I'd like to capture some scratch audio tracks during some upcoming filming, and I've thought that a logical, inexpensive solution is just to use my old iPhone along with an external mic that attaches directly to the dock connector of an iOS device. I'd like to somehow mount the iPhone on my SR3's carrying handle which has two 3/8" screw threads.
I'm guessing that there must be some sort of rigging attachment or clip available that would be good for mounting something like an iPhone to a 3/8" thread mount. B&H has quite the extensive selection of support and rigging accessories, and I'm looking through the listings now to find some options, but I thought I'd ask and see if anyone might have any specific suggestions. To minimize my rig's vertical footprint, I'd ideally like to mount the iPhone flat on the camera (so that the touchscreen is oriented toward the sky).
