Can you provide a web link?
I assume that the power increase comes from increased efficiency of your new rectifier/regulator
design, not from the PM dynamo. I would be interested in testing
a prototype in my Rotax 912 powered RV-12 E-LSA. Although my rectifier/regulator
has not failed . . . yet, many others have as reported on VansAirforce.

Yes, improvements in component capabilities
and performance . . . and market forces . . .
have encouraged us to look at R/R technologies
for the full line of PM power conditioners.
We have every expectation of offering a product
with greatly improved reliability. Improved
performance is a most welcome side benefit.
Rotax 912/914 is the largest PM system in
wide usage so I'm intently interested in
getting my hands on parts needed to craft
a test alternator that I can run on the
bench.
Once we have flightworthy POC devices,
we'll be looking for opportunities
to do field testing.

There are several. My personal favorite is experesspcb.com
who offers a proprietary but VERY capable ecb layout software
package for free and quick-turn (3-5 days), mini-board service
for a flat fee. They've been my prototype and production supplier for
over 10 years.
Similar services have been cited here on the list but I'm
not familiar with any of them . . .

AeroElectric thread about PC Board House:

Elecrow in Hong Kong, inexpensive but takes a month
OSH Park, reasonable US company. Easy name to remember
ExpressPCB, expensive but fast service. Easy to use software.

I use oshpark.com for small boards, they charge $5 per square inch and you
get three boards for that. The boards are purple, double sided with solder
mask, silk screen and gold plating.
To do larger boards I have used both dirtypcbs.com and elecrow.com. Check
their sites for pricing but it is around $14 for approximately 10 5cm x 5cm
boards and $25 for approximately 10 10cm x 10cm boards. These boards are
double sided with solder mask, silk screen and lead plated. You can choose
from about 5 different colours.
OSH park are made in USA, the other two are in China.

I'll add another vote for OSHPark. I've used them a lot and been very happy
. Only once in perhaps 40-50 orders was there a production error, and they n
otified me by email before the boards even arrived, so I didn't waste time o
r components. Replacements came very quickly.
If you use Eagle for board layout, they'll accept your design file directly.
All other EDA packages can simply export industry-standard Gerber and NC D
rill files and upload them in a ZIP archive.
OSHPark charges $5/square inch for 2-layer and $10/square inch for 4-layer, w
ith free shipping. 1-ounce copper only. Your board has to be pretty big be
fore any other US board fab can compete on price, and they beat many of the C
hinese fabs (and are much faster). Boards typically arrive in about 10-12 d
ays; my most recent order was submitted on 3/10 and it was shipped today.

CadSoft EAGLE is very popular among the Open Source Hardware and "maker" com
munity, but I found the learning curve too steep for my limited patience; it
's a very complex program. EAGLE's free hobbyist license allows 10x16 cm bo
ards with up to six signal layers. http://bit.ly/1bj6Dr5
I switched to DipTrace and have never looked back. I found it much more int
uitive to learn. It's also a commercial software package, but their free "n
on-profit" license allows two-signal-layer boards (unlimited plane layers), u
p to 500 pins and no limits on board dimensions. There's a nice set of vide
os on the website explaining how it works and a useful PDF tutorial document
. http://bit.ly/1DDr26l
There are many others; I'm sure someone will chime in with more options.
