    Hi All,

    I am trying to create a digital clock like the one in the attached link. There are quite a few DIY kits available in ebay (India). I liked the one in the below link. However it looks like it do not have a battery backup to keep memory of the time when the power is off. Is there any way to include a power backup facility in this circuit ?

    Thanks in advance.
    Regards,

    I will not click on a pop-up to get the information required. Post your schematic here or expect an up-hill battle to receive useful answers.
