How to build your own RFID reader

DIY RFID

Do you have any idea on how easy it is to build your own RFID reader? Well, we stumbled upon some sites that’ll give you some clearer picture on how to make this thing happens. As pointed out by hackaday,

[Klulukasz] left a comment pointing to this DIY RFID reader that was a final project in 2006 for a class at Cornell University. It is well documented and includes not only a schematic and code, but an explanation of the design considerations used during the build. The project uses an ATmega32 and the parts list priced out at about $50 at the time. There were plenty of responses to theRFID spoofer post pointing out that there are readers available for $40, but we want the fun of building our own.

A bit more vague with the details but no less interesting is this other simple RFID reader design.

Scratch built RFID tags

[nmarquardt] has put up an interesting instructable that covers building RFID tags. Most of them are constructed using adhesive copper tape on cardstock. The first version just has a cap and a low power LED to prove that the antenna is receiving power. The next iteration uses tilt switches so the tag is only active in certain orientations. The conclusion shows several different variations: different antenna lengths, conductive paint, light activated and more.
