Akiba @ FreakLabs introduced a new Arduino compatible board named Freakduino-Chibi. This board has open source 802.15.4 protocol stack and integrated radio. The stack and board are designed to make it easy for people to setup wireless sensor networks or get started in embedded wireless communications. Check it out on the link below. [via]

This project is a garage status monitor that is able to tell when the garage door is open or closed and also monitor the ambient temperature. It is based on an Arduino board, a XBee module and a LM36 sensor. The garage door status is sensed by a roller contact switch, data is handled by a Windows Service and displayed over the web. [via]

This project is a speed detector based on Arduino platform. Arduino is measuring the time it takes an object to travel between two points and transmit this data to a computer or smart phone where it is converted to speed value and presented in a clear way. Check more details on code on the site below. [via]

This project is a Real time clock shield for Arduino based on DS1307 realtime (RTC) integrated circuit. It is a fairly accurate clock that can keep time when not powered if you add a 3V battery. Data is transfered to microcontroller through I²C bidirectional interface. It is connected to Arduino at pins 4 and 5. Check schematic on the link below.

This project shows how to build an Open source hardware GPS based on GeoShield and Arduino and if you combine it and a TouchShield Slide, you have a completely portable DIY GPS. Check details of this project on the link below.

This project consists of LED strips mounted on an outdoor trellace which functions as a lightning simulator, outdoor breathalyzer, graphic equalizer synced to music, and a few other effects with sound. The system is controller by an Arduino. [via]

This page describes the assembly, programming and use of a device that constantly monitors heart rate and stores the data on an SD memory card. The data can be read from the card, imported into MS Excel (or other programs) for graphing or other analysis. I use this device to track my effort level on bike rides.

This project is based on netduino and is able to interpret morse code into readable words. The app is “looking” at the morse code, measure the pulse and pause widths and convert them back into words.

Toolduino is a simple software tool that lets you easily interact with your Arduino hardware so you can test the circuits you create. Toolduino uses the the Arduino library for Processing to communicate with an Arduino board so you can manipulate output pins and read inputs.

Hackvision is a simple, retro gaming platform based on Arduino technology that you can assemble and connect to your TV. You can write you own games and make your own controllers! The best of all is that is open source and you can find schematics, boards and source code on the site below.
