For those interested in making this themselves.
Google
picoip and check youtube as well. Will cost you around 30-40 bucks for the parts

And if you need the batch files (windows) to setup/reset rigs, pm me, i can hook you up

With rig separation on optical transistors ?
For 8 for 30$ or 32 rigs for 60$ ? right

I dont think so

I advice not to connect each rig because if one rig will have power problem then it could burn out the rest.
Separation is really important !
