A sure sign that you found that "one-in-a-million" woman. Congratulations!

That, and "Sex is like a Chinese dinner for two. It ain't over until you both get your cookie."
It is a Doppler radar used to gather precise and continuous data on a bullet in flight so that exact exterior ballistic data (principally coefficient of drag) can be calculated. It would be used by precision shooters, cartridge developers, rifle developers, military snipers, etc. to enable extremely precise and repetitive targeting of their rounds. My radar will be quite small, about the size of a standard desktop computer and cost less than $4,000.
The most fun in this project is not the electronic hardware (although that is real pleasurable to work on). The real fun is in the math that calculates the velocity and then converts that into several coefficients of drag.
The Doppler effect (Christian Johann Doppler, 1803-1853, German physicist and mathematician) is an effect of physics whereby a transmitted frequency will be different than the received frequency when there is apparent motion between the transmitter and receiver. Exact velocity data can be extracted by comparing the transmitted frequency to the received frequency and measuring the difference.
A (very) big brother of my Doppler radar will be the one used in the upcoming war with Iraq. It is a system called J-STARS and is flown on an Air Force E8C (Boeing 707). The J-STARS stands off from the actual battle scene a safe distance and uses its Doppler radar to look at the battle ground and only process and display those return signals that are from moving targets, i.e., vehicles, tanks, etc. As long as you have adequate information as to who is friend and who is foe, it turns the shooting match into a turkey shoot. (As the Republic Guard found out on the "Road of Death" from Kuwait to Iraq in the last dust up over there.
Now aren't you sorry you asked!

Yes, and the trick is knowing that the surest route to the cookie of your dreams is to totally ignore your own cookie and focus solely on finding that cookie for her.

And if you're paying attention, she'll lead you right to it.

Did you ever hook up a propane bottle?
On a jet engine? No.
But then, the lefty loosie rule applies to standard nuts, bolts, B-Nuts and cannon plugs.
Isn't that what takenoprisoner does for recreation, too?
In my younger days I took an acetylene torch to my VW bug (as an act of vengeance) and by the time I got done I had a dune buggy, complete with roll bars, a flat bed over the rear, a lowered engine, etc. Got done about 6 in the morning, popped both boys in it (5 and 10 y.o.) for a "test drive" and headed out across the country. We drove from California to Florida, up to Illinois, across to Utah and then back home. Took us about 6 weeks.
The boys loved every second of that trip until I'd throw the map out and charge across the back country on one of my "short cuts". I got the reputation for being a deranged "Lewis and Clark". I found a new pass across the Wasatch range through mountain trails and forests that came down right smack dab in the middle of Park City Ski Resort, in the mountains East of Salt Lake. You can't believe the looks on the faces of the people on the lifts and walking the slopes when they saw our dune buggy pop out of the woods and down the slopes! The boys threatened to never get back in the car again unless I promised no more "short cuts".
Both of those boys grew up to become Marines, attend college, get married and make me a grand dad, but they still make me repeat the pledge before they get in a car when I'm driving.
Adventure...It'll kill you if you do it too much or too little.
