I'm interested if I can trigger my Panasonic camera with audio signal from my cellphone.
If I connect my Panasonic camera to some audio source by wire, would it be possible to trigger my camera by playing audio signal?
The cable is in two part...the one that goes to the phone and another one goes to the camera...the one that go to the phone has some electronics on the other end that receive the cable from the camera...so I don't think you can use a regular audio cable.
Using a tape recorder from the 80s with voice activation connected to a flash trigger with a second flash trigger connected to the camera via the usb port(standard trigger cable).
Plug a mic into the the voice recorder so you can put it closer or further to what you want, adjust the gain til the sensitivity is what you desire and go for gold.
The same basic setup can be used to trigger flashes for high speed work (open shutter, flash trigger actually on flash, sound of something hitting water or balloon popping... whatever... will trigger it).
.... here's the link, this circuit is activated by sound (mic) ...... instead triggering a flash, have it release the camera shutter. You can buy a cheap remote cable release and splice a stereo jack inline so as not to eliminate the function of the manual release ......
