[sdiy] super-nice LED interface ..

[Jay Vaughan]

.. well, i had this very same idea a few years ago but have always 
had a hard time getting hardware guys interested in it, or at least 
the ones i know.  glad to see someone else got around to doing it:

.. thinking i should quit working on software, go back to school, get 
an EE [hardware] degree, and give it all another go once i can build 
my own damn machines ..

any of you hardware guru's got idea's for how this could be done in a 
nice affordable way?  are the LED's themselves being used for 
feedback, or is it an LED/LDR combo .. i can't quite tell, but i sure 
wish i knew, i sure wish ..
