Here is an updated version of a former experiment using an Arduino board and the Parallax 125KHz RFID reader. The tag information is sent through serial port to a Processing sketch. Each RFID tag is a 10 bytes data with x0A and x0D as start and end of message. Arduino program int ENABLE = 2; This is another Nokia 3G phone 6212 with near field communication (NFC) in the market, other than the previous one 6131. Image from Nokia Europe I’ll give a presentation on the topic of RFID for the Right Click – Open Source New Media Art Exhibition. It is the information I post previously about the use of different RFID readers and some simple applications made around them. Here are some of the images of phone card I collected with chips. Another Korean phone [...] Here is a modified version of the last J2ME RFID reader program. The program will issue a Http request to a PHP script to retrieve a record from a simple MySQL table. The table has the following information: E00401000765464C E0040100076583CF E004010007652E93 E0040100076531E0 E004010007651CB8 Based on the tag id in the first column, [...] Parallax has a simple 125 KHz RFID reader. The reader has 4 pins. VCC – main +5V power Whenever a valid tag is present in front of the antenna, the reader will return a string of [...] The last RFID post has a piece of code from nowhere. I try to explain the serial protocol between the UART of the compact flash RFID reader and the PDA. The serial communication parameter is 9600 baudrate and 8,N,1 standard mechanism. For each operation, you need to send out a command to the CF reader in [...] Another product I have tested in the RFID project is a compact flash card size reader for use with a PDA. The Hong Kong RFID Ltd. sold us this HF reader, HKRHR-CF17, with a number of tags for testing. In our testing, we use a Dell Axim X50 for testing. The CF connection is virtually a [...] This version is the wireless serial connection between a host computer and the Sonmicro reader. It makes use of a bluetooth to serial adapter, PROMI-SD101 from Initium. The adapter has an internal re-chargeable battery (5V). It does not require extra power connection from the Sonmicro evaluation board. A configuration software come with the bluetooth to serial [...] For the hardware part, the sonmicro RFID reader is connected to a computer (PC running Windows XP) through a BAFO USB to serial adapter. The antenna, which is extremely fragile, is attached on a prototype board and wired back to the reader board. The datasheet for the RFID reader module CY8C0105 has the serial communication protocol for [...] Finally, after all the teaching schedule, there is a little time for the project. We have found the sonmicro development kit Image from Sonmicro. as the initial platform to work on with the 125KHz environment. It is the most common one used in art scene, along with the Phidgits‘. Image from Phidgets. The first scenario is to use [...] |
