Supply voltage for Volumite & AC1

Russ or Brian,
What voltage and amperage will we be needing for these controllers. (I will start off with Volumite and migrate to AC1 when available). I will be needing Balanced setup with 2 I2C boards for Joshua and Darwin. I am using AMD's ε24 power controller that uses a Bulgin push button to turn on and off will the AC1 provide ability to send a momentary signal to it so it can be switched on and off remotely ( more software request).

Thanks
Bill
 
While finishing up the code for the Volumite version I found that there was a trace missing on the relay boards (mfg error). New relay boards are being made now. Kits are being packed at the same time. they should be available very soon.

Another update: I have switched to Dale 1% resistors from the Phoenix MRS 1%. I am contemplating a "premium" kit that uses IRC 0.1% precision as well, but I need to work out pricing first.
 
AC1, I2C voltage requirement

I would asume you are sticking with 12v for the Joshua tree and I2C controler. Will the AC1/femento/Display require and aditional voltage? Not to beat a dead horse but how much current do think I will need for a complete ballanced Joshua tree / Darwin configuration.

Thanks
Bill
