Another alternative way of making the PCB's is to using the ExpressPCB etching service:http://www.expresspcb.com/
On my first layouts of AMC I used their software to design the layouts but I didn't used their on-line service. Instead I printed the layouts on paper (PDF). But as R-eng reports, the quality of their boards are great, so if you can affort the extra money for ordering from them, you will be happy with the results. And they use double-sided PCB's too!!!
I would give my old expresspcb layout plans but instead I prefer to give you the ones that R-eng made, and used to actually order the boards. They have a few modifications most of them to take advantage of the double layer PCB boards!!! Also there is a small size increase of the fan used on DSMhb to 92mm. I have run a quick check on them and they look correct. Thus we have seen his video with these boards made and working fine!
Here is the expresspcb files which include the board you see in the picture, and another one which would be a basic AVR-DSMhb system.
And here is a short description from R-eng about the ordering he made to ExpressPCB service:
"I had the large board done per their "standard board" method because it was the most cost effective to produce. Their "mini board" method only supports ~3.5" x 5" size (x3), and only 1 design. That was not feasible.
They do allow you to cluster multiple designs into 1 board, and the user then needs to cut it into pieces, like I did. I just outlined the individual boards with a rectangular thin trace as a cutting guide, as you will see. There is no minimum board count, one is ok. But it is more costly because of the setup fee, which if it could be spread over more boards, really reduces the individual price.
I ordered 2 boards (one for a friend) and it was nearly $200 USD. Not the cheapest, but I think the quality is very high and I am pleased with the results and turnaround. And the boards are dual sided as standard...no jumper wires to solder. It made for a very clean programming jumper board which you can see in my pictures.
I increased the cooling fan mounting holes to a 92mm unit, completely centered over the Mosfets."
BTW, I repaired my Sprint-layouts of AMC1.5 and Parallel_Lcd boards after R-eng suggestions... post7978.html#p7978
