[sdiy] OT: Help with polygon scanner from copier

[harrybissell at wowway.com]

Echo... not likely to be useful at the speed of light. It would be a really
short delay unless you bounce it off the moon...

Scanning audio to different channels... quite possible but not real practical
unless you needed to have (let's say) really awesome high voltage isolation.

The output of this is a point source being swept really fast... so the
audio receiver would have to be quite long to get more than some instantenous
voltage.

It might be useful for a supermarket barcode reader...   <bfg>
