Simple NetworkAble RFID Controller

Simple NetworkAble RFID Controller

Popular known as SNARC, which is designed by Lawrence “Lemming” Dixon at the Hackerspace Brisbane (HSBNE). SNARC provides a simple platform for network controlled RFID access. It has a microcontroller, Ethernet module, connector pins for an RFID reader (5V, TX, RX, and GND) and an N Channel MOSFET output on board. This makes it a convenient solution for applications where a device needs to be powered or triggered via an RFID card while its access rights are stored somewhere in the cloud, e.g. doors in office buildings etc. SNARC comes with an ATMega328p chip and Wiznet Ethernet module (both of which are used by Arduino as well), which makes it fully compatible to the Arduino platform. The ATMega chip comes with an Arduino bootloader, i.e. you can use your Arduino IDE and run Arduino sketches on the board, by simply uploading them through an FTDI cable. SNARC is not released for official sale yet, but apparently will be soon. So stay tuned. Or shoot HSBNE an email if you’re interested to get a prototype. However, A minor disadvantage is that you… Continue reading

Monitoring Xbox Live activity of your friends

If you like playing Xbox games with your friends on-line then this project might be interesting to you. This is an arduino based traffic lights beacon that indicates when your friends connects to Xbox Live and are ready to play. So you don’t have to check this manually green light tells you to grab joystick controller and start playing. As we mentioned, this is Arduino based stand with WIZnet W5100 network adapter. Simple API allows checking friends online status without using any authentication. Traffic lights has three diodes. So every one indicates different status. If Red is lit, then there are no friends online, if Orange – there is one friend and if Green is on, then there are two or more friends connected – means it’s time for fun. BTW, there are three meters attached to same traffic lights stand. They are indicating other importan’t data like download speed, download % and monthly download. But there should be another write about this. Continue reading

LED News Ticker – scrolls the latest news through LEDs

They say bad news has feet but embedd guys say internet news has LEDs? We got amazed by James Blackwell’s LED new ticker which brings live broadcast to you by scrolling the latest news headlines on an array of 1.32-inch bicolor 8×8 LED matrices. A PIC18F2525 was used as the news ticker’s main processor while harnessing the power of Wiznet’s WIZ810MJ ethernet module to gain access to the internet. This news ticker does not need any user interaction; once the switch is fired it immediately connects to the network, handling DCHP leasing while also setting up DNS details. Once connection is confirmed the news ticker will then fetch news headlines from the internet and updates every fifteen minutes. Oh by the way before I forget this news ticker won second place on Wiznet’s iEthernet design contest last 2007, news for something huh? If we call news papers as printed media we could call the news ticker as scrolled media. Continue reading
