  • I am reading many forums since 2 weeks (home cinema-fr.com, www.avforums.com,www.homecinemachoice.com) and reviews to better understand how to choose the right screen for my Panasonic PT900-AE. I am more or less installed in my new apartment, but in order to profit of the biggest room (6.4m * 3.6m), I have to use a wall with either windows or a door in the middle. Time to shop for a screen instead of using the white wall...

    A lot of companies are selling screens, and if You do not take care, You'll end up very quickly with a 200euro screens, which are per see not bad, but really not adapted for home cinema.
    You will find a lot of tutorials and guide on the Internet helping You choosing the right screens. Stewart being the Rolls-Royce brand of screens (but it start at 8000CHF)

    The 3 major parameters are:
    1. Screen Gain : The ability of a screen to direct incident light to an audience. A flat matte white wall has the gain of approximately 1. Screens with a gain less than 1 attenuate incident light; screens with gain more than 1 direct more incident light to the audience but have a narrow viewing angle. For example: an image reflecting off a 10 gain screen appears 10 times brighter than it would if reflected off a matte white wall. Curved screens usually have larger gain than flat screens.
    2. Viewing Angle:Screens do not reflect equally in all directions. Most light is reflected in a conical volume centered around the "line of best viewing". Maximum brightness is perceived if you are within the viewing cone defined by the horizontal and vertical viewing angles.
    3. Your budget: we can not all buy a Stewart Firehawk (anyway it is optimized for DLP not LCD).

    The presence of black band to hide eventual artifacts created by the projector (but it can be solve by software), the transparency of the screens is also important....
    At the end, I was reading user experience of cheap screens which develop waves after a period of time,  mechanical mechanism problems and so on...I was able to retains 3  models:
    At the end, I was reading user experience of cheap screens which develop waves after a period of time,  mechanical mechanism problems and so on...I was able to retains 3  models:

    Da-Lite Model C A mechanical DaLite, Da-Lite Model C "CSR" 16:9  198x353cm - manual
    which should be the best screen quality of all 2 screens below (screen material only).

    The Model C™ with CSR is a manual wall or ceiling mounted screen with Da-Lite's Controlled Screen Return (CSR).
    CSR is a feature offered exclusively by Da-Lite to assist in the quiet controlled return of the screen into the case.
    Exclusiv home has a tensioned system (seems to be the latest development for avoiding waves in the middle of the screen and still having a rolling screen: the best of the 2 world)

    It has also SOMFY motor, IR remote controller and a price tag of 1980CHF or 1300 euro. It uses  a vinyl screen of gain 1.0.

    In fact it is a screen build by Grandview (Grandview Crystal Screen Co of Canada) http://www.grandviewscreen.ca/Products/LargeFlatSeriesTabTension.htm 
    They are originally out of China and they have decided to add a supply warehouse in Canada. Sariaa is having the same model here: http://www.saaria.com/projectiontechnology/tabtensionscreens.htm

    All 3 Brand sell the SAME model, so do not loose time to look at characteristics and choose the one which is cheaper.


    The last option is the DIY (Do It Yourself), and voila a good link if you have a wall big enough:

  • apple-iphone.3gs.repair.diy

    I will show you how to repair a cracked or broken iPhone 3G, iPhone 3GS, iPhone 4, or iPod Touch screen yourself.

    In brief, what you need to know

    • The 3G and 3Gs screens are different! you can not mount an iPhone 4 screen on a 3G(s)
    • There is NO 3rd party or lower quality screens, all 3rd party repair company just LIE.
    • Different kit are available:
      • LCD only for 12€ to repair a broken LCD screen only: the iPhone has an intact glass screen, however the image behind the glass screen is absent, broken or distorted.
      • Glass + digitizer for 22€ This is for an iPhone 3G device with a broken glass screen or malfunctioning touch screen with the image (LCD Screen) behind the screen still intact.
      • Glass + digitizer + LCD + button + speaker mounted for 42€ the most expensive but the easiest to replace
    • Duration: 30, 15 or 2 minutes depending on the kit

    I went for the most expensive Kit on ebay.fr, which allow you to replace the broken screen by removing 2 screws, an connecting 3 cables!

    By the way I would NEVER send any phone to anyone, how do you think all these private pictures land on forums? removing the sim card is not enough, there are tools to fetch data even after the have been removed!

    Glass + digitizer + LCD + button + speaker kit mounted with all required tools to perform the repair

    apple-iphone-screen-repair-kitapple-iphone-screen-repair-kit2

    Step 1

    Remove the 2 small Phillips screws located at the bottom of the iPhone

    apple-iphone-screen-repair-step1

    Step 2

    Using the suction cups, pull up the screen upper part while retaining the body, it will come with no efforts

    Step 3

    Look at the connectors that you will have to pull off using the tool. Apple numbered the black ribbon cables 1, 2, and 3. The ribbon 3 being hidden under the cable that connect to 2. Just pull the cables in that order 2,1 and 3 off,

    Step 4

    Connect the new screen by plugging in that order 3, 1 and 2. Verify proper operations before closing with the 2 Philips screw the case back.

  • Apple IPhone don’t fly well, and here is a picture to prove it:

    broken.apple.iphone.3gs

    I will this week end publish an online “how to exchange your iPhone 3GS LCD screen yourself”

    • The Glass can be found on ebay for 22 euros
    • The whole assembled kit: Glass + LCD + frame + home button + speakers + kit of 7 tools for less than 42 euro! this is the kit I ordered yesterday online.

    iphone.3gs.screen.repair.kit

    By the way, Apple ask a little bit more than 200 CHF for replacing the glass.

  • There are “Still” plenty of reasons to jailbreak that aren't directly related to iPhone-specific hardware.

    • Cydia, an APT frontend for your iPhone, get all applications, most are open source or refused by Apple!
      By the way, Cydia was offering cut&paste, video editing, back grounding, MMS and more years before Apple gives us the OS 3.0. What’s coming in OS 4.0? skins and themes :-)
    • Winterboard, apply themes and skins to get more funny spring board, for example with the little big planet skins, they are really hundreds of them!
      &160;little.big.planet.cydia cydia.theme
    • Live Clock and Weather icons,
    • SBSettings,a customizable HUD with handy settings switches accessed by swiping across the status bar in any app or in the home screen, numerical status displays,
    • Customizable system fonts,
    • Multitasking support, dead simple: press Home 2 second to put app in background, 2 second more to disabled background, I did not see any huge power drain differences by running 2 instant messaging apps: Skype and Nimbuzz 2 hours without interruption. The only real issue that must be confirmed is that the iPhone get really hot in the back. I would suspect that Apple is aware of this problem and did not switch back grounding application for this reason.
    • Full access to the file system, normal users don’t need that, but developers find it fun!
    • Terminal, SSH (openSSH yes), VNC and VIM, I can now remotely connect to my host with my RSA keys but more on that later..

    How to Jailbreak your iPhone/iPod 3GS

    I MAKE NO SUPPORT, USE AT YOU OWN RISK

    I just want to share here how simple and how easy it was for ME, it doesnt mean it will work for YOU. Search in Google for a solution in case of disaster (iPhone wont boot up), it seems a backup/restore may save you time and eager.

    Jailbreak with Purplera1n http://purplera1n.com&160;

    Run the exe while having your iPhone connected through USB, click on the button “make it ra1n”

    The iPhone will reboot and a new icon “Freeze” will appear. Click on it to install Cydia [WikiPedia]. The operation take less than 1 minute

    NOTE:

    • You can also afterward install cracked Applications by Drag & Drop into iTunes or by double clicking them and Sync with your iPhone/iPod Touch !!!
    • I recommend you to install “Pandora Box”, a free app that run on any non jail broken iPhone and let you review every day or week all paid applications that get a price drop (paid to free, paid drop in prices ). There is enough (crap) to download for free before paying of even hacking the iPhone.

    I will list below the Best review of  projector screens I've found, beside this it is really depressive to see Google only being able to return all these online shops with nothing interesting instead of good reviews articles like these:
    1. White, Grey, or Silver - A Review Welcome to my third screen review. This review will demonstrate three professionally manufactured materials that are White, Grey, and Silver. I hope to demonstrate the differences of what these different screen colorations can offer and how you may benefit.
    2. A Screen Showcase & DIY Review Welcome to my second screen review. This review will include lower gain screen materials, what they do, and what they are made of. I see this as a benefit to people because screen surfaces and materials remain a mystery to most. It will include some DIY materials but must be somewhat limited as there are literally thousands of materials to bounce light off of. So, of course, they cannot all be covered here. Finally, at the end, there will be a fun little shootout between some DIY materials and the infamous Stewart Firehawk. 
    3. The High-Gain/Exotic Screen Review  After critically looking at these screens for over 5 days and taking over 200 pictures I must say this was one hard review. There are so many variables, they cannot all be covered here. In the end, it is important to try to achieve the greatest benefit for the environment or viewing you want to achieve. This review will focus on 5 high power screens surfaces and will include 3 lower power for reference only.
    4. to be continued...
