Everyone heared about the Arduino for Atmel. Now it’s posible to work with the modern PIC and use a arduino like board, the Jaluino.
„JAL (Just Another Language, version 2) is an open source programming language built for programming PIC microcontrollers. If electronics is your thing, JAL is for you!“
That’s cool, on http://blog.section9.co.uk/2010/03/iphone-rfid-reader.html you can see the work process in pictures. The RFID chip is from http://www.id-innovations.com/new%20launch.htm.
„The idea behind this project is to see what the iPhone’s serial is capable of and to try and have a little fun with RFID along the way. This reader works with the low frequency (125Khz) tags but I have a half working version for MiFARE Hi-Frequency as well.“
