Yes, I am using it. It is really, really basic (when I saw it, I struck
my forehead and said "Doh! Why didn't I think of that!").
It is no. 16 insulated stranded wire, spaced 4-1/2" (I think this is
about 600 ohms) held apart by spacers made from black polyethylene pipe.
I think that he simply made a jig with a hot wire to cut slots in the
ends of the pipe, and the wire is a press-fit. It is not beautiful, but
the wire and pipe should be OK in the sun, it's easy to slide the wires
around if you want to move a spreader (but they seem to be solidly
gripped). I don't know how it will do in the long run, but it seems
adequate.
