Well got bored today so decided to write a little tool to help myself and figured I would post it here if anyone else wants to use it.

Gets pricing info from MTGOX and I will be adding more in the near future.
Does multiple currency's for the value calculations.
This has been tested on Android and IPad and should work on other mobile devices.

I just grabbed one of these hubs to see how it would work - http://www.ebay.com/itm/251342525547?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

I like the layout of the ports, you could easily fill it with block erupters.

Note that this hub requires some modifications for mining use

1) bypass the power switch or rewire it with heavier wire, the original wire will cause significant voltage drop and heating at 3+ amps
2) desolder the tiny barrel jack and just wire your power supply directly, it will probably melt at 3+ amps
3) desolder the red usb wire coming from the host pc to the pcb, this will stop any voltage from flowing backwards into the pc, there are no protection diodes on the pcb
4) solder a 47uF capacitor across the VCC and GND points that are now free on the PCB, the hub "crashes" and stops working if you don't do this step (it worked fine with a usb keyboard but plugging the miners in caused it to stop functioning until power was cycled to the hub)

So if you feel like tinkering, 5 minutes with a soldering iron can net you a hub at $1/port shipped from USA
I have only tried it with five BF1s so far, full load test to come when I get some more time
