the laptop that could change the world - lithium iron battery

It has taken more than two years, but the "One Laptop Per Child" initiative has finally been released
Expected laptop: olpc xo-1. The XO-
$200 per person but limited time-until Dec. 31, 2007 —
People can use the promotion of "donate one, get one" to donate $399 (
$200 is tax. deductible).
In a developing country, a laptop is given to a disadvantaged child while OLPC gives you another laptop as a thank you
Your gift. (
Think about PBS pledge drive and they give you a set of DVDs with a $200 donation. )

Personal Technology Center.
In this "I, I, I" festival, this is of course a different business model: you don't buy things for yourself, you buy technology for the children you need, provide the bonus of a gift laptop for your family.
Please note that this is limited
The time offer is the only way you get the XO.
In the foreseeable future.
People can still donate laptops after the end of the year, but they won't get them as gifts.
Click here to enter the website of the "Give One, Get One" program. The OLPC XO-
1 is an interesting mix of opposites.
On the one hand, the technology it contains is almost not enough in today's terminology (sub-500-
MHz processor with only 256 MB of RAM and 1 GB of flash storage)
Although this is enough for the ultimate recipient of the laptop, it is a child in a developing country who has never used a computer before.
On the other hand, it includes features in laptops that are worth $2,000 or more.
It's wrapped in a solid exterior, a splash-, drop-, and hot/cold-resistant.
LED backlight display;
Compatible with 802. 11b/g Wi-Fi;
It also offers 802.
11 s "mesh network "-a type of peer-to-
Peer-to-peer ad-hoc networks requiring zero configuration.
It uses so little power that an external manual generator or solar panel can power the system.
The screen can lie 180 degrees flat on the keyboard like a tablet;
In this configuration, the laptop can be in the "e-book" mode.
You can scroll the text with the included game-style D-
But there is no touch on the screen to save costs --
Sensitive like a tablet.
It is designed to be used in broad daylight.
For my test (
Indoor, Laboratory)
I used a bright enough LED backlight, although it looked a bit dim from the wrong point of view.
The screen pivot and hinge help ease this problem.
If you think you bought it full
The net cost of a featured laptop is $199, and you are deceiving yourself, but for children within the target age range (
6 to 12 years old), the XO-
1 as attractive as the other "most popular target" Apple iPhone in 2007.
Bright and friendly in color, rubber-
The sealed keyboard prevents the beverage from splashing and the keys are responsive.
When I had to take xo I got all the mothers
Come back from my 9-1year-old tester (my daughter).
I think this is an exciting recognition from the target market. The XO-
1 is designed and built to work in any environment where you find a child, including-
Room school with wooden tables, mud brick cottage or dirty floor of sunlit soybean fields.
The antenna on both sides of the screen doubles as a screen latch for the laptop so that the kids can swing the XO-
Built around it-
In dealing with and giving up.
Falling from child height is unlikely to break the impact-
Resistant to plastic housing.
Both the three USB ports and the headphone and microphone jacks have the same antenna, so all ports are protected. The three-
The panel touchpad is capacitive in the center (touch-
Sensitive like most touchpads)
, Although the three panels are resistors together: you can use a non-conductive stylus, or even a wooden stick (
There is no stylus attached to the device)
, Draw or move the cursor.
There are many new symbols on the keyboard, including a row of buttons that represent the neighborhood, the classroom, and the individual.
These buttons modify the GUI so you can see the whole world (over Wi-
Fi or mesh network), local users (
If you are in a classroom environment with an olpc xs school server)
Or what you are doing now or in the past.
So far, whether a laptop is really in the hands of students depends on the education sector or local organizations in each country. The XO-
1 in its intended environment, the teachers and administrative departments of the school promote shared learning and communication between students, which is really their own.
The mesh network of laptops can help students collaborate on music, writing and many other activities.
Like Bluetooth.
If you can "see" other laptops wirelessly, you can connect to them --
But there is no all the tedious configuration needed for Bluetooth.
OLPC designed the system as a laptop because it wants students to bring their computers home and involve their families in their work and entertainment activities.
When it comes to activities, XO-
1 use the active metaphor instead of calling its open-
Application ".
"The custom Fedora Linux-based interface is a more elegant implementation of Linux than the gOS we see on Everex gp: both operating systems use the taskbar with a row of icons at the bottom (à la Mac OS X), but the XO-
The interface of 1 abandons the flashy graphics with the "jump" icon, so it is more responsive and practical in the end.
Chat, browsing and other activities (Internet)
, Write, draw, count all fromexplanatory. The XO-
1. have a music program called TamTam;
They range from simple beats-
Make a rather complicated music sequencer and a keyboard to smash toys.
The scope of application includes teaching programming, also from simple TurtleArt (
It uses the old logo.
School programming language used to teach primary programming in early 1980)
For complex Pippy (
Python is one of the main programming languages of the internet, used by Google and YouTube) interactive interpreter.
There is a recording function that can be built
In the camera, microphone, or both, pass the message between the child's teacher and the parent, or save the child's own memory. Internet-
Connected children will be able to download and install additional activities from OLPC's wiki
Based on the support site.
Downloadable activities on the support site are open-
Source code program specially developed for XO1 platform. The XO-
The 1 internet browser is a highly customized version of Mozilla Firefox.
Flash support-and Ajax-
Websites such as YouTube and Google Maps;
Slow but available performance. Word-
On smartphones, processing performance and general browsing are as fast as you expect, that is, fast enough.
The original prototype shows an integrated hand crank to be XO-1.
Unfortunately, this feature is not available in the shipping model, which comes with an AC adapter, but XO-
1 will still run out of external dynamic energy such as hand shake or 1 feet-
Generator-
Laptops going to developing countries may offer some features.
As part of its deployment for use in developing countries, XO-1 runs on 8-to-11-
V power system
From the hand or foot crank of the solar panel to the car battery)
And efficient.
I measured the power usage of 18 watts while the battery was charging, and measured the power usage of 6 Watts after the battery was fully charged.
This is far from the energy usage of 60 W to 100 W.
Efficient value desktop.
In contrast, the Asus Eee PC 4g uses more than 23 W when charging and 14 W when charging. The XO-1's LiFePO4 (
Lithium iron phosphate)
The battery is more eco-friendly than NiMH or NiCd and it will support more than 2,000 charging
Charging cycle. By contrast, 800 to 1,200 of the battery technology you get, such as lithium batteriesion.
Untrained personnel (
Maybe a older child)
XO can be repaired-
1 on site: loosen the four screws with your hand and open the screen border (
All electronic devices that save the keyboard and battery are on the screen).
After the screen is turned on, the backlight can be replaced with a $2 part, and if one is lost, there are additional screws in the case.
The motherboard with integrated CPU pops up as a whole and is also a user-
Replaceable so you can easily take two and a halfworking XO-1 laptops (
Say one screen is broken and the other motherboard is blown up)
And choose a good one from this pair.
I must reiterate that this is a donation, not a real one --
Blue consumer PC because we came to XO-
1 biggest drawback for users: 30-
One-day replacement warranty, but you can do it yourself once it's done.
You can try wiki.
Basic support sites for updates and communities-
But since OLPC is not a consumer PC entity, you need to handle the technical support yourself.
OLPC claims to charge-
Based on technical support services, but this is in the future.
As part of a "Give One, Get One" promotion, donors will receive one
T-annual subscription
Mobile Hotspot Wi-
Fi network so you can use your XO-
Starbucks cafes and airports across the country.
Also, if you just want to donate $200 (or more)
Each laptop and gift XO not received-
1. OLPC will spend the full cost of providing a laptop to children at $200 per unit.
In this case, your total contribution is 100% tax. deductible —
Of course it depends on your local and federal tax laws.
Compared with competitors, XO-
1 has the advantage of actual availability.
There are two major blows to Intel's Classmate PC: reference design only (
Original equipment manufacturers such as Asus or Dell still have to build brands)
So far, it's a vaporizer.
Classmate PC has the advantage of doing x86-
Compatible, so it will run Windows XP or various versions of Linux (the XO-
1 can only run its custom version of Fedora Linux).
The $400 Asus Eee PC is a better option for adult users as it is now available from public sources like NewEgg and still available to the public after December31, 2007;
In addition, it comes with a set of programs including Google Docs and the full version of Firefox.
Charity aspect of XO
1. However, it cannot be denied that Eee PC is not like XO-1.
If what you want is a cheap system, you can also choose either on eBay or low-
New desktop like Everex gp, but XO-
1 is notable considering the target market.
Could be the biggest blow to OLPC XO1 (
From a selfish point of view)
As a consumer PC company, OLPC is not a consumer PC company, so there is a disclaimer everywhere on its website, saying that although it will try to give you the gift PC before the holiday, delivery is not guaranteed.
It is guaranteed that your contribution will lead to the new XO-
Provide 1 PC for poor children somewhere in the world.
If this is a complete
Bad comparison review, I might nod my head to Eee PC for adult and OLPC XO
1 for children, but XO-
In the strict definition of this term, 1 is not a consumer PC.
$399 in donations (50 percent tax-deductible)
You will be donating money to a charity whose goal is to get laptops into the hands of children around the world, as a side benefit, as a gift, you will buy the same laptop for your child. After Jan.
2008, you can still contribute to OLPC's efforts on money, but you won't get XO-
As a gift to yourself or your child.
Either way, if you buy a personal computer, you won't be able to choose which country your charity laptop is going to, but if you donate 100 to 10,000 or more, you can choose where they go. The OLPC XO-
1 The rules of the game have been changed;
This is for sure, just like other laptop manufacturers and chip giants like Intel (
And its Classmate PC)
Develop competitive products.
What remains to be seen is whether OLPC itself or its competitors can put laptops in the hands of students around the world.
Just like other game changers and version 1.
0 products, large-scale adoption will be the key to the success of the "cheap education laptop. "While the XO-
1. it's attractive. it's a child.
Friendly, choosing which platform to use ultimately depends on the bureaucracy of the target country.
Unfortunately, for OLPC, lobbyists, marketing and PR agents have to spend money, and Intel has a lot of money.
So if Intel is able to get a Classmate PC laptop through the reference design and prototype phase, it can still gain an advantage.
I would say that this gives OLPC about 6 to 12 months to get the appeal it needs to build before Classmate PC and its ubiquitous x86 technology catch up.
No matter who "wins" at this stage of the computer war, in the end, children in developing countries will begin to familiarize themselves with and adapt to the technologies enjoyed by industrialized countries.
Perhaps in this way, communication will become a dialogue, not a monologue from rich countries to poor countries.
It will be worth a look.
Bottom line: XO-
A laptop for each child (OLPC)
Initiative is a game.
The situation of vulnerable children in developing countries has changed.
You can also benefit in a limited time.
Advantages: there is very little energy to run.
Educational software is pre-installed.
Wireless network with mesh network. Flash-
Compatible browser pre-installed. Long-
Cycle Battery.
Solid structure.
Convenient service.
Cons: not compatible with store
Windows or Mac OS programs have been purchased.
Slow flash performance.
Not so noticeable for adults.
Not a consumer business model. oriented (
Customer Support).
Unless you donate a lot of money, you can't specify where the computer you donate goes.
For experienced computer users, a new way of doing things needs to be learned.
You must take action by December.
