Sony QX10 mod for remote wire shutter trigger

The Sony QX10 is a nice lightweight 18 MegaPix camera for very little money (mine cost less than 100$ online, shipping included). It looks like a good one for aerial mapping missions. Unfortunately, it does not support USB cable remote triggering (unlike the much more expensive models in the QX family). Also, a smartphone app allows to trigger the camera via Wifi but that does not allow a direct shutter trigger control via Pixhawk, which was the purpose for getting this camera. Therefore I decided to modify my QX10 to see how trigger wires could be directly hacked on it...

Hugues, you really made my day with this mod. Thanks a lot for sharing

One question: how do you avoid shutdown because there is no wifi connection? Or if you focus regularly the camera does not shutdown?

Thx Paul,

This camera, as far as I know, does not shutdown because there would be no WiFi. The Wifi app is just optional; It is standalone and has all of the buttons on it to control it.

Awesome! That model has got to be the best for aerial mapping when looking at price, resolution, and weight.

So basically short focus wire to ground wire to focus, and shutter wire to ground wire to trigger? (Not completely sure from the video ...)

Does it focus and trigger if you connect all three or is a delay needed (could be done with a capacitor?) to first focus and then trigger?

Thx John,

It is much simpler than that : to focus , short focus wire to Gnd.

To trigger, short trigger wire to gnd. And it triggers with instant focus. (you do not need to focus before triggering).

Hugues, huge thank again, I really like this camera, there are some apps running python to trigger the camera, but it needs 2.4 Gh wifi that does interfere with RC. Any ways to stop or cut the wifi from the camera?

Great, thanks Hugues.
Just wondering is there any way to control the zoom function with rc signal?
And what about fpv, what port can we use (usb/multiport or hdmi)?

Nice Hugues; It's possible to use this technique with other cameras? I have a Panasonic Ts4 and shutter with a horrible servo.

Comment by Martin on February 20, 2016 at 11:50pm

@Cala, of course it's possible. Just open up the camera and solder wires to the trigger switch.

How quickly will this camera shoot subsequent frames?
