I am very happy with the operation of my minimad and I have opted for the above other options to use it in a fixed installation in a museum, where stability is the most important in this case. I choose the Minimad mainly because its use is extremely simple, because it will allow to readjust warping if necessary. So I'm going to ask for 3 more minimad to try them out in sync. I have some questions:
1- According to the characteristics of the minimad, it is possible to synchronize several minimad connected by ethernet. But that question a silly question ... I take for granted that to connect more than 2, it has to be all connected to an ethernet hub. Is it so?
2- If I connect only two Minimad can they be connected directly to each other without hub?
3- Another problem that worries me is the stability in the on and off of the current. If there is a power failure, can there be any problem with the rapsberry pi? Since it has no power button, I imagine that when reconnecting reconnect everything again.
thanks in advance
