Michael Teeuw published a new build: Now that the MusiCubes tray is assembled and the RFID-sensor and LEDs are working as expected, It’s time to add the last feature of the original concept: invisible capacitive touch sensors to control the volume of the music. See the full post on Xonay Labs blog. Be sure to […]
A short application note from Coilcraft about transponder coils. Link here (PDF) Radio Frequency Identification (RFID) is the system of using radio signals to send information identifying a particular situation or item. It can be used to track and locate any item including material, people and animals. The RFID transponder coil is part of the […]
Erich Styger writes: Playing with RFID and NFC is definitely fun?, and they are everywhere! For a research project I’m exploring different RFID tags and solutions. I several types around for a long time, but never found the time to actually work on it, so last nightI thought I give it a try, and I […]
Luke has published a new build: I wanted a simple way of quickly logging on to my computer without having to typing my password in and did not want to have no security either. There are various products on the market that would solve this problem from fingerprint readers to proximity dongles but i decided […]
Here’s a cool automatic feeder for your cat that dispense food in exchange for a wiffle ball by Benjamin Millam. He wrote a post on his blog detailing its assembly: I used an Adafruit RFID reader to detect RFID tags embedded in the wiffle balls: the balls are cut slightly, enough to slip in an […]
In this video Craig demonstrates his custom DIY RFID smart lock project: The goal of this project was to design an inexpensive rfid door lock which could be opened via smart phone, and have all activity logged w/o utilizing any 3rd party servers or cloud hosting. Via Hacked Gadgets.
Shawn McCombs blogged about his DIY Arduino RFID card door lock system 100 cards build. Via Hacked Gadgets. Check out the video after the break.
Boris of Open Electronics wrote an article on his stand-alone access control with RFID project: RFID Tags are increasingly used for many applications such as identifying objects by means of a code or access control. In logistics RFIDs allows asset tracking, or monitoring conveyor belts; in shops tags are often used as anti theft. RFIDs are […]
Ambient Backscatter – Wireless power and communication with no batteries Ambient Backscatter transforms existing wireless signals into both a source of power and a communication medium. It enables two battery-free devices to communicate by backscattering existing wireless signals. Backscatter communication is orders of magnitude more power-efficient than traditional radio communication. Further, since it leverages the […]
125 kHz RFID reader based on ATtiny13 by Vassilis Serasidis This is an 125 kHz RFID reader that is based on ATtiny13 micro-controller and an LM358 Operational Amplifier. No special RFID chip is used. The reading, decoding and printing the unique ID from 125 kHz RFID tags is made entirely in software by ATtiny13. Via […]
OpenBeacon is a comprehensive open source platform for active RFID applications operating in the license free 2.4GHz ISM band. The project involves base station hardware, as well as active tag hardware. OpenBeacon is based on Open Source software and a very flexible and reprogrammable lowcost Open Source RFmodule. The firmware sources and hardware schematics are […]
Zach is working on a RFID project using the RDM6300 RFID to UART module and a PIC 18 development board. Once I verified that I could receive a single card’s data, I set up a demo with three RFID tags programmed into the PIC so that it would toggle an LED based on which card […]
Benjamin made a small update on his NFC TI TRF7970A breakout board. The board is designed to provide you access to RFID and similar RF protocols. Benjamin has 15 boards he is willing to giveaway, so contact him on his blog if you’re interested. It is just a little update on the new board TI […]
Read and write 13.56 MHz RFID cards with OpenPCD: OpenPCD is a free hardware design for Proximity Coupling Devices (PCD) based on 13,56MHz communication. This device is able to screen informations from Proximity Integrated Circuit Cards (PICC) conforming to vendor-independent standards such as ISO 14443, ISO 15693 as well as proprietary protocols such as Mifare […]
Here are some compact 125KHz RFID readers with built in antennas. They require no external components what so ever to function. It uses a 2 wire interface supporting ASCII, Magnetic ABA, and Wiegand26 formats. Being priced at around 20 euros doesn’t make them cheap. Via Electronics-Lab.
Aaron decided to hack a cheap USB RFID reader, by using the Logic Sniffer to figure out the internal IC protocol. To make it useful for his projects he decided to hijack the internal bus that has the initial RFID decoding. After some poking around he was able to find the UART TX transmitting pin. […]
The nRF24LE1 is a single chip radio that can be used with a microcontroller for low power wireless stuff. It has lots of extras like an ultra low power analog comparator for voltage level system wake-up. Nordic Semiconductor provides an RF protocol stack and applications for microcontrollers. Via MDFLY.
If your kids are RFID enabled, here’s a project to give you peace of mind: the Kid-e-log by tronixstuff. Using an Arduino, EEPROM, RFID reader, real time clock chip and LCD readout you can keep electronic tabs on the kids by having them clock in and out of the house with RFID cards. A comprehensive […]
Chris Paget presented a talk at Defcon 18 on RFID and the security implications of long range reading of enhanced driver licenses which have embedded 900 MHz RFID tags. The video is divided into four parts totaling about 45 minutes. In addition to part 1 above, here are links to parts 2-4: Part 2 Part […]
Here’s our first test of the USB to serial mode of the USB Infrared Toy. We used it with a UART-based RFID card reader. Pictures and a sample Python script after the break. The USB IR Toy is $20, including worldwide shipping. Every sale supports this open source project.
