I mentioned a little while back that I planned some mods to the set of Wireless Flash Triggers I bought on Ebay (also known as Ghetto Wizards). Mostly, I’m done, with one more receiver yet to finish. I thought I’d share my results for anyone interested. Most of what I’ve done to my receivers is based on Jeremy Kuster’s work. My source for the internal antenna mod on the transmitter is this post by Strobe Monkey.
Regarding the receivers, Jeremy offset his battery holders more so than I did to allow for the addition of a sync cable port. I thought long and hard before finally doing what I did. I didn’t care for the unbalanced look of his layout. If I add the sync port mod down the road, there’s still some room on the other side from the batteries as well as going in from the bottom or the through the hole currently being used by the cold shoe mount (assuming you’re willing to give up that mounting option). I think the lanyards are a suitable solution so I’ll probably go through the mounting hole. In the meantime, I’ll probably get a couple of these from gadgetinfinity.com.
Another thing I didn’t like about Jerremy’s setup is that it eliminated the possibility of using the original battery. By putting the battery holder wires in where I did, and routing them correctly, the option still exists to use the original power source.
When it came time to attach the battery cases to the receivers, I originally just slathered on some quick epoxy. That lasted all of about two days. Once I figured out that method wouldn’t hold up I pulled out my Dremel and roughed up both mating surfaces before using some slow curing epoxy. I expect this will hold fine now.
The covers on the battery holders I picked up at Radio Shack required a screwdriver to open them and I didn’t like that, so I added the two-sided Velcro so I could nix the screws completely. There’s still a screw necessary to access the battery in the transmitter, but there’s not real option to avoid that one.



I originally planned to do the external mod like Jeremy, but the internal method seemed to be just as reasonable. I took a couple of tries with the wire length to get reliable triggering. I haven’t done any long distance testing, but a cursory test through three walls from the bathroom to the kitchen resulted in a 100% success rate over twenty attempts.
This has been a fun little project. I had no idea what I was doing for the most part, even down to this being my first time soldering electronics. Thanks to Jeremy and Strobe Monkey for being so generous with their experiences.
