Behold the monstrosity that is my USB camera remote:

It does look like a detonator but I’m hoping when plugged into two cameras it will look less suspicious. At least it doesn’t have a big red button on it!

I’ve done a little bit of handywork around one of the usb plugs so I can bend it earlier to get the cameras closer together. I can get the lenses about 100mm apart which should be OK.

I hope to get the software setup on the cameras then I’ll be able to take my first dual camera 3D Stereo Photograph.
