise
control should be made independent of police or other enforcement systems --
as true for microwave radar as it is for those using IR.
This is a 904nm issue, not a modulation issue. I can't see any particular
reason why fairly cheap filters, dyes, etc. applied to the external lens of
just about any LED taillight cannot adequately filter the effective range
that would otherwise eliminate detector 'falsing' -- which fairly promptly
makes my paranoia detection light off. I can just see the snickers at some
place like NHTSA as more and more "innocent" modulated-904-nm-laser
applications hit the road...
There are very, very good potential uses for modulation of some of the LEDs
in taillights for distributed vehicle control -- none of which, afaik, are
anywhere near standardization let alone production. This leaves you with
the 'modulation' provided by cheap multiplex drivers or PWM for power
conservation -- something that the supposedly intelligent circuitry Mike is
supposedly putting in his detectors OUGHT to be capable of recognizing.
Except that the next 'logical' step in police-laser implementation would be
to match this profile when generating the targeting pulses...
Additional paranoia: Expect to see a push to make equipment like Blinders
illegal, and put real teeth a la MADD into enforcement against users
thereof, based on just the sort of "safety" concerns regarding interference
with laser cruise control mentioned in a couple of those recent posts.
After all, it's even less of an intellectual 'stretch' than cracking down on
methamphetamine because ether is potentially dangerous to neighbors...
