Quite so: a watchdog ensures that your system will recover from a problem - it does not fix the underlying problem!

... and during development, a watchdog may hide an existing problem from you so that you are not even aware that something needs to be fixed.. So it's best to activate the watchdog late in the game, just before you begin your final testing.

   What is exactly RLY fuction?            01/01/70 00:00      
      Effect of relay            01/01/70 00:00      
         Isn't it called EMI?            01/01/70 00:00      
            Sure - radiated and conducted            01/01/70 00:00      
               Ok, thought so :)            01/01/70 00:00      
                  Maybe it's a test?            01/01/70 00:00      
                     Not very kind to operator :)            01/01/70 00:00      
         A diode helps.            01/01/70 00:00      
            But immunity is best!            01/01/70 00:00

      I'll build in some random delay next time :-)            01/01/70 00:00      
   the solution will be here            01/01/70 00:00      
   I'm puzzled            01/01/70 00:00      
      It damps out the relay voltage spikes?            01/01/70 00:00      
         not much, if any - 33pF?            01/01/70 00:00      
            Should be a printing error.            01/01/70 00:00      
   let's focus            01/01/70 00:00      
      Of course it is possible.            01/01/70 00:00      
      why focus            01/01/70 00:00      
         because......            01/01/70 00:00      
            Part more susceptable to EMI?            01/01/70 00:00      
            'experiment' all you want            01/01/70 00:00      
            prevent problems            01/01/70 00:00      
      where did we not focus?            01/01/70 00:00
