Face and Body Scanning / Re: software/hardware/remote control for multi camera?

Hi,
It is a good idea to share configurations, as it seems that everybody it developping its own control system.
I have now a rig with 15 canon 600D that works quite fine and I hope will grow with time.
I use smartshooter for camera settings and automatic download of images to the computer.
It works very well but the hard part is to get all cams with stable usb connection to the computer.
As already said in the forum, good cables are required. usb 3 cables have a better screen and allow more length than usb 2 cables.
for the cam triggering I don't use smartshooter because of the delay between cams which increase with each additional cam. it works if you are in an almost black room with the shutter open a very long time (2-5s for 10cams) and trigger manually the flash when you have eard that all mirrors ar up.
possible but not very convenient and very un-confortable for the model that go from full black to big flash lights
instead I have developped a small electronic board piloted by an arduino that drive relays. contacts of relays are wired to the remote control of each camera.
one additional relay is driving the flash remote control. that way it is easy to automatically fire the cam and the flash after a predefined timer (120ms in my case).
connected to the arduino, a wireless remote control from adafruit allow firing from where you want.
with this config I manage to get sync at 1/5s without any black images
the bottleneck is the download of pictures to the computer that takes between 20s and 30s (for 15 pics) even with a SSD. it is a very long time when searching for a nice pose
