Recently i received 2 computer motherboards and one broken laptop. So i started doing the best thing for them , taking them apart. First came the notebook, which was quite difficult to take apart, lots of screws in lots of small corners, pieces screwed together from both sides, etc.

But after a couple of hours i was left with a 15,4″ WXGA lcd panel, one 512 MB ram dimm(i used this to upgrade a friends laptop), a laptop keyboard, a laptop battery, a laptop cd-rom, a wifi lan board, and lots of different chips taken from the motherboard. In fact i will post a list with all the parts at the end of the article, because i have an idea

Next came the two computer motherboards, i took those apart too and saved allot of interesting chips.

And now the idea: since i now have a bunch of parts i want to give’em to someone so it can make something interesting out of it. I also want to give that person a PCB from BKRtech. So take a look at the list and if something looks interesting and you have an idea let me know, I’ll send you the parts and the PCB.

You’ve probably seen the article about the Asus Eee PC and what can be integrated inside it’s case. But after you’ve done some modding and added different devices your battery probably doesn’t last as it was intended to last, so if you need to charge it in the car you either buy a commercial adapter or you make it.

This projects shows details on how to build an Eee Pc car charger. There are actually a small number of parts so the whole cost should be small.

With a DIY audio streamer, you can send your favorite tunes wirelessly from your computer to other rooms. Anyone can build this remote-control wireless streamer for less than a hundred bucks using just about any old Windows computer. You can buy or make a custom enclosure that matches the room’s decor and add a small LCD screen to show you what song is playing. Then throw in a wireless remote control, and start streaming your favorite tunes anytime and anywhere you want.

The first step on the project is joystick control of a servo over a USB connection. The end result which will make the project complete would be a RC rover monitored and controlled with a laptop and joystick on a WiFi network. The first step is already finished and the author managed to control a servo with the joystick.

Connecting a LCD display to the end of a printer-cable is a simple and effective way of providing additional functionality to your computer system. The printer-cable LCD can be mounted on your computer case or fitted inside a Jiffy-Box and displayed somewhere away from your case. Even the fully functional software interface is simple to install and configure. The parts used are a non-backlit 16 x 2 character LCD and a parallel port cable(printer cable).

This project teaches you how to build a lamp that can change color, and can be controlled by a computer. Simple Python and C programs for your PC or Mac are provided that let you program color patterns into the lamp. Implementing the weather forecast and other ideas are then up to you. Web scraping with wget is easy if you understand a scripting language. The whole project should cost under 100 euro, half of which is for the lamp (glass ball, LED module, microcontroller, and odds and ends), and the other half for the flash programmer if you don’t have one. So considering you already have a programmer, the project should not set you back too much.

If your an Electronics geek, you probably want to tweak electronics related stuff in every place you spend time. For example in your car, you probably are not happy with the information displayed on the dashboard. Maybe you want to know fuel consumption at a given time, or the air conditioning temperature or you want a unit that can control all this. Here is a nice project for this: t uses AVR microcontroller that is equipped with various sensors and LCD display which shows quite a bunch of info like momentary fuel consumption, momentary speed, journey time, passed distance and many average indicators. First working project version can be found here. Probably there will be another with more improvements.

It will be available in about 600 stores, as well as online, Wal-Mart said. A comparable Everex PC preinstalled with Windows Vista Home Basic and more memory costs $298 partly because the manufacturer has to pay Microsoft Corp. for a software license, so I think people will like the new computer and discover the goods of linux.

Both computers come with keyboard, mouse, and speakers, but without a monitor. As you already may know Linux is developed and offered on a open-source basis by individuals and companies around the world.

It’s being used especially on servers because of its high stability on long term use. The variant of Linux on the gPC is called gOS and is derived from the popular Ubuntu variant. It’s mostly oriented toward Google’s Web sites and online applications, like YouTube, Gmail and the company’s word processing program, all of which can be used only when the computer is connected to a broadband line.

The PC comes with a dialup modem, but gOS doesn’t support it. So most users likely will get online using other ways. Google’s entrance to the OS market is relatively new and I think gOS will be a great chance for users who would like to move away from Microsoft and windows to something new and better.

Wal-Mart spokeswoman Melissa O’Brien said it is stocking the computer in about one in eight stores to test the demand for an open-source product. The gPC has a low-end processor from VIA Technologies, plus 512 megabytes of internal memory, an 80-gigabyte hard drive and a combination DVD drive and CD burner. Everex says the processor is very energy efficient, meriting the “Green” part of the name.

here is a screenshot of the gPC or you could call it a gOS screenshot:

    This basic computer its based on avr chip Atmega32. For your understanding this is a basic language programmable chip computer which can run basic programs or scripts with the ability of displaying results on a RGB TV screen.
