Times really flys when you're having fun - it has been more two years since I posted this journal entry about how to double the Arduino board's Flash memory by replacing the ATmega8 with an ATmega168 microcontroller. Lots has changed since then, e.g. the Arduino project now includes several board designs and layouts, most of which feature the ATmega168.

For the last couple of months now, the even better AVR 8-Bit RISC ATmega328P micro-controller was hard get. However, it's now more broadly available and four of these 8-Bit Micros have arrived today, shipped form one of my favorite Online-Electronics stores: SparkFun. The ATmega328P features 32 KBytes of Flash, 2 KBytes of RAM, and 1 KByte of EEPROM a nice improvement over Arduino's original configuration with an ATmega8: (8 KBytes of flash, 1 KByte of RAM, and 512 Bytes of EEPROM).
Time to revisit the Arduino Project, an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software, intended for anyone interested in creating interactive objects or environments.
