TriggerTrap cable - how's it work?

Considering buying TriggerTrap kit, but I was wondering - is there anything to the cable? Or is it just a cable with some modular ends? Would the app work with a standard audio cable connected to my iPhone's headphone jack? Or is there some proprietary electronics in that "dongle" ?

I suspect there is some magic in the dongle. I've got one but don't use it, just lazy more than anything. They use audio signals that then a translated to the required electrical signals to trigger the camera. It works very well if you have a use for it. Might be problem if Apple do away with the headphone jack though.

TriggerTrap is a wired remote that uses a smart phone as the switching/timing device and is basically equivalent to any number of available combination remote/intervalometer. If you already have the smartphone the cabling for Pentax will cost about $37 USD. A wired remote with intervalometer features is about $20 - $25 USD.

That being said, the "magic" missing with a cheap wired remote is that you can configure a number of trigger options that leverage the microphone, camera, and motion sensor on the phone. Whether any of those meet one's use case is the important consideration. Face recognition might be sort of fun. If a face walks past the phone camera, the trap is sprung and your camera takes a photo.

Again, despite appearance, this is a wired, not a wireless solution. Dongle plugs into phone...cable plugs into dongle...other end of cable plugs into camera. A detail view of the dongle:



The dongle is essentially a demodulator that drives a three state switch.
