MOTM

I think a totally seperate power supply for all three voltages is 
the way to go.  I don't like the idea of getting digital noise on 
the supply lines for the analog modules, and I don't like 
wallwarts.  On the subject of LEDs vs. LCDs, I have no particular 
preference as long as they're all the same.  I have a really cheap 
LCD handheld oscilloscope that I was thinking of trying to adapt to 
a MOTM module as well.
