staircase handrail lighting
hi. not sure this is the right category but here goes.
i want to build a staircase handrail (interior) that has LEDs underneath it, pointing towards the stairs, and i want them to light up automatically when someone touches the handrail. a nice variant would be that individual lights light up following my hand position on the rail (following you up or down the stairs) and an even nicer variant to that would be to have the other lights fade as you move.
is this possible? and is it possible WITHOUT mild user electrocution? :D
i have no trouble building it, just not sure about the electrical part...
please share thoughts or ideas on how to make this!
