I didn't realize until your reply that my phone auto-corrected
"too low" to "two low". How embarrassing.
In any case, congrats! I'm really excited to see the whole beast
come together.

Yeah, if you run some of the less intelligent
ones with two low a
load, the duty cycle on the switcher shrinks to near zero, which
means lots of sharp pulses up/down next to each other on an
inductor. The end result is not nice. The smarter systems will
just hold off for a period if they detect an insufficient load;
the even smarter ones will switch in a dummy load automatically.

Well my new caps came in tonight. They were kind of odd values so I had
to order them. I put them in, assembled it and success! DC light right on and after
getting the baud right, a prompt!
