I have a very old light sensor I got from maybe the SF 
Lighthouse.  It's a small molded plastic thing into which you 
plug a nine volt battery which becomes the handle.  The unit has 
a knob and can be used either as a passive light probe or can get 
feedback from a small light that radiates from the same lense 
that receives light.  I never figured out the uses for that but 
maybe it was a primative way to figure out colors.  Jim WA6EKS

Lou:

What kind is the one you found?
Can it distinguish between close lights?

Ed and list,

Yes, I think I would've tried that but, fortunately, I found the 
old one a
few minutes ago so all is well.  Man, I'm surprised at how hard 
it is to find
these things online nowadays.  I realize there's an iPhone app 
for it but not
all blind people have iPhones so you'd think there'd still be a 
need for
them.

 Lou, could you partly cover the hole to desensitize the one 
unit? might be
 worth a try..  G L

 Hi all,
 i picked up some part-time hours at a local radio station and I 
need a
 light
 sensor to tell me the status of various things on the audio 
board.
 Somewhere, I have 1 or 2 of the triangular-shaped ones with the 
slide
 switch
 and the built-in permanent shade around the sensor.  That's what 
I used
 when
 I was working before and it worked just great for that purpose.  
However, I
 can't find it and I need to replace it sooner rather than later.  
I also
 have
 a sensor from the NFB which is essentially a frame with 2 
tripple-a
 batteries and it works well but is far too sensitive for this 
job.  It has
 a
 removable shade but I cant get it to stay on.  Any 
reccomendations? Thanks
 and 73.  Lou WA3MIX
