Neon Jumper (AkeemKaleeb) Mac OS
The other day I found on my desk what looked like a credit card from one of those semi-cafeteria style restaurants. At this restaurant you present the card at each station when you order something and then present the card to the cashier when you leave. I turned the card over expecting to find a mag stripe or bar code on the back, but there was not one. I wondered if this was an RFID card. Instead of tossing the card in the trash, I became intrigued by the idea of reading the card. After some emails on the HacDC email list and some google searches for RFID readers, I decided to order the 'PN532 NFC/RFID controller breakout board - v1.3' from AdaFruit.
Seeed Studio BeagleBone® Green Gateway is a low cost, open-source, community supported development platform for developers and hobbyists. It is a joint effort by BeagleBoard.org and Seeed Studio. It is based on the classical open-source hardware design of BeagleBone® Black and developed into this differentiated version.

I should have done some actual research, like reading through the specs for the chip on the breakout board. I thought I could plug this into a serial port, wave a card over it, and out would pop some info. I found products that did that when I was doing my searches, but this is not one of them. I knew I would have to solder on some connectors, but I did not realize I would have to write, or, at least, compile some code.
The thing is, the chip on this board can not only read RFID tags, but it can read and write NFC cards. So if I can get over the initial hurdle of communicating with the chip, I will be able to explore both RFID and NFC tags or cards.
There are three separate things to answer or solve. First, how to connect to it? The chip (and breakout board) supports I2C, SPI, and UART (at TTL levels). Second, what should I connect to it? My options are an iPad or iPhone (with the RedPark serial cable), a Windows laptop, Mac desktop, or a Microchip PIC. The third question is what code to write or run? AdaFruit provides Arduino code to communicate with the PN532, but I do not have an Arduino. There is also libnfc (link). I tried to compile this on my Mac, but I do not a compiler set-up at the command prompt (I think is something to do with my latest XCode installation).
I am most familiar with UART, and this works on all of the hardware I am considering, so I decided to go with that for now. For the connectors, I added a 5-pin header to the UART holes, and I soldered on the jumper headers, so I could select between the communication options (UART, SPI, I2C).
This leaves the following possibilities...
- libnfc on the Mac. I had given this a quick try and found that I did not have a compiler set-up. At the moment, I am more interested in very basic connectivity, so I might get back to this later.
- new code on an iPad. The RedPark serial cable I have supports a UART rate of 57.6Kb/s. From what I can tell, the default for the PN532 is 115.2Kb/s. I am going to pass on this at the moment, since it looks like this might not work at all (unless I can lower the rate of the PN532 and keep that as the default).
- new code on a PIC. The upper limit of the PIC UART speed, when not using a crystal on the PIC, might be too low. I would have to understand that first. Then, if I did have connectivity, I would not have a simple way to show the results.
- new code on a Mac. This is what I am going to try first. I have worked with serial ports on the Mac OS X before, where the serial port was a BlueTooth device, so I have some code to start with.
Hopefully I will get something working eventually. I will post an update when I do.

If, however, remain the black heart, so you can directly bypass the automatic conversion with a special character such as a period, comma or colon after the characters.
Skype: Several options and functions
Similar to Facebook is true for the Messenger service Skype. Use the key combination (l), the “L” for “love” is, Skype converts the string immediately in a heart symbol around. Alternatively, you can find this and other emoticons on the left side of the input field. The classic, black heart of our character table can also be inserted. The shape remains unchanged.
Twitter: twittering with a lot of heart

The heart symbol as a sign of love
The shape of the heart symbol goes back to the fig leaf. The first signs of the cultural origins of the symbol can be found in the 3rd millennium BC. Already at this time fig leaves were used as decoration and in similar stylized form. In the 8th century, the model converts: Heart grapes and ivy leaves serve as inspiration for vases and other ancient art pieces. Here, the ivy leaf was in this period as a symbol of eternal love (ivy is a very long-lived plant). For both the early Christian and the Greek and Roman cultures plays the symbol at that time an important role.
In the 12th and 13th century found the ivy leaves in the Minne literature, preferably in love stories, mention. Illustrations of this historical epoch show leaves like this especially in red. So the color red was already at that time as a love symbol. The symbol of the red Efeublattes was in Europe from now popular. The extraordinary symbolic power of the heart, the psychology can be explained today with the similarity to the buttocks and the vulva of women.
But why does the heart symbol in our culture today such a large role? A question which can be explained in particular by the close connection to Christianity. Here the heart is considered the seat of good and evil of every human being. But that’s not all: According to Christian understanding, the heart even serves as a conversation medium between man and Jesus. Closely interwoven with it shows the resultant in the Middle Ages the Sacred Heart cult. Here was the heart of the Saviour as a mystical symbol of divine love for humanity. A production which developed over time into a mass cult and has to answer probably the biggest share of the distribution of the symbol.
End of the 15th century the heart symbol found himself on French playing cards, replacing the traditional to date picture of a drinking chalice, as he was common on Italian tarot cards. But not only here the heart symbol was the subject of printing and drawing. Its Continuing use in heraldry and its use as a watermark also increased the spread of the symbol. So diluted over time, the original religious significance – and it came to pass that the heart was henceforth regarded as a sign of compassion, dedication and physical love. A symbol that today’s interpretation is very similar and came closer with its inflationary use its present meaning.
By the way: As a stylized human heart the heart symbol was only from the 13th to 16th centuries in use. Before that they used pyramidal representations or even a pine cone, its use can be traced back to the anatomical findings of the Hippocratic school. In the Middle Ages faded these findings and as the medicine took over the heart symbol also on in her illustrations.
