James Bowman is a creator of first Gameduino. This time is his Gameduino (version 2) based on a FTDI chip FT800 EVE (instead of Xilinx FPGA), which provides a full featured OpenGL-like GPU for TFT touch displays, connected through I2C/SPI interface. James added some “bijou”, like an accelerometer, SD card slot and sound output.
1-Wire bus is really interesting piece of electronic design by Dallas Semiconductor. It provides two-way serial connection on 1 wire (technically two, of course – don’t forget the common ground). There are a lot of devices use 1-Wire interface, from simple thermometers to ID buttons with memory. Fredrik Lindberg shows how to make an 1-Wire bus master device which can communicate through IPv6. His device is based on an Atmel AVR ATmega644 and the ENC28J60 Ethernet controller from Microchip. With this you can address your 1-Wire devices through Ethernet connection.
