Simple Samsung NX Remote Shutter Release From USB Cable

Samsung makes some nice cameras, but they have fallen into the trap of building proprietary controllers. Their NX models, for instance, have a micro USB port rather than the more usual 2.5mm socket for triggering the camera remotely. What’s a hacker to do?

[Niels] did some poking around, and found that it is pretty easy to trigger these cameras remotely, because Samsung simply moved the standard connections for half-press and full press of the shutter onto the USB socket: ground D+ (pin 3) and the camera focuses, then ground D- (pin 2) and the shutter is triggered. In his Instructable, he covers how to build a simple remote from a micro USB cable and a couple of switches.

Don’t feel left out if you have another type of digital camera: there are plenty of ways to build a simple shutter release switch with a few simple parts, or ways to put a microcontroller in control for more sophisticated shoots.

    1. Yes and? Many buttons are like that, although often it’s hidden in a small plastic housing.
      The quality depends on the material used. And how well the case is closed from any ingress of moisture and such.

    1. Hallo Antibore : nice to read some else also on same interest. If you still have any of these units, Would you be willing to ship to Johannesburg, South Africa ?

      Kind regards, Gidi Williams

    1. Looks like it’s, getting a signal from the flash connector to indicate when a picture was made.
      Or does the flash connector allow you to trigger the shutter? I’m a bit confused by that photo.

  1. I’d lie to thank you for the efforts you have put in writing
