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. The 2 way radios will operate on varying frequencies that are assigned in different countries differently. It is not necessary to tune the equipment for a particular frequency because the channelized operation is used in the 2 way radios. You can use the pre selected frequencies that is available in the 2 way radios by selecting with the help of push button.

The 2 way radios are useful in many ways,. It is mostly used by military and law enforcement personnel. But in recent days the 2 way radios are even used by many consumers for their daily uses. Apart from this the 2 way radios are more advanced than before,. The effective uses of the wireless technology of the 2 way radios are the best aspect of it. There is no need to worry about the restricting cord while using this device. This device is very cost effective as there is no bill to be paid monthly.

The Remote Control Helicopter are called as the RC helicopter. This is the most advanced type of helicopter available at an affordable price to make your kids feel happy playing. Playing with the RC helicopter is more fun. This RC helicopter is less expensive and are also small in size. Many has the hobby of playing with RC helicopter. These RC helicopters are available in many different types like mini RC helicopter, coaxial helicopters, 3D advanced RC helicopter, RC helicopter airframe, Syma S108 G RC mini helicopter and many more types. Both the kids and elders are more interested in playing with the RC helicopter.

You’d think a commercial that featured a 1/10th scale RC model of the car they were trying to sell would be about 1/10th as exciting as seeing the real thing, but Nissan Canada’s new spot for the Sentra SE-R proves that theory very wrong. In fact I’d rather watch this highly-detailed RC model tear around a neighborhood, drifting through corners and blasting through piles of leaves, than the full-sized version racing down an empty highway. The use of a 1/10th scale camera car and an RC helicopter for aerial shots is also a nice touch.

The ad was created for Nissan Canada by TBWA\Toronto who were kind enough to film a behind-the-scenes look at how the commercial was made, which you’ll find for your viewing pleasure after the jump.

Interactive Toy Concepts is back at CES this year, and if you remember from our last year’s coverage they were responsible for the Duck Hunter game which you probably saw in every store this past Christmas. Well this year they’re introducing a different take on the ‘hunting toy’ game with their Skeet Shooter toy. Instead of trying to bring down a flying duck, the Skeet Shooter launches 3 plastic discs in the air which you try and hit with your infra-red mini-rifle. Unfortunately the prototype had just arrived at the show and wasn’t in working condition so we couldn’t see it in action, but I’m sure it will be just as popular for Christmas 2010 as Duck Hunter was for 2009.

The company was also showing off their VRC or ‘Virtual Reality Control’ flying RC toys which are controlled via a Wiimote-like gyroscope-equipped remote. So instead of piloting your plane, or in this case your RC helicopter, around a hotel ballroom with a set of sticks which aren’t that intuitive, you simply tilt and pivot the remote like you would a yoke in an actual flying craft. As you can see in the photo the VRC toys were in better working condition than the Skeet Shooter, but both should be available sometime this year.

I recently had the pleasure to help out on a music video shoot here in the northwest, noteworthy not just because a great video resulted, but because we were shooting with two RED One cameras and a custom RC helicopter for aerial shots. It was interesting being behind the scenes and I thought I’d share a little of the fun. The video itself, for Mt St Helens Vietnam Band’s “Albatross, Albatross, Albatross,” can be viewed in HD over at Vimeo.

The opportunity to see a group of local freelancers and entrepreneurs coming together to make such an incredibly professional product was extremely valuable — technology has democratized and accelerated the independent film and music community to a degree I hadn’t realized. I was brought on because I had access to some special locations (most of the aerial and forest shots are near some family property in the San Juans) and so I could shoot a little behind-the-scenes video of the production. Go ahead and check out that video below.

The above contains video shot by me as well as production stills by both myself and the director, Matt Daniels of ThinkLab. Matt edited it, since I was taking forever.

We had two RED Ones to shoot with, which is rare to find anywhere, really. With careful lens selection, this allowed for some really great multi-angle shots without change in continuity or video quality. For instance, we had Marshall, the drummer of the band, wading in the water in extremely low light (torchlight). One camera was shooting handheld, up close with a wide angle, and the other was about 30 feet away, with a longer lens in a more stationary position. It allows the director and editor to work freely with the scene without worrying about continuity errors, and can also drastically cut down on the time a poor drummer has to be standing in freezing cold water at midnight.

Lastly, the all-digital process makes for such a streamlined workflow that, if we didn’t have to catch a ferry, we could have had a rough cut put together the next day — a huge benefit when you’re working directly with a client, as we were with the band. As one might imagine, this can lead to sloppy productions put together without the caution and care that comes with working in a valuable medium like film — and some people assume that because it’s possible, it’s expected. But that’s as far from the truth as the idea that a film medium guarantees a quality end result. Digital cinema tools simplify the workflow, but they don’t simplify the product.

The helicopter you see is owned and operated by AerialPan Imaging’s founder, Tabb Firchau. I subjected him to a brief interview:

So the camera on the heli is a Panasonic HVX, which accounts for the difference in texture and tone you see in the video. I noticed a similar effect while watching Planet Earth; the Varicams they used for much of the series weren’t able to be used under water, so they used some sort of smaller Sony (I believe) camera for those sequences. The video quality isn’t as high, but the Sony and HVX are far more light and compact than a Varicam or RED One — handy in those underground caverns, or when you need to fly it at 50MPH over water in an RC helicopter.

I was struck by the amount of specialized gear used by both Tabb and the RED operators (Mike Prevette on heli and DP Michael Ragen). Jury-rigged solutions for missing or broken parts, custom fast-charging battery packs, and the lenses… oh, the lenses. And of course, it was interesting seeing the familiar forest and beach we were tramping around on metamorphose into the evocative landscape of the video.

It’s amazing how democratized high quality stuff like this has come, with the advent of (relatively) affordable HD cameras like the RED and pro editing and effects software that can be brought with you to the field. Thanks, crew — it was a fun and interesting look at the soft underbelly of cinematic production.

Just yesterday we featured Bandai’s cool remote-controlled heli-robot Sky Armor, and now the same company (its subsidiary CCP, to be exact) announced the Mission Carrier SWAT [JP], a combination of a truck and helicopter. And this toy is even better than Sky Armor.

The cool thing about the SWAT truck is the sound and the elevating deck: Push a button on the remote to make the panels in the back of the truck open and reveal the mini helicopter inside of it. The helicopter can then be controlled just like every other RC helicopter (for 5 minutes after a 30 minute charge). Needless to say, you can also let the truck itself drive around.

The Mission Carrier SWAT set will be available only in Japan from the end of this month (price: $90). Contact the Japan Trend Shop or Geek Stuff 4 U if you want to get one shipped outside Japan.
