[Q] Using Galaxy TAB 7" With External Hard Disk (P1000)

Does anybody know solutions for using external drives in Galaxy TAB 7" ( P1000 ) ?
I 've searched some items, i found an " USB Server " or " Print Server " but they were supporting under LAN connection (not WIFI or Wired). Related search: http://s.dealextreme.com/search/usb+server :good:
I know that, P1000 does not support to attaching any usb flash or hard drive via 30pin connector adaptor.
I think, For the solution we must use an external device/adaptor that has been external powered and output connector has micro usb.
Did someone use to own p1000 with ext. hdd ?
Does any solution, idea or suggested item ?

You are right, this works. You need a kernel with support for USB Host and rooted ROM. To mount the external drive you can use the App "USB Host Controller".

It stills need external power source!
I built my own otg cable with external power source.

Something like this.
Then with usb host controllers works great But is sad It can't suply power. It's so bulky cause I made ith a hub xD

Making a cable for rooting Chromecast.

Hello guys,
I got myself a Chromecast i need to attempt to root.
I dont have a cable, and i cant be bothered to buy one, when im pretty sure i can make one.
I just need to be sure i have the right stuff.
This diagram to follow, but i dont wish to make it like that.

Here is what i have:
Since the 100K resister on the diagram, is if you add the micro USB to the loop straight away.
The plan i have is to connect my two female USB together, and us the male usb plus and minus for the power charging. But does it only use the 5v for charging?
The finished plan would be as said abouve, and then plug the cable provided with the chromecast into one of the USB, and USB pen drive with files into the other.
As far as my own theory this should work, without the 100K resistor needed. Anyone have input. I have searched high and low, and i am sorry if this has been posted before.

That should work - just make sure all your connections are secure, nothing's backward or shorted, etc.
I didn't need any resistor when I combined my Y-cable and adapter, so I don't think Chromecast cares.

I made this same cable without a resistor for rooting ChromeCast. Worked just fine.. Bhiga was slightly wrong, there are two pins that do need to be shorted, the diagram is right... I didn't feel like soldering a short on those tiny pins so I just ran a long wire between the USB micro and the joints that I soldered.
Took about 2 hours to make the cable.
I'd be sure to use a continuity meter to make sure you aren't shorting any other pins

Otg stick for nandroid backup

Hey guys,
i am planning to Experiment with custom Roms/kernels etc. But to Start you also have to make a nandroid backup you now ;P and i don't want Them on my internal storage because they are so huge. Now my question: What otg stick can you recommend me? It should have fast r/w speed because i dont want to wait ages to finish nandroid backup. It should have 32gb less is not enough and more too expensive.
Has the g2 USB 3.0?
Thanks in Advance

The G2 does not support USB 3.0 speeds, but it works just fine with USB 2.0 anyway (it's not like the eMMC Flash-RAM inside the G2 or any other modern smartphone is gonna be capable of reading/writing at USB 3.0 speeds anyway).
I suppose in the long run it doesn't really matter which USB stick you choose as long as it has a microUSB connector on it - no sense dicking around with an OTG cable when you can buy sticks like this nowadays and things are much easier:

I got one of those last week (64GB version), works great with my G2 (ROM/kernel info in my sig). Speeds are roughly as expected, maybe 30-40MB/s reads and 20-25MB/s writes, it's fast enough for OTG operation since it's not plugged in constantly. Having the normal USB connector on the other end makes it a breeze to move files back and forth from the PC to the phone, etc, in situations where I may not happen to have a microUSB cable handy (rare thing since I carry such a cable and a charger in my cargo pants with me constantly).
Since I use Mi2Raw with my G2 to capture raw sensor data instead of "pictures" and they're 25MB each it does tend to use up a lot of space fast so, it's nice knowing I have the SanDisk stick around to move stuff over, and yes I do my Nandroid backups directly to the stick as well (currently has like 12GB of backups on it just in case).
Got it for $25 at Fry's recently during a sale with a "promo code" for being on their email list, works for me. 32GB version of this stick or a similar one should be $20 at most if you shop around.
There's a bunch of these types of sticks available nowadays, I highly recommend them unless you prefer to use an actual OTG cable (I can still use that option too since this has a full size USB connector on it, obviously, and I do have an OTG cable).
Something to get you started...

Has anybody found a *tiny* USB-C OTG adapter?

With my Note 4, I could keep a tiny OTG adapter (pictured in the link below) in my wallet to give access to USB devices...
https://ae01.alicdn.com/kf/HTB19g5f...TG-Adapter-Converter-into-Flash-Drive-For.jpg
I can't seem to find a similar device for use with the Note 8.
Has anybody found anything like this?
Cheers,
Steve.

Perhaps not as tiny but the Note 8 comes with an OTG adapter used for transferring data from an older phone to a new one.

Yeah, I know - I was really wondering why there aren't any OTG adapters in the nano flat style. That's what I'm really after.

THIS is the smallest I've seen.
Well, there is another but the listing just seems a little dodgy - Clicky

I bought a usb 2.0 to C OTG adapter which did not work at all, and a 3.1 A to C which does so that may need to be a consideration beyond just the physical size.

I would have gone with the second one if the picture had actually been of a USB-C interface, rather than Micro USB.
If it can't fit in my wallet, then attaching it to my key-ring (with minimal size/bulk) is a reasonable alternative.

I keep both of these in my wallet. Type C to micro USB and a micro USB OTG adaptor.
Got them from Gearbest and/or Banggood.

It's nice to know that works - I ordered exactly the same from Gearbest a week ago.

Samsung DeX Laptop from a Pi-Top V2

Hi,
Just been tinkering with a Pi-Top V2 and some cables/other bits and now have a Samsung DeX laptop with a 14 inch 1080P display.
Needs a few more bits before it's more polished but thought I'd post my initial project and will post updates as they occur.
More details on the Pi-Top forum where I describe what's needed to make it all work.
Ok, have added the following enhancements:
1. Dual USB-2 hub - provides 2 x USB ports at the rear where the Raspberry PI middle ports would be
2. USB-C socket - this means no wires come out of the unit - a USB-C to USB-C cable (with 4K video capability) is used to connect the unit to the smartphone
To do
1. See if I can get some speakers into the unit or use extenal pocket USB speakers
2. Alternative would be to somehow breakout the audio from the HDMI signal and feed that to an internal amp and speakers - not sure there would be room for the electronics but will take a look

This is really really great! Can't wait to see how this project develops!

Can you post a link to the pi-top forum? I would like to follow this project too

That absolutely awesome. I was just about to buy an older laptop and gut it.

Details
I have checked out the link on pi-top. You have done an amazing job and appreciate your sharing.
I really would like to build this for myself.
Can you post or send me pictures if you have any from before you threw the insulation tape on? I wanted to get a better look at the parts where you have to cut the usb cable and connect to the GPIO.
Also can you send me the names of the parts you used (part numbers) so I can purchase from Amazon. I have a list made, but want to double check since your set up currently works.
Thank you.

Subbed to this thread. I think I am going to try and do something like this!! I have a dozen or so laptops that are in various forms od not functioning that I can gut.

But that color!

I burnt the pi top screen trying to do this :crying:
