While I love the Nikon CLS system, I find that it can be problematic at times. The flashes aren't always able to "see" each other. I decided to go with radio triggers. I started with gadget infinity triggers; then I graduated to pocketwizards. However, when Radiopoppers announced their JrX line of triggers and receivers and the potential to adjust the level of flash output, I decided to give them a try. Unfortunately, the JrXs require the not yet released "RP Cube" to adjust the flash output. With how long it takes Radiopoppers to release their products, I chose not to hold by breath.
I decided to build my own RP Cube.
I ordered a couple of Nikon AS-900 cords from BH Photo. The cost around $10 each. I chose these cords because I have an SB-800, SB-600, and an older Vivitar flash that supports (maybe) Nikon TTL (an older version). As a result, I cut it, and used the hot shoe for the SB-600, and the female three prong side for the SB-800.
It is pretty cool to wirelessly control the power of my strobes. Another reason I went with the radiopoppers is that the ability to control my alienbees is built into the JrXs without modification. Here are some non-scientfic shots of me wirelessly adjusting the flash in my kitchen. Note that there are two flashes in the picture. However, the SB-800 is turned off and is not firing. These images include just the SB-600 firing from the DIY RPcube hot shoe.
