Win 7, Firefox, the first one opens a download box asking what I want to do  
with the file  I'm about to download, the second link opens the picture in a  
new tab like I'd expect and hope for.

Yes


Yes.  Looks good!

Are you just using a Dremel to make your cuts?  Or something fancier
like a small, hand-guided, milling machine?

Freehand Dremel with a carbide dental burr, on gold-plated FR4.  

I'm getting pretty good at it.

Yes ;-)    

I've never been terribly good at free-hand lines and controlling the
depth.  Perhaps there's an inexpensive manual X-Y table to be found?

Some sort of pantographic cutter would be fun. You could draw the
pattern 4:1 or something, on paper, and just follow that. No software
required.

Looks sorta cumbersome, and doesn't do vias.

I don't have a sewing machine. The dental burrs are cheap and last a
long time. They have a nice shape for carving copperclad.

What Dremel you using. Mine vibrates so much it is useless. Besides it
is noisy.

Best drill motor I have seen was from an old cassette recorder. You
could not feel or hear if it was running. You can certainly hear
Dremel. My neighbours propably too.

Re: dropbox link
Works good

OK, I should copy the "share" links and edit to add the "raw" thing.
And hope they don't break that too.

What's the output voltage and what efficiency did you achieve?

Input 24, output +-10 for logic and opamps, +120 at about 1 mA for a
photodiode.

I don't recall the efficiency, but nothing in that part of the power
supply gets especially hot.
