Just now p/u'd the LEDs from RadShk, needed a watch battery anyway, (not that I needed an excuse, as this looks kinda fun). If it rains tonite, I'll put this together and let you know how it works out. No rain, it's a bicycle ride and results will need wait til tomorrow.
The mode dial - top left from rear of camera - has a sliding dial at its base. There is a symbol that looks like the ML-L3 remote. That setting should do it. The one after it is 'mirror-up' which raises the mirror on first activation then opens shutter on the second.
Just got back from ride and getting ready to download the ap. Got the LEDs soldering down before. Let you know how it goes on my end in a bit.
Found the dslr.bot 'support' page. While I had set my volume to max in 'settings', I'd not maxed it out w/ the phone's volume buttons, and that did the trick.
This'll be fun to play with. Been trying to figure out how I was going to remote activate my camera from a distance as it sat on a tripod next to the bird/hummingbird feeders w/o spending an arm & leg. For exactly $25 and 45 mins labor I have the app, the IR transmitter and a 50'extension cord (already had the iphone). Should do the trick.
Haven't really concerned myself w/ HDR yet, but will play w/ the bracketing feature a bit to see what it can do in case my interests do some day lean that direction.
That's a good idea to use the dslr bot ! Haven't thought of it this way. Without an extension I've been able to go as far as 4 meters with 840nm LEDs... does the 940 goes further ? Is that what the number mean ?
The only bug I had with it so far is that when I plug the jack in my Iphone... it doesn't always connect properly and I've read it's a common problem with Iphone4 (Canada maybe ?)... have to play with it a couple times and then the contact works.
I used the 940's, but honestly don't know what the difference would be relative to the numbering. From inside my house I can activate routinely from 30' (10m). At 40' (raining outside and that's as far as I can go inside) its hit-and-miss, firing maybe 50% of the time.
Taken the IR transmitter on and off the phone maybe a dozen times, but no problems w/ contacts. I'm still on a 3gs.
I just assembled my own IR emitter for this and connected the emitters directly to a 1/8" plug (basically like the one they sell) so I have the flexibility of plugging it directly into my iPad or into an extension cable. The assembly was pretty easy - all that's left is to cover the exposed contacts with some electrical tape and/or shrink wrap. Getting it to work was also pretty simple and it appears to work quite well. So far, I've tested it from about 20 feet away without any issues. This may be the best app I've found for my iPad so far.
Highly recommended and thanks to the original poster for pointing this out to all of us.
And I just re-read my first post. This is compatible with most DSLR cameras that has an IR sensor. Not just the D7000. The good thing about the D7000 is that it has a IR sensor on the back so you don't have to be in front of the camera to make it work.
I didn't find the right "general" section to put this in but i'm sure a lot more users could benefit from it if placed in the right section... feel free to move the post.
It does not appear to be able to trigger the ML-3 receiver which is used with the D100/200/300/1/2/3 series of dSLRs. It also appears that one would need to code the timing of the IR flashes for other brands of digital cameras.
The "On/Off" code for Memorex TVs also triggers Nikon dSLRs that use the ML-L3 remote.
