fixed : 5V 4A car adapter for Samsung Optical SmartHub SE-208BW

Posted on by

Question :

I have a Samsung Optical SmartHub SE-208BW (all-in-one : WiFi-DVD player, media streamer,  WiFi-router and DVD+R burner), and since it is capable of streaming DVDs and HardDisk content to my iPhone/iPad using the Samsung SmartHub iOS-app, I thought it would be a great idea to use it in my car also.

However, if I power it using the USB-cable that comes with the SmartHub, it is limited to not act as a WiFi-device. So… I need a ‘dedicated’ car-adapter for it…

But… the power needed is 5V and 4A minimum… that’s a really rare combination… and Samsung does not sell any car adapters for the SmartHub, neither do they have any recommendation on a good solution…

What options do I have ?

Answer :

The Samsung Optical SmartHub SE-208BW is a rather unique piece of equipment. Combined with an iPhone/iPad and the SmartHub-app, it is a really versatile solution …if you keep in mind that it still has some little flaws…

If you ask Samsung how to power the Samsung Optical SmartHub SE-208BW in your car, they will recommend using a cigarette-lighter-to-220V-transformer…

…that’s a stupid ‘solution’, since transforming from 12V to 220V and back to 5V is both a complete waste of energy resources and it will drain your car battery…

So… after elaborate search and testing, I’ve found a ‘real’ car adapter solution for the SmartHub ; you should create a car-adapter yourself consisting of these three parts :

1- a USB to 5V DC Barrel H power cable like this one :

USB to 5V DC Barrel H power cable

2- a USB Y-connection cable (2x USB-male to 1x USB-female) like this one :

USB Y-connection able

3- a 5V 4.2A dual-USB car adapter ; at this moment, there is only one product like this that actually works :

If you join these 3 parts together into, you’ll have exactly the car adapter you need for the Samsung Optical SmartHub SE-208BW.

info : streaming just one DVD to 2 iPads at the same time

Question :

I would like to watch a DVD on my iPad (without having to convert the DVD), but… as I have 2 children, I would even prefer to enable them to both have their own iPad/iPhone and watch the same DVD.

Is there any solution to do so ?

Answer :

This can be done by steaming a DVD to your iPhone/iPad. There are several options to do so, but one of the most interesting ones I’ve found requires a WiFi DVD player.

The smallest WiFi DVD player I’ve found is the Samsung Optical SmartHub SE-208BW :

Samsung Optical SmartHub SE-208BW

(The SE-208BW has several intended uses, it can be a WiFi-router, or a DVD-burner for netbooks, or a wireless DVD streamer, media streamer or 1-click back-up for iOS or Android devices, for instance…)

To use it with an iOS (or Android) device like an iPhone or iPad, you will also need the FREE SmartHub app :

https://itunes.apple.com/en/app/mobile-smarthub/id483986474?mt=8

– plug the SE-208BW into the wall power

– open the DVD-tray by pressing the small button on the front

– put in a movie-DVD

– close the DVD-tray

– on your iPhone/iPad, go to Settings, then in Wi-Fi, find the SE-208BW’s WiFi-network and connect to it (note : the name and password of the WiFi-network are indicated on the bottom of the SE-208BW, the name of the WiFi-network will be something like “208BWxxxx”)

– open the SmartHub-app (*)

– if you get a “Turn on WiFi first” connection error (or if the two rings in the WiFi-icon top-right are not chained), just exit the app, go to Settings and reconnect to the SmartHub’s WiFi-network

– then click on the green rectangle marked “DVD Player”

– now the “DVD Server List” opens ; the screen will be mainly black at first and then show the “Smart Hub Server”

– then open the SmartHub-app on your second iPhone/iPad also, click the green “DVD Player” rectangle, and wait for the “Smart Hub Server” to appear in the “DVD Server List”

– then click “OK” on both the first and the second iPhone/iPad, and the DVD will start on both iDevices

…that’s it : you are now watching the DVD movie on both iPhones/iPads

note : even though you are watching one-and-the-same DVD on two ‘screens’ at the same time, they are NOT synchronous, so it’s best these things in mind :

– use headphones on both iPhones/iPads

– you have to pause the movie on each ‘screen’ (iPhone/iPad) separately

– using the FastForward and/or Reverse options during playback of a movie on both ‘screens’ will usually cause interference (like frame-scipping, unexpected halts or viewing quality decrease) on the other ‘screen’

(*) if you need to do any additional set-up on the SE-208BW you can do so from within the iOS-app

NOTE :

streaming only one DVD to 2 iPhones/iPads at the same time using the Samsung SmartHub tends to work okay, but chances you’ll see ‘halts to cache’ are rather high… so do not expect as flawless movie-viewing as you can get with a ‘regular’ (non-streaming, but wired) DVD-player

FYI :

I have found only one car adapter for the Optical SmartHub. More info can be found here :

fixed : auto-connect to other WiFi-network

Question :

At one of the locations I often visit there are various WiFi-networks I can use. But whenever I am in the neighborhood my iPhone auto-connects to the network with the worst connection for some reason. Since I need a reliable connection, I always manually switch to the best network, but when I leave and return, my iPhone keeps auto-connecting to the worst WiFi-network.

How can I set my iPhone to auto-connect to the best network ?

Answer :

You can’t set an order in the WiFi-networks your iPhone/iPad remembers. But you can easily fix your main problem by deleting the worst WiFi-network from your iPhone/iPad’s memory like this :

– on your iPhone, go to the Settings-app (the sprocket/gear-icon)

– on the Settings-page, choose “Wi-Fi”

– on the Wi-Fi-page, see if the ‘worst WiFi-network’ is in the list – if not, move/walk over to a location where the ‘worst WiFi-network’ does appear in the list

– if the ‘worst WiFi-network’ is in the list, click on the ‘blue dot with a white arrow’ that is behind it on the same line

– on the page that opens, click on the “Forget this Network” button that is on the top of the page

…that’s it !

fixed : stop FaceTime over mobile network

Question :

Today I got a call on my iPhone when I was in my car, but when I answered, it turned out to be a FaceTime-call. I do not want to answer video-calls in my car because I think it is too distracting and dangerous during driving and because my GSM/3G-provider will charge outrageous rates for mobile data.

Is there any way to prevent my iPhone from connecting through FaceTime when I am out of WiFi reach ?

Answer :

Yes.

…and it’s quite simple to configure :

– on your iPhone go to the Settings-app (sprocket/gear icon)

– select FaceTime (in the chapter that starts with iCloud, in between Messages and Maps)

– in the FaceTime settings page that opens, scroll down to the very bottom

– there, set Use Cellular Data to OFF

…that’s it

enjoy !

fixed : Time Machine backup error “sparsebundle in use”

Posted on by

Question :

When Time Machine tried to backup today, it returned an error saying “Time Machine Error. The Backup disk image ….sparsebundle is already in use”. As I am the only one using this backup, I hoped that just trying to do the Time Machine backup manually would help… but it didn’t… it returned the same error…

Restarting my Mac didn’t help either…

How can I fix this ?

Answer :

The “sparsebundle already in use”-error occurs if something went wrong during the last backup (which could be because your Mac froze during the Time Machine backup). In that case your Mac did not properly disconnect from the Time Machine backup, so you will have to do so manually.

Fixing this is rather simple :

If you still have ‘the old’ Airport Utility 5.6 on your Mac (more info on this can be found here : https://macmanus.nl/2012/02/02/airport-utility-6-lost-the-option-to-configure-connected-printers/ ), you should do this :

–  open Airport Utility 5.6 (which is in the Utilities folder inside your Applications folder)

– select your Time Machine backup drive on the left (e.g. your Time Capsule)

– click on the “Manual” button

– then select the “Disks” icon

– and click on the “Disconnect All Users…” button

– then exit AirPort Utility 5.6 and run Time Machine normally

– …and do not forget to check in the time Machine Preferences if Time Machine is switched ‘ON’

if you do not have AirPort Utility 5.6 (since your Mac has OSX 10.8 “Mountain Lion” in stalled, which only has the stripped-down AirPort Utility 6 without the “Disconnect All Users”-option), you could either download and install AirPort Utility version 5.6 (directly from Apple : http://support.apple.com/kb/DL1482 ), or you should try this :

– shut down your Time Capsule a.k.a. “pull the power plug” (or other Time Machine backup drive)… and leave it disconnected for about 5 minutes or so

– restart your Mac

– power up your Time Capsule a.k.a. “plug the power cord back in” (or if you have some other sort of Time Machine backup drive, turn it back on)

– go to the Time Machine icon in the Finder’s top menu bar and click “Back Up Now”

– …and do not forget to check in the time Machine Preferences if Time Machine is switched ‘ON’

That’s it !

fixed : 10.7.5 refusing to see the Atheros AR9280

I must admit the title might be a little misleading, since I have not had anyone claiming problems like the “WiFi: no hardware installed”-error with the Atheros AR9280 AirPort-card and MacOSX 10.7.5 yet, but still…

…that is probably due to the fact that the MacOSX 10.7.5 updater doesn’t overwrite the IO80211Family.kext system extension. So if you are upgrading from an earlier version of MacOSX 10.7 “Lion” which you had already ‘patched’ for use with the Atheros AR9280, you won’t get any (new) issues…

Anyway…

If you do get the “WiFi: no hardware installed”-error after upgrading to MacOSX 10.7.5 (e.g. from MacOSX 10.6 “Snow Leopard” or earlier), you can just do the same ‘patch’ of reinstalling the old IO80211Family.kext system extension. Instructions for doing so can be found here :
