    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

    your patience. Please check back shortly to see our great values.

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

    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.

    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.

    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

    The link worked using Netscape 7.1 and IE 7.1
     
  10. I suspect its readout is scaled to Hotwheels scale, not
    actual speed.

    I stand corrected. Thank you.

    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! ;)

  14. 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.

  15. 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....

    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.

    They want to grow up to shoot bullets at live people.

    At least 50 at a time.

    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.
