What will be the future of cell phones?
What will the next version of the cell phone look like?

I'm not exactly sure. I think it's a case of innovation having to follow technology. Just because you want to hop in your car in the morning and let it drive itself to work, doesn't mean it's going to happen. Eventually it will, but not until the technology is there. Designers love coming up with all this fancy futuristic ideas of things like cars, but when it comes down to it, they end up just building a regular old Honda Civic.

Anyway back to cell phones. In order to see where we are going, we need to see where we have been. First a short history lesson.

This was basically the first cell phone. It was really big, heavy and expensive. You had to carry around a giant battery and could only talk with people if you were in a big city like New York. These made more sense when they were mounted in luxury cars.

In 1986 the first thing that really LOOKED like a phone was this, the Motorola DinaTAC, which took 10 years to develop and was nicknamed the Brick. I think i remember that the guy who invented it, based it off the tricorder from Star Trek. It was still expensive, costing over $3,000.

I still know it as the Zack Morris phone because of him always using it on Saved by the Bell.

But eventually technology progressed and the phones got smaller and cheaper. Still they were only used for calling. Because why would you want or need to use a phone for anything other then calling someone?

Then they got even smaller and there were new designs like the first flip-phone. You could fold them up and put them in your pocket, after you put down your little antenna of course.

Flip phones really hit their stride with the Motorola Razr. A small, cheap, easy to use phone that everyone had.

It had a camera and front screen and it was relatively cheap. This was when cell phone companies realized that they could make more money in the monthly cell phone bills then by selling the phones. Sort of the same story as computer printers costing $40 and then when you need to buy the ink it cost $25 for a little cartridge.

Then the screens got better, cameras got better and people shifted from calling more to texting more. So for texting, email and the internet they needed a fully keyboard.

There were some other early adopters out there that saw that the phone would eventually become a mini computer. I remember people having the Palm phones, but they never really caught on at that time. It seemed like they were a little early in the whole data phone plan idea.

There was also things like wireless bluetooth technology which could sync your phone to other electronics. It allowed for wireless talking and data transfer.

Then the era of the large, simple glass flat screen phones arrived with the Apple iPhone. No more keyboard to get in the way, this phone could transform itself to whatever you wanted. And since then, this has basically been the model for modern cell phones.original iphone, basic iphone, version 1, v1, apple, iphone, size

So what is going to happen next? Here's my predictions...

The future of the cell phone, future of cell phones, diagram 
I think that the most immediate technology that will come to phones will be the cell phone / credit card. By credit card i mean drivers license, health insurance card, bank card, birth certificate... No more wallets or purses, alright women will probably still have purses for their stuff, but all your important information will be on your phone. It will be a consolidation of your life's documentation.

But with all of this important information on our phones, we will need some way to protect it. And sci-fi movies have shown us the best ways to protect our precious information, retinal scans. You will put your eye up to the camera, a high-tech laser beam will come out and pass over your eyeball. Of course this means that if someone wants to steal your phone, they will then have to cut out your eyeball with a knife too.

The wireless charging docks already exist. There are versions made by Energizer and Duracell. The concept of wireless electricity was invented by Nicola Tesla decades ago.

His idea was to power an entire town with wireless electricity, but i guess he was just too ahead of his time. Today though, we have a special cell phone case and table top pad that when next to each other will charge the phone.
energizer wireless docking station, pad, case, future
I think that all future phones won't need the special case, the hardware will be built in. And this will really catch on only when Apple says it's cool and you need it. Then eventually you wouldn't need a dock, your entire home would be the dock. Your phone would start charging when you walked through the door.

This would also tie in with my bluetooth control of everything electronic. No only would your phone begin to charge when you enter your home, but you phone would start communicating. Downloading and uploading files to backup hard drives and turn your phone into the TV remote and the light switch. I'll call it SIRI 2.0. The software on the phone will eventually become like a real person. It will understand all of your commands.

Now who wants to be carrying around their phone with them while they are in their own home? Not me. So i see something like you set your phone down and your watch becomes the interface.
cell phone watch, stylus, wear, phone, wireless 
It's easy to move around with and small enough to forget about. Although i don't see that stylus catching on. I think that the future lies in screen projection or holograms.

I mean doesn't this just look like what your house will become in the future. You won't have a 50" TV, your TV will be however big you want it to be.
future of home phone, minority report, virtual screen
There's already lots of versions of this in the world today. You can even build your own table top version that uses a projector and a Nintendo Wii controller as the sensor. But as the technology continues to progress i think we will see a simple, powerful, easy to use version. future of cell phone, control screen with your hand movements

They already make cool screens that can bend and fold. This is more of the future of the cell phone interface. How the phone will look and feel.

Maybe it will be similar to the phones we have now, just clear and futuristic looking. This looks more like a work of art and actually not that futuristic. It's overly complicated.

Even something like a ring or bracelet that you wear seems overly complicated.

Google will soon release their Google Goggles, which will be able to merge the computer to what you see.

Instead of just looking at a movie theater, you will see the front of the building and a projection of what's showing, at what time and whether it's sold out or not. You won't even have to ask your phone, it will just do it. And it will remember your favorite types of movies and give you suggestions of what you might enjoy.
google goggles, glasses, screen, projection, transmit, wear, when, release, ever make
A phone in the future will be something that you can't forget. It will be come a part of you. Maybe a chip will be implanted into your arm. It will be all of your information, GPS, phone, computer... now it's starting to sound like one of those Sci-fi movies where the government controls peoples lives.
computer chip in body, arm, cell phone, part of you
Either this or we will just TELL the computer what we want, basically like in the Starship Enterprise. "Computer...turn on the lights." "Computer...make me a chicken pot pie." We will forget how to do everything manually and only know how to interact with software.

Until eventually the fate of the universe will rest in the memory banks of two droids and they will communicate with a hologram. I mean it wouldn't have been as dramatic if Princess Leia would have told Obi Wan Kenobi that he is her only hope, via Email. Attached is a PDF of the plans to destroy the Death Star, hopefully R2 got the Adobe update so he can read the file.

Human or "human-like" interaction is the key. The future of phones will eventually be able to simulate actually being in the same room as someone.

Spinning Wool - Night Photography

Penulis : Admin Ashish Chaturevdi on Wednesday, 16 May 2012 | 10:06

Wednesday, 16 May 2012

When i first saw this type of picture i was sure it was done with some type of firework or sparkler. Then i read the caption and it described it as "spinning wool." So i looked it up online and videos on Youtube and it turns out that it's made by spinning a lit piece of steel wool around in a circle. Here was my first attempts.



I had experimented with taking pictures at night before. About a year ago i did this Snowy Night photography, where i was using a flashlight to write my name.

So the idea is basically the same but the process is a lot more dangerous.

Setup:
  • 0000 fine steel wool
  • Metal harness
  • Wire string
  • Lighter
  • Hooded sweatshirt
  • Bucket of water!!!
Here's what i made as the wire and harness. I just used a coat hanger and some thin gauge wire. As it spins, the steel wool gets pushed to the end of the cage.

I remember reading from a survival book that you can start a fire with a 9 volt battery and steel wool. The charge shorts out on the metal and catches on fire. I remember being amazed that steel wool would burn. So you could use a battery to light it, but a lighter or matches works faster. Here's what the steel wool looks like after it's lit.
http://youtu.be/hBy6H7FXA5w



Now if i just left this there it would gradually turn orange and burn through in about 20 seconds. But by spinning it in a circle, you are adding more air, allowing it to burn faster and the whole process takes just 3 or 4 seconds. The reason these pictures look so cool is that the steel wool actually falls apart as it burns and it looks like a shower of sparks.


Now i didn't have the "bucket of water" when i did this but i definitely will in the future. Luckily it had rained the day before and everything was wet. All of those sparks hitting the ground is a super hot piece of metal and it stays hot for several seconds. It could very easily light something on fire if it were dry. And the hooded sweatshirt is so that if one of the hot sparks lands on your head, which is very likely.

Anyway here are the settings that i had on the camera.

Camera Settings:
  • Canon with CHDK
  • +-25 seconds exposure
  • f/6 aperture
  • ISO 250

I would say that you could do this with any digital point and shoot camera but the exposure time is tricky. My camera maxes out at 15 seconds normally. It would probably work, but you would have to crank up the aperture and ISO and it would most likely turn out grainy. So i turned on the CHDK software on my Canon S95 and set the exposure time to 25 seconds. I think that with the settings listed above it gave me a good balance between not overexposing the sparks but not underexposing the dark background. Also i probably should have turned on the RAW setting but i didn't since this was just a test. If i do this again though i would set it to RAW, which would allow for better Photoshop post editing.

As you can see the sparks fly about 30 feet depending on how fast you spin the steel. I tried different things from spinning vertical, horizontal and all different directions. The key is to get close to the camera, without letting one of the sparks damage it. I stayed on the safe side and stood +-40 feet away.

But i am definitely going to try this again sometime. It was fun and the pictures turned out better than i expected.

DIY - How to Make a Camera Polarizing Filter

Penulis : Admin Ashish Chaturevdi on Monday, 27 February 2012 | 11:18

Monday, 27 February 2012

While reading about making an ND Filter out of welders glass i also learned about how to take Infrared Photos. Then, while reading about Infrared filters i learned about polarizing filters.

Everyone always says that a polarizing filter is the most important thing to have other than a camera. But looking at comparison pictures with and without the filter i barely saw a difference, so i never really thought twice about it. But i do know that fisherman use polarizing sunglasses to reduce the glare of the sun and help spot fish under water.

A polarizing filter, like polarizing sunglasses, cuts down on glare and reflections from the sun. It is great for outdoor photography. There are also g

I realized that the best way to make the filter was to start with a pair of 3D glasses. I had a couple pairs of Real3D glasses at home.
Real D 3D Glasses Polarized
It turns out that the lenses in those glasses are circular polarized. There is also linear polarized lenses, i'm not exactly sure what the difference is, i think it has to do with what direction the light waves are allowed to pass through.
Real D 3D Glasses Polarized Lenses
When i made the ND filter and even for the IR filter i spent a lot of time trying to figure out how i would mount the filter to the camera. I thought of rubber bands taped to cups and all sorts of things. I finally made a simple mount with a PVC ring and some hard foam that would slip tightly onto the lens. The great thing is that this time i just did exactly the same thing. All the hard work of coming up with the idea was already done. So i cut another piece of PVC, glued in the foam and sanded it in about 10 minutes.
Polarized Lens DIY Make
I was planning on cutting the Real3D lenses and gluing them to the PVC but then i remembered that a while ago i bought a cheap set of lenses from Amazon that didn't fit any camera i had.

So after coloring in the PVC with a black marker i checked to see if the polarizing filter would fit. It fit just fine and wasn't too heavy.

To keep it from getting scratched i keep it in a cloth bag i had made for one of my old cameras.
Polarized Lens Case
This was at a nearby lake, while i was holding the filter a few inches in front of the camera lens. You can see how the right side of the pictures is much brighter because of the excess light reflecting off the water.
Polarized vs Non-Polarized
It was early in the morning so i'm not sure that the polarizing filter made that much of a difference. The filter helps the most during bright sunny days.

Manfrotto Tripod Review

Penulis : Admin Ashish Chaturevdi on Saturday, 25 February 2012 | 22:29

Saturday, 25 February 2012

On Slickdeals i saw this tripod (Manfrotto 7322YB M-Y Tripod with Ball Head) being sold for 50% off and free shipping from Costco. It normally sells for $70 on Amazon.

I like how compact it is and the adjustable swivel head attachment. But i'll have to eyeball the camera being level, especially on shots outside with the horizon.
