If you are adept with electronics, build yourself this sound-triggered remote control for high speed photography. When you pop a balloon or smash a glass with a hammer (as you’ll watch in the video), the sound that is triggered travels back to the sensor and fires the flash which will record the action onto your camera which [important] has the shutter already opened [therefore you need to be in a very dark room].
Got that? It’s not really a camera remote trigger so much as a flash triggered by sound. “Sounds” like a complicated way to do things. As the video shows, sound travels too slow to enable catching the action at its peak moment.
It’s a great little DIY electronics project, but if you’re really into high speed photography, we recommend that you get yourself one of those cheap 1000fps high speed digital camera instead.
