I was stunned to see this at Wal-Mart. Yep, "Hot Wheels" brand is selling an honest-to-god, 10.525GHz radar gun! Like $30.
It reminds me of Back To The Future II where that amazing, uber-cool hoverboard came in a crappy "Mattel" toy brand, and in pink no less.
Wow. The possibilities... ok I'm not sure what they are, but they've got to be plenty in there somewhere!
This guy's hacked it trying to measure an absolute distance as a rangefinder- difficult though. The transit time is quite low. Also I have to note that the ground and other reflectors are going to provide significant return as well, clouding the signal.

The interface is fairly simple, just a low freq difference signal (I calc like 1100Hz for 100 feet per sec).
