Ya David is still selling them, same model as cheapdmx.com and Ray Wu's store - I have one sitting here in front of me. Nice small DMX module, usefull for what David sells, to be able to be put into whatever your making and just use RJ45 for signal/power injection.
I am going to have to order some of the 3 conductor wire for my northstar to use smartstrings in them to get signal/power from one tip to the other. Will be able to use just one smartstring controller for the entire 76 rectangle modules I am gonna use (if I remember my count correctly). It will fall just under the max # the controller can handle.
Got the star sitting here now, just waiting for the lights to show up. Gonna have to order another hub/16 controller pcbs from RJ here soon
Using the 1st 12 of them for a cosmic string Mega tree clone setup at 1/3 the cost of the LOR product.....
