On this forum? I believe the biggest help would be someone experienced with power electronics giving advice for a good buck converter that takes 5V, 3A (such as from a GekkoScience USB hub) and spits out a nice clean 0.4V with dozens of amps available. But it may not even be required for now. I suspect the chips don't start hashing and pulling enormous amounts of power if you don't instruct them to.
No I don't think he is registered in this forum, at least not officially.
You can use search terms I gave you to find him on internet, github (@mfolejewski)and I think he is active on twitter (@Mirek34416541).
He is working on boards and other bitcoin related stuff.
