I don't understand about electronics that much.. my field is medicine
My question is, can we build it?
Cheers.

Unfortunately that is not all we need. As far as I know, there is some additional circuitry in that little box.

That's definitely the case; I've read that MHL devices switch between MHL & USB modes based on the resistance across two pins on the 5-pin microUSB connector. So you'd need to duplicate that, and there's also some circuitry to convert the MHL video out signals to HDMI. SiliconImage makes a family of such chips.
Also, there's probably some magic involved in integrating the +5V from the microUSB charger input into the MHL connector, so as to keep the SGS2 charged while it's playing video. You'd at least want some current/voltage limiting circuitry to protect your expensive TV & phone from being zapped by a bad charger.

Here is a far more detailed description of the mhl adapter: http://www.wilder-tech.com/pdfs/Tektronix_MHL-TPA_User_Manual_Rev-A.pdf
:good:

MHL Cable is an active cable, meaning that there is an active circuit (Controller) within the cable, there are ways to home manufacture it, assuming that you have the required equipment and knowledge . but it just doesn't any sense. Unless you are doing it as a study case.

Charge Raphael from 12V car battery?

Anyone seen a cable converter to allow me to charge the Raphael from a 12V car battery when there is no access to a cigarette lighter socket?
Thus, aligator clips (or similiar) that connect to the +/- terminals of a 12V battery, and then the other end has the mini-usb connector that plugs into the Raphael. Seemingly in the middle between the two would be a 12V to 5V step down.
Anyone seen such a cable? I guess I could get a standard cigarette lighter style and break it apart and solder on some aligator clips?
um.. that would most probably result in a mini explosion that will cause your fuze to go up in flames and clouds of dark ozone destroying smoke... and maybe for you to lose a hand in the process.... I highly suggest you find a different alternative...
just my 2 cents..
go to walmart and find something like this. plugging directly to a battery is a very bad idea.

Get a cigarette lighter extension and cut off the male end. Put gator clips on the wires to the female end. Works awesome.
Be careful to get hot and ground correct.
Try one of these adapters "Lighter Socket Alligator Clips". Obviously you'll still need a HTC (or suitable) cigarette lighter charger. Only about USD6.00.
Cheers!

[Q] car charger

hi, just got x10 but i have for it 2 car chargers and both not working, does anyone know do i have to change some settings in phone? cheers for any help
Is your car lighter ok?
i have a similar problem,.... i have a USB cigarette lighter adapter that i used on my previews phone,....
it doesnt work when i try to charge my X10,... (im using the original SE data cable,....)
A lot of the standard car chargers won't work for X10 for some reason.. they must be wired slightly differently.. you need to order one which is X10 compatible. I had a Jabra adapter which I tried with my USB cable and it didn't work..
Also - This thread should be in the Accessories section. MOD - can you please move?
Thanks.
Just a note of advice here... Make sure you're using a USB POWER cable instead of a DATA cable. If you're using a cable other than the one supplied with the X10, it may not work for charging.
FYI: The Motorola microUSB chargers work perfectly fine with the X10
There is a fix for your problem in this forum. Take yourself a digital meter or something like this and check if there is resistance.
If they are not connected (I bet they aren't) just solder the two data pins in your charger together (middle pins). Then it should
work!

ya, my blackberry car charger works perfectly with the x10
I bought 2 chargers the other day. They both worked. Only paid $3.50 per charger too and got free shipping because I have amazon prime:

I'm using the Nokia charger and it's working great so far.

[Q] Chargers compatibility

I have bought a usb charger on ebay, but it doesnt work with X10, any solution? Why?
The charger:

1. This belongs in the Accessories section
2. The answer to your question: because the SE charger has the pin 2 and 3 (the data pins) of the USB pinout shorted. Normal chargers does not have these shorted. Don't ask me why, it just seems stupid and proprietary to me.
Can you explain better? I cant use others chargers? I cant use others microusb cables?

You can use a charger from a blackberry 9700, for sure and the 9000 I think. The bit about pin 2 and 3 shorted is true. I have a cigarette usb charger that came with my bluetooth gps and it would not work with my Iphone/ipod nor with my X10, I shorted or joined pin 2 and 3 ( the middle 2 pins ) and now it works just fine. That unit you bought is it not for the iphone? So you can open up the charger and short out pins 2 and 3 or modify the cable. I suggest you label the cable for charge only as I think it will not allow data to flow.

Because it's white.

Tab 10.1 w/HDMI Connection

I swear I saw a thread about this but I couldn't find it. So I figured I'd share this with everyone. It so simple its stupid!!! Thanks Samsung for making a completely useless multimedia dock and forcing me to make one myself.
Here's a video on how to do it

....figured I would link these together for the other helpful info over there.
Do you or can anyone tell me if the HDMI and the usb are operable at the same time? I have an in-car custom set up I'm planning and I think I have it but I need to know if they'll work together. I only need the 30pin to usb cord for charging. The rest of it will run off the HDMI. I could post up a schematic of what I'm trying to do if anyone is interested in helping with the design of the project. Thanks!
I would also like to know if you can use hdmi and usb at the same time. for example you can use an xbox usb pad and hdmi to a tv on the xoom and charge at the same time, could this be done on the 10.1?
Is it mhl. if so it switches between depending on which is plugged in. so its either hdmi or usb not both. dumb i know. it can charge at the same time though.

[Q] MHL not working. Any ideas please?

Hi all,
My Note 3 is using the latest official UK firmware (although it's rooted) and the HDMI MHL feature refuses to work, and I suspect it may be the dock.
I bought this

Basically, I plug it all in, it says HDMI connected. I then switch to the HDMI source on my monitor, the phone then quickly says HDMI disconnected, then HDMI connected. However the monitor stays black/in HDMI saving mode.
I was sent a second one from the shop because the first one appeared faulty and the second doesn't work either. I've made a quick vid of my experiences...any ideas?
Shameless bump!
I don't know much about MHL, so I can't give you specifics, but I know there are 2 different pin configurations. The MHL cable I have came with a little tiny adapter for that, and the only way it works is if I plug the adapter into my phone, plug the MHL into the adapter, and plug power into the MHL. Maybe it's something similar?
Mine isn't Samsung, but this is basically what my cable looks like, with the adapter thing....
Cheers, yea I did wonder about that. It's one of these mass produced Chinese items so maybe the sellers have got it wrong and it's not Note 3 compatible at all! I've messaged them and I'll see what they say about it all. Cheers
