The entire system consists of three main function blocks: The AVR as the central CPU running the high level network routines including the TCP/IP stack. The second main block is the compact flash WLAN card running all the low level network functions including encryption. The third block is a XC9572XL CPLD, a programmable logic device that forms the spi2cf interface between the AVRs SPI and the CF card. It is mainly doing the translation between the SPI interface used to connect to the AVR and the parallel interface used on the compact flash slot.

WIMP is a project developed by 5 students as the 4th year project and supervised by Professor Trevor W. Pearce of the Department of Systems and Computer Engineering at Carleton University. But, what the heck is WIMP ? As the title says its a wireless interactive media player, basically a MP3 stereo system with a wireless link to a PC. Currently the students are still working on the project, but I can see some serious applications, for this system in the future, so good luck guys in finishing the project and scoring nice grades.

This simple ATtiny45 based wireless security system includes a ZigBee wireless door sensor and a PC interface. When a door opens or closes, the ATtiny45 sends a message to the PC interface.

For those of you who dont know why you need to add an external antenna to a router, its because the WRTSL54GS doesn’t have an external antenna like most wifi routers have. The job is quite simple, all you need is an antenna and its plug preferable with a pigtail attached to it. You just need to solder the pigtail by following the instructions.

This is the latest wireless accelerometer from SparkFun. The WiTilt v3 incorporates many new features including LiPo battery, built-in charger, enclosure, single axis gyroscope and many more! When combining the triple axis accelerometer sensor from Freescale MMA7260Q with the Bluetooth module from Roving Networks what do you get? The new, WiTilt v3 complete wireless Accelerometer Measurement System. All measurements are transmitted via a wireless Class 1 Bluetooth link that is extremely easy to use with a range of 100m (330ft) line-of-sight and 30m (100ft) in doors.
