I will be installing about 10 television screens with RPI's attached. during a small festival. The screens will show a basic slideshow with the sponsors, timetable and such things, nothing fancy.
I've done this before, with the RPI's in a default black plastic case, which is sturdy enough for the use. The only problem I have is with the cables: they are far too easy too unplug. Even accidentally if somebody is messing with the cables of the taps or something like that.
So I'm looking for a case which you have to open to unplug a cable (with some kind of cable guard...?) and with some built-in strain release, so if a cable gets pulled the connector on the RPI doesn't break off. I also hate the SD-card sticking out. (I know you can buy these special smaller adapters, but I would just like a bigger case.
I know you can buy these short cable extenders to use as port savers, but I don't really like this, as this is another point where the connection can get broken.
Does anybody know if something like this exists? Commercially?
Proto Armour seems the best I've found, but they don't have some kind of strain release.
Something like 'the spin' (http://www.buildingthespin.com/). But this isn't commercially available yet. And It doesn't have to be round, or good looking at all.
So, any ideas?
