Hi all,



Some weeks ago, Mike Millers gave is kind permission to publish his 

homebuilt version for a Rotax voltage regulator

Feel free to comment or ad complementary data.



FWIW,

Gilles - thanks for the reminder. I downloaded the file package (chiefly as an academic exercise at the present) but I was unable to open the PCB file with any of the versions of EAGLE now available for my Mac. Turned out it was created in a very elderly version of the EAGLE PCB design software. I’ve since had help from various folk (including Mike Miller) to convert the PCB file to a version that can be read by current versions of EAGLE. If there’s somewhere I could post the updated file that could be accessible to others and is likely to stay available for the foreseeable future, I’d be glad to know of it.

Rowland and all,     

Thanks for your offer.     

I was able to open the files with a free version of Eagle I       downloaded last week, and converted them to gerber files that can       be read by any CAD program - and any vendor for that matter.

       But I'm not at all familiar with Eagle so I'm not sure I did it       right.

       So if you or anyone can provide verified gerber files I'd       willingly publish them so one can directly order from a PCB       vendor.

       By the way some times ago I had very good success with several PCB       orders from a far East company, at a price of $5 for 10 pcs       (100x100 mm ~4"x4"). Not much more expensive for larger       dimensions.     -- 

       Best regards,

       Gilles

Hi Rowland

I was able to open the original file in a PC version of Eagle.

I'm sure you already know this but for the benefit of others, the only

issue I noticed was the size.  It came up as 4.00 x 3.93 inches (101.6 x

99.8mm).  If it was resized so that it was 100 x 100 mm or smaller then it

can be sent to one of the cheap board houses as a prototype board and

manufactured for as little as US$21 for five boards delivered via DHL.

This was from JLCPCB who seem to be the cheapest at the moment.  I've used

them for one board and they seem perfectly up to the task of producing a

simple board like this.

Gilles - I have sent to Bob the (several) files that kind folk converted for me to be readable by the current version of EAGLE for Mac. I expect he will announce when they are loaded alongside the other files for the Miller regulator.



I’ve had a look at the export possibilities provided by my version of EAGLE (9.6.1) and the file format possibilities do not include Gerber - see attached screenshot. Maybe someone can say if one of the options shown would be more universal than a .BRD file. Or once the .BRD files are put up by Bob, folk can play with them and try translating to Gerber.

Hi Rowland,     

Thanks for that.     

If I recall correctly I tried the CAM option(s) to generate the       gerber and .drl files.     

Will post them on the webpage for anyone to download.
