Powergate said they would have more 700h in June.... But that a long time to wait!

If you order something from powergate call their sales office. Apparently they do not update their web pages well and I was able to get some 500l for $3.10each instead of the $3.95 their web site showed.

That and I believe Mouser still might have some in stock, but mouser was more expensive. I ordered 5 of these from OnlineComponents yesterday too. I have 4 brand new LDD-700hw (the wired version) that I'll sell. If I can't sell them soon I'll just return them.

I remember this being asked before, but I don't remember the answer. But can you mount the ldd-1000h's and ldd-700h's on the same pcb?

Yes all the 'H' series are the same size, 'L' series ones are different sized (and they only run 36V)

Just to make it clear to myself on how to wire my LED set up.
I will have 2 groups on LEDs. Each powered by 2 LDD 1000 and 2 LDD 700, 1st for XT-E, 2nd for colors. Each group is the connected to a 250w 48v 5.2a power supply.
So in total I will have 8 PWM wires which I understand I have room to plug into the Arduino Mega.
Arduino Mega will be powered by it's own small PS (9v 1a) through that round plug.
From reading through this thread I gather that Arduino need to share common ground with LED power supply. Would I just have a wire from each of the 250w PS running to the Ground pin on Arduino?
Here are the power supplies.
Driver PS - can't seem to link to the milad's site but its the 250w 48v 5.2A DC Power Supply

Not sure why Im having such a difficult time downloading the gerber file. I saved it and it saved as a zip file. So I extract it and then try to open it and it will not open it. I have WinRar but is there another program I need in order to view these files and so I can send them to the company who creates these boards?

You have problem with the zip or problem with the files within the zip? If you need to order the board, just send them all the files within the zip, they'll figure it out the rest.

Those are the gerber files, you have to use a viewer to see them. Eagle does not open those. You can use a program like plot view, or just upload them to this site:
http://www.gerber-viewer.com/
Also, was that all the files that were there? You're missing one. There should be one with a GBL file extension.

Yeah whenever I try to open the files after I've extracted them this pops up.
Are you trying to edit the file or just view it?

You can view them if you want, but you normally don't open those files. The files that I use to design the board are actually .sch (schematic) and .brd (board). Once I have decided the board design is finalized, I run it through a CAM processor (computer assisted machining), it creates various files that contain the information for each layer of the board, whether its the top, bottom, silk screen, drill guide, etc. When I run the board through a CAM processor it creates a ton of files, I select the ones that are required to send to itead and zip them up. That is what you downloaded, send that whole zip to itead after you place your order.
However, like I said, I noticed you are missing a file. You should have:
*.GBL
*.GBO
*.GBS
*.GTL
*.GTO
*.GTS
*.TXT
You are missing the GBL file. I doubled checked, it's in the package. At least the one on my computer I uploaded.
If you really want to see the data the files contain, upload the entire zip to the online gerber viewer I just linked and you can view each file's data. It will look weird though, because each file is effectively a different layer of the board.

You have a file extension associated with those programs then. I'm guessing you selected adobe to try and view that file and had the option to always use that program to open those extensions checked.
You can change it back. You can verify the file extension is correct by going to folder options, going to the view tab and unchecking the box 'hide extensions for known file types'. Then you will probably see it is still a GBL.

Did you have any luck with this? I have been excited to see what you come up with.
