Well it's getting to crunch time so I need to pull together what I have so far.  The voltage regulation circuitry is now operational and I am getting -5mV rms noise on the output even with 10 amps of current and bad wiring.  I have laser cut the enclosure and the supply will be inside the enclosure for the presentation on Monday.  I will be spending a lot of time in the open lab to add the last few features I need and hopefully get my DAC and ADC to work with an Arduino Mega.  If not, I can use the built in stuff, but that is not a favorable situation.
