Clapping

Thank to Jai for letting me use his Amazon Prime account, I got my TriggerTrap within 24 hours. I am very pleased with it. This is really a clever little gadget for photography, which uses all the resources of you smart phone and transfer it into a cable release, timer, sound trigger, motion trigger, even a face detecting trigger. 

I did a bit experiment of the sound trigger this evening, had trouble with the sensitivity adjustment of the app but finally got the result. Well, I also used quite a lot flour and made a mess on the carpet.....  It is all clean now, my wife doesn't need to know about that ^_^
