New Toys! – Radiopopper Customization

Guess what I got today...

...BOO YA!

That's right, I got my transmitter and 2 receivers from Radiopopper! These things are BADASS. If you've never heard of them before, do yourself a favor and visit I haven't had much of a chance to get some test shots using these newfangled contraptions. I did, however, want to share with you a little customization action I did to them.

Radiopopper recommends you use a piece of gaffer's tape to secure the fiber optic bead over the IR sensor of the slave unit. This is definitely the easiest and best way to mount it, but I hate waste and I don't even have any gaffer's tape, so here is my solution-you might like to try it, too.

First thing I did was cut a 2-inch long piece of the loop side of Velcro brand, uh, velcro. Then I cut a piece of craft foam sheet (get it at craft supply stores) 1 inch by 1 inch. I removed the adhesive backing from the velcro strip and folded 1/4" of each end onto itself so that adhesive met adhesive and I had a piece of loop Velcro that wrapped around on each side. This left a square 1"x1" on the adhesive side to fit the foam onto. I placed the foam onto this patch to create essentially a velcro band that was entirely loop on one side and the other side was a square inch of foam bordered by velcro on each side. I then put small strips of hook velcro on either side of the infrared sensor. So this makes it possible for me to velcro this band over the bead on top of the IR sensor for a secure connection.

I tried to describe this as best I could, but after reviewing what I wrote, I could see how I might appear to make about as much sense as a screen door on a battleship ("now make like a tree and get outta here"). A picture is worth a thousand words, so just check out the following shots and they should make more sense of it.

So that's my custom Radiopopper fiber optic bead infrared sensor attachment majigy. It works great and it's easily removable. Mine is for a Canon 430ex, but the principle applies to any flash. I highly recommend slim Velcro brand velcro. It's strong and incredibly thin. I found mine at Home Depot. Here's the velcro piece in live action.

These things are GREAT inventions. Thank you, Kevin King, for creating this magical contraption. I wuzn't smart enuff to think it up. I will definitely be posting a blog soon about the units themselves and how they work in a real, live photo shoot. So stay tuned.
