Help: I would like to build a switch activated by light from a star.
My good friends are getting married. they met 16 years ago. i would like to build a trigger that is activated by the light of a star 16 light years away. the trigger would turn on the lights set up for the party.
I have a telescope and have found a good candidate star.
what do i need to build it? is there a light sensor i can hook up to the telescope? how do i hook that up to a switch?
Please any help would be greatly appreciated.
