Hey guys, saw this posted over on reef2reef and thought some people here may be interested as well. basically you use an old smart phone as the camera and your current smart phone as the viewer. Each phone gets a different app depending on the function it's serving.
I'll be trying this over the weekend with my old 4s and my 6. If anyone else tries it let us know!
