Hey K-Mart is going broke (about time!)

I bought 2 automotive Backup alarms for $8 each.  There are lots of them still
in stock at the Colleyville K-Mart.

It has a focused 40kHz transducer, measures from 15" to 5 feet and runs off
12v at 30mA.

It has LEDs and beeps for the distance increments of 15", 2', 3.5' and 5'.  

This could be useful and possibly hackable.

Get them soon if you want them!
