Here is something that may be of use to the person who is looking
for a directional device to help a blind individual find "home".
Pan-Com International (a division of Panaxis Productions, PO
Box 130, Paradise, Ca  95967-0130 916/534-0417) sells plans
for a "tailing transmitter" sytem that is intended to be attached
to a vehicle, and can be followed with a direction finding loop
antenna.  Cost is less than $15.  See p.7 of their catalog.
It might work here, although the person trying to find home
would have to be the one carrying the direction finding loop
antenna -- that could be cumbersome (an umbrella wired with a
loop?? @:^) ).  Just a thought!
