Thinking about setting up a "Grinch" talking face at the front of our property to greet and nag our visitors via a pir sensor connected to my LOR G3-MP3 Director Wanting "Grinch" to greet and then "Nag" people to remain on paths and not to swing on the strands of lights. Any advice on making "Grinch" Corro ? Wire frame? Aluminium ? Pro's and cons. I am thinking an Aluminium frame, but all I can find is 6.2 mm diameter and I would prefer 5mm as I want to use clips to hold my Leds in place.
