If you're asking me, i didn't. I was referring to the ebay link in the third post.

Kind of makes me wish i hadn't hacked up my webtop to work with the Otterbox

before I read that post, I was looking around the forums and the web yesterday well into the night. here are some of the things I've found that might be relevant to everyone (and it might possibly be cheaper, though more diy).

Micro USB stuff:

Here's what I am thinking about doing:

The HDMI certainly looks like it may work but the reason I didn't buy that product from ebay a few weeks ago was because it was $50. Now miraculously, it's only $6. Maybe I'll get that if the USB cable I just bought that was suggested works a few posts back.

This micro usb extension cord explicitly states that all 5 wires are connected (compatible with droid bionic for the purpose of docking with a case on the phone):

I bought the HDMI extension cable and the USB cable above. I have a lapdock so I'll post if it works.

The HDMI cable seems to work. On the lapdock, with just the HDMI cable hooked up, it functions like it was it's an entertainment center.

The USB cord will need to be modified a little bit. I can't get it to seat right on the USB jack of the dock. I'll need to shave it down a bit as it doesn't sit down snugly.

I ordered the USB cable and experience this same problem, though I am waiting for my hdmi parts to come in (by April 6th I should have all my parts...). The cable itself works flawlessly as a micro usb extension cable when connecting it to the computer.

again as mentioned in the other thread, you want to be careful with the 5v coming out that micro hdmi port. for connecting back to your phone would be no issue, as the phone charges using this voltage, but hooking the lapdocks micro usb up to a host device probably wont appreciate the 5v coming back up the cable, where normally the usb device would be pulling power from said host, not providing it.

one suggestion is to just clip the red wire inside your micro usb cable/adapter.

btw the adapters i use do fit snugly side by side, without modification.

I've been following this thread for a little while now, and I wanted to share something I found.
I was looking at the Motorola Travel Webtop adapter. And I was curious to see whether it could be tweaked to suite our needs. I naively thought/hoped that I could flip the connectors in the device to make a small adapter to connect the Atrix to newer Lapdocks. Unfortunately as you can see in the pictures below (sorry not enough posts to link to the pictures) the two connectors are connected via a PCB not wires or a ribbon cable. Although I still have high hopes that I can de-solder the HDMI and USB connectors, and use a small length of flat ribbon cable to connect them and then re-positions the connectors in the case, to build a micro adapter to use the Atrix on the newer Lapdocks. Should this fail this will at least prevent others from making the same mistake, and solve the mystery of what's really inside the Webtop Travel adapter.

Do any one know if this Micro HDMI Cable would work for Lapdock.

http://www.ebay.com/itm/1-Feet-HDMI-...ht_1149wt_1187

Description says for Asus tf201 MEMO ME171.
I believe all Cables are standard. Can this used to Atrix 4g with Lapdock?
I have otterbox case for Atrix and don't want to Remove cover everytime to plug in Lapdock.

Looks like it should work, the USB cable is what you have to watch out for. Go for one that has all five wires.


Thanks for reminding me of this thread, I meant to reply with my findings, so here I go:


Whatever you do, don't buy that micro hdmi coupler from ebay! I purchased in February 25th! It never arrived, even though the seller sent it twice. I lost six dollars (Shipping was supposed to take a month, so foolish me giving the benefit of the doubt missed out on the ebay buyer protection)

I decided to buy the deal extreme hdmi connector everyone always refers to, and finally arrived the last day I was at college (mid May). The USB cabled I mentioned I would buy works perfectly with a standard hdmi coupler, as does everything else (except for a separate hdmi cable I bought, but that's another story since it's not related to getting the phone to work in a case). The only problem I had was that they did not fit properly, so I had to delicately shave off a lot of the plastic coatings.

As for the aforementioned hdmi cable, I wanted to use the lapdock as a second or third monitor for my laptop, so I bought a displayport to hdmi adaptor, and an hdmi cable. When I received it, my laptop could not recognize it. I thought the adapter was broken, but then realized by $2, 10 foot hdmi cable was a P.O.S. An order from monoprice fixed that problem, and now the lapdock works perfectly as a battery powered portable monitor!
