Hurry, Hurry, Hurry while they are still available! I picked these up at Radio Shack and they are mini phone splitters. As we show in the photo three of them can connect up so that you can run four strobes from one Pocket Wizard or Radio Popper. A vey simple solution that costs just a few dollars.
Since I started teaching, finding a simple solution for students to fire multiple strobes attached to a FourSquare block has been a challenge. This seems to be as cheap as I could find. You can check out one of my other posts on the “Belkin Rock Star” hub. Does exactly the same thing but differently.
