I test my CUBE and it works great. The white wire should be on the center connector.

Thanks for the input George! From what I’ve gathered from folks, the only Nikon TTL flash that won’t work with this setup is the SB900. It apparently uses a different method of firing than the trigger/quench method.

Just got done manufacturing several as per the great write up. They not only work perfectly with my SB-800, but with SB-26’s and SB-28’s as well. Woo-hoo!

A couple of items that others might find useful:
1) When wiring things up, the white wire goes to the center of the plug.

2) Out of the 12 Radio Shack plugs I bought, two were defective internally (as determined with a multimerer). Radio Shack carries more expensive plugs too; next time I’ll pay a couple of dollars more.

3) You can “daisy chain” cubes with the cables or with unadulterated AS-E900’s to use one popper to control several flashes. Having two mounted together to double the light will be useful.

Thanks for the detailed instructions.

Maybe time to contact Mr King over @ RadioPoppers and ask for a job. Mr. Hobby mentioned RP may be looking to hire the Basic-to-Studio Hackers:

One would hope they’d also be willing to hire someone to finally make a us a d#*! cube already, although Mr. Faulkner is prolly correct that those of us soldering-inclined will probably just make our own for the ~$15.

Thanks for the great DIY!

Congratulations, Mick! I am a Nikon and I use a D300. I think that you’re right about the short pins. Call the guys a RadioPopper. They have been very helpful when I called and offered advice and were willing to trade out a receiver if it had a problem – it didn’t (it was me) but would have traded it if it had.

Enjoy your cubes and be sure to share your pics made with the DIY Cubes!

Thanks Tom. Got two done today finally. One question though – don’t know if you still use Nikon, but I notice that the pin at the bottom of my JrX transmitter is tad bit short. So when I put it on, I have to press it down a bit to ensure good contact with the shoe. If I don’t do that, my flash misfires a lot. I have a D300. Not sure if my unit is slightly defective or it is just the way it is. Thanks again for a great tutorial.

Hi Mick

That plug won’t work with your JrX studios as the DIY mod plug. You will need a stereo plug to support the three signals: ground, trigger, and quench.

Don’t throw away that mono plug though. It is used with Alien Bees to turn off the optical trigger when you connect the studios wit a phone cable.

Cheers,

Tom

I just noticed that my JrX studio receiver came with a 35mm slave plug (http://i.imgur.com/3iRS0.jpg). I think it’s mono instead of stereo like the one from the Shack. Will it work or do I need a stereo plug. Thanks!
