New eControlBox (based on Ohio-Ed's)

Thanks to the wonderful collective resources of HBT, and especially Ohio-Ed's control panel thread, I've reached a major milestone in building Rev2 of my eBrewery. The panel guts are O-E based, but instead of using a BCS, I'm using a LabJack U3 USB i/o device. The panel cover is rather sparse because the UI is touchscreen. I've elected to only populate hardware UI devices for the e-stop-latch function, a master keyed power switch and two status lights. I may mount a second e-stop right on the table. Very exciting, after pinging everything out the first energize was at 5am this morning to test the e-stop and reset functionality.

I'm using LabView right now because I have developer access, but began testing in C++ and VB. LabView has a StateChart module that is quite suited to the brewing process (or most industrial control) especially because brewing is essentially a "waterfall" model. ie. we don't normally re-enter previously completed states
