   Have you accounted for Vce(sat) ?            01/01/70 00:00      
   resistors are not a good solution            01/01/70 00:00      
      Have you considered a current mirror?            01/01/70 00:00      
         mirror, mirror on the wall            01/01/70 00:00      
            No question about it ...            01/01/70 00:00      
               But was that the question?            01/01/70 00:00      
                  I focused on the brightness match ...            01/01/70 00:00      
                     Doesn't it show that he's missed an important point?            01/01/70 00:00      
                        He doesn't really have to consider voltage            01/01/70 00:00      
                           for a (short) while            01/01/70 00:00      
   Sorry for the delay            01/01/70 00:00      
      The ULN works perfectly well - as far as it goes.            01/01/70 00:00      
      MOSFET Technical Info            01/01/70 00:00      
      Key term is 'logic level'            01/01/70 00:00      
         commom part            01/01/70 00:00      
            Catalogue?            01/01/70 00:00      
   Mosfet            01/01/70 00:00      
      I believe you'll have a problem ...            01/01/70 00:00      
         IRF530            01/01/70 00:00      
            Dig a little deeper, Chico ...            01/01/70 00:00      
               circuit... will work if I do this way?            01/01/70 00:00      
                  No!            01/01/70 00:00      
                  Look at the specification for IRLD120            01/01/70 00:00      
                     now i get confoosed            01/01/70 00:00      
                        High power            01/01/70 00:00      
                        He has digressed            01/01/70 00:00      
                           I suspect it's because he needs a constant current switch            01/01/70 00:00      
                              And I suspect that we are wildly guessing...            01/01/70 00:00      
                                 a little more specificity, please, Chico            01/01/70 00:00
