I worked extensively on the ATMEL AVR family of controllers from 2005-2008. My major projects were:
2. A Micromouse
3. SD/MMC Library and Bootloader for Atmega32
4. Handheld E-Book Reader
5. A Quick tutorial on getting started with AVR controllers, from the seminars/ workshops I took in VIT in 2006-08.
This is one of my development boards, for an ATmega32, with and without the large LCD panel attached.
