 		 #119724 - The facts about costs of Debouner chips
Responding to: ???'s previous message
I think some people might not know the exact situation here in India.

Here a MAX6818 is locally NOT AVAILABLE. Neither are its counterparts from other companies (like EDE2008). If you want it, you'll have to import it. The last time I checked out Maxim's website the cost was around $ 3.31 a piece
[https://shop.maxi...ilable.do]
That is if I buy 100 of them. And it costs me at least 10 dollars to import them. And the AT89C51 costs $0.80. So Maxim is simply too expensive for me.

            here is the schematic            01/01/70 00:00      
               I would try shift registers            01/01/70 00:00      
               just a note            01/01/70 00:00      
                  The joke is:            01/01/70 00:00

                     Re: The joke is            01/01/70 00:00      
      correct, but            01/01/70 00:00      
         I was assuming...            01/01/70 00:00      
   Bounce time of your relays?            01/01/70 00:00      
      Not very clearly            01/01/70 00:00      
         Bravo!            01/01/70 00:00

            Design is a state function            01/01/70 00:00      
               All the more using shift registers!            01/01/70 00:00      
                  I think your solution is better            01/01/70 00:00      
                     I guessed so...            01/01/70 00:00      
                  hidden part            01/01/70 00:00
