Follow the picture as you can. The post are made of black cocktail straws. The diagonal cross supports are made with with square wooden toothpicks. I made two antennas, one with a large unbent paper clip, and the other with a cocktail straw.  I used a vice to unkink the paper clip.  You can add a red flasher led at the top of the coctail straw.  I am also going to add a small white 1.8 mm led flasher below the hut.  The two little electronic paks can be hidden in the hut.
