TriggerHappy adapter hooks your Android or iOS device to DSLR cameras for total remote control
Using your smartphone's audio jack, the TriggerHappy adapter goes into a DSLR's input port, and allows you to control the camera from afar with the dedicated Android and iOS apps.
The project has already gotten a Kickstarter fundraising intiative, aiming to collect $25, 000 towards its development, and the pledges have more than doubled that already. A $50 donation will reserve you a place in the first line of TriggerHappy owners, and the countdown to project completion has 44 days left as of now.
It's a pretty neat idea for the numerous shutterbugs out there, since the aptly-named TriggerHappy allows for "single-shot triggering to time lapse modes where the shutter length, interval, duration and number of shots per interval can all be individually adjusted".
The remote control even has an HDR mode, and can trigger a shot using the phone's accelerometer, as well as the ambient light sensor, or even get activated by noise, using the phone's microphone.
