Following the huge success of my RFID sniffer workshops, the first RFIDuino workshop will be hosted by Mediamatic in Amsterdam, on May 15th, 2009.
At this workshop you will assemble an RFIDuino, and start coding RFID applications right away on your Arduino. Bring your own Arduino and laptop!
The first workshop is already sold out, but a second is scheduled for June 19th.
