I figured that sticking to 50 volts and below, with 2 maybe 3 amps max as set by a series resistor, would make the circuitry simple enough for me.
Plunge EDM can be done using a simple servo loop where the insertion velocity is determined by the average DC current of the spark. That makes the setup very easy. Making gears, as in 2-d milling, would require some smarts to drive steppers or servo's. While I do have some computers, I don't have the smarts...
I figure it'll be at least a year or so before I'm in a position to worry about CNC stuff.

Pretty easy to get around that, just refine the search a bit, by using Advanced Search: "edm discharge" in the "all these words:", "dance" in the "none of these words:" boxes - I then get a page of 100% relevant links ...
I would try to make the line going across the plane split balanced, IE coming from the DAC signal reference ground and parallel to the output(s) referencing them, with as little loop area between the line and chip as possible to minimize coupling from the ground plane. This way there is minimal mode conversion (DM to CM caused by mismatched signal and return path reactances).
The balanced line will be a long loop in the plane of the ground plane unless it is "twisted" somehow or some other method of reducing coupling is used. What about splitting the ground line into two lines on each side of the signal trace? This way it is like two balanced lines (signal traces merged in the center) with opposing loops where the loops combine to null across the ground plane.

I have used three isolated ground and power planes with their own regulatrs and filtering. The all digital which is carefully connected to the d/a analog and that is EMI filtered and differentialy coupled to the analog output section.
By using three systems it is easier to keep current paths clear.
Ah, thanks. I've never used advanced google search, didn't know it existed.
I've been using the plus sign for logical refining.
Those features woulda come in handy when I was searching for epoxy preimpregnated fiberglass cloth, with "pamela anderson" in the none of these words category. I was not aware there was a following of her "before pregnancy"...

Yup. Tom's lecture/presentation was geared towards audience Q & A. I do the same with my presentations, as I believe presenters should not simply read from the screen, but embellish. Most audience members tend to read the entire slide long before the presenter, and then they check e-mails or play angry birds until the presenter finishes reading the slide.

Back in the day's of Alta Vista, even a beginner could do serious searches.
I do miss Alta Vista (I'm still a beginner)
I must admit, google scholar hasn't been very bad. I've downloaded 18 papers/articles on micro-wire edm. None of them were found using the normal google search.
Using google scholar also hit paydirt when it comes to skin effect, so many of the EM papers from the 40's and 50's are now out there to find. I used to be surprised to see what has either been forgotten, or just simply not taught in the textbooks from the 70's to today.

It is obvious Google is not any more a search engine, since a long time. Just some kind of a big billboard for business.
The worse is their attempt to deliver responses selected for our profiles, established with illegal espionage methods between Internet and our Android mobiles.
The result will be we will only get answers on things we already know or Google want to sell :-(
Not to mention what they decide to censor, entire Internet quarters in some countries.
On my personal opinion, Google and his absolute power and monopolistic position is "THE ABSOLUTE ENNEMY". The worse thing that happened to our Internet utopia and our dreams to share freely the human knowledge.
Big Brother.

You are entitled to you opinion. Yes, they collect information, and yes, I'll get directed ads.
This site also does that, but I cannot tell if it is a result of google, or microsoft, or the vendors I looked at.
Bottom line, is it's free to me. Somebody is paying for it, so the price of that power is the collection of information. While I'm not sure, I suspect that somewhere in the microsoft/google disclaimers I have to click "I've read and agree" before I can install their products, is my agreement to the collection of data. I'm not going to worry about it, I just enjoy the facilities available.
It's a tradeoff.

I think it is not my only opinion. If I refer to numerous convictions that the European court and my own country has fined Google. Google Pays the fees, but don't change his policy.

I don't care the adds, as you said, it is a free "service". I care the content, how Google is spying on us (big data), how they violate copyrights, make profits on illegal activities. You know, Android, you tube etc ;-)
Same position: I don't care the adds, and... we are not allowed to make comments about the moderation.
