#353795 Wiring an underwater camera to external power?

Posted by SteveB on 27 October 2014 - 05:19 PM

That's an impressive little beast, especially at that price.

I had a quick Google and you just need to pulse the focus pin to GND (I'd expect 100ms would be a good). I'd suggest using a digital in, transistor out optocoupler between the microcontroller and the camera. That would be the minimum number of components to wire up while being pretty much bullet-proof in terms of camera safety. 

It looks like Nikon use a variety of proprietary connectors so I'd buy a cheap shutter cable release to match the camera and then cut the cable off to get the connector and cable.



#339434 Dive Destination while recuperating from shoulder surgery

Sorry to be the bearer of bad news, but a shoulder takes a long time to recover. I've had all of mine done and they were each 6-8 months before I was diving again.

It's not the heavy work (tanks, ladders, cameras, etc) that gets you, it's trying to push your arm into a wetsuit, putting a mask over your head or shooing away a fly. It's very frustrating. Sorry.
