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.

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.

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 . . .

Easy name to remember ExpressPCB, expensive but fast service. Easy to use software. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=439625#439625 ________________________________ Message 6 _____________________________________ Time: 01:16:53 PM PST US Subject: Re: AeroElectric-List: PC board fabrication From: Graeme Hart 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'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.

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.
