Cool news!!

Maybe add a separate DC supply and just use the game AC GI lines for sensing what they are doing?

Quoted from herg:

That would work, but it would be more expensive.

Once you add up the parts premium you have to add to deal with the heat/amperage, a ten dollar power supply doesn't seem like a bad tradeoff.

Quoted from herg:

It's worth thinking about. If you include the smoothing caps, the parts on my current board add up to about $10 - $12. Do you have a $10 supply you could recommend?

I've not got a particular 9V one I buy, I usually pick up the 12V ones from amazon or ebay, like this:

http://www.amazon.com/gp/product/B002FH54L6/ref=oh_details_o05_s00_i00

here is an example of a 9V one I found during a quick search:

ebay.com link: 100 240VAC 9V 5A Switching Power Supply Metal Case WD6

Quoted from herg:

The 12V one is only 2A, and the 9V one on Ebay is $27 after you tack on shipping, plus it's only 5A. I'm shooting for 10A capability. Then, you have to add a cord and hook it into the service outlet. I have looked into the idea, and I'm convinced it not as easy as just buying a cheap DC supply, nor would it be as elegant.

The exact one you are looking for exists, I just don't have the time to do the legwork for you.

Whichever method you end up going,I'm excited to see the end product. This is one of the puzzle piece that has been missing.

Not trying to step on your toes, just help out. There was no need to play coy about not already having a power supply.

Herg, is that Protel?

I can't find my Protel 99SE disk anywhere....

Quoted from herg:

It's KiCad. Pretty darned good for an open source layout package.

Thanks! I'm gonna check that out. I'm not really digging on Eagle. I only tried it because of the missing Protel disk.
