Very cool build RMM!

Hey Werner, try using Mattaus’s CAM generator
File is here, just copy into your cam processor directory, then tell it to open the brd file, then run project…then zip all the .* (capital letter files) files (the .GBP and .GTP files are the paste files for OSHStencils), and upload that to OSHPark
https://www.dropbox.com/sh/mnqwk08b9p4d6pu/AACkJxVSqBmWi9-rlSBAGuZTa?dl=0
That is the directory of all the custom library files Mattaus has given me and his custom CAM processor
There is not much need to go through the extra step of generating gerbers, unless drc errors are causing oshpark to reject your brd (or you want to change a part outline silkscreen without actually editing the part).
or OSHPark shows one thing but for some reason the fab house runs em differently
(like what happened to Werner)
I have uploaded a few .brd files I found in peoples shared project folders, OSHPark rendered them all funky, traces extra wide and shorting. blah blah…when I converted to gerbers, they came out just as I uploaded them…sometimes their stuff goes squiffy…not often but it happens
Added the Teeny10 and MS
The fab makes occasional errors whether you use brd or gerbers. I’ve had equal fab errors with both.
I’ve noticed that too. Honestly, if you run drc on the boards, you’ll see the problems causing it. You can only have so many drc violations before you start getting problems. Gerbers mush everything together and can hide some errors. When starting out I can understand ignoring everything to just to get a simple pcb made before you really learn eagle. But it works against you, makes designs harder if you continue like that.
I dunno about all that. Generating Gerbers is definitely the tried and true way. Even Gerbers leave room for error, BRD files leave a lot of room for error.
Someone asked for a single mode single 7135 10mm driver…that is why I made that one…can’t find the discussion though
With the turnover these days it’s probably on page 20 by now.

As long as one isn’t using gerbers because oshpark is refusing the brd due to a ton of design errors. Most fabs don’t even accept brds, its supposed to be helpful that oshpark does. The brd isn’t sent to the fab, they generate gerbers with eagle 6.6.
We are currently processing uploaded Eagle BRD files with Eagle CAD version 6.6, and have confirmed compatibility with all Eagle versions up to 7.1.
I got answer from oshpark and its like wight has said it before, fab messed it up, their files look good. No big problem anyway but good to know it wasn’t my fault.
I used gerberfiles before for itead but I like how easy it is to just upload the brd file and see a preview…

gerbers in a zip do the same thing
Get a program called grbv and it will generate a 3D image of your board as well, you can even change the default skin to the oshpark one and see the way your design will look as well
Like RMM’s Moonlight Special V2 8x 7135

P.S. RMM when you zip the files, don’t include the revisions in the zip…only the files with capitol letter extensions
OSH Park seems to have added a cart system.
Lol. Yeah, too many revisions...too little time!
I tried to run that 3D rendering program but I don't have OpenGL 3.0, so it was a no go.
Moonlight Special V2 8x7135 Driver
This driver was originally an idea I had when I got sick of building 16x7135 drivers, then having the moonlight be high, unstable, or not work at all. After my failed attempts, JonnyC tweaked the STAR firmware for dual output. I built quite a few cutting traces and using a jumper on the normal 105C boards, then Mattaus helped me create the first version of this board. This is his board, with a few tweaks, and a nod to all of those who have inspired me and helped me down this path. I couldn’t have done it without the help from many here! Thank you all.
Please note that this exact revision is untested, although I am 99% certain it will work.
How does that work? I see a second diode. Does that help the moonlight mode? Or is that the Zener I have read about?
Moonlight is pwm on a separate pin to only a single 7135.

The second diode marked "Z" is for an optional zener diode, for multi-cell use with multiple LEDs in series or an MT-G2.
Thanks Halo and RMM.
The circuit is hard to see in that sort of picture, but I did begin to see what the diode is for.

The Zener will dump excess voltage beyond their breakdown voltage (normal diodes typically only conduct forward). If you put 5v on the “side with a line” of a 4.3v Zener it will attempt to dump 0.7v. Assuming you have a strong 5v source, the Zener will promptly self-destruct. Thus we use a current limiting resistor between Vsupply and the Zener’s “side with a line”. The other side of the Zener connects to GND.
In order to get your 4.3v in this case you must connect whatever you want to power with 4.3v to GND and to the “line side” (Cathode) of the Zener, eg between the Zener and the limiting resistor. If you test between the other side of the limiting resistor and GND, you’ll find that remains at 5v (or whatever the input voltage is).
Skimming the pictures here may help:

Many of you experienced Eagle gurus may already know this, but I've found Eagle's built in ULP "cmd-draw" to be especially useful. It can draw wires, polygons, move items into locations, or place vias in circular or even elliptical patterns. It will even name the vias for you, so you don't have to go around and name 12 vias "GND".
I was placing them manually before I found this, which requires forethought, attention to detail, math, and geometry. These are all things that I'm sure Wight loves to do, but I'm not very good at any of them!
