Make your own cables

So far I have learned how to make a USB host cable and a universal charging cable. I have shared this in a few post but I figured it would be good to have them all in one place with a diagram.

I will update this drawing as I learn how to build the other cables.

Thanks goes out to pokey9000 for sharing how to do the USB host and nudging me the right way for figuring out the charging!

Update:
I guess the titles of each is not enough to properly relay what each does so here is a quick description of each.
1. USB Host - Puts the Tab into host mode so that you can use items like thumb drives and keyboards. If you want to use a USB powered hard drive, you will need to use a powered hub.
2. USB Host w/ Power - Puts the Tab into host mode but also allows you to charge the unit at the same time.
3. Universal Charging - For making a 30-pin cable that will let you charge your Tab off any 5V source so that you don't get the red X over the battery. When doing this, data transfers will not work.
4. Universal Charging Inline cable - For if you don't want to buy a 30pin connector or cut up your OEM cable, you can put this in line with your OEM cable and use any 5V source.

It is my first time linking a picture which you can't just upload, you need to link to an existing online photo.

I think I fixed the problem use ImageShack but if you still have issues viewing, use the below link

okay a few questions again..

Would it be hard to make a usb keyboard work on the tab (like cutting up the usb cable and replacing it with a 30pin dock connector?)?

And how much effort would it take to create a hdmi out? or a normal video out if possible..? Because I actually need an old video out port but on the samsung site is says that the video out represented is not compatible with the 10.1..

and where do you solder everything on? I've yet to find a picture of the 30pin connector which tells you where to solder..
Where would I solder in this image? http://shop.kineteka.com/images/thumbs/0000564.jpeg
Or should I just get a tab-out like this:

If you want to take a USB keyboard and make it work, the easiest thing for a beginner would be to get the tab breakout connector and then solder the wires as shown in the diagram. If you don't have a female connector, you can cut off the male connector from the keyboard and just match up the colors.
Only get the other connector if you have a way to ohm out the pins so you know what is what, have a good soldering iron with a fine tip, and also have a steady hand. I got my connectors in the mail last night and I can probably take a picture and specify the pin layout if you like.

As for the HDMI, I am not sure yet. Seems like either no one has an adapter or if they do, don't want to share what the insides look like. For the older tab, it had one pin for standard video, but HDMI has 19 pins so either a lot of pins on the 30pin connector get reassigned in some way, or there might be some type of chip that does the conversion. I don't know enough about HDMI to make a proper assessment at this point. I hope someone with an actual adapter will chime in soon.

From a portable battery, like one of those from Zagg, that supply 1A.

Not a good idea. Those Y cables just short together the 5V from both plugs, assuming they come from different USB jacks on the same PC and so the same power supply. If you do this with the Tab and a USB battery pack, the battery will feed power into the Tab's USB host power supply when it turns off in sleep mode.

I'm going to create these boards and order them so if they work i can just share it with the community. You guys won't have to do anything besides install the parts or something.
