The 2 way radios can both transmit and also receive the signals. They are unlike the broadcast receiver that can only receive the content. You can get the 2 way radios on stationary base, hand held configuration and mobile as well. The hand held portable 2 way radios are also called as the walkie- talkies. The 2 way radios has the push to talk button for activating the transmitter. The mobile phones are the best examples of the 2 way radios which can transmit and also receive the content. The 2 way radios also uses two frequencies to carry the conversion from both the direction at a time.

The 2 way radios are available on different types, system and technologies. Some of the types of 2 way radios includes the Conventional 2 way radios, Scanning in conventional 2 ways radios, talk back on scan radios, Trunked 2 way radios, simplex 2 way radios, duplex types, push to talk 2 way radios, Data over 2 way radios.

Three years ago I knew nothing about cars nor cared for them much, until Stephanie Walsh got me interested in Starions. Her ex said back then, ‘You gotta know about cars or some mechanics will rip you off’. Sadly, Stephanie passed away in 2007. I have decided to do an electric car project in her honour, as she was a wiz at electronics and taught me much in that area also. Together with Nathan Bolton we are now converting my rare Starion to full electric drive. This is the first video of a series I intend to do following the conversion of my car. We now have a Kostov 10.7 inch electric motor that used to be in an electric bus for the Sydney Olympics. I’ve got lithiums on the ship from China, a Curtis controller and other bits and pieces coming for the air-con, power steering etc. The car has been a headache in some ways, getting it up to spec, re-spraying in places etc but overall it should look good when done and will comply with local laws for on-road every day use. This video covers engine mounting estimations, rear-battery compartment construction, and Nathan’s teaching me to weld (and as someone commented, “You had better hide your boobs or sparks will fly’ ;-P ). The adaptor plate for the gear box has already come back from the machinist and in this video we drop the motor in and temporarily position it to get a rough estimation of available space – there should be plenty for the controller and batteries, along with a home-designed cooling block for the controller.

So, you’ve just taken in a shiny new iPad and impressed by its beautiful display. There are several possible sources of content that you will want to convert for viewing on this big screen, and the best tools to use for the job will often be determined by the type and source of that content.

The most common types of content include DVDs, downloaded digital video content (such as that downloaded from the web), content recorded from a TV using a digital video recorder (DVR), standard digital video content and high definition video content. We will be discussing each of these content types in turn, and our recommended tools for each.

Part II – Converting DVDs
Part III – Converting Standard Digital Video and HD Video Content
Part IV – Converting Recorded TV Content

Part I. Understanding the formats compatible with iPad
You know that 9.7-inch high-resolution screen makes iPad perfect for watching video, but that doesn’t mean that every type of video file will play on your iPad. The iPad supported video formats are:
H.264 video (up to 720p, 30 frames per second; main profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats);
MPEG-4 video (up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, simple profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats).

Part II. Converting DVDs
One of the most common sources of iPad content will be DVDs. Although the legality of ripping the content from DVDs varies in different jurisdictions, many countries outside of the U.S. have no specific restrictions on the conversion of DVDs that you already own into other viewable formats.

On the Mac platform, the most commonly used tools for DVD extraction is MacTheRipper. MacTheRipper is a simple DVD ripping tool; it does not actually convert video, but merely extracts it from the DVD. The use of MacTheRipper is relatively straightforward:  Simply insert a DVD and start the application and you will be presented with a main screen of MacTheRipper.

MacTheRipper defaults to full disc extraction, it will simply extract ALL content from the DVD. To extract a title from the DVD as a specific file, you instead need to click the “Mode” tab and choose “Title – Chapter Extraction” from the pull-down menu. The result of this operation will be in MPEG-2 format, and can be viewed through any software application capable of MPEG-2 playback, or converted using one of the tools discussed further in Part III.

Fortunately, there are other end-to-end iPad conversion solutions available. DVD to iPad Converter for Mac from iFunia is the second and better option. It provides an integrated solution to preform the extraction of DVD content and conversion to an iPad-ready format.

 
The iFunia DVD to iPad Converter program comes with an intuitive interface with 3 easy steps. You can simply insert a DVD and start the program, it will then read the inserted DVD or DVD folder, then select the iPad presets and output destination folder and click Start button. That’s so easy! You can learn the detailed step-by-step guide from iFunia’s website.

In addition to the ability to take content from a DVD directly to an iPad-ready format, iFunia DVD to iPad Converter for Mac also offers simple movie editings, the ability to queue up multiple tracks from a DVD, support for the finetune of video and audio settings and the ability to extract audio track compatible with the iPad.

Part III. Converting Standard Digital Video and HD Video Content
Standard Digital Video Content refers to the various types of digital content that can be stored on a computer, such as that obtained from web sites and already pre-extracted from DVDs into other non-iPad-ready formats. HD Video Content means high definition video. The HD video generally refers to any video system of higher resolution than standard-definition video, most of them are at display resolutions of 1280*720 (720p) or 1920*1080 (1080i or 1080p), and obtained from AVCHD and other HD digital camcorder.

There are many free tools for iPad video conversion on Mac, like iSquint, VisualHub, MPEG Streamclip, etc. But iSquint and VisualHub have been discontinued and are no longer for sale, while MPEG Streamclip cannot convert HD video content. Maybe you can convert HD video from most digital camcorders through Apple’s iMovie HD application included in iLife ’06 or above. But iMovie does not provide any additional default presets for higher-resolution iPad, also the conversion times will be quite slow as it uses the underlying Quicktime engine.

So far the best option for HD and SD video conversion for iPad maybe iPad Video Converter, still from iFunia Corp. It’s designed specifically for Apple’s new tablet, provides standard presets for iPad encoding, as well as simple video editings. For the average user, the main iPad Video Converter screen is nice and clean, providing just the necessary basic functions. You can simply drag in the content that you would like converted, selecting your basic output options, and hitting the “Start” button.

Part IV. Converting Recorded TV Content
Another type of content that many iPad users will want to convert is content recorded from broadcast television sources, such as over-the-air, cable, and satellite programming. This content can come from digital video recording software installed directly onto a Mac, or from an external DVR such as a Tivo, and EyeTV allows for the handling of either.

EyeTV is probably the most popular solution for recording TV content on a Mac. Selecting a show from the online TV guide will have the advantage of ensuring that the particulars of a given recording for you, and when scheduling a recording, you can also tell EyeTV to export to an iPad format immediately after it finishes the recording. The converted video will also be automatically imported into iTunes with the correct name, description and show tags filled in from the TV guide information, ready to be synced to your iPad device.

 
Conclusion
With the iPad’s new release, the number of options and conversion tools will continue to evolve. This article is not intended to be a comprehensive guide to every single possible tool available, but simply to provide some information on the more popular tools that are used for the various types of content and video conversion projects and provide some guidelines on the methods for obtaining the best results from these.
