One of the features I found by accident when testing various Nikon cameras is that the Clap Snap can trigger any Nikon camera that is within range of the infrared output. This means that multiple camera angles can be used to acquire the same image, although I am not sure if one flash is good enough for more than one camera yet. I had my D90 and D60 firing after three claps, which was something that I will probably find useful when wanting more than one angle of the subject to be photographed.



It was also found that besides claps, snaps, or sharp bangs, spoken words could trigger the system, making it seem like it was actually voice controlled! I would yell "One, two, three" or even "Take my photo", and the system would recognize the burst of sound as three distinct voltage spikes into the analog to digital converter. It was fun to demonstrate the unit and tell people that it was full voice activated! Of course, that just gave me new ideas for later, more advanced versions of this project.

One thing that was missing was the ability to easily affix the Clap Snap in an appropriate position while using the camera on a tripod. Since the Clap Snap has limited infrared range, it really needs to have a line of sight between the infrared LED and the Nikon photo sensor which is located on the front of the camera body. To solve this problem, I added a small metal band that would just clip onto the strap clip, which was perfect since I never us a camera strap. I also thought about an adapter that would connect to the tripod, but the ability to hook it directly to the camera meant that I would never be messing around when it came time to use the Clap Snap. The metal band is just a 1/16 inch thick strip of sheet metal cut and filed out to sit in the camera strap connector. There are many other ways that a mounting device could be made, including Velcro or some kind of wire body.
