I took apart a broken calculator. It had a circuit printed on paper that the buttons pressed on that went to I guess a LCD controller that went to the LCD screen.
Is there any way to control the screen myself? Either by the cable that went from the controller or the places where the paper circuit attached to the controller?
Like by touching it with a wire connected to a battery or something.
