Doug,

There is an absolutely great article in Nuts and Volts Mag. this month on
just this type of thing. If you don't have access to it, I can make a
photocopy and mail it to you.

Regards,

I have a need to measure speed. I thought about using the polaroid
sonar mudule (I have several of these that work) from the sonar
cameras as a 'radar". Have it measure the pulses and do some
math on the ping results. Any one else ever do this?
Main thing I need is some distance/time math to do on the stamp.

I could use some help on the circuitry, too, but I have the sonars
working to measure distance to the inch but need to know how to
use the differences to measure speed.

Thanks

Doug

I don't get Nuts & Volts, so if you could, could you send me a copy
of that article?
If you have a scanner, scan it to a JPG and attach it.

Thanks

Doug
