4 Iridium ingots, 4 Advanced alloy and 1 diamond dust in the middle
The recipe requires 8 iridium ingots in total. You need 1 iridium plate (4 ingots) for the all 4 energy flow circuits and another 1 iridium plate (another 4 ingots) for the lapotronic energyorb.
I'm assuming we're talking about Unhinged, so Energy Flow Circuits does not require Iridium.
You can make them from 1 Platinum Plate, an Advanced Circuit and a Lapotron Crystal in the Assembling Machine.
Damn, I should learn mystcraft...
