    Hi, I'm also trying to figure this out. In my case it's to fit a graphics card in my HP elite 8300 ultra-slim PC with MXM slot (although I'm very likely to encounter a bios whitelist-wall).

    The guy you found on youtube also has a website (with some very cheesy copywriting), there's an option to preorder, but the site hasn't been updated in months: http://www.sourninja.com/dualwield/

    It seems to me the project is dead.

     

    I found some old PCB design on the notebookreview forum http://forum.notebookreview.com/threads/lets-figure-out-how-to-convert-internal-mxm-connector-an-external-pci-e-x16-box.407071/page-11

    The autor of the design warned there are some flaws in it - i think he said that his card would function only with default windows drivers, while delivering very low performance.

    You'll need a freeware program called FreePCB to view the design.

     

    I think the best option is to print a PCB locally, if we are able to get a working design. I'm thinking about contacting my friend who is electrical engineer to ask him to design a new PCB for me. I just need to know which pin connections are needed to make it work. Did you find any datasheets for MXM and PCIe pinouts?

    Yeah, the project seems to be pretty much dead by now. They didn't collect too much money on kickstarter (or whatever they used).

    Moreover it seems like they weren't able to connect a proper GPU to their Laptop (whitelist? or flaws in their PCB-design?)

     

    I got the PCB files Sompom posted on another forum. Fortunately the did not get removed by Dropbox.

    They are in the Gerber file format and are quite tricky to edit.

    I'll upload the file. Let's hope it won't get taken down.

    And I'm unable to access the file you uploaded for some reason...

     

    I might have some spare time next week. I  might sit down and create a spreadsheet with the correct pin outs.

  2. I have done some research too in the last couple of days.

    So I figured I'd share my findings and contribute a bit.

     

    1. Apparently MSI once had a working prototype of a PCI-E to 2* MXM

    We are trying to achieve the opposite and things have changed quite a bit over the last couple of years but it shows, that PCI-E and MXM share many things, MXM just has some additional features.

    Back then it was MXM Rev. 2 I believe.

    2. Some Chinese site is selling PCI-E to 1* MXM Adapter Cards.

    This demonstrates again, that an adapter is possible. This card doesn't seem to utilize the full bandwidth tho.

    3. Leap Computing Inc. requested a patent regarding a "Mxm graphics card adapter"

    Initially I thought they made a MXM to PCI-E adapter but it seems like another PCI-E to n* MXM Adapter.

     

     

    4. Some guy seems to have a kind of working adapter.

    He has made a short YouTube video demonstrating it.

    I made a Google Drive directory where I will save all of the stuff regarding this topic. Everybody is free to view / download the files.

    Now I hope to get hold of some PCB design files and let them be printed.

    If this works then I'll try to add additional functionalities. I'd try to get a video signal back into the laptop, so it'd be possible to use the internal display again / too.

    Unfortunately all of these links are down / don't work. Dropbox seems to have blocked the content.

    Could you please re-upload the files on another service? :) I'd really appreciate that.

    I'm particularly interested in the PCB designs.

     

    Thanks in advance (for your previous work too)!
