Is this a DIY, personal module or something that will be available?


Yes, it is DIY. I build it inspired by the DIY passive OR combiner by stk (http://www.modulargrid.net/e/other-unknown-diy-passive-or-combiner) but took 6 inputs and not as discribed there I took 4.7k resistors.


Thanks for that,  a 2hp one would really be perfect...


That's for sure. A 2hp one is possible. And I think, 5 Ins and 2 Outs are more convenient and next time I choose for better sockets.
