Pong with Lasers

wallofpong

Pong that works anywhere

This version of the game pong was created by a senior at Cornell University. It uses a laser that displays the pong ball on any surface. Using the controllers which are attached to an Atmega32 microcontroller you can hit the digital ball back and forth to each other. Each of the controllers for pong has sensors so it can detect where they are and let the processor know when to change the direction of the ball.

A chalk board works best to play this game on as you can draw the boundaries and let the computer know exactly where they are. The system is built in 3 parts. First there is the laser project platform, next is the two hand held paddles and then the microcontroller connecting them all together. The laser beam is projected on to a mirror which is controlled by 2 motors on an x and y axis.

The sensors in the paddle/controller are light sensors which pick up when the laser ball hits it so that the ball can be sent back to the opponent. 3 sensors are in each controller so that the full length of the paddle will actually send the ball back to the opponent.

Overall I am impressed with this and wish the students well with their project.

TV that Hides Under Your Bed

Hidden TV
LCD and Plasma screens are great because they are so slim they save a ton of space. TVs can now be mounted on the wall, with in mirrors, on the ceiling and now, even under the bed. The video after the jump shows a large TV that tucks away under the bed when you do not need it. At the push of a button it slides out and lifts up to allow you to watch TV. Once hidden, it is completely out of the way and out of site which is ideal for some types of room.

Receive Text Messages on the GPRS iBall

iball-gprs-sms
The GPRS iBall suggests by its name that it has some kind of GPRS abilities. If you guessed this then you are exactly right. In the base of the iBall you can put your SIM card. Each time you receive a text message the iBall displays the text message around the globe in fancy flashing colours. However, I dont yet see a way to send messages so it could be a bit of an eccentric device and not much use unless you have a spare pay as you go SIM card kicking around.

Ultra Short Focus on the Sanyo LP-XL50 Projector

Sanyo LP-XL50
When using a projector in a home cinema or classroom situation you often find that the projector gets in the way when there is just a small group of people. Also, the presenter cannot walk past the projector and screen with out blocking what is on screen. Sanyo have created a projector with a very short focus allowing it to be just 8cm away from the screen. At this short distance it is still capable of projecting an 80 inch screen with an ANSI lumens rating of 2000 which is fantastic. The inputs on the projector are fairly standard which is good. There are 2 VGA inputs, component, S-Video and composite connectors. Also the LCD projector has a built in 2 watt speaker which wont exactly blow you away, but is acceptable for creating some sound.

Haier P7 Pen Phone – Weird

Haier P7
Haier have created the P7 pen phone. I must admit, I have no clue who Haier are but thats beside the point. The Haier P7 is a fully functional mobile phone which has a ton of features crammed in to it. The first thing you will notice is that its a weird shape and is aptly named the Pen phone. I guess the reason for this is so you can clip it on your shirt pocket? maybe? The P7 included a digital camera, 90 minute voice recorder, an LCD display and has a standby time of about 150 hours. Talk time for this phone is around 4 hours which is acceptable. Apart from that its just a unique and fairly weird phone.

Sony Introduces a 70 Inch Rear Projection Telly

Sony 70 Inch SXRD
Sony have introduced a 70 inch rear projection TV which is 40% slimmer then a version launched last year. I am impressed with how thin this is for being rear projection and it certainly is a nice competitor to the LCD screens that we see around. The reason it will do well against LCD screens is because it is priced at $6000 which is a lot less then an equivalent LCD screen.

It weighs 200 pounds, so it quite a beast in weight, but they have created this one to look good too. Sony calls it floating glass and as can be seen in the picture above it certainly does look nice.

The Invisible PC

The Invisible PC
If you look closely at the picture above you might spot the PC stashed away behind the flat panel. The invisible PC is built by Trident and is just 1 inch thick. It has industry standard mounting holes so that it can be put in between the screen and arm. The PC does not have or need a fan which helps to keep it quiet and out of the way. The PC is not powerful though. It has just a 1.5Ghz Via Eden processor which will do well for certain things. One of the main uses is for shop displays where the screen can be set up and a simple presentation displayed to passers by. With the option of a 40GB drive there is plenty of space to work with.

Panasonic HD Digital Camera – DMC FX100

panasonic lumix fx100
The latest camera from Panasonic is the Lumix FX100 which boasts a 12.2 megapixel CCD and also the ability to record high definition video. It has 27Mb of internal memory which isnt really that much considering the 12.2 megapixel capabilities. Of course you can extend the memory by the way of an SD memory card which will allow you to make full use of the HD recording capabilities. The video its self is recorded at 1280 x 720 pixels but it is only at 15fps.

Flexible Sony OLED – Video Demonstration

Flexible OLED
A few days ago I wrote about a new Sony OLED screen which had been announced on the Sony JP site. I had a question at the time about the response time of the screen and what video would look like. This morning I came across a nice video over at youtube which demonstrates the OLED screen being flexed around while playing video. The results are quite amazing. Just a quick reminder of what this screen actually is and then the video follows after the jump. The OLED screen is sealed in plastic rather then glass like other OLED displays. This allows for it to be flexible. The main reason glass was used was to prevent moisture getting inside and damaging the components that make OLED screens work. The screen on the video has a resolution of 120 x 160 pixels with a pitch of .318mm. The diagonal on the screen is 2.5 inches.

New Sony Flexible OLED Screen

Flexible OLED
Sony have unveiled an OLED screen that is flexible. OLED displays tend to be made out of a sealed glass which protects the materials inside from getting moisture on them which can basically kill them. Sony managed to create the screen on to a plastic which allows it to be thinner, lighter and bendable as seen in the image above. The screen is a full colour display also. The prototype is has a resolution of 120 x 169 with a .318 mm pixel pitch. I do not have details on how quick the screen can update (refresh rate) but this is certainly interesting to see this kind of technology appearing.

Flying in Style

VIP Boeing
If you want to feel like a VIP and have a ton of cash laying around then you might want to check out the Boeing 747-8 VIP. This is a business jet and very luxurious. Inside they feature vaulted ceilings, spiral staircases and video wall displays. The cabin is over 465m2 which allows for plenty of office space and entertaining space while on those long haul flights. One more picture after the jump.

Dell Ultra-thin LCD Concept

Dell LCD
This LCD created by Dell is ultra thin at half an inch thick. It has 4 times the current HDTV resolution, allows integrated peripherals around the display, allows you to daisy chain multiple screens and all goes through a single bidirectional cable. A lot of parts have been removed from the screen to cut its size and weight down although I am unsure how much of that is packed in to a box that could be stored under the desk. Either way, the screen is nice to look at especially with the surround that appears to be glass.
