   at the LUGradio show there was a guy 
with the TVbegone gizmo (turns any 
television off, that's all it does, but 
it does it perfectly, kind of a Unix 
philosophy for electronic gizmos. 
   he's got other stuff, though this is 
his big hit. 
   i plan to check him out. he's friendly 
and might be an interesting field trip 
for the two of you. 

cornfield electronics is on 1800 market 
street in SF.
