• 6" of bell wire (~18 gauge) soldered onto antenna hole.
  • 8/32" hole drilled for slightly-trimmed pen lid.
  • You should cut the trace here according to a lot of people - GraeArea
  • I had heard about that. This strip here is actually part of the antenna. I'm just hesitant to start cutting. ;)

Gadget Infinity Mod

Newer Older

With 6" of bell wire (~18 gauge) and the lid to a ball point pen, I improved the range of my Gadget Infinity wireless trigger from less than 20 feet to more than 200. (Final result here)

I just soldered the coiled wire onto the antenna terminal, and trimmed a pen lid with a Dremmel tool to fit in a 8/32" hole I drilled in the top of the transmitter cover. I couldn't believe it worked. My out-of-pocket cost? $0.

Caution: You can ruin your transmitter doing this. Consider yourself warned.

Lest I leave everyone with the impression that this made performance perfect, it does seem to cause more undesired flash pops. I don't know if that's strictly a result of this mod making phantom signals go farther, or the channel I'm using. I'll have to try different channels and see if I get fewer unwanted pops. That being said, the number of misfires was really low. I probably got 95% hits on the first attempt at a shoot.

Update: It's very channel sensitive. One channel pops randomly like a dance party. Another channel is perfectly well-behaved.

    where can a scrap piece of 18 gauge wire be found, or how can you tell if it's 18 gauge wire?

    slyder - Bell wire is solid copper (as opposed to stranded copper) and is what is used to wire up doorbells. It's relatively cheap, and you only need 6 inches.

    As for the gauge, there's nothing magic about 18. It could be 16 or 20 o 22 gauge - it just has to be stiff enough to hold its coiled shape. For reference, though, a small paperclip is made of wire that is approximately 18 gauge. (Come to think of it, you technically could use a small paperclip, but the metal is too hard to be coiled easily)

    thanks for the info i just recently came across this mod and i thought it needed to be more specific but seems you can rig just about anything up heh

    Seen in my recent comments. (?)

    Just stumbled across this mod.....it worked out great, and the price was right. Brilliant idea using a pen cap. Thanks for sharing!

    I am waiting on all the parts, ty ty for giving me a alternative to spending 650 bucks on pw -

    Now if someone would pls make a strobist version of the 17-55mm 2.8/f Nikon lens I would appreciate it - figure it should be doable for 100 bucks vs 1100 :D

    Tylenol7 - I don't know what you mean. A Strobist version of a lens? Strobist describes off-camera lighting techniques. It is not a euphemism for "cheap."

    can anything be done to the receiver to boost range ?

  11. makelessnoise 85 months ago | reply

    Well - with the receiver you're talking sensitivity, not range, per-se. It just listens for the transmitter. So long as the transmitter is 'loud' enough, the receiver will 'hear' it. The danger with messing with the sensitivity is that the receiver will start hearing battery noise or garage door openers and mistake it for the transmitter. These things are flaky enough as is, given all the undesired flash pops I get. I recommend only trying to boost the transmitter.
