Pyxis OS for Arduino.

Instead flashing new program to your arduino internal flash storage, you can now copy the application binary to the SD card and run on the arduino. With the help of Pyxis OS, you will turn your arduino to be a PDA like system. You can have advanced graphics APIs and also run applications from SD card. The biggest problem is that you only allow to write the application in the Pyxis OS specific programming language:( But it is still cool.



In their website, they provide a free PFAT implementation for turning the EEPROM to a file system in AVR. it is free:)

Old tape counter reborn with Ardunio.

The tape counter exists in old cassette player, but nowadays we will see LCD display rather than this old mechanic design. But we all love old days, it is awesome to see the tape counter is getting a remix with arduino:)

Cheap wireless communcation with Infrared.

JSR,self-taught artist, made a cheap wireless communication circuit for his music project using adruino, he made a simple circuit to convert the normal UART port to infrared signals. A wireless serial port is born! The circuit and codes are simple, please check out jacob's website here.


For the transmitter, looks like:

Very simple and clean!

ARDUWAY - Segway-like lego bot with Arduino Brain.

ADRUWAY is a segway-like, self balancing two wheels bot, which used a gyroscope to detect the tilt angle motion. Let's check out the cool video here:

Digital Compass with AVR (Arduino)

Digital compass is a magnetic sensor which gives you the heading direction, which may be useful for your robotic projects. I have tried it with my HTC G1, which has the digital compass built-in, and working very well with Google map.

One common digital compass sensor available on the market is Honeywell's HMC6352 which is a fully integrated sensor, it is very easy to use. You can use I2C to connect to your microprocessor, by sending a simple character 'A' to the sensor, it will return you the heading information. Near Future Laboratory has an example on using arduino and HMC6352, source codes are also available. Please check it out on the links below!
