the s4 had problems for me. I have 4 s3's that work with that modified dock. but I have tried several s4's and they didn't work with my dock. ended up buying a different one for it.

another thing is the kernel and os. most of the custom kernels don't work right. I have a custom rom but it is TouchWiz based and stock kernel. other combos didn't work.

Anyone can mod mhl cable to HDML connection kit successful, on Note 3 android Lolipop ? In my town, the resistor 40.2 is not real. I use one 33 kohms and five 1.5 kohms, OMG i get to smart dock mode :laugh: HDMI work but OTG none. What should i do ? :silly:

Hi !

Just another Question, if i simply solder the 5V / GND / D+ / D- to a MALE USB Connector without touching the 1k Resistor, would i then have a working HDMI + USB slave cable (slave == normal USB mode, e.g. connecting to a PC for file transfer) ??

Greetings,

Hi all I have been looking at this with interest.

What I am trying to do is make a cable / connector block, that will plug into a Samsung S4 phone.

I am looking to get HDMI out and a USB mouse in at the same time.

Can this be done?

Hi,

I've order a 5 in 1 OTG / MHL adapter but it won't charge my device, would you please let me know why? (device S3 I9300).

In addition please let me know if I should download any new ROM or Kernel.

Thanks
[Galaxy S III Accessories] Amanoo:
I just found out that the Perseus Alpha kernel is supposed to support this. If you're not afraid to use custom ROMs/kernels, that might be a nice kernel to flash onto the phone and keep it updated while retaining out beloved OTG+charge mode. I'll check it out today and see if it's what it's supposed to be.
[Galaxy S III Accessories] jlook73:
Thanks for sharing

I checked components of smart-dock with your pictures.

I attached it~~

SiI9292 converts MHL to HDMI format

FE1.1s operates as a USB hub

- channel 1, 3, 4 to external USB ports

- channel 2 to PCM2704 USB DAC(audio out)

PCM2704 decodes USB data packet to audio signal

RTD2120 checks Power source from micro-USB port (with ADC and GPIO)

and manages other IC components (Only GPIOs and ADC ports are used)

2 LDOs

6 port protection ICs

1 switch(Q4) IC but system don't use it (R122 is NC)
[Galaxy S III Accessories] TheBlackCat13:
Three, possibly stupid, questions:

1. Can anyone tell how the pins from the phone are wired to the parts on the board?

2. Is there something akin to the SiI9292 in the normal MHL/HDMI adapter?

3. What do you think the key component that has been missing so far is? From your description and the pics I would guess it is either the RTD2120 or the R28 resistor (or both), but I am far from an expert, and am still not 100% clear on what the RTD2120 does.

hi guys, i have been trying to make this cable, i tried adding a 40.2k (39k + 1.2k) resistor but it wont work. tried it on my galaxy camera, if i add the resistor, i can charge my galaxy camera but otg function wont work, if i remove the resistor, otg function works normally. the gcam and s3 (international version) has the same specs, but i dunno if it has the same table for resistors to work. who is on the international version of S3 and got it working with JB 4.1.1? btw, my gcam is still on 4.1.1, any idea where to check if it supports the same resistor values for smart dock?
[Galaxy S III Accessories] its.mahmud:
success on diy smart dock! but 4.1.1

hi everyone. just want to give an update that i was succeeded to make mhl and otg work together!

but my galaxy s3 is running on stock rom 4.1.1

here i am adding some picture.

since its working on 4.1.1, iam not updating to 4.1.2 until anyone find out how to use otg and charge the phone together on 4.1.2

thank you
[Galaxy S III Accessories] NHS2008:
This is great!

If its working on 4.1.1, Why won't it work on 4.1.2?

Now you need to contact a manufacturer in Shenzen, and mass produce these and put them on sale! :good:
[Galaxy S III Accessories] TheBlackCat13:
Can you explain exactly what you did? Thanks.
[Galaxy S III Accessories] its.mahmud:
It is working in 4.1.1 but some users are saying charging and otg doesn't work together using 40.2k resistor after they update their galaxy s3 to 4.1.2

here is the video:

http://youtu.be/EFzX6NlKJBU
[Galaxy S III Accessories] its.mahmud:
hi here is what i did.

i failed my 1 attempt what is in the begining of this thread.

then this time i opened a 11 pin to 5 pin adapter. it has a small resistor which is connected ground to sense pin for hdmi out put. i removed that resistor and i connected 5 extra wire in the adapter 1. vcc 2. data+ 3. data - 4. sense 5. ground ( i showed in picture) . then i connected sense and ground with a 40.2k resistor.

then the 4 wire, which i i connected in 11 to 5 pin adapter (vcc, data+,data-, and ground) , goes to a femele usb where you will connect usb devices or usb hub.

and thats it!! hope you can try it too. if if have any other question just ask me :)

[Galaxy S III Accessories] TheBlackCat13:
Thanks, I will give it a shot when I have some time. Do you think there is any chance the same approach would work with the MHL 2 adapter? Having to daisy chain together 3 components (11-5 adapter, MHL adapter, and hub) doesn't seem like the most convenient approach.
[Galaxy S III Accessories] its.mahmud:
i didnt get your question. what did you mean by "MHL 2" ? did you mean the 11 pin mhl adapter? if so ; i would not recommend that because you have to place the 40.2k resistor in between sense pin and ground pin. so i dont want to touch anything inside mhl adapter.

taking out an extension from 11 pin to 5 pin adapter and connect them little more conveniently is possible which i am trying now. but still you need those 3 components to make it work though.

i am not sure if i could answer your question correctly, if u post a diagram of what you are thinking ,that will be easy for me to understand :)
[Galaxy S III Accessories] TheBlackCat13:
That was what I was asking, thanks.

I think I am more concerned with being able to charge the phone and use the USB host at the same time without using a USB hub (which I don't even know if it charge the phone anyway). .
[Galaxy S III Accessories] its.mahmud:
mine is charging the phone aswell. if you follow the diagram i put, it should connect usb host , mhl , and charge the phone at the same time...

you wanted to buy that from me, but if you follow the diagram you can make 1 easily. if you dont want to make and just buy mine; you can PM me

thanks
[Galaxy S III Accessories] ZenInsight:
ok. Will PM you when I get around to it. Thanks!!!
[Galaxy S III Accessories] athlonxp2300:
I made one. bought 11 to 5 pin adapter, otg cable, and mhl adapter from monoprice. had resitors to total 40.2k already.

cut the male end off the otg adapter.

opened the 11-5 adapter. removed the tiny resisor. soldered the positive wire and sense wire.

lifted the other 3 pins to make them easier to solder.

once done it worked on my t-mobile. s3 t999 with 4.1.1
[Galaxy S III Accessories] ZenInsight:
Wow. You made one too? I wonder why this only works with 4.1.1. What happens with the next ROM that breaks it?
[Galaxy S III Accessories] Sandman333:
How accurate does the resistor have to be? I'm trying to get 40.2K with a 1.2K and a 39K. My 1.2K are close enough, but my 39K all seem a little too low or too high.

Is +-1% ok? then 39.8 to 40.6K would be ok.
[Galaxy S III Accessories] its.mahmud:
i used 40.2k 1/4 watt 1% Metal Film Resistors

so +-1 will be ok i guess
[Galaxy S III Accessories] neudof:
I am planning on building one of these for my Galaxy Note 2 (Sprint)

What about adding a USB to RJ45 adapter?
[Galaxy S III Accessories] its.mahmud:

[Galaxy S III Accessories] neudof:
I was wondering if you could wire one of these into the project.

http://pages.ebay.com/link/?nav=item.view&id=150938306559

If the phone would support it would sreaming via usb ethernet be faster than wifi?
[Galaxy S III Accessories] its.mahmud:
Does it work with regular usb otg? If it works with regular otg cable it will work with this project too. And idk if it will be faster than wifi . I have 10 mbps internet connection at home. When I run speed test on my computer I get 10 to 15 mbps there. And if I run speed test on my phone while connected via wifi, I get around 5 to 9 mbps speed. That's pretty much enough for me.

But there is nothing wrong in trying new things! !! So try the RJ45 adapter in a regular usb otg cable and see if the phone support that.

Good luck :)
[Galaxy S III Accessories] neudof:
I have not built one yet and do not have any of the parts to try it out yet. I am going to order everything and see what happens and ill post the results.

If anyone has a usb host and a usb to rj45 can you give it a try and let us kniw the results?
[Galaxy S III Accessories] its.mahmud:

Ok,

I have my 11 to 5 pin adapter and usb host cable and the capacitors are on the way :)

I have never done anything with soldering before sooooo.. Can someone tell me how to take the 11 to 5 pin adapter apart without destroying it?
[Galaxy S III Accessories] its.mahmud:
How I did is ... slide a knife in between the joint part of the adapter. Well which adapter it is? The plastic one or aluminum cover one????
[Galaxy S III Accessories] neudof:
I got the metal one, and was able to get the board out. Now from your pictures i believe I have to disassemble the 2 halves of the board.. any advice on that?
[Galaxy S III Accessories] its.mahmud:
Yes. You have to remove the resistor that is connected between ground pin (pin 5) and seance pin (pin 4) and connect the 40.2k resistor there . To do so I used the soldering iron. I held the soldering iron in each side of the resistor and pushed the resistor slowly with a metal (lol I dnt know what that is called in English. You can use anything for this)

After moving one side of the resistor little bit, I moved the other side. Then again the 1st side. It took little long , but I didn't wanted to make any damage in board. So I did it slowly. Its a job of 30 second if you have a hot gun. I cant afford to buy 1 yet :D so I used my technique. Hope you can do it successfully! Wish you good luck! !

Success! I'm all done. It looks like using a mouse and HDMI causes quite a bit of power draw. So much that it doesn't really charge when using a 1A charger. I might be looking into a higher-powered option soon, or a way of injecting 5V to a powered hub.

Here's all of my pictures (the adapter is resting on the sheet I used for instructions too)

[Galaxy S III Accessories] voyager20021:
Is this possible using the new 11 pin mhl cable? I already bought it and i want to use my USB touch keyboard while connected via mhl. I mean could an 11 pin mhl cable be made OTG capable without using the 11 to 5 pin adaptor? Can i apply the exact same method to the 11 pin micro USB connector from the mhl cable?
[Galaxy S III Accessories] its.mahmud:
yes it should be...

but the problem here is.. you have to take apart your 11 pin mhl adapter, disconnect the resistor between the pin 5 (gorung ) and pin 4 (sence), and then you have to add 40.2k ohm resistor in between those 2 cable. then you will take out 4 extensions for usb . (VCC, DATA+,DATA-, and GROUND)

if you take your mhl adapter apart. can you please take some snap shot of that? i want to see iff all 11 pins are connected there or not and where is the resistor located.

hope you got your answer :)

Another question: when using 11 to 5 pin adaptor, the mhl resistor on the mhl cable (not the 40.2 kohm one on the adaptor) remains there (there is one right?). So if i take it off on my 11 pin mhl cable (without having the adaptor) and replace it with the 40.2 k one, will the phone still know i connected the mhl?
[Galaxy S III Accessories] AlzerDroid:
Hey guys, I would like to thank the OP for such an interesting post, I have some decent enough electronics background although I have not used my skills and knowledge for quite some time now. Im a little rusty but I have great soldering skills etc....

Would I be right in saying that this could be possible by purchasing all the parts seperately to be soldered directly onto a PCB, (Printed Circuit Board) ???

instead of purchasing a 5pin to 11 pin adapter, just buy each socket type and design all the wiring connections from scratch onto a PCB.. I could do this with ease.

Do any of these components have chips on them of any sort, or are they all just little circuits for routing connections with some resistors ?

This would be an easy task for me if there is nothing more than general components i.e. resistors.

Also I have the MHL2 11pin samsung adapter, but from what ive read its not used, thats ok though.

I could source all the parts from my local electronic store.

Ill post my progress here, if thats ok from the original poster.

Yes in 11 to 5 pin tip has a resistor , I took it of and replaced with 40.2k resistor. And if you put 40.2k resistor, thr resistor will active the mhl and otg at same time. So u dnt need another resistor for mhl. :)

after i made the first connector, i was trying to make it little more flexible and easy to use.

and ... i came up with this:)

and then progress of yesterday where all the joints was outside of the usb hubView attachment 1879914View attachment 1879916..... and today, everything packed inside :DView attachment 1879967

i will try to make a video soon :)

to do this i needed 1 cable that contains 8 wires. but couldnt find any round cable that has 8 wires in it. at last i cut my hdmi cable !! :cyclops:

there were about 19 wires in it, so i cut little part of it and joint it bk .

The box will have:

1. HDMI female socket : (for HDMI cable to TV)

3. one wire coming out : (for micro USB to phone)

2. Multiple USB female sockets : (to connect peripherals like mouse and keyboard)

3. a power socket : (to power all components) this will charge phone and power the USB hub

I can design and make my own Printed Circuit Boards, and I can design electronic schematics on my computer..
