Revolution: 10 Single-Board Computers

Share from

Since the coming of the Raspberry Pi Model B, single-board computers (SBCs) have become a prevalent force in the development world. These pocket-sized devices have taken the online maker community in particular by storm, providing PC functionality to a plethora of open-source projects in amazingly compact, cost-effective, and low-power platforms.

It's not an overstatement to say these tiny computers have engendered a technological revolution of their own by pushing the limits of technological creativity achievable in the palm of one’s hand. As an added benefit, SBCs have served as cheaply obtainable educational tools for teaching the ever-important concepts of computer science to the younger generation. Test engineers, those seeking to build one-off projects, and hobbyists have embraced, and appreciate, this mini computer platform. Similar to how the smartphone changed how we use phones, SBCs are poised to change how we approach embedded systems development.

The following slideshow introduces a series of some of the most unique SBCs that have hit the market to date -- all which can be purchased for under (or very nearly) US$100.

Many people may have seen the recent Makey Makey analog touch keyboard and video. Video boards can be connected to any electrical conductor by touching the conductor, to give computer keyboard events. To play different games, or effect.
One is through the principle of the single chip microcomputer simulation keyboard, raises a few keys, and use touch form instead of the switch. Now we use a piece of the arduino and Touch the key USB shields, and this effect can be achieve.

Touch key USB shields with Touch as input method, which adopts double contact of the Touch switch, will Touch the client and server-side derivation, connected to two electrodes Touch, Touch two pole, because of the human body resistance, the Touch between the electrodes is, to some extent, current flows through the size can be detected by measuring the current Touch events. Makey's virtual keyboard is also use this method.

Arduino ProtoShield, it is match Arduino Duemilanove ,used to build prototype circuit,Can welded components on board directly .Through double-sided adhesive connection between bread plate and the circuit board.

Daily Life with Arduino Open Source

An artical "Recovering Data From a Broken SD Card Using Arduino" posted by EETimes, has taught us how to use Arduino open source in our daily life,expecially the use of SD Card.

Here are two methods for communicating with an SD card.

The typical method employed by your computer or most other devices is called SDIO (secure digital input output). SDIO allows for different methods of digital rights management as well as functional commands, such as write-protecting the card.

The other method of communication is through SPI (serial peripheral interface), a standard serial interface. Communication over SPI is much slower.

Severin Schols was aware of both of these methods, which is how he was able to retrieve data from a seemingly dead SD card. When his computer would no longer read it, he decided to attempt reading the SPI mode. To do this, he attached it to an Arduino clone using an SD card shield (expansion pack).

He started out just attempting to read the card information with a piece of code that came as an example with the Arduino. Surprisingly, the card information was displayed. This meant that even though his computer couldn't read it, the SPI interface was still functional. He proceeded to dump all the files off the card in hex format. At first an error prevented him from dumping all the files, but someone else pointed out that it was because he was not properly closing the files after he opened each one. Once the files were dumped as hex, he was able to use a quick python script to parse them.

He notes that there is another method that could dump the entire contents of the card in hex all at once, but for a 4 Gbyte card it could take days to complete.

All scripts that he used are available on his site. However, he probably just got really lucky that only the SDIO burned up, and not the SPI, too. You shouldn't count on this recovery method always working.
