Not really.

Your schematic shows bypassing the raspberry pi protection circuits. Although this is fine if you know 100% that you have a decent power supply. However, I don't consider this ideal.

My board does away with the microUSB port used to power the Raspberry Pi. Instead it has its own standard DC 5V power in (see picture) which has its own protection circuit equal to that of the Raspberry Pi. It then splits the power supply to the hub and Pi, dedicating constant 5V supply to the Pi through the GPIO. This means when you plug in your USB powered HDD into the PiPUB, the sudden current draw does not effect in any way the power supply of your Pi and your Pi is protected from power surges.
[Raspberry Pi General] Jraider44:
Pretty neat stuff! I need this kind of setup!
[Raspberry Pi General] Dave.6:
I am the co developer of the PiPUB and have a few more technical and operational details to add.

The hub controller is a Multiple Transaction Translator type meaning all 4 ports run at their maximum speed regardless of the generation of USB device that is connected. Some hubs are slowed down when earlier generation devices are connected.

The PiPUB plugs into one of the existing USB ports by a small, near flush PCB connector. For the keener DIY’er you can solder the USB data lines to the back of the Pi’s USB connector.

All upstream and downstream USB ports are protected against ESD by high speed, low capacitance TVS diodes.

5V power is inputted via a standard 5.5x2.1mm DC connecter through a 3A poly fuse and large TVS for over-current and voltage protection. Power to the Pi is then split off through a 1.1A poly fuse to the GPIO pins, similar to the existing power distribution on the Pi. We have loaded up all USB ports to 500mA and had the Pi running with negligible voltage drop.

You can use either the on board IR receiver or plug in the IR extension. They both work at 38Khz which is fairly common amongst remotes. These pass IR from your remote to the Pi via GPIO 18 and also to the microcontroller to control the power to the hub and Pi. You can map your particular remote to control XBMC.

There is a power button and LED that sits to the left of the audio jack above the Pi’s status LED’s.

If the Pi is OFF, pushing the power button or the learned IR remote button turns the power ON. If power is ON and the power script is installed or the XBMC addon we have created is installed, our board will initiate a safe shutdown. If neither is installed power will be switched off straight away. GPIO 23 and 24 are used for this.

On board is an open collector transistor that allows you to switch loads up to 250mA from GPIO 25. The intent of this is to allow people to control their own peripheral like a fan if desired.

It fits into the Black Multicomp and ModMyPi Cases without modification. It is then up to you to drill and cut the holes you want. We recommend the Black Multicomp case as it is an easy plastic to work with, it is the cheapest and certainly looks the part! In the future we hope to design a 3D printable case and a laser cut acrylic case similar to the Adafruit version for people to make.

If you have any suggestions on how we could improve the design and function it would be much appreciated.
[Raspberry Pi General] adamcooks:
Great little board, where do I get one?
[Raspberry Pi General] Dave.6:
Thanks! We will be running a little Kickstarter campaign in the next week or two. Will let you know.
[Raspberry Pi General] phoenix0_4:
Great board! I was looking for a solution to shutdown the Raspberry Pi with a remote control.

Will this board work with the new Raspberry Pi B+? (Just ordered one to get rid of my hub...)

I've got 2 suggestions:

1. add a radio control-module (receiver and sender), so you will not only be able to shutdown the Raspberry Pi but also devices like an external HDD or the TV pluged in a radio controlled power outlets.

(background: I'm using my RPi as server with an external HDD and a printer as well as a wifi-router and when i'm leaving home, I don't use it, so I'm looking for a convenient way to shutdown all devices.)

2. offer a case suited for the Rpi+PiPUB (perhaps as stretchgoal in your kickstarter-campaign?)
[Raspberry Pi General] Dave.6:
Unfortunately it won't work with the B+ as the power button sits where the new set of USB ports are. We may look at producing a B+ version if our Kickstarter is a success (starting in the next 24hrs).

1. If the other devices you are looking at controlling have IR then the PiPub has AUX pads which you could solder 2-3 IR LED's to in series. It is connected to GPIO25 with a transistor so the LED's can be powered correctly. Using LIRC and a script I can see no reason why you couldn't get it to shutdown/power-up your other devices when the learnt IR button for the PiPub has been received. I haven't tried this but it seems more than plausible.

But it sounds like you are using RF controlled power outlets which I'm unsure how you could interface.

2. Like you suggest we would love to offer a case as a stretch goal. Most likely just a laser cut acrylic or 3D printable design. However it would be awesome if we could get Multicomp to modify their design to suit the PiPub!
[Raspberry Pi General] Josh.5:
Kickstarter up and running...

Hi all,

Kickstarter campaign is up.

https://www.kickstarter.com/projects/22555674/pipub-powered-usb-hub-and-power-control-for-raspbe?ref=nav_search

Please spread the word and help us make this a reality.
[Raspberry Pi General] phoenix0_4:
Ah, great! Perhaps, shutdown the RPi via IR is enough. I'll see ;)

I got some new questions...

1. As I understand, the PiPuB has an external power supply. Does this power supply power the Raspberry Pi as well, or does the RPi "still" need its own power supply? (could save one power outlet)

2. Is this IR expansion cable anything special, which can only obtained by you? Would be nice to buy it afterwards if neccessary.
[Raspberry Pi General] Josh.5:
Yup. One of best things about the PiPub is that it removes the need for heaps of cables. The single 5V 3A power supply poweres the USB hub and the Raspberry Pi.

The IR extension is nothing special. You can find these on the internet or even a local electronics store. We tested a few and found some to be less ideal than others in terms of practicality. The one we're offering is what we deemed to be the best option but you may very well find something better...
[Raspberry Pi General] phoenix0_4:
Thanks!

One last question comes to my mind:

How can I use an IR remote with XBMC? In your video, you showed how to program one button of the remote. But what about the rest? I.e. the Flirc USB stick comes with special software to provide this functionality.
[Raspberry Pi General] Dave.6:
XBMC can be configured to receive IR commands through the GPIO port. The PiPub has an on board IR receiver that is connected to GPIO 18 and also an optional external IR receiver that can be connected. You have to run through a bit of configuration to learn your remote and assign the buttons to a function. Some good info about it here.

[Raspberry Pi General] phoenix0_4:
ah, I see. Thanks again. I also found some how-tos in german. :)

So, I backed your project by pledging for a PiPub + power supply. Would be a nice "toy". ;)

BTW, I found a similar kickstarter-project (but without IR or a switch). It's called "Raspiado". (because I'm new in this forum, I can't post a link, sorry.)
[Raspberry Pi General] Josh.5:
Thanks for the support.

Yea, unfortunately the Raspiado beat us to it with the KickStarter. I think the Raspiado is nice, but does not solve many of the Pi's issues. I don't understand the purpose of thes long custom USB cables if you're trying to reduce clutter.

What we wanted to focus on is the main issues faced by users of the Raspberry Pi in MediaCentre applications. This being said, the PiPub is still very useful in other applications. Just the power switch alone is massive capibility addition. See: https://www.modmypi.com/pi-supply. This sells for $23USD. Our PiPub is $33USD and does this while still fitting inside your Raspberry Pi case!

Thanks again for your support. :highfive:

Please repost this elsewhere and help us spread the word.
[Raspberry Pi General] phoenix0_4:
I just made the announcement in a german Raspberry Pi-forum and in the OpenELEC-forum. Perhaps it will help...
[Raspberry Pi General] Josh.5:
Thanks for that.
[Raspberry Pi General] phoenix0_4:
you're welcome.

Do you know any htpc-forum, which could be another good address?
[Raspberry Pi General] MasterDev:
Alternative

Now that this project did not happen, there is an alternative add-on board available, called RemotePi Board (msldigital.com), it has similar functionality, the IR receiver and power controller but no additional USB ports. Because they have a version for the Raspberry B+ which has 4 USB port this may be a non-issue.
[AT&T Samsung Galaxy S 4 General] crazzysandman:
Has anyone tried this yet? Found it on Gizmodo. Downloaded and installed it was a simple one click and root seems fine. This was tested in my s4 on latest 4.4 anyone have any other input on this?
[AT&T Samsung Galaxy S 4 General] NighthawkXL:
Yes... it works with every model of the S4, except the T-Mobile variant.

Nearly on every Android device (with exceptions of course) with a kernel build prior to June 3rd, 2014 for that matter.

It's not made by some no name amateur... it's made by Geohot, whom is known for his previous work on the iPhone Jailbreak scene, and the PS3 jailbreak scene.
[AT&T Samsung Galaxy S 4 General] crazzysandman:
Yeah I did read the article on him. Pretty crazy what he did with a ps3. Well so far phone had been rock solid. Greenify is running and saving my battery once again
[AT&T Samsung Galaxy S 4 General] Peñaran561:
Not every model, doesn't not work with the T-Mobile variant.

[8525, TyTN, MDA Vario II, JasJam General] dandare123:
Appearantly, SoftBank Japan disabled the wireless modem function on the X01HT that ships now in Japan for the last 3 days. The 'Wireless Modem' app is missing on the Start Menu.

I've been trying to connect via Bluetooth, but without the required steps with 'Wireless Modem' I had no success. Running the same sim in a SoftBank cell phone with Bluetooth enabled successfully allows me to connect my Laptop via the phone. This function missing in the X01HT is really annoying.

Anybody have any idea how I could get the 'Wireless modem' app installed/running without flashing the ROM?
[8525, TyTN, MDA Vario II, JasJam General] elfwine:
I've been looking for this app too... what's the progress, did you find this app?.
[8525, TyTN, MDA Vario II, JasJam General] Zgembo:
Mee too... SoftBank's ROM really sucks. I'll check this soon, This app may be in other provider's extendend ROMs or somewhere...

[LG Optimus 4X HD] Senchay:
Hello together,

i used search and the suggested topics but i cannot see the same problem as i have.

Recently i rooted my 4x hd with success (i used Kingo Android Root, as i found here in the forums) because i want to install Cyanogen Mod, installed Rom Manager and downloaded the CWM Recovery (not the touch one, the lates it can find, 6.# or something was it) through that. Then it got installed and finished without error. Of course i gave Super SU right to Rom Manager. Its shown as installed in Rom Manager too.

So the problem starts when i want to boot into the CWM, no matter wich way (through volume down + power or in Rom Manager with the "boot into CWM" option. When i try this all i get is 2 lines in minimal red font on a black screen. I forgot was was written there but it was really hard to come out of that. Finally the phone booted normally. I tried it 2 more times, with same results. I also re-isntalled the CWM over the Rom Manager, it just stays like this.

Whats wrong?
[LG Optimus 4X HD] Omario-242:
You did unlock your bootloader, didn't you?

If not your bootloader gets screwed and you have to reflash kdz (search for tutorials).

You can't boot into cwm because if the BL is locked, you don't have the permission to change recovery/rom

(not actually permissions I think but easier to describe it that way).

So the recovery is now corrupt and there's no way beside the one I already mentioned

(you can try to unlock your BL but I don't know if it's possible in your state.
[LG Optimus 4X HD] Senchay:
Thanks for the fast answer. Makes sense,

In the tutotial i followed that time was unlocking bootloader not mentioned, i didnt do this by hand, no. Honestly i thought this will be done by the root tool.

Edit: found your answer to that, sorry.

Anyway, so can i still do this now or did the bootloader got already srewed on first try when accessing CWM?
[LG Optimus 4X HD] Omario-242:
Sorry I was a bit incorrect. The bootloader should be fine (at least when you reflash kdz as the stock recovery will get flashed as well). After that you can unlock your boot loader and flash any custom ROM.
[LG Optimus 4X HD] Saenchai:
Thanks.

I did it in another way, i think it solved it too (probably its doing the same...). I downloaded the LG Support Tool from website and used the Option "Repair Upgrade-Errors/ Behebe die Update-Fehler" without to really know what happens (hehe) and it seems to reflashed some important things, without to wipe any data though. Anyway, the root is gone now but i can go into the LG Recovery at least.

What bugs me a bit is the question if this LG recovery is the standard or if theres still a problem? Because the "recovery" i mean is only a picture with an LG Logo and something like "LG Recovery Mode -- Service Center. After put out and re-insert battery use the power button to keep using the phone."

Is this the real recovery? I had a lot of phones but never saw a recovery like this...

I have noticed that sometimes the vibrate function does not work on my Z2 Tablet. Sometimes it doesn't work at all from the moment I switch the device on, and other times it works to begin with but then stops after a while.

Is this a known issue or has anyone else experienced it?

You can't use greenify (xposed settings) with ART.

Xposed isn't compatible with ART (Unless it's changed since i last looked?)

Some good tips in there though!

Can someone please explain whats xposed framework is? and what does it do? Thanks
[Galaxy S 5 General] Chaitanyapatel8880:
Xposed Framework is an application which is required to run several other apps. It allows third party applications to work on OS without needs to flash the ZIP files via CWM/TWRP or any kind of recovery, which inturn gives more controls and less hassle for the people like me who love to keep modifying the system. further more explanation can be found here in the link.

i tick in developers settings use ART , my phone reboots normaly ,but nothing happens :( why ?:(
[Galaxy S 5 General] Chaitanyapatel8880:
by activating ART, your phone will process the files and applications more faster than dalvik. for example: it will open the game or any other application more faster than dalvik or it will be more smoother to operate.

Here is a video for example.

https://www.youtube.com/watch?v=U5oliXcOqxg
[Galaxy S 5 General] dandroid13:
I'm sorry, but what's the point in turning off NFC? It only activates when you use it...
[Galaxy S 5 General] Chaitanyapatel8880:
Simple thing if we are not using it than batter to disable it. it is just one tap away... If someone doesnt want to disable than it is up to them. It just drains approx 0.5% and that is also only while the screen is ON. it is completely off when the screen is off...
[Galaxy S 5 General] ManDone.vRs:
yea bro´ , i know what is do ART , but in my SGS5 it´s doesn´t work ... , after i tick ART in developers settings , after the next reebot , should be ART selected , another thing , after i tick ART option , my phone boots in 55 seconds ( the time when i tick ART mode ---->>> my lockscreen )
[Galaxy S 5 General] Chaitanyapatel8880:
Sorry for that misunderstanding. There should be something wrong with rom or kernel than I think.
[Galaxy S 5 General] dandroid13:
Sorry for being a d!ck but build.prop tweaks aren't efficient anymore, also, keeping wifi scanning turned on can actually save battery. :)

[Galaxy S 5 General] ManDone.vRs:
Yes ! i am using xposed framework and modules
[Galaxy S 5 General] dandroid13:
So, you can't use ART with Xposed. Uninstall it or live with Dalvik.
[Galaxy S 5 General] Chaitanyapatel8880:

[Galaxy S 5 General] ManDone.vRs:

[Galaxy S 5 General] dashrink:
The developer of xposed has stated that it wont support art until it becomes the default runtime. Atm its still dalvik.

[Galaxy S 5 General] ManDone.vRs:

[Galaxy S 5 General] Chaitanyapatel8880:
This is just a new technology so definitely it is not going to give same result on all devices... Lets get best out of it. it worked great for me but had to switch back to dalvik due to xposed.
