Walmart.com is temporarily unavailable due to high traffic volume. We appreciate
your patience. Please check back shortly to see our great values.

Gawd, now I have to go to the store to pick one up :(

GAWD, These kids nowadays have it made!
Check out this kewl hotwheels radar gun on sale for $20.00 at Walmart.
I wonder if it's accurate though, I might just pick one up and
dissect it!!
Anyone already get one of these, is it accurate? TIA

And how high can it record speed? I'd like to try and nail a few
pimple-faced, pill-popping, high school dropouts who thinks 25MPH
speed limit means it's OK to rip down the road at 75. If it's
accurate enough, a video camera recording the speed and the offending
vehicle with its license place would stop them hopefully before they
get a new hood ornament in the form of a 3 year old child.

Hmmm... since it is the same as x-band, I wonder if I used those on
freeway, maybe I could scare a few lead foots who has radar detector?
Say I'm coasting down the expressway at posted speed limit when
someone zips past me as if the driver's pants were on fire. Pick up
the toy gun and zap the offending car. If the driver has radar
detector on, he'd panic and slow down a bit.

Very easy to build a gunn diode oscillator and scare the pants off
leadfoot at a 5+ mile range.

You need a gunn diode, 8 volt regulated supply, one small bypass cap
and copper end cap pipe fitting and piece of copper/ and some brass
screws to make a mount for the diode.

If you have an old radar detector with good gunn oscillator it can
also make a good X band source for triggering radar detectors - just
isolate the diode/horn sub assembly (you don't need the other parts
just the gunn diode, cavity, bypass cap and power supply). Tune the
cavity screws for maximum effect.

A video camera with on screen timer and known distance markers could
do the same thing - poor man's Vascar system . . .

Then you'd only have to fight the bureaucracy to make a citizens
arrest stick . . . or just convince the local TV station to take up
your cause - that would probably be a lot easier than dealing directly
with government.

I suspect its readout is scaled to Hotwheels scale, not
actual speed.

Nope, it does "real speed" the amazon review says;

Amazon.com Review
Ever wonder just how fast you get your favorite Hot Wheels car to go? Or how
speedy you are on your own bike? You don’t need to be pulled over by a cop to
find out. The Hot Wheels Radar Gun does the job for you, using all sorts of
state-of-the-art technology. Just set the scale to 1/64th or real speed, and MPH
or KPH, aim the gun at objects coming toward you or moving away, squeeze the
trigger, and check out the digital readout. Simple as that! Now you can set new
speed goals, and actually find out if you’ve attained them. The 1/64th scale
speed reflects the fact that Hot Wheels cars are 1/64th the size of a real car.
So if a Hot Wheels car goes 10 MPH, the calculation is 10 MPH X 64 = 640 MPH!
Now we begin to understand why those wheels are so hot! Requires four "AAA"
batteries (not included).--Emilie Coulter

On the box it claims it does actual speeds up to 100 MPH. It's a hot item on
EBAY, but you can get it cheaper at Walmart or Amazon, the sell it on ebay! ;)

Interesting. Someone must be out there flogging a set of components
for radar guns. I bought a Bushnell one for measuring baseball speed
for < $100 not too long ago. It seems to agree fairly well (within a
couple MPH) with the professional models.

Unit operates on 10.525 Ghz and has a range of 39 (Thirty Nine) Feet....

Now for the laugh of the day. I was in the local Office Depot and saw a
pair of GMRS/FRS Ht's on the shelf. The package claimed 14 (Fourteen)
Miles range on GMRS High Power....

That is correct! It uses a 10.525GHz DRO circuitry.
Someone took it apart and posted the photos on the web.

If you look at the web page where they tore it apart, you'll see it's little
more than a microwave transistor oscillator using a DRO, another transistor
for the mix, and a PIC microcontroller for all the "smarts." The PCB itself
is a pair of (planar) antennas for Tx and Rx.

Clever idea... I wouldn't be surprised if someone thought it up and realized
they'd make a lot more money selling the design (and consulting on it) to toy
copmanies than just publishing it in, e.g., QEX.
