    Hi everybody,

    I found in a very known magazne a remote-controlled digital dimmer that I have planned to make. Although you can get similar dimmers in shops, this one seems exceptionally great. My question is: this dimmer was created to operate under 230VAC, with the possibilte to change the circuit for a 12VAC lamp. To construct it, should I make some changes to the original circuit, considering that mains where I live ar 110/120VAC? Will it work with no changes? Does this affect the zero-crossing calculation? I haven't worked with mains directly, so I don't know much about that. If someone can help me, I can post concrete info about the project. by now, i'm posting a circuit pic. It explains the that the green values are for testing with a 12VAC lamp before the final mounting. Thanks

    Sorry, but that notice about how "contact can be fatal" puts it outside our guidelines.
