If you are looking to sniff for RFID information, this is the project for you! “In this study we show that the modeling predictions are quite accurate. We show how to build a portable, extended-range RFID skimmer, using only electronics hobbyist supplies and tools. Our skimmer is able to read ISO-14443 tags from a distance of $25cm, uses a lightweight 40cm-diameter copper-tube antenna, is powered by a 12V battery–and requires
I didn’t think I would see the day that Microsoft would get into the robot game. You can download the new Microsoft Robotics Studio now.
