Connect a MacBook Air to an Optoma PK 101 pico projector

Optoma PK101

Optoma PK101

Back in mid-December of 2008, I reviewed two new micro, or pico, projectors: The Dell M109S and the Optoma PK 101. The Dell model was designed to connect to a wide range of devices with its multi-cable adapter, but the Optoma PK 101 (the sexier of the two devices) was designed, primarily, to connect to devices with composite video connections, though it came bundled with an adapter for iPods and iPhones.

My Optoma PK 101 review mentioned that “The Optoma PK101 isn’t configured for connecting to a laptop or computer. unless the computer itself as a special video output.”

A few days ago, Mark Canavan, a Skylarking reader, wrote in asking, “How can I connect the Optoma PK101 to a MacBook Air laptop?”

Here’s your answer, Mark. I’ve also added this information to the end of my original review of the Optoma PK 101 projector.

Apple Micro-DVI to Video Adapter

The Optoma PK 101 is designed to connect to devices that have composite video connections. The MacBook Air has a mini display port that can be used as follows. If you’re averse to tech-talk, just ignore the stuff in the parentheses:

This is according to the MacBook Air’s Technical Specifications web page.

According to a MacBook Air Developer Note from Jan. 18, 2008:

The MacBook Air ships with a micro-DVI to DVI adapter and a micro-DVI to VGA adapter. A micro-DVI to video adapter, which provides composite and S-video support, is sold separately.

The Apple Micro-DVI to Video Adapter (shown above right) is available from the Apple Store in the US and Canada for $19. Apple says, “The Micro-DVI to Video Adapter was designed specifically to fit the slim profile of MacBook Air. The adapter connects to the Micro-DVI port on your MacBook Air and provides both S-video and Composite video connectors so that you can view content from your computer on such devices as TVs, VCRs, or overhead projectors with S-Video or RCA (Composite) connectors.”

Thanks for your question, Mark!

More Info for Connecting an iPod to a home stereo


Back on Sept. 16, 2008, I wrote an article regarding connecting your PC or iPod to a home stereo. A reader, LD, asked about the pros and cons of using a stereo y-connector with the iPod’s headphone jack, which I offered as a relatively low cost solution in my earlier post, versus connecting with a y-connector or kit with Apple’s Universal Dock. You can read his full comments and questions with the original post here.

Here’s my take on the headphone jack versus the universal dock approach:

Apple Universal Dock - Apple Store (U.S.)

Docking Port
I’ll assume the docking port in question is the
Apple Universal Dock from the Apple Store (U.S.)
($49). One advantage is it looks cleaner/neater sitting next to your stereo instead of a loose headphone cable, and it comes with a remote control. If you add a USB power adapter ($29) you could also charge the iPod, but the same holds true without the docking port. If you choose to use the universal dock, your standard 1/8″ stereo y-connector ($7.49) can be used.

Cable and Monster Cable

Belkin Y Adapter Cable - Apple Store (U.S.)

I find the headphone cable and jack suitable, and I consider myself to be something of an audiophile when it comes to stereo equipment, but care must be exercised with the volume control. The rule of thumb with stereo equipment is to always have the volume turned down before turning on any equipment. Taking care to do so has always worked fine for me.

Don’t get me wrong, I love Belkin and Monster Cable, but I’ll pass on them if I’m trying to hold onto my cash that day or week. Currently, I use an ordinary stereo y-connector from Radio Shack, and I have had no problems with it. I play my iPod on the stereo a few times a month, and just leave the cable in plain view.  No one else in the household has complained yet, and most of them are much neater and more organized than I.

To clarify, the standard stereo y-connector will connect to the universal dock, but get the Monster Cable if its in your budget. Their cable is of a higher gauge, and does make a audible difference if you have an ear for it.

Feedback and Amplification
It’s true that the iPod output level with just the headphone jack is affected by the iPod’s own volume control. You should always start with the volume on the stereo and iPod turned down. Then turn up the stereo volume to a level you usually find suitable — you won’t hear anything until you turn up the iPod’s volume — and then set the iPod to play and turn up it’s volume control. Resist the urge to make it “extra loud” by turning it up too high.

Though I don’t have a docking port now, it has been my experience that any device that utilizes the iPod’s connector, instead of the jack, disables the volume control of the iPod wheel. Using the iPod wheel will have no affect on volume.

Another note: Care should be taken when the stereo is on, but an iPod isn’t connected to the jack (without the dock). If your stereo gets set to that input, and if something charged or metallic comes in contact with the end of the jack — think kid’s fingertips or some stray metal object like a set of keys set to rest on the shelf — then harmful feedback could occur. My headphone jack is set well out of reach, so I’m likely to be the only offender.

Thanks for your questions and comments, LD. I’m glad I could be of help.

17 inch MacBook Pro shipping late January

`17 inch MacBook pro

`17 inch MacBook pro

At last week’s MacWorld Expo, Apple announced they would be shipping a new 17-inch MacBook Pro laptop near the end of January. Rumors had been circulating prior to the announcement that Apple would be announcing a quad core processor laptop, but this was not it. The new MacBook Pro is built around a “unibody chassis”, that is, it is carved from a single block of aluminum. Pricing will start around $2,800.

Battery Life

Apple Online Store

The big news was its battery life. Apple states its battery is rated to last “up to” 7 or 8 hours on a single charge, and that it may be recharged up to 1,000 times.  (Compare this to other laptops which may only hold a 3 or 4 hour charge with a recharge life of 200 to 300 charges.) You can watch Apple’s video regarding its battery design below.

Apple rates the battery for 200 charges per year, so at 1,000 charges the battery will need replacing in 5 years.  Of course users who frequently save to the hard drive will have to charge the battery more frequently.  If you use your laptop on weekends, you may find yourself recharging the battery for than 200 times per year, too.

Apple Online Store

Still, this is a pretty big boost in battery life, but, once the battery’s lifetime ends, you won’t be able to change the battery yourself.  You will have to take it to an Apple store or authorized reseller for replacement. This might be difficult for owners who live in remote areas. The battery costs about $160.

Admittedly, not everyone runs on their batteries every day. Deskbound MacBooks will find themselves plugged into a wall outlet.

Weight

The 17 inch MacBook Pro is also one of the heaviest MacBooks on the market. With its battery being 40% larger than previous batteries, and its block of aluminum chassis, it weighs a full pound more than the 15 inch MacBook Pro, but is still within the same weight range as other laptops in its class.

Blu-ray?

MacBook fans who were hoping for a Blu-ray DVD drive for high def video or data storage will have to wait a little bit longer. There is no Blu-ray in this MacBook, and there is no option available for one as at upgrade at time of purchase either (at this time).

Solid State Drive

The $2,800 model has a standard 320 GB (gigabyte) Serial ATA (SATA) hard drive, but two solid state drive upgrade options are available for $500 (128 GB) and $900 (256 GB). Though smaller in capacity, the solid state drives (SSD) provide greater durability and shock resistance over the standard SATA drives. Standard drives have moving parts, but sold state drives have no moving parts. Solid state drives are similar to the flash memory chips found in the digital cameras, or to the drives found in some iPods.

Memory (RAM)

The Apple MacBook Pro 17-inch model comes with a full 4 GB of RAM, and can be upgraded to 8 GB of RAM for an additional $1,200. So if you add the large solid state drive and the full 8 GB of RAM your new MacBook will cost about $5,000.

Most people will find the 4 GB of RAM sufficient, but for the frequent traveller I would recommend adding the solid state drive for its sheer durability.  More on the 17-inch MacBook Pro below:
