   has a circuit almost the same as the original giving near top BUT he uses only   
   3 diodes and 10r. I tried this and no luck. I wondering if it me or not. I   
   know that David Like    
   many of you are very knowlegabe. I can post David circuit if you like. But I'm   
   not home right now.   
      
   Add more diodes in series.  The diode voltage drop (sum of all diodes)    
   has to be bigger than the LED plus resistor.     
   And and use a red led.  (less forward voltage drop than say    
   green or blue)
